“My go-to rig: I’ve got an SG, for sure… one always has a P-90 in it, and one has a humbucker in it. Then my amp would be my [100-watt EL34-powered] Friedman X signature amp. And the pedal is my J Rockett PXO signature overdrive. So that would be my go-to rig. I have all that stuff when I play with Bon Jovi and with The Drills; it’s my go-to for anything and everything.” Phil X said this to Guitar World in November 2025 — and the statement’s conciseness is the point. An SG. A Friedman. A J Rockett overdrive. One pedal. One amp. One guitar family. For anything and everything. This is the guitar signal chain of a man who has played on hundreds of LA sessions for artists including Kelly Clarkson, Rob Zombie, Alice Cooper, Avril Lavigne, Chris Cornell, Chris Daughtry, Tommy Lee, and Methods of Mayhem — a session guitarist whose specific professional requirement is versatility, and whose specific discovery was that versatility comes from skill and touch rather than from extensive gear. His “penchant for minimal gain on the guitar” and his “aversion to amp modeling” (Gibson Gazette) stand in productive contrast to his enormous reach: the session guitarist who became a YouTube star demonstrating vintage guitars on the Fretted Americana channel, whose performances built the fanbase that led Jon Bon Jovi to call and say “Hey. We need you.” Phil X filled Richie Sambora’s “sizeable snakeskin shoes” (MusicRadar) in 2011 as a substitute, became officially Bon Jovi’s lead guitarist in 2016, and has been there ever since. One SG. One Friedman. One J Rockett. Pow. Right in the kisser.
Theofilos Xenidis — Phil X — was born on March 10, 1966, in Toronto, Ontario, Canada. He formed his first band, Sidinex (his surname spelled backwards), in 1982 at age sixteen — opening local shows for bands like Nazareth and Thor. He relocated to Los Angeles, where he built a prolific session career appearing on recordings by Tommy Lee, Methods of Mayhem, Avril Lavigne, Kelly Clarkson, Orianthi, Rob Zombie, Chris Daughtry, Alice Cooper, Thousand Foot Krutch, Chris Cornell, Taylor Hawkins (pre-Foo Fighters), and dozens of other artists. His breakthrough outside the session world came through the Fretted Americana YouTube channel, where he hosted vintage guitar demonstration videos — combining his technical guitar demonstrations with his large-scale personality and humor in a format that generated millions of views and built an international fanbase. Jon Bon Jovi called in 2011 when Richie Sambora needed a temporary replacement; Phil X delivered. He has been delivering ever since. He is sixty years old. He is still Bon Jovi’s guitarist. The SG is still his go-to.
Background: Toronto Canada, Los Angeles Session World, Fretted Americana YouTube, “Jon Bon Jovi Called and Said ‘Hey. We Need You.'”
Phil X’s career trajectory is the most specifically modern in this section of the guide — a musician who built a professional profile through conventional session work (playing on other people’s records in Los Angeles, accumulating credits without front-person visibility) and then built a public profile through YouTube (demonstrating vintage guitars with charisma and technical ability in a format that the internet enabled and that television could not have produced). The combination of the two — session credentials establishing the musical quality, YouTube establishing the personality — produced the specific kind of visibility that resulted in Jon Bon Jovi calling. He would not have gotten the call without the session credentials; he would not have been easily found without the YouTube presence. Both were necessary.
His role in replacing Richie Sambora — one of the most recognizable rock guitarists of the 1980s and 1990s, whose specific combination of slide guitar fluency, whammy bar theatrics, and melodic pop-rock sensibility defined Bon Jovi’s guitar sound across their commercial peak — required both technical ability (to replicate Sambora’s parts accurately) and personality (to bring sufficient stage presence to a band whose visual identity is as important as their musical one). Phil X provided both: the MusicRadar characterization of him filling “Sambora’s sizeable snakeskin shoes” reflects both the difficulty of the role and his success in filling it. The snakeskin shoes fit. The gig became permanent.
His “aversion to amp modeling” — documented in the Gibson Gazette interview — is the most specifically old-school position among the younger guitarists in this guide. Where guitarists like Bill Kelliher (Series 2 #186) have settled on Helix, and Ihsahn (Series 2 #169) uses Neural DSP, and Jari Mäenpää (Series 2 #179) uses both Fractal Axe-FX and Neural DSP, Phil X maintains his preference for real tube amplifiers (specifically his Friedman signature). His “penchant for minimal gain” — less gain than most rock guitarists would use, trusting the pickup’s and the amp’s natural interaction to provide the tone — reflects a philosophy similar to Wino Weinrich’s (Series 2 #182) “guitar into amp” approach: the guitar’s natural character and the amp’s natural response are the tone, not the gain control.
