Kung PRS SE, you'll be using a Wilkinson roller nut or a similar design, right? From what I've gathered, the LSR is the more trusted design kaso pero Fender style nut replacement siya. Whether or not a roller nut may restrain sustain and resonance can also be affected by other factors, particularly how properly it was installed. But what I am fickle about is that installing one requires routing the fretboard. It's the main reason why I always and up opting for a Graphtech nut in the end, after considering using one.
My experience this week further reinforced the notion that the overall setup may as well be the greatest factor to consider when stabilizing tuning. My favorite guitar has locking saddles, locking tuners, Graphtech nut and string retainers, and some amount of lubricant. But the damn guitar still won't stay in tune even after a few whammy dips. So, the other day, I played with the bridge's setup a bit. The result was a huge improvement in tuning stability. It's still not as good as a Floyd, but it's as much as one would have a right to expect from a six-screw trem bridge.
