Epiphone EA-101 preset

Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Epiphone 101 (TUL-4032) is a small Kalamazoo-built student amp. Two inputs feed one half of a 12AX7A, a tone control and a volume, and the other half drives a single 6BQ5 (EL84) running single-ended and cathode-biased into the speaker. A second 12AX7A is a phase-shift tremolo oscillator with a frequency control that switches it off, and a 6X4 valve rectifier supplies the amp. It breaks up easily at low volume.

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.
