Rob Robinette SLO Nakid Micro 12AU7 preset

Verified · 93/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The SLO-Nakid Micro is Rob Robinette’s 1-watt Soldano SLO-100 reduced to its overdrive channel, with the clean channel, effects loop and switching deleted. Four cascaded 12AX7 gain stages with OD Gain and a cold clipper feed a cathode-follower-buffered treble/bass/mid stack and OD master, then a 12AX7 long-tail inverter with presence and optional depth. Both halves of a single 12AU7 run push-pull into a Hammond 125B; a 12BH7 gives about 2 watts.

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.
