I've done a fair amount of wiring harness and upgrade work over the years, but this will be my first semi-hollow effort.
022u, new push back wiring, and set of SD Seth Lover 4 wire PU's (the Epi PU's were really not bad, but after looking at the amount of work it is to access the harness I figure the guitar was worth the extra $220 investment). I have all my parts, new Bourns push pull pots (500K), and Bourns tone pots (500K), new SwitchCraft selector & jack, PiO caps. I really love this guitar and use it quite a bit, after watching a number of videos on center block semi-hollow body wiring harness upgrades decided that if I'm going to do this, then lets do it one time. I do use the coil split quite a bit so I'd like to keep it. It's still working on the 'in' position but the shaft action continues to degrade. One of my push pull pots gave it up a few months ago, shaft pulled out.
