PNP Fuzz power

[wretched]

Probably a dumb question, but could I just change the polarity on the DC plug for a PNP fuzz pedal? Like connect the negative to the positive on the jack?

I am guessing it will create problems seeing it seems like the easiest way.

I'm pretty sure you can do that.You'll have to sacrifice that power transformer though.

You can only do this if the transformer power output is isolated. If you use a separate transformer for the one pedal or if your transformer has isolated taps it will work. If the taps aren't isolated, doing this will cause a dead short from the power rail to ground. You would also need to mark the jacks well and remember what you did. The problem is that everyone is really used to one standard with the 2.1mm DC jacks. MAcking a mistake and plugging into the wrong power supply is just way too easy.

My personal preference is to do something to generate the negative rail in the pedal.

I tired this with a 1Spot I had years ago and like RobA says

No worky.

My approach is, from what i've measured, my positive ground pedals with high intensity LED's draw such a small amount of current, batteries seem to last forever so i just go with a battery.

You could add a charge pump circuit to your pedal such as Madbean's  Road Rage and then you could you add it to your string of powered pedals with no worries over the mixed grounds.
