Rickenbacker B410 B212 preset

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

The Rickenbacker B-410 and B-212 are solid-state bass amplifier combos from the 1970s, featuring 4x10 and 2x12 speaker configurations respectively, targeting professional and semi-professional bassists. Both amps deliver clean, high-headroom solid-state amplification with a relatively flat frequency response, complementing the bright, piano-like attack of Rickenbacker basses. The multi-speaker configurations provide additional projection and low-end dispersion suitable for medium-sized venues. These represent Rickenbacker's most serious commitment to bass amplification during their amp-making years.
