The Korg Volca NuBass is a powerful bass synth with a sound source based around a vacuum tube oscillator. The acid bass machine with the pinnacle of modulation and distortion.

Even today, when digital technology allows electronic musical instruments to simulate any sound imaginable, people seek the warm harmonics and distortion produced by analog vacuum tubes. 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 Korg volca nubass is the first analog synth to be equipped with a Nutube new-generation vacuum tube in its oscillator. Vacuum tube plus analog means that the sound is warm, thick, and rich. The familiar transistor ladder filter gives it the character of a classic bass machine, along with overdrive, and huge-sounding distortion. An acid bass machine for a new generation combines classic sound with the power of modern synthesizer design. It's the volca nubass.

The Nutube is equipped with two vacuum tubes; one is used in the oscillator to generate a sawtooth wave or square wave. The other vacuum tube is used in the drive circuit of the sub oscillator, adding depth and warmth one octave below the oscillator. This oscillator and sub oscillator provide a circuit structure that brings out the harmonic character that only a real vacuum tube could provide.

The volca nubass is equipped with a full-fledged 16-step sequencer with a variety of functionality; by using it in conjunction with a rhythm machine, you can construct rhythm tracks or loop music.
