I'm going to wire my second tele w/ neck & bridge pickups out of phase for the middle position. What do I need to consider re grounding or hum issues? Advice appreciated. The long version! I've had a push-pull pot switch for this o.o.p. option on another tele [tele#1] for a few years now and I love the sound - so much so that I simply never play the middle position in phase anymore. So, my next tele (#2, coming soon) will have it wired o.o.p. permanently, no switch needed. I'd like to do it right. Thanks.
