Building on the success of its predecessor with a fleet of new features and built-in vacuum tube, the Korg Volca Nubass is a compact, affordable avenue to adding thick analog sound to your rig or diving into the world of synthesis. Built around a 16-step sequencer with a low-pass voltage controlled ladder filter, the Nubass lets you dial in big distorted sound with dedicated control for saturation on the sub-oscillator.
