Loop Switchers 5 Channel True Bypass Guitar Effects Pedal

Best way to describe,Take the input and output from vintage pedal, into loop bypass switcher and have a extra on/off switch. I have a very old Boss pedal the built in on/off switch is about to quit. Loop switcher extends the use of the old pedal!-other notes, no power supply included with loop switcher. FIND 1!I’m using a Boss PSA-120s or aEHX 200ma 9.6v output. Does fine!-other remarks keep digital pedals with own isolated power supply, not doing this with feed signal such as a ground loop or other unwanted signal from digital pedal, into the looper switch and will then send to other pedals, and/or amplifier.Not pleasant! Would not recommend a parallel dc power cable to power looper switch then to also power digital pedals.-final notes, this switch looper isn’t labeled with input or output markings for pedals or output to send to amp or input from guitar.But it is simple to figure out how.It’s powdered coated and a strong metal box! It may be shielded, but can be opened to extra shielded should you want to. Your experience may vary. No digital memory bank for this, looper switcher bypass,but I didn’t need it.Helps to keep cost down.I love mine very much!
