Earth Sound Research Revival preset

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

A hybrid amp from Earth Sound Research's Revival series. A transistor/JFET preamp with volume, treble, bass, middle and master drives four 6L6s through a transformer-coupled output, with a delay-line reverb. Bright and normal inputs feed one channel, and the series also came in 60-watt and bass versions.

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.
