Ive had my silver sky since April. The volume knobs numbers are worn off and the bridge seems like it has started to rust? It's either some dirt ingrained or sweat oxidizing the metal? Has anyone else had any of these issues? Ive been playing it mainly, using it for gigs. Sweating like crazy durring the gigs lol These should be covered by warranty , I mean 2200 USD and a month later this happens? I expected superior quality from PRS but was not impressred by the guitar knobs, bridge seems great expect for the rusting or maybe my mistake of somehow using my palm to dig dirt into it???
