The Korg Volca NuBass delivers the harmonic richness and punchy dynamics you can only achieve with tubes, because it's packed with tubes — Nutube technology, to be precise. One Nutube drives the oscillator (your choice of saw or square waves), and one Nutube is used in the overdrive circuit for the sub oscillator. Factor in the classic ladder filter design with its undeniably rich character, and it's clear the NuBass module is primed for ultra-fat bass tones. Best of all, the built-in sequencer offers transpose, glide, and accent functions — perfect for acid-style bass lines. Whether you're already a fan of the Volca series or you're simply looking for a great value in a bass-focused synthesizer, we're sure you'll be impressed with the Korg Volca NuBass synth module.
