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

Part of Rickenbacker's 1989 solid-state RB bass amplifier line, which shares one preamp design across the RB30, RB60 and RB120 and pairs it with a power stage sized to the model. The RB30 is the 30-watt version, built for practice and small rooms.

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.
