So I have this horrible buzz when my PP2 is connected to the holy grail. If I use the wall wart that the HG came with there are no problems. I don't understand it - at least not yet. I mean the PP2 is DC 9 volt and is matched for the HG. I don't see a discrepancy in voltage or polarity.

Has anyone else had a problem as such?

Thanks.

Hey Mo! Well I know that the Holy Grail uses a different Ma than any other EH pedal. I think its 250ma instead of the standard 500ma that the other pedals use. I had this problem when i used the wrong wall wart with this pedal. Untill i got the right one it just hummed a high pitched type ring. So the PP2 probly wont work????? Maybe you need a special adapter plug from Voodoo Lab?

Yeah, when it was hooked up to the PP2 the hum was crazy - more like a buzz, actually. The wart that the HG came with is fine. I think the HG is 500ma (not 250ma like you mentioned) although I can't confirm right now.

Yes, I might have to contact Voodoo. Thanks for you reply!

Yeah Mo! I may have it backwards....I dont remember really its either 250ma or 500ma.....

I think the PP2 delivers 9V @ 80ma, or something like that.

And, of course, that is the problem...

The Holy Grail draws 225mA
