The Roland TB-303 Bass Line is a classic analog bass synthesizer whose unmistakable sound helped define acid house and techno. Its distinctive resonant filter and programmable sequencer deliver everything from rounded bass grooves to the squelchy, sliding patterns that made the 303 legendary.

Features include selectable sawtooth and square waveforms, hands-on filter cutoff and resonance controls, envelope modulation, decay, and accent. The built-in sequencer’s accent and slide functions add the expressive movement central to its signature sound. DIN Sync input and CV/Gate outputs provide connectivity with compatible equipment.

A landmark instrument for electronic musicians, producers, and vintage synthesizer collectors.
