Kalamazoo Model 1 preset

verified · 92/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Kalamazoo Model 1 is the smallest amp in Gibson's budget Kalamazoo line: a 12AX7A preamp driving a single 6BQ5 (EL84) output tube, with a 6X4 rectifier and about 5 watts. It has just volume and tone and, unlike the Model 2, no tremolo. It saturates early, making it a popular small recording amp.

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.
