Peak Composer - Lead preset

Verified · 82/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Peak Composer is a 1981 tube amp system made up of a two-channel preamp, a 5-band EQ and a power amp. The preamp uses two 7025s and a JFET, with gain boost, master, and separate lead drive and lead volume controls. The power amp uses an ECC83 phase inverter and four 6L6GCs, switchable between 60 and 100 W.

• Wattage: 100W
• Channels: 2
• Preamp tubes: 2× 7025, 1× ECC83
• Power tubes: 4× 6L6GC

Tags: 6l6, high-wattage, two-channel, crunch.

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.
