Airline GVC-9002A preset

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

The Airline GVC-9002A is a small solid-state Montgomery Ward practice amp with a 6-inch speaker. Three input jacks feed a single 2N3711 transistor preamp stage, followed by Tone and Volume controls and a PA-237 integrated-circuit power amplifier. A two-transistor phase-shift oscillator adds tremolo with a Speed control and a footswitch jack, all running from a low-voltage transformer 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.
