The EBS UniChorus is a 3-in-1 modulation pedal built specifically for bass, but still equally useful for all sorts of electric instruments. Designed to keep the full frequency range in tact, the UniChorus switches between chorus, flanger, and pitch modulation modes and straightforward control for rate and depth of the effect. Rounded out by stereo outputs and true bypass, the UniChorus is a great high-end option for all things bass modulation.
