Am I correct in thinking the old NYC EHX pedals are Centre Positive?

yes. there are reverse polarity adaptors so you can daisy chain everything

Yeah, the little headphone jack connector adapters. I think old MXRs need them, too. Look on the Johnnyshredfreak website, he has them.

Don't rats also use that connector?

Lots of old pedals do, I have an old Ibanez pedal that is a 3.5mm headphone jack style.


Thanks for the conformation of the centre positive though guys :wink:

No idea, maybe, they seemed to be fairly common in them good old days of unstandardised equipment.

Just thought, save arseing about with "adapters" couldn't I just drill a big hole in it and wire in one of these in the usual centre neg orientation?

the adapters only cost a few pounds and slot on to a daisy chain of the usual centre neg adapters. i use one for my rat like that. less hassle

These are the same jacks on the old boxed Small Clone Chorus like mine. The Voodoo Labs Pedal power 2 even included power jumpers for them. The newer Neo Clone was converted over to the standard 9v plugs

I remember when I borrowed a NYC Big Muff and I used my SCC power adapter to power it.
