Paul Kossoff Guitars & Gear: The Complete Guide

He was 20 years old, standing on a stage at the Isle of Wight Festival in front of an estimated 600,000 people, holding a Les Paul that had been stripped down to bare wood — and he played like a man twice his age who’d already survived something terrible.

That’s Paul Kossoff. Five foot nothing, painfully shy offstage, a force of geological magnitude when he plugged in. While Eric Clapton and Jimmy Page were collecting all the magazine covers, Kossoff was quietly doing something that neither of them could fully replicate: he was making every single note sound like it might be the last one he’d ever play.

The vibrato. The sustain. The way he’d dig into a bend and hold it there while the Marshall stacks pressurised the room around him. Angus Young has cited him. Joe Bonamassa built a career chasing echoes of his tone. Gary Rossington of Lynyrd Skynyrd said plainly: “Paul Kossoff was a major influence. Hell, to anyone back then interested in heavy blues guitar, Paul was a big influence.”

He died at 25. He left behind a handful of records and a guitar tone that nobody has ever fully replicated.

This is his gear. This is the story behind the sound. And this is why it still matters.

Background: Six Years of Classical Guitar, One Night with Clapton, and Everything Changed

Paul Francis Kossoff was born on 14 September 1950 in Hampstead, London, into a theatrical family. His father David Kossoff was a celebrated British actor. The household was cultured, intellectual, and probably not expecting to produce one of the rawest blues-rock guitarists that England would ever generate.

At age nine, Kossoff began classical guitar lessons with Blanche Monroe. He studied for six years — until he was fifteen — developing the technical foundation of finger control, phrasing discipline, and tonal awareness that would later become the backbone of his electric style. That classical training is no footnote. It explains the precision of his vibrato, the economy of his note choices, and the way each phrase feels complete and considered rather than improvised and abandoned.

In December 1965, everything shifted. Kossoff attended a show by Eric Clapton with John Mayall’s Bluesbreakers at The Refectory in Golders Green, North West London. He was 15 years old. What he heard that night rewired his nervous system. He walked out wanting a Gibson Les Paul — the same guitar Clapton was playing — and soon went to work at Selmer’s Music Shop on Charing Cross Road, saving up for the real thing.

His first Gibson was a 1957 Les Paul Junior in TV Yellow — the cheapest one he could find. Then came a 1954 Les Paul Custom with dual P-90 pickups, allegedly previously owned by Clapton himself. Kossoff spent hours bent over it, transcribing blues licks, studying every bend and slide and vibrato gesture he could find on record.

In 1966 he formed the blues band Black Cat Bones, hitting the London club circuit. The band supported Fleetwood Mac regularly, and Kossoff spent hours jamming with Peter Green — another guitarist whose economy and emotional depth would leave a permanent mark on his approach. In the audience at one Black Cat Bones gig, drummer Simon Kirke heard something he’d been looking for and collared Kossoff at the bar afterward.

In April 1968, Kossoff and Kirke teamed up with vocalist Paul Rodgers and bassist Andy Fraser to form Free. Kossoff was 17 years old. He’d been playing electric guitar for barely two years. He sounded like he’d been doing it for twenty.

Paul Rodgers, who heard Kossoff jam for the first time at a blues club in Finsbury Park, described it precisely: “He brought his guitar in and we jammed — a really heart-stopping jam. We did ‘Stormy Monday Blues,’ B.B. King, and a couple of other things, and it was like time stood still. When we came off stage I said to him, ‘Man, we have to form a band.'”

Tone note: Six years of classical training taught him how to listen to himself. One night with Clapton taught him what to do with it.

The Rig: Paul Kossoff’s Guitars, Amps & Gear — Complete Era-by-Era Breakdown

Kossoff’s gear story is deceptively simple on the surface — Les Paul, Marshall, done — but underneath that three-word summary lies a surprisingly detailed history of specific guitars with specific histories, amp choices that varied more than the mythology suggests, and a vibrato-obsessed player who worked harder on tone than most people realize.

Guitars: Bursts, Customs, and the One That Changed Hands with Clapton

The Early Guitars: Building Toward a Burst

Before the famous Les Pauls came a chain of instruments that tell the story of a teenager working his way up toward the guitar that would define him. First, a cheap Eko 500 electric — his first guitar ever, with what he described as a “lame gold finish.” Then the TV Yellow Les Paul Junior purchased after months of savings from the Selmer’s job. Then the 1954 Les Paul Custom with P-90 pickups — allegedly once owned by Clapton — which he played through his Black Cat Bones years and into the earliest days of Free.

