The Korg Volca Nubass Vacuum Tube Synthesizer features a real vacuum tube with Korg’s amazing NuTube technology so you get huge bass from a fantastically intuitive synth.

Real Vacuum Tube Synth

When Korg released their incredible NuTube technology they made serious waves in the music industry, making fantastic sounding valve amps at affordable prices.

The Volca Nubass is the first analogue synth to come with a Nutube powered oscillator, marking a great leap forward in the world of compact, portable synths.

You haven’t heard this much raw power in such a small synth before.

Giving you classic sound with the power of Korg’s cutting edge modern synthesizer design, the Volca Nubass is a bass machine for a new generation of music.

What A Difference A Tube Makes

The benefits of Nutube technology are countless but there are a few that make it ideal for compact modular synths such as the Volca Nubass.

For a start, Nutube requires, on average, less than 2% of the electrical power that conventional tubes need so they’re great for efficient battery operation.

Being less than 30% of the size of a conventional vacuum tube but featuring real triode structure, you can get huge, unmistakeable valve sound but from much smaller devices.

What’s more; they’re incredibly reliable. With construction being kept in Japan to ensure the top levels of quality controls, Nutube vacuum tubes give you tens of thousands of hours of continuous life expectancy.

Transistor Ladder Low-Pass Filter

Sharing a feature found on some of the most beloved classic analog bass synths, the Korg Volca Nubass is equipped with a low-pass filter.

Ranging from bright to dark and giving you a huge range of tonal characteristics, this transistor ladder low-pass filter allows you to add some seriously dynamic touches to your music in real time.

Plus, with such a great range to perform with, this filter can give you perfect sound for a wide variety of genres from acid house to techno.

Analogue Driver Circuit

The Volca Nubass modular synth comes equipped with an analogue driver circuit so you can get the type of overdrive you’d expect from a vintage stompbox.

Tun the knob clockwise to start compressing your volume, beckoning in some mild distortion to add some edge and girth to your bass sound.

Using the tone knob, you can also adjust the high frequency range to get the just right level of crispness for your liking.

16-Step Sequencer with Automatable Parameters

The nubass also features a complete 16-step sequencer with some great functions. You can easily connect the Nubass up to a rhythm machine such as Volca Beats and create great rhythm tracks or loop music.

The 16 buttons can be used for standard step input as you’d expect but they can also be played like a keyboard for real time performance and recording.

Another great feature of the Volca Nubass is pattern chaining, allowing you to play back multiple sequence patterns in succession, looping up to 16 sequences.

Using the motion sequence function, you can record knob movements too so parameter changes can be applied to your sound over time. Adding this to your loops and live performances is a great way to keep your tunes sounding fresh and dynamic.

With the active step function you can even choose to skip steps during playback to shake your music up and keep the audience on their toes.

Easy Groove Creation

Ensuring your artistry and creativity are captain of the ship all the way through, the Volca Nubass synth’s sequencer three distinct functions for intuitive grove creation.

With the Transpose function, the Nubass will play a note either one or two octaves higher within the original scale adding extra flavour to your tune.

Using the Accent feature, you can emphasise notes for added dynamics and more expressive rhythms with an organic vibe.

Last but not least is the Slide function that connects the notes together for smooth transitions great for that acid sound.

Furthermore, you can apply randomised settings to all three of these functions allowing your music to take on a life of its own.

Fantastic Connectivity

The Volca Nubass has a sync jack allowing you to easily connect to Korg groove machines and it’s the perfect partner for your existing Volca series units.

Hooking the Nubass up to the Electribe or SQ-1 also garners fantastic results with synchronised playback via the sequencer.

Adding even more creative potential, there’s a standard MIDI IN connector for hooking the Nubass up to your DAW.

Incredibly Portable Yet Powerful Bass Machine

Thanks to its innovative and powerful nutube technology, the Nubass is able to give you authentic valve sound from an incredibly compact unit.

What’s more, with its battery operation, built-in speaker and headphone output and modular functionality, you can make awesome music with the Volca Nubass anywhere, any time.
