58/15LT's
In a number of threads recently it seems that there has been talk of replacing the 58/15 or 58/15LT pickups. What I think is going on here is that anyone who has been accustomed to rolling the tone and volume knobs to 10 and leaving them there for years on end will not gracefully take well to these new pickups. PRS guitars with those pickups installed are not designed to be played that way. Assuming that you already have a very good amp and your tone doesn't suck because your amp sucks, rolling the VOL & TONE knobs to 10 will give you a maximum overdrive tone (so to speak). So unless you are in a Judas Priest cover band, you will want these knobs to live around the number 7 position and only kick it into overdrive when you really need to kick it up a notch. You wouldn't want to drive all the way to Albuquerque using only the passing gear, would you? Your transmission would blow up.
Not only that, but unlike many other guitar brands out there, the 1-6 range is a useless muddy swamp. But on a new PRS guitar, the 1-6 range is actually a usable range. So IMHO, YMMV getting rid of the 58/15 or 58/15LT pickups is unthinkable.
