Airline GVC-9045A preset

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

The Airline GVC-9045A is a small single-ended Montgomery Ward tube amp with a 10-inch speaker. Low and High inputs feed two 12AX7 stages with Volume and Tone controls between them, driving one cathode-biased 6V6 for about 5 watts off a 5Y3 rectifier. A second 12AX7 runs the tremolo oscillator, with a Speed control that also switches it on and a footswitch jack.

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.
