I had a local tech fix my amp recently and when I went to pick it up, he had some cool basses there. One was an old Fender (wasnt a P or J...and Im not an expert so I dont remember exactly what it was). But, he had done some mods to it and one of them was a switch to put the pickups out of phase. It sounded awesome! Really funky but still subtle (i.e. not like an effect so much, just a little coloration if you know what I mean) I asked him if he could do it to my Geddy and he said yes and recommended a push pull pot to do it. Has anyone done this to their bass and if so, did you like it?
