Airline GVC-9060A preset

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

The Airline GVC-9060A is a single-ended Montgomery Ward practice amp. Two inputs share the first half of a 12AX7, which feeds a passive tone network with a Tone control, the second 12AX7 stage and a Volume control. One cathode-biased 6V6 drives a 4-ohm speaker for about 5 watts with no negative feedback, powered by a two-diode solid-state rectifier: a simple, early-breaking student amp.

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.
