Original vintage Roland TB-303 Bass Line for sale, freshly serviced and in excellent working order. This is the real deal – the classic monophonic analogue bass synthesiser that shaped the sound of acid house, techno, and countless other genres since the mid-1980s.

Released in 1982 as a companion to the TR-606 drum machine, the TB-303 was initially a commercial failure – but its squelchy resonance, sliding pitch, and distinctive step sequencer made it a cult classic in underground music. Used and revered by artists such as Phuture, Aphex Twin, Plastikman, and Daft Punk, the 303's unique analogue voice remains one of the most recognisable sounds in electronic music.

This unit has had a full service and calibration by our techs and is working exactly as it should – ready to drop straight into your setup. Features include a built-in 16-step pattern-based sequencer, accent, slide, and transpose controls, and full CV/Gate input/output for syncing with other vintage gear.

With its saw and square wave oscillators feeding a resonant low pass filter, the TB-303 is capable of everything from subtle movement to wild, overdriven acid lines. Whether you're looking to recreate classic acid house sounds or push this iconic synth into new territory, this serviced 303 delivers the authentic experience.

Original Roland TB-303 – fully serviced, in great condition, and ready to make history again.