The Rig: Phil X’s Guitars, Amps, and Effects
Guitars
Gibson Phil X SG Prototype and Production (Current Primary Guitar, P-90 and Humbucker Versions): Phil X’s current primary guitar family is the Gibson SG — specifically his signature Gibson Phil X SG. The Guitar World November 2025 interview confirms: “I’ve got an SG, for sure, especially that prototype that I was talking about. But I have another two SGs — one always has a P-90 in it, and one has a humbucker in it.” The Equipboard documentation: “At the 2020 NAMM show, Phil X was associated with the Gibson Phil X SG, as reported by Guitar World.” His SG with P-90 — the single-coil soap-bar pickup in a humbucker-sized body — provides a specific bright, aggressive, “barky” single-coil character that differs from standard SG humbuckers, while the SG with humbucker provides the warmer, more rounded character of traditional British humbucker tone. Using two SG variants (P-90 and humbucker) within the same basic instrument family provides tonal variety without the instrument-switching that different body types would require.
The P-90 preference aligns with his “minimal gain” philosophy: P-90 pickups have a specific midrange-forward, somewhat compressed character that suits lower-gain amplifier settings — the P-90 into a clean-to-moderate-gain amp produces a specific cutting, present tone that humbucker-into-high-gain configurations don’t have. His Arcane PX90 signature pickup (an earlier collaboration with pickup maker Arcane) documented in Rock Guitar Universe — “Phil X was using a single Arcane PX90 pickup in the bridge position” — reflects this P-90 preference across different guitar periods.
Yamaha SG1801PX (Phil X Signature, “Les Paul Killer”): Before his Gibson endorsement, Phil X’s signature production guitar was the Yamaha SG1801PX — his collaboration with Yamaha. The Rock Guitar Universe documentation: “This model was also called Phil X’s signature model, as Yamaha designed it for Phil X. It is also called ‘Les Paul Killer’ with its excellent design and sound.” The Yamaha SG series has historically been one of the most respected production guitars for quality-to-price ratio — Tony Iommi used Yamaha SG2000s for a period, and the SG series’ construction quality (mahogany body, mahogany neck, carved maple top on some models) made it a working musician’s alternative to the Les Paul. “Les Paul Killer” is a characterization the Yamaha SG community has embraced for decades, and Phil X’s endorsement of it validates the approach.
ESP LTD Viper (Session Work and Touring, “His Most Loved Guitar”): The Rock Guitar Universe documentation identifies the ESP LTD Viper as “his most loved guitar” — a single-pickup ESP LTD instrument tuned to Drop C, used specifically for “We Got It Going On” with Bon Jovi. “He says the guitar sounds enormous when you go for those low notes. It again only has a single humbucker in the bridge position.” The single-humbucker Drop-C Viper is the specific tool for the heaviest material in the Bon Jovi live set — a guitar optimized for maximum low-frequency authority and maximum gain simplicity (single humbucker eliminates pickup switching decisions).
Gibson Explorer (NAMM Demonstration and Session): The Gibson Gazette interview features Phil X with a Gibson Explorer — demonstrating chromatic and pentatonic scale applications and discussing guitar technique. The Explorer’s history with technical guitarists (Kelliher’s “Golden Axe” Explorer, Series 2 #186; Vinnie Vincent’s preference for V-shaped instruments, Series 2 #189) makes it a natural demonstration instrument for a guitarist discussing technique.
Single-Pickup Preference (“Phil X is Known for His Love for Collecting Guitars Along with His Preference for Single-Pickup Guitars”): The Rock Guitar Universe characterization of his gear philosophy — “known for his love for collecting guitars and equipment, along with his preference for single-pickup guitars” — reflects the specific tonal approach of a guitarist who values simplicity and directness over tonal variety in a single instrument. A single pickup (especially a single P-90 or single humbucker) eliminates the pickup-switching decisions that multi-pickup guitars require and focuses the tonal identity of the instrument on a single pickup’s specific character. This is consistent with his minimal gain philosophy: reduce complexity, trust the instrument and amp’s natural interaction, play.
