The True-Bypass is a compact single-loop true-bypass box, designed for maximum versatility at the lowest cost. Like its big brother Roundabout, the True-Bypass works both as a true-bypass box, as well as a guitar and/or amplifier switcher.
The True-Bypass represents the very best in single-loop design. With its low power consumption, ease of use, and superior design, the True-Bypass delivers the best bang for your buck of any true-bypass looper on the market.
The "In" and "Out" jacks are your guitars signal. "Send" and "Return" are for the pedal you want to true-bypass. The switch turns the effect on or off and the LED indicates such.
