Hello ladies and gentlemen. I've got a few questions. I'm replacing my input Jack on my '15 MIA P Bass. What is the correct Switchcraft Jack do I need and how do i know I'm getting the real deal. Also, I was considering switching the potentiometers for the volume and tone. Which brand do yall suggest? Also, what is this Fender "TBX" treble bass expander potentiometer all about? Are there any other tone potentiometers that do better specifically for the P Bass or that style of passive bass? Thanks!
