Korg Volca NuBass Vacuum Tube Bass Synth

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 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 fusion of a newly developed vacuum tube oscillator with a classic ladder filter.

A vacuum tube oscillator circuit forms the heart of volca nubass, utilizing groundbreaking 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.

A transistor ladder low-pass filter that produces a distinctive sound.

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; you can use it to create the distinctive modulation that can be heard in acid house, or increase the resonance to bring out a sharp character that's appropriate for techno.

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.

Volca sequencer makes performing and composing simple and intuitive.

A 16-step sequencer that lets you automate parameters.

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.

You can use the 16 buttons for step input just like the rest of the volca series, or play the buttons as a keyboard for realtime recording. The chain function lets you play back multiple sequence patterns in succession, allowing you to loop up to 16 sequences.

The motion sequence function can record knob movements, applying parameter changes over time to the sound. This can be used when creating loops, or for live performances that are dynamic and original. Up to 16 sequence patterns together with motion sequences can be saved in internal memory.

There's also an active step function that lets you skip steps that you specify during playback; sequence patterns become more dynamic and exciting when they can be edited in real time during performances.

Three functions to create grooves on volca nubass

The sequencer of the volca nubass provides three functions that add the slap and slide performance techniques that are distinctive of acid bass: these transpose, accent, and slide functions are accessible and controllable through the step sequencer.

Transpose is a function that plays a note one or two octaves higher; it adds movement to the bass line while staying within the original scale. Accent emphasizes a note, creating dynamics that make the rhythm expressive. And the slide function that's indispensable to acid sound creates a smooth transition to the next note. Use these functions to add a sense of groove, and volca nubass will come alive in your performances and compositions.

Randomize settings can be applied to each of these three functions. In addition to generating unpredictable patterns, you can update the randomize settings to keep varying the patterns, bringing out more unexpected and exciting ideas from the sequencer.

Excellent playability.

Connectors that allow synchronized performance and external control.

Since this unit provides a sync jack for easy connection to Korg groove machines, you can connect it to another volca series unit or to equipment such as an electribe or the SQ-1, and enjoy synchronized playback with the sequencer. There's also a standard MIDI IN connector, so you can use the volca drum as a sound module for your DAW.

Enjoy anywhere.

Compact, size, battery operation, and built-in speaker mean that you can take this unit anywhere and enjoy playing on the go.

Free bundle of music software.

The volca nubass comes with a diverse variety of music software from Izotope including “Ozone Elements” which lets you not only create songs but also master them using AI, “Skoove” which will help you improve your keyboard playing skills, “Reason Lite” DAW software, as well as software synths from KORG and other brands.

In other words, the moment you get your hands on this synthesizer you'll have a variety of tools to help you take your music to the next level.

Warranty FAQ

DO I NEED AN EXTENDED WARRANTY?

Most manufacturers limit their warranty periods to keep their product costs competitive. It should come as no surprise that most problems occur after the manufacturer’s warranty is over. If you are like most consumers, you don't want to deal with the inevitable problems surrounding repairs. Who do you call for service? Are they reliable? Is a handyman capable of performing a long lasting, reliable repair on your instrument?

Ranked #1 Extended Warranty

CPS Warranties Offer Reliable Protection for Your Product

What’s the difference between a Replacement Plan and Repair Plan?

A Replacement Plan is available for products under $150. If the product fails, you will receive a replacement through Bananas.

For the Repair Plan, you are covered for a period of up to five years (depending on which plan you purchase). Benefits include parts and labor for required repairs on your product.

When does my warranty coverage start?

Coverage begins on the 31st calendar day from when you purchased your product.

Can I transfer the Protection Plan to a new owner?

Yes! CPS Warranties are transferable between owners.

What if I Need to Return my Product?

If you return your product, Bananas returns the money you paid for the product protection plan. Depending on how much time has passed since your purchase, CPS may issue a prorated refund.

Is my product covered if it’s stolen or if I lose it?

Unfortunately the CPS Warranty does not cover lost or stolen products.

Is there a service fee?

Zero dollar service fee for the Replacement Plans and the Repair Plans.
