Celebrating thirty years since the beginning of acid house and rave culture in the UK, design and art studio Entwurf have designed this Roland TB-303: Summer of Love 88-89 edition screenprint to celebrate the key synthesizer that became the true sound of this movement.

As Entwurf explains: "The TB-303 (short for "Transistor Bass") was originally marketed to guitarists for bass accompaniment while practising alone. Production lasted approximately 18 months, resulting in only 10,000 units. It was not until the mid- to late-1980s that DJs and electronic musicians in Chicago found a use for the machine in the context of the newly developing house music genre.

The well-known "acid" sound is typically produced by playing a repeating note pattern on the TB-303, while altering the filter's cutoff frequency, resonance, and envelope modulation. The TB-303's accent control modifies a note's volume, filter resonance, and envelope modulation, allowing further variations in timbre.

The TB-303 is the sound of acid and techno house music. It's a monophonic analog bass synthesizer married to a pattern-based step sequencer released in 1982. It features a single analog oscillator with two waveforms (ramp or square) and has a simple but excellent VCF (filter) with resonance, cut-off, and envelope controls. There are also knobs to adjust tuning, envelope decay, tempo and accent amount."
