I have a new, boutique delay pedal with tap tempo, and just performed a guitar clinic and the delay, even when bypassed sent a pulse through my amp. Strange for a couple of reasons...It's a true bypass pedal, and also, whatever tempo you tapped into the delay would feed a pulse the same tempo coming out of the amp.

I've tried changing guitars, cables, power supplies (1 Spots), even tried this at home with the same problem incase it was a grouding issue. and still no luck. Is there anybody who knows what is causing this?

I've used it another time, about a month ago, and no problem at all. This just happened this past weekend. Any rational advice is appreciated.
My Echo Park does this, I just put it in my effects loop with a noise gate before it.
