Sano 300 / 500 Preamp - Channel 1 preset

Verified · 84/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Sano 300 and 500 share this two-channel tube preamplifier, which feeds a separate power amp. Channel 1 and channel 2 each have two inputs into a 12AX7 triode and their own bass, treble and volume controls. Channel 1 also feeds a 12AX7 and 6CS7 driving a Type 4C reverb bar with 12AX7 recovery, and a 12AX7 tremolo oscillator is switched by 2N5461 FETs from a dual footswitch. A 12AU7 handles the auxiliary stereo input.

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.
