This amazing boutique pedal, only made between 1986-89 would be a fantastic addition to your pedal board or collection. Featured in JHS Pedals video "12 Legenday Chorus Pedals". Through the use of dual modulation, the TC10 allows deeper and more realistic chorusing than the SC10 without as much chance of offensive side effects such as phase shifts (causing amplitude drops at regular intervals), out of tune notes or chords and periodic sweeps unrelated to the tempo of the music. By modulating at 2 different speeds and depths simultaneously, less depth or width (change in delay time) is needed to create and obvious effect. The TC10 is the very best effect you can use to create a stereo image using two amps. Does not come with original box, pedal only. In great shape and excellent cosmetically.
