Garnet G15T Gnome preset

Verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The G15T Gnome is a small single-channel Garnet combo from Winnipeg. Two inputs feed a 12AX7 stage, treble and bass controls and a volume, then a second 12AX7 stage drives a single cathode-biased output valve: a 6L6GC on the 1979 factory sheet, a 6V6GT in a later example. Tremolo comes from a 12AX7 phase-shift oscillator with speed and depth and a footswitch, not a FET, and the supply uses silicon diodes.

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.
