    This is the best! Unfortunately I purchased most of the components elsewhere, but I found this kit while looking for wiring diagrams. Next time I'm upgrading a guitar I will stop here first. Excellent information, descriptions, & instructions. Thanks!

    Used this kit in my 2008 Epiphone Dot to great effect! combined with non-wax-potted PAFs it absolutely chimes now, and all the controls make meaningful differences in tonevs the stock electronics. Clear instructions, and the resulting harness has good flex and strength to make installation a little easier than it could otherwise be. The treble bleed is particularly nice, makes the volume knobs into more of a saturation control. It’s worth noting the top of my guitar was thicker than the switch and jack threaded shanks are designed to accommodate, and the switch doesn’t come with a tip, so you’re gonna want to add a deep-collared switch nut and a switchcraft-threaded switch tip to your order if you go this route (or re-use the stock parts, which I did with the jack).
