KORG volca nubass Vacuum Tube Synthesizer

Powerful and versatile bass synthesis with a sound source based around a vacuum tube oscillator.

Even today, when digital technology allows electronic musical instruments to simulate any sound imaginable, the warm harmonics and distortion produced by analog vacuum tubes is still sought after. This distinctive sound has a quality beyond words that sets it apart, and cannot be captured by a response curve; it’s the unmistakable sound of tubes.

The volca nubass is the first analog synth to be equipped with a Nutube new-generation vacuum tube in its oscillator circuit. By incorporating a vacuum tube, nubass produces a warm, thick, and rich sound, unlike any digital or transistor-based synthesizer. The familiar transistor ladder filter along with overdrive, and huge-sounding distortion, gives it the unmistakable character of a classic bass machine. Coupled with an LFO with flexible routing and sync, nubass also provides numerous possibilities for a new generation of music.

A truly unique bass machine for both classic and new sounds, with the power of modern synthesizer design. It’s the volca nubass.
