Joyo Digital Delay Problems

Postby tuftywarden » 29 Mar 2017, 14:02


I joined the forum as I have a faulty Joyo Digital Delay and very limited knowledge of electronics!

As far as I can tell the board looks to be in tact. I found another thread which recommended checking if the IC heated up during use. It doesn't.

There is power (the LED comes on. Guitar passes through when off, but not when on. If I turn up the Level pot it produces a horrible squeal.

If anyone has any clues on how to fix this, I'd really appreciate it!
