Provenance up front: Lynch is a *documented Jose customer* — Bryan Jay of Keel placed Lynch among the guitarists whose Marshalls were sitting in Jose's garage being worked on (per the Reverb News piece on the early high-gain modders). But the documented Back for the Attack-era recording rig is Lee Jackson Metaltronix-modded Plexis (1968-chassis donors, re-tubed with 6550 power tubes), with Aspen Pittman's purple Plexi also in the studio. So Jose-modded amps existed in Lynch's collection, but the specific BFTA recorded tones (e.g. "Mr. Scary") are most reliably attributed to the Lee Jackson rig, not to Jose mods. Lynch's amps were also worked on by Tim Caswell post-S.I.R., so the modder lineage on his Marshalls is genuinely multi-builder rather than a clean single-modder story.
Why this matters for the JMIL framing: the previous version of this entry attributed "Mr. Scary" lead forensics (compressed sustain, soft pick attack) specifically to diode clipping as if confirming a Jose recipe. That's not supported once the Lee Jackson Metaltronix rig is in the picture — the Metaltronix preamp circuit is its own design and has its own clipping character that overlaps with the Jose family of tones without being the same circuit. Treat BFTA-era recordings as "Lee Jackson-modded Plexi territory, family-resembling the Jose canon but not a Jose-mod forensics case study."
Where the Jose family-resemblance recipe still applies: Lynch's broader career rhythm and lead tones do live in the same neighborhood as the canonical Jose-2203 recipe — cascaded gain, master-volume control over the gain-stage feel, channel-jumper-style upper-mid weight, and harmonic sustain. So the JMIL surface area below is best understood as "an approximation of the Lynch tonal *family*, not a forensics reconstruction of any specific recording."
Pickup pairing nuance: Lynch's signature Seymour Duncan Screamin' Demon is a moderate-output bridge humbucker (~14k DC). It pairs with cascaded-gain Marshall-family preamps better than a hot ceramic would — the gain headroom from the cascade plus moderate input level keeps the tone articulate rather than mush. JMIL's audio engine doesn't model pickup output level, but the canon pairing is "moderate-output PAF-style + lots of preamp gain", not "ceramic monster + clean-ish amp".
JMIL surface area (for the broader Lynch tonal family, not a BFTA forensic reconstruction): start from the Stock 2203 chassis, enable Jose Master Volume + cascade, optionally add channel jumper. Dial the Mid knob ~7/10 (Lynch ran mids high) and Presence ~6/10. The "Brown Sound" preset is too tight and too compressed for Lynch — it's voiced for EVH's amps.
Rig detail beyond the amp (Friedman, Amp Panel #9 [106:21]): Lynch used a Hiwatt cabinet with cast-frame fans loaded alongside his Plexi for many years, and ran a GE-10 graphic EQ in front of the Plexi. Friedman: *"I can't even begin to explain how epic it sounded."* The Hiwatt-loaded cab + GE-10-pre-amp combo is distinct from canonical Jose-school rigs (which typically use Marshall/Celestion-loaded cabs straight in) and contributes to Lynch's specific midrange-forward, semi-pre-shaped tone that's hard to recreate with a Marshall-and-cable-only rig.
Adjacency to Faulkner (see richie-faulkner-jose): Richie Faulkner's three Friedman amps share design DNA with Lynch's signature Friedman amp — Faulkner's amp was the inspiration for the Lynch model per Friedman ([Panel #5 44:44]). Both are early-80s 2203 donor chassis, both are "optimized 2203" builds (no V0 cascade, no diodes, focused on getting the canonical 2203 voicing to its peak), and the same JMIL settings approximate both.
