Carvin Legacy II - Clean preset

Close · 70/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Legacy II is the second version of Carvin's Steve Vai signature head: 100 watts from four EL34s (with a bias switch for 6L6GC/5881), with a 100/50/25 W power switch. Three footswitchable channels, Clean, Lead and Boost, are relay-switched, each with its own volume and presence control. An effects loop, master, a 12AX7 long-tail phase inverter, 12 dB of negative feedback and a cabinet-voiced line out complete it.

Schematic-derived preset files for the Neural DSP Quad Cortex and 16 Fractal and Line 6 modelers: Axe-Fx II/XL/XL+, Axe-Fx III, FM3, FM9, and the full Helix family (Floor, LT, Rack, HX Stomp, HX Stomp XL, Native).

Gridleak extracts amp parameters from original circuit schematics using AI vision — component values, gain staging, tone stack topology, tube types — then generates native preset files for every supported modeler. Every extraction is scored 0–100 and the score is published.
