Airline GVC-9052 - Channel 2 preset

Close · 76/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Airline GVC-9052 is a solid-state Airline model from the mid-1970s notable for its relatively high power output within the budget-focused GVC series. Manufactured in Japan, it was aimed at players needing rehearsal or small-venue volume from an affordable amp. The circuit provides two channels with basic EQ and a solid-state output stage capable of clean, undistorted reproduction at moderate levels. The GVC-9052 represents the end of the Airline amplifier era, as Montgomery Ward began winding down its instrument sales operation by the late 1970s.

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.
