is there any way to wire up a LP without adding extra swtiches or changing pots and still get the out pf phase sound? I would prefer not having to change out pots or add switches...
If your pickups have 4-conductor cable, to put them out of phase all you have to do is reverse the wiring of
one of the pickups - e.g. with a BKP swap the red and black wires so black is "hot" and red goes to ground.
If you have 2-conductor braided cable, you'd need to dismantle the pickup and flip the magnet to achieve the same effect.
Ive never used a push pull top so i dont know how they work so i will ask this (noob question!) Do they still work as the tone knob? say i was to take out the neck pup tone knob, replace it with a push pull one will it still act as a normal tone pot but if pulled up make the pup go out of phase?
Yes, just think of the push-pull as if it's two separate components - a pot and a DPDT switch. They're completely independent.
