It might be thinner, but unless someone had it refinished in nitro before you got it, it's a poly finish.
Most PRS guitars are poly finished, it's something that most people won't pay for, so guitar companies don't want to increase costs for effectively no reason at all.
The whole nitro Vs. poly tone debate is bull#### i think, i've painted alot of things before now, and i've played and took guitars apart since about 1994 when i was 14, for badass tone in any electric, pickups and electronics will give you the most tonal differences, then strings, then woods.
The amount or type of clearcoat is a non issue, you want it clear, and you want it tough, poly for the win.
If you went to PRS for a guitar, and they said do you want it with a hard finish or do you want it with a softer finish, which you gonna pick?
Even if they were the same price you'd pick the poly one right? Or am i wrong?
Anyone else got a view on this?
