Analog bass line synthesizer with VCO, VCF, 16-step sequencer, distortion effects, and 16-voice poly chain. Only produced from 1981 to 1984, the Roland TB-303 was a tremendous commercial flop as a replacement for the bass guitar; however, it soon found its place as one of the most-loved synthesizers for what became known as electronic dance music (EDM). An ultra-affordable and faithful homage to the iconic synthesizer that spawned house music, plus an all-new distortion circuit, the TD-3-BB lets you conjure up virtually any sound with incredible finesse and ease. With its pure analog signal path, 16-step sequencer, and authentic VCO, VCF, and VCA filters, the TD-3-BB is sure to become one of your favorite synthesizers.

Great care has been taken in engineering the TD-3-BB, including the true-to-the-original VCO, VCF, and VCA designs and pure analog circuitry with matched transistors. This highly-focused attention to detail is what gives the TD-3-BB its ultra-flexible sound shaping capability, which covers everything from super-fat bass and lead tones to stunning effects – all the way out to the otherworldly sounds of your imagination.
