Momentary 3PDT- how to wire so effect is turned on when stomped?

[skullservant]

So I've taken on the project to make a fuzz that uses a momentary 3DPT so that when the footswitch is pressed, the fuzz signal is engaged. I've got it all wired up, but it's doing exactly the opposite- the fuzz is on until I press the switch. Is there any way that I can change the polarity of the footswitch so that it is only engaged when pressed instead?

Thanks!

What you should have done is check what the default connections were, using a meter, before you soldered it up.  That scolding aside, you need to swap the connections to the outside lugs.  When you take apart a momentary stompswitch, you quickly realize there is very little difference between momentary and latching types.  The only difference is that the little rocker contacts inside have a tiny bend in them to prevent the stomp from pushing the contacts completely over to stay in contact with the other outside lugs.  They make contact for as long as you hold the switch down, and then when you let go, they do the only thing they can: go back and make contact with the other set of outside lugs they were touching up to a few moments ago.

So, you've wired it up such that the circuit board is connected to the default contacts.  Those lugs should now be wired up as the bypass, and the to/from wires from the circuit board should go to the other set of outside lugs.

Yup, just switch the bypass lugs with the efx in/out lugs.

Thanks guys. I'll do that.
