Airline GVC-9048A preset

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

The Airline GVC-9048A (62-9048) is a solid-state Montgomery Ward instrument amp. Three inputs feed a single 40233 transistor stage, then one Tone and one Volume control with a High-Range switch and a Std/Aud voicing switch. Further 40233 gain stages and a 2N2102 driver feed a complementary driver pair and two 2N3772 power transistors with a bias adjustment, into a 4-ohm speaker and extension jack, with a play/standby switch.

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.
