Roland TB-3 Touch Bassline


Categories: ,


Launched in 1981, the TB-303 continues to be an indispensable bass synth for dance music. In developing the TB-3, we’ve meticulously analyzed the circuitry of the original TB-303 piece by piece, right down to the individual circuit behavior. Using Analog Circuit Behavior (ACB) technology, we’ve fully reproduced the TB-303’s sawtooth and square wave oscillators, as well as the -18dB per octave ladder low-pass filter used in the original, capturing that unmistakable cutoff and resonance character.

In addition to the faithful reproduction of classic TB tones, the TB-3 is packed with new sounds that live and breathe. Bubbling synth basses, hard distortion basses, trippy delay sounds, and drippy effects—they’re all here, and then some.
