Epiphone EA-22RVT Mighty Mite preset

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

The EA-22RVT Mighty Mite is a 1960s Epiphone tube combo with spring reverb and tremolo. Its Bright, Stereo and Mello inputs are voiced differently but all feed one preamp with a single set of bass, treble and loudness controls. 12AY7s handle the preamp and reverb driver, 6EU7 twin triodes the reverb recovery, phase inverter and tremolo (speed and depth), and a pair of EL34s in push-pull run from a silicon diode rectifier with a filter choke.

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.
