Thanks for that information. I don’t plan on having the pedal on top of the amp in general. I was just testing and noticed all the noise. I’m keeping it off the amp from now on. And I asked another question in another thread about power supply milliamps and you just answered it here. Thanks. So I guess the minimum milliamps should be 100ma. I think it is rare for a PS to be less than 100ma but I suppose there are some out there.
