Sano Tremolo Combo (c. 1962) preset

verified · 86/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

A circa-1962 Sano tube combo with tremolo. Three inputs, one for accordion, each have a level control and mix into one triode of a 7025/12AX7, then a Volume and single Tone control. A 12AU7 gives a gain stage with speaker feedback and a cathodyne inverter for a cathode-biased push-pull pair of 7189s (high-voltage 6BQ5/EL84) into an 8 ohm 12-inch speaker. The other 7025 triode is a tremolo with speed and footswitch; a 5U4GB rectifies.

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.
