Rickenbacker B115 preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Rickenbacker B-115 is a solid-state bass amplifier combo from the company's 1970s amplifier line, designed to pair with Rickenbacker basses like the 4001. It delivers a clean, full-frequency response with a firm low end and articulate high-mid definition, well-suited to the singing sustain and aggressive pick attack that Rickenbacker basses are known for. The circuit prioritizes fidelity over colorization, giving bassists a transparent platform to project the instrument's natural character. Rickenbacker's amp line was never as celebrated as its guitar line, but the B-115 is a competent example of 1970s solid-state bass amplification.

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.
