Fender Harvard Reverb preset

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

The Harvard Reverb is an early-1980s solid-state Fender combo that reuses the old valve Harvard name. It has a single channel: two inputs feed three JFET gain stages with Treble, Bass, Volume and a Master Volume. An op-amp and transistor driver run the spring reverb, with a Reverb control and footswitch, and a discrete transistor power amp has a power-boost switch, headphone and line outs.

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.