Amps
Friedman Phil X Signature Amplifier (100W EL34, “My Amp”): Phil X’s primary amplifier is the Friedman Phil X signature — “my [100-watt EL34-powered] Friedman X signature amp” (Guitar World 2025). Friedman Amplification — the same boutique amp builder who developed the Butterslax for Bill Kelliher (Series 2 #186) and who is associated with the specific warm, harmonically complex high-gain character of hand-wired British-influenced tube amplifiers — produced the Phil X signature with EL34 power tubes. EL34 tubes (the British tube type, as opposed to the American 6L6 and 6V6) provide the specific warm, somewhat compressed, harmonically rich power tube character associated with vintage Marshalls. Combined with his “minimal gain” philosophy — trusting the EL34’s natural saturation rather than pre-amp-stage high gain — the Friedman Phil X head produces the specific “dirty but girthy rock tones” that MusicRadar identifies as his sonic target. The Equipboard documentation also confirms: “I’m plugged into the Friedman Brown Eye, which is a kick-ass high-powered amp” — the Friedman Brown Eye being a different Friedman model also in his collection.
Friedman Cabinets and Marshall 1960A 4×12 (Speaker Cabinets): The Rock Guitar Universe documentation confirms: “The Friedman amp heads of Phil X are connected to Friedman 4×12 cabinets. With most of his amp heads, Phil X uses Marshall 4×12 Cabinets. Although there are many different models, such as 1975, 1957, and more, he uses the 1960A model the most.” Both Friedman 4×12 cabinets and Marshall 1960A 4×12 cabinets appear in his documented speaker configuration — the combination providing the professional-level speaker coverage appropriate for arena touring with Bon Jovi.
Kasha Amplifiers (“Evil Robot by Tone Americana, Kasha Amplifiers and Phil X”): The Equipboard documentation references Kasha Amplifiers as part of his collection — the “Evil Robot by Tone Americana” appearing in the documented Fretted Americana YouTube context. The Kasha amps reflect his history with boutique amplifier exploration before and alongside the Friedman relationship.
“Aversion to Amp Modeling” (Gibson Gazette 2024): The Gibson Gazette interview documents his specific anti-modeling position — “his aversion to amp modeling” alongside his “penchant for minimal gain on the guitar.” Where the modern guitar world has largely accepted digital modeling (Fractal Axe-FX, Line 6 Helix, Neural DSP, Kemper) as valid and increasingly ubiquitous, Phil X maintains his preference for real tube amplifiers. The philosophical position: real tube amplifiers respond differently to picking dynamics, string attack, and guitar volume control than digital models, and this dynamic responsiveness is an important musical dimension of the guitar experience that modeling approximates but doesn’t fully replicate.
Effects
J Rockett PXO Signature Overdrive (Primary and Go-To Pedal): The single most important pedal in Phil X’s signal chain is the J Rockett PXO — his own signature overdrive produced in collaboration with J Rockett Audio Designs. Guitar World 2025: “The pedal is my J Rockett PXO signature overdrive. So that would be my go-to rig… it’s my go-to for anything and everything.” J Rockett Audio Designs is a boutique pedal company known for their high-quality, musically voiced overdrive and distortion pedals. The PXO (Phil X Overdrive) represents his specific overdrive character — consistent with his minimal gain philosophy, it provides the specific transparent boost-to-overdrive character that enhances the Friedman’s natural tube saturation without dramatically changing its tonal character.
“Fuck Jazz” Overdrive by LAA Custom (Stage Board Prototype Drive): The MusicRadar interview documents one of the more specifically named pedals in this guide: “Phil’s stage ‘board has a couple of prototype drives on it, including the bracingly titled ‘Fuck Jazz’ overdrive by LAA Custom.” The LAA Custom “Fuck Jazz” prototype — a boutique overdrive whose naming reflects either a specific tonal character or Phil X’s sense of humor (probably both) — represents the experimental, prototype-driven dimension of his effects exploration that coexists with the more committed J Rockett PXO primary pedal approach.
Radial Tonebone Twin City Pedal (A/B Switch, Instagram Confirmed): “You can see the Tonebone Bones Twin-City Pedal on a picture Phil X posted of his pedalboard on Instagram.” The Radial Tonebone Twin-City — an A/B amplifier switcher that allows routing between two amplifiers — documents his two-amp approach: switching between the Friedman head and a secondary amplifier for tonal variety within the Bon Jovi live set.
