Airline GVC-9052 - Channel 1 preset

Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Airline GVC-9052 is a large two-channel Montgomery Ward tube amp in which each channel drives its own push-pull pair of 6L6s and output transformer. Channel One has high and low inputs with treble and bass; Channel Two adds a phono/tuner input, a 6973-driven spring reverb and a valve tremolo with speed and intensity, both footswitchable. It drives an assembly of six 10-inch speakers, with a jack for an extension speaker.

Schematic-derived preset files for the Neural DSP Quad Cortex and 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.
