Airline GVC-9002A - Normal preset

Close · 72/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Airline GVC-9002A is a small solid-state combo from Montgomery Ward's Airline line produced in the early 1970s, when the brand had fully transitioned to Japanese-built, transistorized amplifiers following the Valco bankruptcy. It targets the student market with a compact, lightweight design and simple single-channel control layout. The solid-state circuit produces a clean, somewhat sterile tone compared to the vintage tube models but is reliable and low-maintenance. It is primarily of historical interest as a document of Airline's post-Valco manufacturing shift.

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.
