EBS UniChorus produces Chorus, Flange and Pitch Modulation effects. The pedal incorporates analog processing circuitry using the high quality components, which results in a warmer and fatter sounding chorus/flange effect and long battery life. The entire audio spectrum is effected making this pedal ideal for bass or even guitar and keyboards. The EBS UniChorus is low noise chorus/flanger so is a perfect choice for the studio and recording environment, as well as live playing. It is also equipped with a FET-switch for noiseless switching during play. The LED indicates when the unit is working, and monitors the Rate speed dynamically.
