Ronnie Montrose Guitars & Gear: The Complete Guide to America’s Hard Rock Pioneer’s Rig

Ronnie Montrose’s primary guitar during the Montrose band period — the recordings and performances that defined his signature sound — was a sunburst Gibson Les Paul Standard. The Dinosaur Rock Guitar documentation establishes this clearly: “Early on, Ronnie’s tone in the band Montrose was usually an overdriven Les Paul tone (though there’s some Strat too). For the first years of his career, Ronnie was associated with a sunburst Les Paul (shown top).” The sunburst Les Paul Standard’s specific character — the mahogany body and neck with maple cap, the PAF-style or PAF-replica humbuckers of the early 1970s vintage, the 24.75-inch Gibson scale — produces the specific “beefier than Page’s tone and had more bite than Scott Gorham’s tone” quality that Dinosaur Rock Guitar identifies as the distinguishing characteristic of Montrose’s Les Paul sound. The distinction between “beefier than Page” and “more bite than Gorham” captures the specific tonal position he occupied: heavier than Led Zeppelin’s more blues-oriented approach, more aggressive than Thin Lizzy’s more melodic dual-guitar approach.

The Vintage Guitar magazine documentation provides specific dates for his relationship with a vintage Les Paul: “A 1958 Les Paul Standard. He purchased it in 1977, and retired it after seven years.” The 1958 Les Paul Standard is one of the most historically significant electric guitars in rock — the original “Sunburst” Les Paul of the “Burst” era (1958-1960) that has been the most sought-after electric guitar in the vintage market since their specific tonal qualities were recognized in the late 1960s. Montrose’s seven-year relationship with this instrument (1977-1984) spans his solo recording period and the Gamma band years — the specific transition from the raw Montrose hard rock to the more sophisticated, electronica-influenced direction of his later work. That he eventually “retired” it — set it aside rather than sold it — reflects a specific protective relationship to a historically significant instrument.

The Montrose Equipboard band page confirms the Fender Stratocaster alongside the Les Paul: “Ronnie Montrose’s use of the Fender Stratocaster Electric Guitar, combined with the searing tones of the Electro-Harmonix Big Muff Pi fuzz pedal, produced a distinct” character on the Montrose recordings. The Strat is documented specifically for “Bad Motor Scooter,” “Make It Last,” and “Rock Candy” on the debut album. The Strat’s specific character — brighter, twangier, with the single-coil’s characteristic clarity and pick attack — provides tonal variety from the Les Paul’s warmer humbucker approach and suits certain specific tracks better than the heavier Les Paul character.

The most specifically documented instrument in Montrose’s career history is the Fender Esquire used for the Open Fire album (1978) — because he sold it to Carlos Santana immediately afterward. The International Musician and Recording World quote: “On my solo LP I just used a little amp and a fuzz (tone). The main instrument I used was a Fender Esquire that I just sold to Carlos Santana.” The Fender Esquire is the single-pickup version of the Telecaster — one pickup (bridge), no pickup selector, simplified control layout — and its specific character (the Telecaster bridge pickup’s aggressive, focused attack) suited the specific demands of the Open Fire instrumental album. That he subsequently sold it to Santana — arguably the most celebrated guitarist in San Francisco music history at that time — and mentioned it so casually (“I just sold to Carlos Santana”) reflects the “not into flash” philosophy applied to instrument ownership: good guitars are for playing, not for preserving.

The Equipboard documentation describes his primary acoustic guitar: “Ronnie Montrose’s main performance acoustic guitar, a 2003 Taylor 712-CE flattop cutaway. It has a natural finish, Sunrise pickup, added input jack, an extra strap button hole, and no truss rod cover.” The Taylor 712-CE — a Grand Concert cutaway acoustic with electronics — represents the acoustic dimension of his career that existed alongside his electric work. The Sunrise magnetic pickup and the added input jack reflect the professional acoustic-electric performance requirements for live acoustic playing.

The Gemtracks documentation references “the Ronnie Montrose 1943 Gibson J-45 ‘The Old Boy'” — a wartime-era Gibson acoustic with the specific character of pre-war construction and aged tonewoods. The J-45 is a dreadnought acoustic associated with the folk and country-folk tradition; a 1943 example represents the earliest period of J-45 production, with the specific tonal character of 80-plus-year-old tonewoods.

The Dinosaur Rock Guitar documentation is specific: “A rare live photo of Hagar-era Montrose shows Ronnie him in front Ampeg V4 stacks (7027A tubes).” The Ampeg V4 — a 100-watt all-tube head using 7027A power tubes (a specific tube type rather than the more common 6L6 or EL34) — provides the specific American amplifier character that gives the Montrose recordings their particular quality. The 7027A is a tetrode power tube with a specific warm, powerful, slightly compressed character — different from the EL34’s British warmth and from the 6L6’s American clarity. The V4’s specific sound, combined with the Les Paul’s PAF humbuckers, produces the “beefier than Page, more bite than Gorham” quality that defines the Montrose hard rock tone.

