The Korg Volca Nubass Vacuum Tube Synthesiser with 16-Step Sequencer features a sound source based around a vacuum tube oscillator and a classic ladder filter, well suited for producers and performers looking for warm harmonics and huge distortion produced by analogue vacuum tubes for the ultimate bass machine.

The Nutube contains two independent triodes; one is used in the oscillator to generate a sawtooth wave or square wave. The other triode is used in the drive circuit of the sub oscillator, adding depth and warmth one octave below the oscillator. The low-pass filter is remarkably dynamic in the way it affects a sound more than just ranging from bright-to-dark. Its wide range of timbral possibilities makes it ideal for a broad variety of electronic music, including the distinctive modulation that can be heard in acid house and techno. The driver circuit uses an analogue circuit reminiscent of a classic stompbox, which introduces compression and mild distortion to create a thickness to your bass sound, while the tone knob adds crispiness to the high-frequency range.

The synthesiser can be controlled with its multitouch keyboard or the built-in 16-step sequencer with slide, accent, and transpose functions. The sequencer has 16 memory patches for storing your settings and an Active Step function that can remove or insert steps to help create new bass lines. The unit can receive MIDI from an external controller or DAW via its 5-pin DIN connector. Multiple units from the Volca line can be clock synced with the 1/8" Sync In and Out connectors. The Korg Volca Nubass includes a sync cable and can be powered by the included six AA batteries or with the optional KA-350 AC adapter.
