I'm making another Beavis tap tempo switch for my Boss DD5, but I need one that is reverse polarity. How would i wire this simple switch to accomplish this?

Kindly bump.  :D

I have the day off and would love to rewire this to work, all help is greatly appreciated.

What sort of switch are you using? To be able to reverse the polarity you need a SPDT or DPDT momentary switch, if you use the middle and one outside lug you get one polarity, eg: switch is open and closes when you press it. If you use the middle lug and the other outside lug you get the opposite eg: switch is closed and opens when you press it.

So I could just use the opposite kind of switch? I'm pretty sure it's an NC right now, just swap it out for an NO?

Yeah, you can just use an NO or NC switch depending on which polarity you want.
The nice thing about using a double pole switch is you get NO and NC in one switch, so you could add a toggle switch to give either polarity.
