Hey guys, I'm looking for a super long shot. Im trying to track down Signature series #521, it should be an 1989. The guitar would be my birthday guitar 5/21/89. Unfortunately I know nothing about it or where to even start looking, so I'm coming to you! Im hoping someone here either owns it, or knows who does, or even has seen it somewhere. I can't find anything online, and Facebook groups are bringing me nothing. So, help me PRS forums, you're my only hope!
