    Hi. I got given one of these older pedals in a batch from a friend of mine. He’s never used the pedals so I can’t get any info from him.

    The pedal is the older DMM E/C/V parallelogon shaped one. It has no info on it whatsoever about the power needs. The barrel part of the power adapter I have doesn’t even fit in there so I know I’m going to need a different supply but I don’t know where thee I need a centre positive or negative for the pedal.

    Searching online has given conflicting info and I don’t want to fry such a cool old pedal.Photo Here

    This is the correct power supply for your pedal. Not my listing.

    DMM power supply

    For future reference: 24vdc, 100mA, center positive

    Do you happen to know the correct adapter for the Holy Grail? I got one of those too. It has the weird socket that takes the same power adapter that looks like a little headphone Jack.

    It does say 9v but once again no indication of the polarity.

    The correct original adapter for that is the US9DC-500. 9vdc, 500mA, 3.5mm plug with positive tip.
