HI,
I picked up a Donner Echo Square Delay Pedal today. I plan to use it very sparingly in my tribute band, so didnt' want to go out and throw £150+ at it.
When I use my PSU direct into the pedal, it's great. No problems. However, when I plug the PSU into my JOYO Multi Power Supply and click the pedal to engage it, an almighty low end noise occurs. It's like a low-end alarm clock.
I think I'll have to power my other pedals with the JOYO, and use a separate PSU for the Donner, but before I go off and buy one, does anyone know what is causing it?
FYI no matter where I put the pedal in the chain; it makes the sound. It's literally caused (I think) by the JOYO