The Custom featured a P-90 single-coil in the bridge and a “staple” Alnico P-90 in the neck position. It wasn’t the humbucker sound he was chasing — it was still more on the jazz side of the tonal spectrum — but it got him to the gigs and taught him the guitar’s architecture while he saved for something better.

The “Kossoff Burst” — The 1959 Gibson Les Paul Standard

In spring 1969, Kossoff acquired a 1959 Gibson Les Paul Standard sunburst. The exact circumstances of the acquisition are unclear — likely a trade, given his limited finances at the time — but what happened next with that guitar is one of the most documented and mythologised instrument stories in British rock history.

At some point early in his ownership, Kossoff — or possibly a previous owner — stripped the sunburst finish from the maple top down to the bare wood and applied a clear coat. The result was what became known as the “Stripped Top” or “Kossoff Burst” — a natural-finish Les Paul Standard that showed the raw, figured maple top in all its full-grain glory. The back retained traces of brown finish, and red lacquer residue in the control cavity points toward the guitar having been a sunburst originally.

This is the guitar seen at the Isle of Wight Festival on 30 August 1970, where Free performed before an estimated 600,000 to 700,000 people alongside The Who and Jimi Hendrix. It is almost certainly the guitar heard on “All Right Now.” And its PAF pickups — measured at 8.52kΩ in the neck and 7.43kΩ in the bridge, with rare Alnico III magnets — are a significant part of why that tone sounds the way it does. Open, dynamic, harmonically complex, and responsive to the lightest touch of vibrato.

The guitar’s story becomes tragic from 1974 onward. As Kossoff’s drug addiction tightened its grip, he was forced to sell instruments to fund his habit. The Kossoff Burst was sold to a man named Mike Gooch for £500 in September 1974 — with frets so badly worn that Gooch’s father gave him an earful for spending that much on a beaten-up guitar. Kossoff tried and failed to buy it back in 1975. He died in 1976 without recovering it.

Gibson recreated the guitar in 2012 as a limited edition Paul Kossoff 1959 Les Paul Standard reissue, using their own analysis of the original instrument — including those Alnico III PAF pickups — to capture the specific resonance and tonal character that made it legendary.

Tone note: The stripped top isn’t cosmetic. Removing the original lacquer changed the wood’s resonance — more open, more responsive, more alive. Kossoff’s best tone may have been partly accidental.

The 1958 “Darkburst” — The Clapton Trade

Around July or August 1969 — while Blind Faith was on their ill-fated US tour — Kossoff traded his 1954 Les Paul Custom to Eric Clapton in exchange for a dark-burst 1958 Les Paul Standard. The exact guitar Clapton received has been debated ever since: Clapton later gave a three-pickup Les Paul Custom to Albert Lee around 1979, but whether that was the Kossoff Custom or a different instrument has never been conclusively established.

What is clear is that the 1958 darkburst became part of Kossoff’s Les Paul arsenal during the Fire and Water and Highway era, adding another flavour of late-’50s PAF tone to his studio palette. The darkburst Les Pauls from 1958 tend to have a slightly warmer, darker character than the brighter 1959 flametops — different Alnico magnet grades, different wire tensions in the pickup winding, subtle variations that add up to a perceptibly different voice.

The “Stripped Top” Les Paul — The Isle of Wight Guitar

Separate from the Kossoff Burst above — or possibly the same guitar, depending on which account you follow — there is the stripped-down natural-finish Les Paul that Kossoff played at the Isle of Wight and used for the Top of the Pops performance of “All Right Now.” Its exact birth year (1958, 1959, or 1960) remains contested due to a missing serial number lost during a refinish. Kossoff sold this guitar in September 1974 for £500 to Mike Gooch, who later sold it to Arthur Ramm for £1,000. Its current owner remains anonymous.

The 1959 “Kossoff Burst” — The Broken and Traded Guitar

A second documented 1959 Les Paul Standard featured in Kossoff’s collection and met a dramatic end. At the conclusion of Free’s final concert in 1972 — the night the band effectively split — Kossoff threw the guitar into the air and walked away as it came down, splitting the headstock. He then walked to Arthur Ramm, whose band Beckett had been the support act, and swapped the damaged 1959 for Ramm’s 1968 Les Paul Goldtop sitting in the dressing room. The broken Burst was repaired by London luthier Sam Li, with the repair unfortunately causing the original headstock serial number to be lost.

