The world's first bass synth in a standard-sized stompbox. It turns your bass into a synth bass for hip-hop, dance, or urban funk styles. 2 separate outputs let you mix a straight bass sound with synth bass, and 11 different modes give you a variety of synth-bass effects. A hold function sustains a synth note while you play over the top of it. A T-Wah effect provides a classic synth-wah tone..
