So today I ended up trading an LTD Strat, a Bugera G5 amp head & 112 cab, a Samson USB mic, and a cheap Bedell acoustic for a brand new, old stock (2013) S2 Custom 24 with possibly the most bland looking top I've ever seen on a PRS! The bland looks are probably the reason it never had sold yet. I figured it'd make a good "beater". I got a guitar that I'll use and got rid of some stuff that I wasn't using, and my dealer got rid of a new guitar that had been sitting for too long.
There is hardly any flame at all, but there is a fairly good amount of mineral streaking (I think that's what it's called) in the top, and the rosewood fretboard has a nice lighter color to it.
Before I made the deal, I worked in two new DiMarzio PAF 36th Anniversary pickups (the pre-aged version) and two new CTS push/pull pots so I can split each pickup individually and we swapped everything out for the stock stuff and then strung it up with some NYXL 11-49's.
Well, after spending a couple hours with this guitar I can safely say the the PAF 36th Ann. pickups are fantastic! I didn't really have much experience with DiMarzio's before these, having used the various PRS pickups in most of my guitars but I think the S2 pickups are definitely a place where they cut costs. This has pretty much confirmed that I will probably try other pickups in my other S2 guitars as well.
It's its the ugliest guitar I own, but it plays great and sound fantastic!
