The Roland Boutique TB-03 is a compact and faithful recreation of the iconic TB-303 Bass Line, the synth that defined acid house and electronic music with its squelchy resonance and hypnotic sequences. Using Roland’s ACB (Analog Circuit Behavior) technology, it perfectly emulates the original’s distinctive saw and square wave oscillators, resonant filter, and signature slide and accent functions. The TB-03 retains the classic step-sequencer workflow while enhancing it with a modern LED display for easier programming, overdrive and delay effects, and expanded pattern memory for greater creative flexibility.
Bringing the TB-303 sound into the modern era, the TB-03 offers USB-C audio/MIDI, full-size MIDI I/O, and battery operation for portable jam sessions. It can be sequenced externally or used as a MIDI sound module, making it highly versatile for both studio production and live performance. Whether crafting authentic acid basslines or experimenting with new rhythmic textures, the TB-03 delivers the unmistakable character of the original 303 with added convenience and modern enhancements.
