ES-335 Pro wiring harness | Epiphone Guitars Nov 26, 2015I have an Epiphone ES-335 Pro (sweet guitar by the way). It came with crappy push pull pots for the volumes, and mediocre pots for tone as well. So I brought it in to a local tech to install a new wiring harness. I gave him the pots and caps and jack that I wanted to use, and told him I wanted 50's wiring. es 335 wiring harness | eBay Find great deals on eBay for es 335 wiring harness. Shop with confidence.
