The Behringer TD-3 is a fully analogue bass line synthesizer based on the legendary TB-303, the synthesizer that played a major role in shaping the sound of house and EDM.
The TD-3 synthesizer brings classic vintage synthesizers into the modern era. This compact and highly portable bass synthesizer faithfully recreates the original circuitry with a purely analogue signal path. The TD-3 offers a wealth of integrated controls, including a 16-step sequencer with 250 pattern memory slots. The original was known for its distinctive squelch-style bass sounds, which played a decisive role in shaping the sound of popular dance music.
The TD-3 features the same 4-pole low-pass resonance filter and the same distortion function that made the original so versatile. The new and improved design offers the same sound and controls as the original, with additional MIDI and USB connections for modern music production.