The 1954 Les Paul Custom (Black Beauty) — The Clapton Guitar

This was Kossoff’s prized possession through his Black Cat Bones years and the early days of Free. A pre-humbucker Custom equipped with P-90 pickups — allegedly once owned by Clapton — it gave him a biting, jazz-adjacent tone that contrasted with the warmer sunburst Standards. He eventually traded it to Clapton for the 1958 darkburst in 1969.

Other Guitars in Kossoff’s Collection

Gibson ES-335 (block-neck, 1960s) — Used during the Fire and Water era for specific layered tones; contributes the warm semi-hollow character audible on certain Free album tracks.
Gibson Les Paul Custom (mid-1950s, three pickups) — A separate black three-pickup Custom used alongside the Bursts during Tons of Sobs sessions through Marshall and Laney amps.
Fender Stratocaster (White, composite) — A 1957 Stratocaster neck on a 1960 body with 1964 pickups and a mint-green pickguard. Used in the “My Brother Jake” video (1970) and on the cover of his solo album Back Street Crawler. This is likely the guitar subsequently purchased by Dave Murray of Iron Maiden for £1,400 in 1976 — a fact that tells you everything about the calibre of what Kossoff owned.
Various additional Les Paul Bursts (1958–1960) — Kossoff owned and played multiple ‘Bursts over his career, a tigerstripe 1958/59 used with Black Cat Bones, a bright-red 1960 sunburst (seen in “The Stealer” video), and others that passed through his hands as addiction forced sales.
Gibson Hummingbird / Guild Acoustic — Acoustic guitars used for songwriting. In his final 1976 interview with Guitar Player, he mentioned a Guild given to him by the Back Street Crawler members when he was ill, which he called the best acoustic he’d ever owned.
Gibson Les Paul Junior (TV Yellow, 1957) — His first proper Gibson, purchased from savings earned at Selmer’s.

Amps & Cabinets: Marshalls, Laneys, and the Cabinet He Built with His Father

For most of Free’s career, Kossoff’s live amp was a Marshall. For much of Free’s recording career, the picture is more complicated — and more interesting.

Marshall Super Bass 100W — The Primary Live Amp

Multiple sources confirm that Kossoff preferred Marshall Super Bass heads rather than Super Leads for his live work — a choice that surprises some people but makes tonal sense. The Super Bass has slightly different EQ characteristics to the Super Lead: a fuller, rounder low-midrange response, marginally less high-end brightness, and a power section that sags differently under load. For a guitarist whose entire vocabulary was built on sustain, vibrato, and thick midrange bloom, the Super Bass delivered a more vocal, less cutting character than the typical guitar head.

He ran these through Marshall 4×12 cabinets loaded with bass speakers — specifically G12H Celestion drivers — rather than standard guitar speakers. This was reportedly a deliberate choice: he felt the bass speakers gave a rounder, more saturated response that matched how he heard his tone in his head. The combination of Super Bass head into bass-spec cabinet gave Kossoff’s live sound that particular thickness — huge but never harsh.

Famously, Kossoff and his father David built one of his Marshall cabinets themselves. David Kossoff, the celebrated British actor, apparently assisted his son in constructing a speaker cabinet — a detail that humanizes both men considerably.

Tone note: Super Bass head, bass speakers. It’s rounder, darker, and thicker than the standard Marshall guitar setup. That’s not an accident — it’s the architecture of the All Right Now tone.

Marshall Super Lead 100W — The Stage Partner

Alongside the Super Bass, Kossoff used Marshall Super Lead 100W heads — the standard Plexi circuit — particularly during Free’s first tour. Photos from the Isle of Wight and Top of the Pops show Marshall stacks clearly. The Super Lead gave a brighter, more aggressive cut to the high mids that balanced the rounder Super Bass character when both were in use.

Laney Amps — Early Studio and Occasional Live Use

Laney amplifiers appear in the early Free recording documentation, used alongside the Marshalls during the Tons of Sobs sessions. Laney in the late 1960s was producing Plexi-circuit derivatives that shared some of the Marshall character but with their own tonal identity — slightly looser, slightly warmer in the bottom end. Kossoff’s use of them during the debut album sessions adds another tonal layer to the early Free sound that is often overlooked.

