Magnatone 109 Melodier preset

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

The Magnatone 109 Melodier is a small Magnatone combo from Magna Electronics of Inglewood, California. Two instrument inputs and a microphone input with its own Mic Volume feed one half of a 12AX7, then Tone and Volume into the second half. The output is a push-pull pair of cathode-biased 6V6s, the second driven from a tap off the first one's plate instead of a separate inverter, on a 5Y3 rectifier.

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.
