Hi all,

Just looking for some advice on an issue I've encountered on my ProCo Rat 2 pedal.

The input jack for the 9v power supply is a lot smaller than usual on UK pedals so I'm assuming that the smaller input is a US thing. I'm trying to build a pedal board with a shared power supply and the fact that this pedal has a different jack than all of my other pedals is a bit of an issue.

Does anybody know of any good fixes to this problem? Is there a well known US to UK tip adapter or anything like that?

Appreciate any help you can offer!

It is not a US to UK thing. The typical 2.1mm barrel, center negative, 9vDC supply power cable is the world standard for powering pedals. The RAT is just weird, on either side of the pond. It uses a 3.5mm male plug (like a headphone jack), tip positive.
