The TC Electronic Mimiq Doubler is a unique pedal that instantly creates the sound of ADT, multi-tracked and layered guitars. Get the effect of having two to four guitars or stereo keys at once with subtle variations in timing, attack and pitch to create the same massive sound you'd get overdubbing in the studio. Stereo I/O lets you spread the effect out across the stage and turns stereo synths and keys into mammoth walls of sound with a stomp of the footswitch.