Selmer Treble and Bass 50 — The “All Right Now” Studio Amp (Contested)

There is credible forum testimony, albeit unverified, that Kossoff used a Selmer Treble and Bass 50 for the studio recording of “All Right Now” rather than a Marshall. The Selmer T&B 50 is a British valve amp from the 1960s with a particularly warm, compressed character — less gainy than a Marshall but with exceptional bloom and sustain. Players who have tried replicating the Fire and Water studio tone with period-correct Selmers report that it captures something the Marshall references miss. It remains speculative but is worth noting for anyone serious about chasing this specific sound.

Fender Tremolux — Studio Experimentation

During the sessions for Free (the second album, 1969), Kossoff began experimenting with different equipment including a Fender Tremolux amp — a lower-powered American tube combo with a characteristic tremolo circuit and cleaner, more Fender-voiced response. Its use appears on specific tracks where a cleaner, less British character was needed.

Orange OR100 / Matamp — Brief Appearances

Orange amplifiers appear in footage from 1970 — an OR100 visible in Beat Club footage and a Matamp visible during other period footage. These appear to be studio or broadcast-setting amps rather than core touring equipment. Both the OR100 and Matamp share a circuit lineage and deliver a characteristically warm, compressed British valve tone that would have suited Kossoff’s playing style, but neither became a primary amp in his rig.

Leslie Cabinet — Studio Effect

A Leslie rotating speaker cabinet appears in the signal chain on select tracks from Kossoff/Kirke/Tetsu/Rabbit (1972) and Free at Last (1972). The Leslie adds a swirling, frequency-shifting modulation that gives certain guitar parts an almost organ-like quality. Kossoff used it as a texture rather than a standard effect — specific tracks, specific moments.

Amp	Era	Notes
Marshall Super Bass 100W (Plexi)	Free touring era (1968–1972), primary	Preferred over Super Lead for rounder, thicker midrange response. Run into bass-spec Celestion G12H speakers.
Marshall Super Lead 100W (Plexi)	Early Free tours (1968–1969)	Primary live amp before Super Bass preference established; visible in Isle of Wight footage
Laney (late 1960s model)	Tons of Sobs (1968) sessions	Used alongside Marshalls in the recording of the debut album
Selmer Treble & Bass 50	Possibly Fire and Water (1970) studio sessions	Contested but credible; warm, compressed British valve tone; may be the “All Right Now” studio amp
Fender Tremolux	Free (1969) sessions	Studio experimentation; American clean tone for contrast tracks
Orange OR100 / Matamp	Studio/broadcast appearances, 1970	Seen in Beat Club footage; likely venue/studio equipment rather than core touring rig
Leslie Cabinet	Kossoff/Kirke/Tetsu/Rabbit (1972), Free at Last (1972)	Rotating speaker effect used on select tracks
Marshall 4×12 Cabinet (G12H Celestion bass speakers)	Free touring era	Bass-spec speakers chosen deliberately by Kossoff for their rounder, thicker response

Pedals & Signal Chain: Minimal, Purposeful, Lethal

Kossoff’s pedalboard philosophy was pure and uncompromising: if it doesn’t serve the song, it doesn’t get plugged in. For most of the Free era, the signal chain was simply guitar into amp. Full stop. The tone lived in his hands, in the vibrato, in the weight of the pick strike, in the way he rode the guitar’s volume knob to shift between clean and saturated.

Wah pedal (Vox or Dunlop Crybaby type) — Used on specific tracks. The earliest documented appearance is at Morgan Studios in May 1969 during sessions likely for “I’ll Be Creepin'” or “Sugar For Mr Morrison.” The wah appears occasionally in live footage, used as an expressive accent rather than a rhythmic effect.
Leslie Cabinet / Rotary Effect — As noted in the amp section, used in the studio on select recordings for swirling modulation.
Echoplex (reported) — A tape echo unit reportedly used in certain live contexts. Not a consistent presence but documented in period accounts.

That is essentially the complete list. No fuzz box. No overdrive pedal. No delay chain. Kossoff’s distortion came entirely from driving tube amplifiers with hot pickups at volume — the classic British approach of using amp gain rather than pedal gain as the primary distortion source. His tone was, as one Guitar World analysis put it, “driven, rather than distorted.” The distinction is everything: driven means the amp is working hard and just starting to break up; distorted means the signal is compressed and saturated. Kossoff lived in the driven zone, which is why each note has that elastic, pressurised quality — right on the edge of losing control, but never quite there.

