I was going to ask about tuning stability but felt a bit scared asking about that on this forum.
So far I haven't really had much luck getting noteworthy tuning stability from the several CU24 I had/have, including a Private Stock one.
The PS had binding on the G string (and maybe B too) but also extremely rough slots which definitely weren't helping wound strings be stable even with lubricant. I left the benefit of the doubt on biding (maybe caused by not playing the guitar for a while), but the rough nut slots didn't become rough from sitting unplayed in a case
In contrast the Strat guitar I built with 2-point Wilkinson VS100N tremolo, locking tuners, and GraphTech TUSQ XL nut returns perfectly to pitch on every single string even dive-bombing on the trem bar. That required a lot of work on the nut by making sure there was no binding (easy), carefully sanding the slots with 2000 grit until I could no longer feel the slightest friction sliding a string cut off into each slot, and finally putting lubricant for good measure. Achieving that tuning stability on a 3x3 tilted headstock design with a tremolo seems far more challenging.
So really, how stable are your tremolo-equipped PRS ? How many cents are we talking about to be deemed stable ?
