Ampeg SST - Channel 2 preset

Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Ampeg SST is a solid-state guitar amp drawn in 1969, sharing its power amp with the SBT bass model. Both channels have bright and normal inputs with volume, bass and treble; channel 1 adds Bass Cut and Ultra Hi switches and a midrange control with a three-position switch on a toroidal inductor, channel 2 Ultra Lo and Ultra Hi. Echo (reverb) with Timbre and Dimension and an oscillator-driven vibrato/tremolo module complete it, into four 16-ohm speakers.

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.
