Unknown Martin 112 preset

Close · 60/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Martin 112 is an unattributed amplifier likely from a smaller or regional manufacturer, the model number suggesting a 1×12 combo configuration. Without confirmed manufacturer attribution, full specifications and historical context remain uncertain. The schematic is preserved here for research and restoration purposes.

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.
