This is a reverb, with a pitch shifter built in. There's an internal rotary switch that allows you to select your preferred flavour of chaos... as it is currently set, you get reverb with a nasty harmonised extra pitch controllable via the 'rate' control, but reverb+chorus type options are available too apparently. It's heaps of fun and looks like a pack of Starbursts.
