stewblack Posted January 11, 2020 Share Posted January 11, 2020 Excuse the utter imbecility of this, if it offends just move on. If I want to power a pedal with a centre positive socket is it simply a case of hacking off the centre negative plug from a power cable and shoving on a 3.5mm jack in its place?

I'd cut the power lead and rejoin it with the conductors reversed. Twist & solder the conductors, and tidy it all up with heatshrink sleeving. 3 Quote Link to comment Share on other sites More sharing options...

If that is the case then it might be a good idea to know what the pedal is. From what you are saying, I assume the centre positive power connection you refer to isn’t a 2.5mm barrel type?

Bassfinger Posted January 11, 2020 Share Posted January 11, 2020 Fit a new jack soldered to suit the polarity. Centre positive is more common place, bit guitar pedals seem to be t'opposite for some reason. Decent PSU's allow you to switch the pooatiry. 1 Quote Link to comment Share on other sites More sharing options...
Skybone Posted January 11, 2020 Share Posted January 11, 2020 In the past, I had a few pedals which needed a 3.5mm jack to power them from a PSU (ProCo Rat, EHX Small Stone/Small Clone). I simply modified a few of the leads with a 3.5mm jack I bought from the local music shop, figured out the positive & negatives, then soldered the leads to the jacks. Lasted for years with no problems. Sold the pedals and included the leads. 1 Quote Link to comment Share on other sites More sharing options...
