I have a guitar that I need to reverse the phase of the pickups in (to hopefully solve a piezo problem). The pickups are both two conductor Duncans - a Seth Lover and Antiquity. Does this mean that when I crack the guitar open, I'll have only two wires leaving each pickup - one to ground and one to the 3-way (hot wire)? And to reverse phase all I need to do is swap the wires for each pickup? Thanks for any advice you can give!
