Unknown Gilmore Jr. preset

Verified · 89/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Gilmore Jr. is a tiny DIY valve amp design from 2010. A single input feeds a 12AX7 gain stage, a tone control and a volume, then the second 12AX7 half. The output stage is unusual: the two triodes of a 6N1P run as a cathode-coupled push-pull pair into a small output transformer, with no negative feedback. The supply uses a two-diode full-wave rectifier with a standby switch; an ECC99, 12AU7 or 12AT7 can replace the 6N1P.

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.
