Garnet LB190D Pro preset

Verified · 83/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The LB190D Pro is a Garnet valve head from Winnipeg. Lo and Hi inputs feed a 12AX7 stage, bass, treble and volume controls with switched bright and voicing options, and a second 12AX7 stage. The pentode half of a 6JW8 is the footswitchable Stinger fuzz with fuzz level and colour controls; the triode half is a tremolo oscillator with speed and depth. A 12AX7/7025 cathode-coupled phase splitter drives two 6CA7/EL34s on a 520 V choke-filtered supply.

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.
