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 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.

Powered by the Korg Nutube

A vacuum tube oscillator circuit forms the heart of volca nubass, utilizing ground-breaking Nutube technology. 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.

Transistor ladder low-pass filter

The low-pass filter defines the sound of this bass machine; it uses a transistor ladder design found on classic analog bass synths. This filter is uniquely 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 dance music.

Analog driver circuit

Nubass is equipped with overdrive that uses an analog circuit reminiscent of a classic stompbox. Turning the knob toward the right compresses the volume while causing mild distortion, adding thickness to your bass sounds. The tone knob also lets you adjust the crispness of the high-frequency range.

I bought this for my son for Christmas after he showed an interest in my Behringer Model D. As we are new to this we were struggling a bit with the model D so I thought the Korg would be an easier way for him to make progress as he likes the Rhythm loop. It worked out really well - he loves it - quick and easy way to gain some confidence and make some tunes. He is already talking about saving up for one of the other volca components.