Bouzouki Tuning (Specific Application, Gibson Gazette): The Gibson Gazette interview title — “Phil X on Bon Jovi, bouzouki tuning & what it takes to be great on guitar” — references his exploration of bouzouki tuning for specific guitar applications. The bouzouki is a Greek stringed instrument (appropriate given his Greek-Canadian heritage) tuned in courses (pairs of strings), and applying bouzouki tuning concepts to guitar produces specific harmonic and melodic approaches not available in standard tuning. His exploration of this non-standard tuning reflects the same curiosity about sonic possibility that characterized his vintage guitar demonstrations on Fretted Americana.
Playing Style & Tone Philosophy
Phil X’s playing style is the most professionally versatile in this section of the guide — the approach of a musician who has spent his career developing the technical range to play any style of rock guitar required by any session client, any touring situation, or any musical context. His specific description of his goals: “dirty but girthy rock tones by careful EQ and gain tweaking.” The combination of “dirty” (enough saturation for rock energy) with “girthy” (full, warm, three-dimensional tone rather than thin or compressed) describes his specific tonal target — the classic rock guitar sound of the 1970s and 1980s albums that defined the genre’s sonic possibilities.
His “minimal gain” philosophy is the specific tonal approach that contradicts the conventional metal/hard rock assumption that more gain equals better. More gain compresses the guitar’s dynamic range, blurs the attack of individual notes, and creates a “wall of sound” effect that can be physically overwhelming but musically limiting. Minimal gain allows the guitar’s natural picking dynamics, string attack, and volume control to produce tonal variation — the pickup’s and amp’s natural interaction providing the harmonic richness that maximum gain achieves through sheer saturation. His specific “minimal gain into a good tube amp” approach produces the specific touch-responsive, dynamically alive quality of classic rock guitar.
His YouTube-first approach to building an audience — demonstrating vintage guitars with personality and technical skill rather than releasing his own recordings — is the most specifically 21st-century career-building strategy in this guide. The session world (commercial, credit-sparse, invisible to the public) combined with the YouTube platform (highly visible, personality-forward, direct to audience) produced a specific kind of public profile that led directly to the Bon Jovi call. He is the template for the 21st-century working guitarist who builds a career through both session craft and online personality simultaneously.
How to Sound Like Phil X
Guitar: Gibson SG with P-90 in the bridge position — the specific “barky,” midrange-forward, aggressive single-coil character of the P-90 through a moderate-gain amp is the Phil X Bon Jovi tone. Alternatively, SG with standard humbucker for warmer, more traditional hard rock. Single-pickup configuration preferred — eliminates decision complexity, focuses tonal identity.
Amp: Friedman Phil X signature (or comparable Friedman model) — 100 watts, EL34 power tubes. Set the gain lower than feels natural for rock guitar: trust the EL34’s natural saturation rather than pre-amp gain for the distortion character.
Amp Settings (Friedman Phil X — “Dirty but Girthy” at Minimal Gain):
| Control | Setting (0–10) | Notes |
|---|---|---|
| Gain | 4–6 | MINIMAL — lower than expected. Trust the EL34’s natural saturation |
| Bass | 5–6 | “Girthy” — full, warm low-end for the three-dimensional rock tone |
| Mid | 6 | Forward — the P-90’s natural mid character needs mid support |
| Treble | 5–6 | Present but warm — not excessively bright at minimal gain |
| Presence | 5 | Moderate — attack definition for the P-90’s natural attack character |
Overdrive: J Rockett PXO (or comparable transparent boutique overdrive — Klon-style, low gain, volume boost with minimal coloration). Set gain low on the overdrive — the overdrive boosts the amp’s input, allowing the amp to produce natural tube saturation. Don’t add overdrive distortion character on top of amp distortion; use the overdrive to push the amp. The “Fuck Jazz” prototype from LAA Custom documents the experimental dimension of his effects exploration — try different boutique drives to find the specific boost character that complements the Friedman’s natural response.
Influence & Legacy
Phil X’s influence is the most specifically contemporary in this section of the guide — a working musician whose specific approach to career building (session craft + online presence = major band gig) represents a new template for how guitarists of exceptional technical ability can build professional visibility in the digital age. His decades of session work for the full range of commercial popular music (Kelly Clarkson to Rob Zombie, Alice Cooper to Chris Daughtry) document the specific breadth of technical range that his minimal-gain, P-90 SG approach can accommodate.
