Guild 100-J - Accordion preset

Verified · 87/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The 100-J is a mid-1960s Guild combo in green tolex with Accordion and Guitar channels, two inputs each (Bright and Normal on Guitar), each on its own 12AX7 triode with its own volume, mixed into shared bass and treble controls. Two 12AX7s with paralleled sections form the phase inverter, and a third 12AX7 runs a tremolo with speed and depth. A cathode-biased push-pull pair of 6L6s on a 5U4 rectifier drives a 15-inch Jensen speaker.

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.
