    Hi Guys,

    I have a problem: When I engage my Holy Grail Reverb (the older, chunkier version) I have a high pitch frequency that comes with the reverb. It hasn’t always been that way. Does anyone else have that problem or a solution to it? The pitch goes away when the pedal is off.

    Thanks.

    I know that mine sounds bad if I don’t use the EHX Power Supply.

    The pedal requires 220mA – check your power supply.

    Thanks for the note. My power supply is the original, EH supply that came with it. I once tried to use another supply, but that didn’t work out for my configuration, so I went back to the original.