Tone note: No pedals between guitar and amp means every dynamic nuance of the playing comes through unfiltered. It’s the most honest signal chain in rock. It’s also the most unforgiving.

Strings, Picks & Setup

Strings: Heavier gauge than most of his contemporaries. Kossoff reportedly favoured heavier strings because they gave him more resistance to work against — critical for a vibrato technique built on sustained, controlled bending with the index finger. Heavier strings under more tension produce more sustain and a fuller low-end response when pushed into the amp. The exact gauge is not definitively documented, but accounts consistently place him at .011s or heavier.

Picks: Also heavier than average — again, for the same reason. More resistance, more tone, more sustain per note. He needed the string to fight back. That physical resistance was the training tool for the vibrato that became his signature.

Setup:

PAF-equipped Les Paul Standards with original or closely matched Alnico III humbuckers
Pickup height set for maximum output without losing clarity — the PAFs at those impedance readings (8.52kΩ neck, 7.43kΩ bridge) respond to height adjustment significantly
Bridge pickup for the majority of his playing — the characteristic midrange bite of a PAF bridge pickup is central to the “All Right Now” riff character
Guitar volume knob actively used for dynamic control — from full clean to edge-of-breakup to saturated, all managed through the guitar’s own output control into the hot Marshall input

Tone note: Heavy strings, heavy pick, high-output PAFs. Everything in Kossoff’s setup was designed to create resistance — because resistance is what produces that exquisite, controlled tension in every note.

Tunings & Tone Philosophy

Standard E tuning for virtually the entire Free catalog. No alternate tunings, no dropped voicings — the harmonic complexity came from his chord voicings and single-note choices, not from tuning workarounds.

Kossoff’s tone philosophy, expressed in his own words from a 1976 Guitar Player interview, is as honest as his playing: “I like to move people. I don’t like to show off. I like to make sounds as I remember sounds that move me.”

He was, by all accounts, deeply insecure about his technical abilities relative to the players he admired — Clapton, Green, Beck — and that insecurity drove him into an obsessive focus on the elements he could control: vibrato, sustain, emotional intensity. He reportedly said that Paul Rodgers was his biggest teacher and that their styles grew up together. “I hate to play solos,” he admitted. “I prefer to hear his voice, back it around, push it.” For a player whose guitar solos are regularly cited among the greatest in British rock, that level of self-deprecation speaks to both his personality and his fundamental musical philosophy: serve the song, serve the singer, make every note matter.

Tone note: Kossoff didn’t practise scales. He practised emotions. The difference is audible in every bar he ever recorded.

Playing Style & Tone Philosophy: The Vibrato, the Space, and the Gospel of Restraint

There are guitarists who can play more notes than Paul Kossoff. There are guitarists who can play faster, more accurately, with more technical range and more genre fluency. None of them have ever quite made a single, held note feel the way Kossoff could make a single, held note feel.

That’s the mystery at the centre of his playing, and it begins with the vibrato.

The Vibrato — The Unmistakable Signature

Kossoff’s vibrato is one of the most discussed and least successfully imitated techniques in rock guitar history. It is fast — unusually fast for a player of his era, most of whom favoured wide, slow vibrato in the B.B. King tradition. But it is also controlled: not a nervous shake or a random wobble, but a deliberate, rhythmically precise oscillation that adds a vocal, almost crying quality to sustained notes.

He used his index finger for vibrato, backing it up with the ring finger for additional strength and control. In his own words: “I trill with my first, middle and ring fingers, and bend chiefly with my small finger. I’ll use my index finger when I’m using vibrato.” This is not the standard blues approach (which typically uses the ring finger for vibrato while the first finger holds down the fret). It’s a technique he developed himself, refined over years of deliberate practice, and that produces a distinctly different quality of movement — faster, tighter, more insistent.

Simon Kirke described it simply as the ability to “cry every note.” That is as accurate a description as any technical analysis.

Tone note: His vibrato was never decoration. It was the emotional content of the phrase, delivered through physical technique.

The Space — Less As Statement

Free were a four-piece with two of the best players in British rock in Andy Fraser (bass) and Paul Rodgers (vocals). Kossoff understood intuitively that his role was not to fill every available frequency — it was to occupy the space that the other three left open, and to make that space count.

His solos are models of restraint. Listen to “All Right Now,” “Mr. Big,” “Fire and Water” — the guitar lines are melodic in the songwriting sense, not in the improvisation sense. He’s not running scales. He’s singing. Each phrase has a clear beginning, development, and resolution. He’ll land on a note, apply the vibrato, hold it for what feels like an entire geological era, and then move to the next one.

