The Caronline Guitar Effect Pedals - Somersault Lo-Fi Modulator is a chorus pedal from the well known pedal gurus in South Carolina. This pedal can tackle anything from subtle multi-track effects to full on warble vibrato. Select between two different wave-types, and mix in time, depth and rate like a typical chorus. The "Havoc" switch will let you ramp up the speed temporarily, which is a nice expression touch for real-time control.
