When I bought my '66 G400 Pro secondhand, one of the p/p pots was already broken (came right out when pulled) and I've never really cared for the sound of split humbuckers anyway. So I replaced both p/p pots with regular ones. I never really bonded with the sound of the neck pickup, no matter how I adjusted it, swapped tone caps, whatever. Then I stumbled upon the idea of parallel wiring and it was just what I wanted. But I was thinking about other uses for p/p pots and maybe being able to switch between series/parallel on some other guitars, maybe phase too. So in looking around online I stumbled onto this page, https://www.fralinpickups.com/2017/03/29/push-pull-pots-mods/ and was surprised to find some interesting mods I'd never heard of before. The partial split, switchable tone caps, bright switch and switchable treble bleed are all quite interesting to me. Figured I'd share them here in case anyone else found them interesting too.