That approach to space — leaving room between phrases, letting the amp breathe, allowing sustained notes to complete their natural decay before the next one arrives — creates the hypnotic, pressurised quality that defines Free’s best material. It is blues phrasing in the deepest sense: not fast, not busy, not demonstrative. Just true.

Tone note: Kossoff understood that silence between notes is not absence. It’s tension. And tension is what makes the next note matter.

Unorthodox Chord Voicings — Filling the Power Trio

Free operated as a power trio plus vocals, which meant Kossoff was periodically responsible for filling the harmonic space that a rhythm guitarist in a four-piece would normally cover. His solution was a set of unorthodox chord voicings — partial barre chords, two-note fragments, open strings ringing against fretted notes — that created a deceptively full sound from a single guitar.

Guitar World noted: “He used open strings left to ring against fretted ones, which really helps fill out the sound.” This technique turns a simple pentatonic phrase into a chord-like texture — the open string providing a drone while the fretted note carries the melodic content. It’s a classical guitar technique adapted to electric blues-rock, and it is one of the specific elements of his style that is hardest to replicate without understanding its architectural purpose.

Tone note: He filled out the band’s sound not by adding more guitar — but by adding smarter guitar.

The Pick Attack and Dynamic Range

Kossoff used a heavy pick and heavy strings specifically to maximise his dynamic range. The heavier the pick and string gauge, the greater the difference in output between a light touch and a hard attack — giving him a wider palette of expression from the same note on the same guitar. He could ghost a chord, barely grazing the strings, and produce a warm, clean whisper. He could dig in with full force and push the Marshall’s input stage into early breakup. All of this was available without touching a single knob.

Tone note: Heavy strings, heavy pick, and a hot amp running clean. The dynamic range lives in the space between a light touch and a hard one.

How to Sound Like Paul Kossoff: Chasing the All Right Now Tone

Here is the uncomfortable truth about replicating Paul Kossoff’s tone: the gear is the easy part. A Les Paul with PAF-style humbuckers into a cranked Marshall Plexi will get you into the same postcode. Getting to the same street requires developing a vibrato technique that most players spend years trying to master and never fully achieve.

That said — the gear matters, and here’s how to set it up properly.

The Guitar

A late-’50s spec Les Paul Standard with PAF-style humbuckers is the foundation. For the classic Fire and Water era tone, you want:

Low-to-medium output humbuckers — PAF spec, around 7–8.5kΩ, Alnico II or III magnets
Mahogany body with maple cap for the characteristic Les Paul warmth-plus-brightness balance
Rosewood fretboard for additional warmth in the upper register where Kossoff lived
Bridge pickup for the “All Right Now” riff; neck pickup for the warmer solo passages

Modern equivalents: Gibson Les Paul Standard (50s spec), Gibson Custom Shop ’59 Les Paul, or — for the closest PAF approximation — any quality Les Paul with handwound PAF-clone pickups (Wizz P.A.F., Throbak, Sheptone). The Gibson Paul Kossoff 1959 Les Paul Standard Limited Edition (2012) used Alnico III magnets specifically to match the measured specs of the original Kossoff Burst.

The Amp

British, high-gain, and running hot. A Marshall Plexi-circuit amp — Super Bass circuit preferred over Super Lead for the rounder, thicker character Kossoff favoured. Dime the volume. Let the tubes do the work.

Control	Setting	Notes
Volume (both inputs)	8–10	The amp needs to be working hard. This is not a bedroom tone.
Bass	3–4	Tight; Andy Fraser’s bass covers the low end
Middle	7–8	The core of the Kossoff tone lives here
Treble	5–6	Present but not sharp; the PAFs handle the brightness
Presence	4–5	Moderate; you want bloom, not cut

Consider loading your 4×12 cabinet with bass-spec Celestion G12H speakers rather than standard guitar speakers — this is what Kossoff did, and it contributes meaningfully to the warmer, less aggressive top-end character of his live tone.

Tone note: If the amp is comfortable, it’s not loud enough. Kossoff’s tone required the amp to be under real stress.

The Pedals

You don’t need any. That is not rhetorical — Kossoff genuinely ran guitar straight into amp for most of his career. If you want to add a wah for specific tracks, a classic Vox V847 or Dunlop Crybaby is period-correct. That’s the entire list.