His connection to Vinnie Vincent (Series 2 #189) as a fellow guitarist who replaced a predecessor in an established band reflects the specific career context of the “hired gun” who becomes permanent — different predecessor quality levels (Sambora was celebrated, Frehley was beloved) but the same fundamental situation: demonstrating that the show goes on with a different guitarist. His connection to Rick Springfield (Series 2 #191) as a fellow musician in the pop-rock tradition that Bon Jovi occupies reflects the shared commercial context.

Frequently Asked Questions: Phil X Bon Jovi Guitars & Gear
What guitar does Phil X play?
Phil X’s current primary guitar is the Gibson Phil X SG signature — he uses two versions, one with a P-90 pickup and one with a humbucker. “I’ve got an SG, for sure, especially that prototype that I was talking about. But I have another two SGs — one always has a P-90 in it, and one has a humbucker in it.” Previous signature guitar: Yamaha SG1801PX (“Les Paul Killer”). Also uses ESP LTD Viper (single humbucker, Drop C, for “We Got It Going On”) and Gibson Explorer (demonstrations). He is known for preferring single-pickup guitars and is a Gibson-endorsed artist.
What amplifier does Phil X use?
Phil X’s primary amplifier is the Friedman Phil X signature — “my [100-watt EL34-powered] Friedman X signature amp.” He runs it through both Friedman 4×12 cabinets and Marshall 1960A 4×12 cabinets. He has an “aversion to amp modeling” and a “penchant for minimal gain on the guitar” — preferring real EL34 tube amplifiers at lower-than-usual gain settings to produce “dirty but girthy rock tones.” He also uses the Friedman Brown Eye in his collection.
What overdrive pedal does Phil X use?
Phil X’s primary and go-to overdrive pedal is the J Rockett PXO — his own signature overdrive produced in collaboration with J Rockett Audio Designs. “The pedal is my J Rockett PXO signature overdrive. So that would be my go-to rig… it’s my go-to for anything and everything.” His stage pedalboard also features prototype drives including the “Fuck Jazz” overdrive by LAA Custom, and he uses a Radial Tonebone Twin-City A/B switcher for routing between amplifiers.
How did Phil X get the Bon Jovi gig?
Phil X began his Bon Jovi association in 2011 as a substitute guitarist when Richie Sambora needed to miss shows for personal reasons. “Jon Bon Jovi called, and he said, ‘Hey. We need you.'” His visibility at the time came both from his extensive LA session credentials (hundreds of recordings across multiple genres) and from his YouTube presence on the Fretted Americana channel, where he demonstrated vintage guitars with charisma and technical skill. He became an official band member in 2016, replacing Sambora permanently.
What is Phil X’s “minimal gain” philosophy?
Phil X has a “penchant for minimal gain on the guitar” — setting his amplifier gain lower than most rock guitarists would expect, trusting the natural interaction between the guitar pickup and the EL34 power tubes to produce the saturation and harmonic richness he needs. The goal is “dirty but girthy rock tones by careful EQ and gain tweaking” — enough saturation for rock energy (“dirty”) with full, warm, three-dimensional tone (“girthy”). Excessive gain compresses the guitar’s dynamic range and blurs the attack; minimal gain preserves the picking dynamics and string attack that give his playing its specific live quality.
What is the Fretted Americana YouTube connection?
Before the Bon Jovi gig, Phil X hosted a vintage guitar demonstration series for the Fretted Americana vintage guitar shop on YouTube. The format — demonstrating vintage guitars with technical skill, charisma, and humor — generated millions of views and built a large international fanbase. “His flamboyant online riffage would win him one of the biggest gigs in rock.” His public visibility from YouTube made it easy for Jon Bon Jovi’s people to find him as a potential Sambora substitute; without both the session credentials (establishing musical quality) and the YouTube presence (establishing public personality), the Bon Jovi call may not have come.
What session work has Phil X done before Bon Jovi?
Phil X built an extensive LA session career before joining Bon Jovi, recording with Tommy Lee and Methods of Mayhem, Avril Lavigne, Kelly Clarkson, Orianthi, Rob Zombie, Chris Daughtry, Alice Cooper, Thousand Foot Krutch, Chris Cornell, Taylor Hawkins, and many others. He has also been a member of Triumph (the Canadian rock band), co-founded the band Powder (2001), and performed in various other projects. His session experience spans the full range of commercial rock genres from hard rock to pop, giving him the specific versatility that the Bon Jovi role — covering Richie Sambora’s diverse contributions to a long catalog — required.
