Peavey Ultra Plus - Clean preset

Verified · 89/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Peavey Ultra Plus is a 120-watt, three-channel all-tube head (1996-97). Two inputs feed a 12AX7 stage, then a Clean channel with its own pre gain, High, Mid and Low and bright/deep switches, and relay-switched Crunch and Ultra channels with diode clipping, separate pre and post gains and shared Bottom, Body and Edge voicing. Op-amp spring reverb, an effects loop and a 12AX7 inverter with presence and resonance drive four fixed-bias 6L6GCs.

Schematic-derived preset files for 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.