Budget vs Pro Rigs

Budget Rig:

Guitar: Epiphone Les Paul Standard with Alnico Classic Pro humbuckers (or swap to PAF clones)
Amp: Marshall DSL40CR or Origin 50H — set gain low, volume high, mids up
Pedals: None required. Maybe a wah for specific songs.
Strings: .011–.049 or .011–.052 — go heavier than you’re comfortable with
Pick: Heavy gauge — 1.0mm or thicker

Pro Rig:

Guitar: Gibson Les Paul Standard (’50s spec) or Custom Shop ’59 Les Paul with Alnico III PAF-spec humbuckers
Amp: Marshall 1959SLP or 1987X Super Lead (or Super Bass circuit equivalent), run wide open into 4×12 with Celestion G12H bass speakers
Pedals: Vox V847 Wah for select tracks
Strings: D’Addario or GHS .011 gauge or heavier

The Technique — The Inescapable Truth

None of the above matters without the vibrato. Specifically: a fast, index-finger-driven vibrato, with the ring finger providing additional support and stability. Practice it slowly. Develop speed gradually. Work on keeping it rhythmically consistent — Kossoff’s vibrato has an internal pulse that is neither random nor metronomic. It has musical intent.

Beyond that: play fewer notes than you think you should. Leave space after phrases. Let the amp breathe. Let the string decay completely before you hit the next one. Trust the silence.

Tone note: The gear gets you into the building. The vibrato gets you into the room. The space is what the music actually lives in.

Influence & Legacy: The Ghost in Every Bend

Paul Kossoff died on 19 March 1976, on a flight from Los Angeles to New York. He was 25 years old. A pulmonary embolism — a blood clot in the lung — brought on by years of drug abuse and the physical deterioration that came with it. He had been clean, or trying to be clean, for periods near the end. It wasn’t enough.

In 2010, Rolling Stone ranked him number 51 in their list of the 100 Greatest Guitarists of All Time. In 2025, Bad Company’s Rock and Roll Hall of Fame induction — with Paul Rodgers and Simon Kirke on stage, both of whom came from Free — included tributes to Kossoff explicitly, acknowledging that his contributions to what became Bad Company’s sonic foundation could not be separated from the story. A companion album honouring him was released in October 2025.

The names who cite him read like a hall of fame in themselves. Angus Young — who has been described as sharing Kossoff’s face-pulling, physicality-first approach to vibrato in ways too obvious to be coincidental. Joe Bonamassa, who has demonstrated Kossoff’s signature bends and vibrato in instructional content and described the Kossoff Burst as a pivotal influence on his tone-chasing philosophy. Robin Trower, who shared the same British blues-rock circuit. Gary Rossington of Lynyrd Skynyrd. Warren Haynes. Pat Travers. Paul Weller. The list goes on.

What Kossoff gave rock guitar was a demonstration that emotional intensity and technical simplicity are not opposites. You don’t need a thousand notes to break someone’s heart. You need one note, held long enough, with enough intention behind it, vibrating with enough of yourself in it, that the person listening feels something they weren’t expecting to feel.

He was never comfortable with the comparisons to Clapton and Green and Beck. Andy Fraser, his bassist and closest musical partner, recalled: “He felt intimidated by those other guitarists, and when people began speaking of him in terms of Clapton and so on, it frightened him. Drugs were a defence, his excuse.” It is one of rock’s most painful ironies that a guitarist who could cause Clapton to trade a 1958 Les Paul for one of Kossoff’s guitars couldn’t hear his own greatness clearly enough to survive it.

The Kossoff Burst sits in someone’s anonymous collection now, unplayed or barely played, its stripped maple top still carrying the resonance of every note he put through it. The music is still there — Fire and Water, “All Right Now,” “Mr. Big,” “The Stealer,” the Back Street Crawler recordings that some consider his most emotionally complete work.

Every guitarist who has ever spent an hour trying to nail that vibrato technique — and given up, and tried again the next day — is part of his legacy.

Tone note: He didn’t change what rock guitar sounded like. He changed what it felt like. That’s the harder thing to do.

There’s a photograph from the Isle of Wight Festival in 1970. Paul Kossoff is 19 years old. He’s holding the stripped-down Les Paul in front of what would eventually be estimated at 600,000 people. His expression is not the one of a rock star enjoying his moment. It’s the expression of someone doing the only thing that makes sense to them — the only thing that quiets the noise.

