Fender 140 - Lead preset

Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Fender 140 is the largest of Fender's early-1980s 30/75/140 tube series, a 140-watt lead amp with reverb. One preamp has treble, bass and middle with boost switches, a bright switch and a volume, and a footswitchable lead circuit adds a 7025 stage with its own drive and lead master. A five-band graphic EQ, effects loop and spring reverb follow, and a 12AT7 inverter drives four 6L6GCs with a high/low power switch.

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.
