Love that squelchy, iconic acid bass sound? The Behringer TD-3 is a faithful, affordable recreation of the classic Roland TB-303 Bass Line. It's a true analog synthesizer, built with matched transistors and the same VCO (Voltage Controlled Oscillator), VCF (Voltage Controlled Filter), and VCA (Voltage Controlled Amplifier) architecture that made the original famous. The heart of the sound is that juicy 24 dB/octave filter – twist the Cutoff and Resonance knobs to go from smooth bass to screaming leads. It has a built-in 16-step sequencer to program those infectious patterns, plus a distortion effect for extra grit. You can connect it via standard 5-pin MIDI In/Thru or USB-MIDI. The \Poly Chain\ feature is cool: link multiple TD-3s together to get up to 16-note polyphony! Output is via a 1/4\ jack. Whether you're making techno, house, or just exploring analog synthesis, the TD-3 is a super fun and authentic way to get those legendary bass tones.