The Circus magazine 1982 Equipboard documentation provides his studio amp preference: “Ronnie’s chosen amp for the past three years has been an old single cabinet tweed Fender Bandmaster with three 10′ speakers.” The Fender Tweed Bandmaster — a late-1950s/early-1960s Fender tube combo with three 10-inch speakers — is a dramatically different amplifier choice from the Ampeg V4 stacks. The Bandmaster’s specific character: the warm, relatively clean American tube response of the late-1950s Fender tweed series, with natural breakup at moderate volumes. Its three 10-inch speakers provide a specific midrange-forward response different from 12-inch speakers. “He has used the Marshalls on a few tracks, but their volume makes them difficult to work with when other band members are recording in the same room” — the Bandmaster’s lower volume ceiling makes it more practical for studio recording where volume needs to be controlled.

The Equipboard Open Fire album documentation: “In a vintage promotional advertisement for the album ‘Open Fire,’ guitarist Ronnie Montrose is depicted using the Lab Series L5 guitar amplifier.” The Lab Series (produced by Music Man, later Gibson) were transistor hybrid amplifiers — combining solid-state power sections with some tube elements — known for their specific clean, precise, professional character. The Lab Series L11 (also documented in the Gemtracks profile) is the higher-powered version. Their use for the Open Fire era reflects his ongoing exploration of different amplification approaches as he moved beyond straightforward hard rock toward more experimental instrumental territory.

The Fretlounge documentation confirms Marshall JMP use alongside his other amplifiers: “His aggressive hard rock tone was largely achieved using Marshall amplifiers, specifically a Marshall JMP head, often paired with Fender amps for clean tones and added dimension.” The Marshall JMP’s specific character — British EL34-powered tube saturation — provides a different harmonic character from the Ampeg V4’s 7027A American tone. The pairing of Marshall for driven tones and Fender for clean tones is the specific multi-amp approach that gives the best recorded hard rock tones their dimensional, layered character.

The Equipboard auction documentation confirms: “Ronnie Montrose’s Mesa Boogie 20/20 DynaWatt EL84 all tube stereo power amp with a black nylon case.” The Mesa Boogie 20/20 — a stereo power amplifier using EL84 tubes (the smaller British tube associated with Vox amplifiers) — reflects his later-career exploration of different power amplifier characters. EL84 tubes produce a specific harmonic richness and saturation character that differs from the 6L6 and EL34 of conventional rock amplification.

Ronnie Montrose’s primary studio effect is the Electro-Harmonix Big Muff Pi fuzz — documented in the 1982 Circus magazine quote: “The stage is free of pedals because, the artist maintains, they always ‘screw up,’ but in the studio he does use a Big Muff fuzztone and an Ampeg Scrambler (the former built into a heavy-duty box).” The specific detail — the Big Muff built into a heavy-duty box rather than in its stock Electro-Harmonix housing — reflects the professional working guitarist’s practical modification: the stock EHX housing is not road-rugged, and a guitarist who doesn’t trust pedals on stage needs the studio fuzz to be reliable when he does use it. The Equipboard documentation adds a specific historical note: “The ‘Triangle’ Big Muff was phased out for the ‘Ram’s Head’ in 1973, the year that Montrose was recorded, ambiguating the version used” — whether the debut album used the Triangle or Ram’s Head circuit variant is historically uncertain, but both belong to the early-1970s Big Muff lineage.

The Circus 1982 documentation confirms the Ampeg Scrambler alongside the Big Muff: “he does use a Big Muff fuzztone and an Ampeg Scrambler.” The Ampeg Scrambler is a specific transistor-based fuzz/overdrive circuit from Ampeg’s effects line — known for its aggressive, biting, somewhat asymmetric clipping character that differs from the Big Muff’s more sustaining, violin-like fuzz. Using both simultaneously or switchably provides two distinct fuzz characters for different recording applications.

The Circus 1982 quote captures Montrose’s live effects philosophy completely: “The stage is free of pedals because, the artist maintains, they always ‘screw up.'” This is the working professional’s rejection of effects pedals for live performance — not a philosophical anti-effects position (he uses them in the studio) but a practical reliability assessment. Effects pedals fail at inopportune moments. A guitarist who has experienced a pedal failure mid-performance understands the appeal of running guitar directly into amplifier where the only failure points are the guitar, the cable, and the amp. His live tone came from the guitar-into-Ampeg-V4 interaction at high power, not from pedal processing.

The Equipboard auction documentation notes “two Bogner RM pedals” in the collection of electronics he built or modified — Bogner’s RM (Rack Module) pedal line providing high-quality preamp tones in pedal format. Their presence in his late-career collection documents his ongoing experimentation with different tone-shaping tools even as his primary live approach remained pedal-free.

The most important “effect” in Ronnie Montrose’s live playing was not a pedal but a technique: “Many of the signature riffs heard throughout his career are made of power dyads which he bent and vibrated with fingers not a whammy bar.” A power dyad is a two-note chord — typically a root and a fifth, or root and a fourth — played simultaneously and bent/vibrated as a unit. The specific physical technique of bending both strings simultaneously with the fretting fingers, maintaining the interval relationship while changing the pitch, produces a specific sound that a whammy bar (which changes all strings’ pitch uniformly) cannot replicate. This is the specific technique that gives Montrose’s riffs their characteristic wide, powerful, slightly unpredictable character: the human hand’s specific pressure and release produces a vibrato that is subtly, musically inconsistent in the most expressive possible way.