He played “All Right Now” that day, and the place went nuts. He played “Mr. Big,” and “Be My Friend,” and probably got through a dodgy cable dropout at some point, because that’s what the footage shows. He played with the conviction of someone who understood, even at 19, that the notes in between the silence were borrowed time.

In his final interview, he said: “My vibrato is finally starting to grow up.”

He died three months later.

What he left behind — the recordings, the technique, the stripped Burst, the ghost of that vibrato in every blues-rock guitarist who came after him — is proof that you don’t need a long life to build a permanent one. You just need to mean every note you play.

All right now.

If Kossoff’s Les Paul into Marshall philosophy has you wanting to go deeper into the Burst tradition, check out our complete breakdown of Angus Young’s tone and rig — another player who built a career on SG or Les Paul into cranked Marshall, pursuing his own version of that British voltage gospel.

And for the closest spiritual successor to Kossoff’s “fewer notes, more feeling” approach in a different era, don’t miss our deep dive on Stevie Ray Vaughan’s complete gear history — a player who understood, just as Kossoff did, that tone lives in the conviction behind the note, not the number of them.

FAQ: Paul Kossoff Guitars & Gear

What guitar did Paul Kossoff use on “All Right Now”?: Almost certainly the stripped-down natural-finish Les Paul Standard known as the “Kossoff Burst” — a late-1950s ‘Burst that had its sunburst finish removed down to bare maple, later clear-coated. It was the guitar Kossoff used at the Isle of Wight Festival in 1970 and on the Top of the Pops performance of “All Right Now.” It featured PAF humbuckers measuring 8.52kΩ neck and 7.43kΩ bridge, with Alnico III magnets. It was sold by Kossoff in 1974 for £500 and its current owner remains anonymous.
What amp did Paul Kossoff use with Free?: Primarily Marshall Super Bass 100W heads, which he preferred over Super Leads for their rounder, thicker midrange response. He ran these into 4×12 cabinets loaded with bass-spec Celestion G12H speakers rather than standard guitar speakers — a deliberate choice that contributed to the full, warm character of his live tone. Marshall Super Leads also appear in early Free footage. Studio recordings may have used a Selmer Treble and Bass 50 for specific tracks including possibly “All Right Now.”
What is the “Kossoff Burst”?: The “Kossoff Burst” refers to Paul Kossoff’s primary 1959 Gibson Les Paul Standard, which had its sunburst finish stripped to bare maple wood. It featured original PAF humbuckers with rare Alnico III magnets. Kossoff acquired it in spring 1969 and it became his main guitar through Free’s peak years. He was forced to sell it in September 1974 for £500 due to financial pressures from his drug addiction. Gibson created a limited edition recreation in 2012 based on analysis of the original instrument.
Did Paul Kossoff use pedals?: Barely. His signal chain was almost exclusively guitar straight into amp. He used a wah pedal on specific tracks (documented from 1969 onward), a Leslie rotary cabinet in studio on certain tracks from 1972, and reportedly an Echoplex delay in some live contexts. No overdrive pedal, no fuzz, no compression — his distortion came entirely from driving Marshall tube amps at high volume.
How did Paul Kossoff get his vibrato?: Kossoff used his index finger as the primary vibrato finger, backed up by the ring finger for additional control and stability — an unorthodox technique he developed himself from his classical guitar foundation. He worked obsessively on developing vibrato speed and consistency, and his fast, controlled technique became his most imitated and least successfully replicated characteristic. He used heavier strings and picks than most contemporaries specifically to build the hand strength required for this approach.
What strings and picks did Paul Kossoff use?: Heavier gauges than most of his contemporaries — consistently reported as .011 or heavier string gauge, and correspondingly heavy picks (1.0mm or thicker). These choices were directly related to his vibrato technique: heavier strings under more tension provide more resistance and produce more sustain when bent, which was fundamental to the tone and feel he was pursuing.
How do I get Paul Kossoff’s guitar tone?: Start with a Les Paul equipped with low-to-medium output PAF-spec humbuckers (Alnico II or III, 7–8.5kΩ). Run it into a Marshall Plexi-circuit amp — Super Bass circuit preferred — with the mids cranked (7–8), treble moderate (5–6), bass tight (3–4), and volume pushed hard enough to drive the power tubes into natural compression. No pedals required. The tone depends primarily on developing a fast, controlled index-finger vibrato — without that technique, no gear combination will get you to the right destination.
