I bought an Epi Les Paul Custom in Silverburst new in 2008. After a few months I swapped out the pickups for the Duncan Hotrodded set (SH-2 / SH-4). When I did the pickup swap I just left the stock wiring in the guitar. I didn't really know what I was doing and I was actually amazed when I buttoned it back up and everything worked as it should. My soldering skills remain pretty weak to this day. I was in a modding frenzy for a few years with all my gear but pretty much left the Epi Custom alone after the pickup swap. The only other mod I did was install a GFS brass bridge and tailpiece last year. I've remained extremely happy with the guitar and I think it sounds and plays beautifully. The action and intonation are very good, it sounds good through my amps and I think it is my best playing guitar even vs. my Elitist or my Clapton strat. It just feels and sounds right in my hands. So I've read a lot of posts that advocate throwing the stock harness in the trash and going with 50s style wiring with new switch, pots, caps and braided wiring. Full disclosure - I have had zero issues the the stock harness, pots are quiet, switch works, and I like the taper of the volume and tone controls and the stock caps sound fine to my ears. I do think that pio caps are snake oil. I'm asking for opinions on what would be the benefit to upgrade the harness at this point?
