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.
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.
