Korg volca nubass Vacuum Tube Bass Synthesizer
Brand
KORG
Searching for an analogue bass synthesizer that delivers the unmistakable, squelchy grit of a classic acid house groove machine? The Korg Volca Nubass is a groundbreaking, ultra-portable bass synthesizer powered by a real, next-generation Nutube vacuum tube integrated directly into its oscillator circuit. Operating on either six AA batteries or an optional AC adapter, this pocket-sized instrument breaks away from cold digital emulations to deliver the authentic, harmonic warmth and fat low-end roar that only true tube technology can provide.
KORG volca nubass Vacuum Tube Bass Synthesizer
The KORG volca nubass is a compact analog bass synthesizer designed for deep, aggressive, and harmonically rich basslines. It is part of the volca series and stands out due to its use of KORG’s Nutube vacuum tube technology in its oscillator circuit, delivering a distinctive warm, saturated tone with strong harmonic character.
Built for electronic musicians, producers, and live performers, the volca nubass combines a vacuum tube oscillator, sub-oscillator, transistor ladder-style filter, and analog drive circuitry with a hands-on 16-step sequencer. This makes it ideal for acid basslines, techno grooves, experimental sound design, and live performance workflows where immediate control and sonic character are essential.
Nutube Vacuum Tube Oscillator
At the core of the volca nubass is a newly developed Nutube vacuum tube integrated into the oscillator circuit. This adds natural harmonic saturation and dynamic response that is difficult to replicate with purely digital or transistor-based designs.
- Nutube-based vacuum tube oscillator
- Warm harmonic distortion and saturation
- Sub-oscillator for deeper low-end layering
- Analog signal path for organic tone shaping
Analog Filter and Drive Circuit
The nubass features a classic-style transistor ladder low-pass filter combined with an analog overdrive circuit, allowing for a wide range of aggressive and expressive bass textures.
- Transistor ladder low-pass filter
- Resonance control for acid-style tones
- Analog overdrive circuit for saturation and grit
- Tone shaping for bright or dark bass character
Acid-Style Sequencer Workflow
The built-in 16-step sequencer is designed for real-time pattern creation and performance flexibility, making it easy to build evolving basslines and rhythmic sequences.
- 16-step sequencer with pattern chaining
- Real-time and step recording modes
- Motion sequencing for parameter automation
- Active Step and Step Jump functions for live variation
- Accent, transpose, and slide functions for expressive basslines
Performance-Oriented Sound Design
The volca nubass is optimized for hands-on control, allowing instant manipulation of sound parameters during performance or recording.
- Direct knob-based sound shaping
- Real-time filter and drive control
- Dynamic modulation via motion sequencing
- Ideal for live improvisation and studio experimentation
Portable Analog Bass Machine
Designed for mobility, the volca nubass is compact, battery-powered, and highly portable, making it suitable for studio setups, live rigs, and mobile music production.
- Ultra-compact volca form factor
- Battery-powered operation
- Built-in speaker for quick monitoring
- Lightweight design for portable setups
Connectivity and Synchronization
The nubass integrates easily into hardware and hybrid setups, supporting synchronization with other volca units and external MIDI equipment.
- MIDI input for external control
- Sync In/Out for volca ecosystem integration
- 3.5 mm audio output
- Compatible with DAWs and hardware sequencers
