From the vendor

Clone board of the Guyatone PS-027 Loop Gate. It's a effects loop pedal. It's a noise gate. It's an effects loop with a noise gate! A severely overlooked, but extremely handy tool that allows you to either use it alone as a simple noise gate, or insert noisy effects into the loop, and let the gate take care of keeping them quiet when you're not playing. Brilliant!

Please note that this project uses the Coda silent relay switching bypass. A preprogrammed PIC chip will be required. The preprogrammed PIC chip is available here; http://www.deadendfx.com/product/coda-bypass-pic
