Roland TB-303

The Roland TB-303 is a compact electronic musical instrument introduced in the 1980s, originally designed to simulate bass guitars. It features a built-in sequencer that allows musicians to create repeating bass patterns and melodies by programming notes directly into the device. Its distinctive sound is characterized by a resonant, squelchy, and rhythmic tone, which became foundational in genres like acid house and techno. The TB-303’s unique sound can be altered through controls for filter, resonance, and distortion, making it highly expressive and influential in electronic music production.
