I was going to sell my 2017 CU22 SE after I recently bought a new McCarty, as I was never really happy with it - constantly retuning it (even with a Core nut) and not crazy about the pups. But when I didn't get any offers for the SE, I figured, what the heck, I
am going to like this guitar. So after a visit to John Mann last weekend, I came home with a set of PRS SE retrofitted locking tuners, and amber knobs. Installed those, and then last night I tweaked the 85/15S pup heights to a happy place, and then added a push-pull tone pot for coil taps - the rewiring went smoothly, and I added the 2.2K and 1.1K resistors to the push-pull (like in my Core.) Finally, added a drop of high quality bicycle lube (TriFlow Teflon) to each trem screw knife edge and to the saddle grooves. Well, I'm happy to say, the guitar is a different animal all together now. Sounds great and plays so much better. Of all the mods, the Core amber knobs made the biggest difference to the guitar.
Also, for some reason, PRS locking tuners just seem right on a PRS headstock.
