I received an ebony Epiphone hummingbird today from Musicians Friend. I initially noted a more or less quarter size dent on the lower bout and called them. They were nice and offered me a $25 credit, I said $30 & they were fine with that. After I calmed down, I saw a sticker on the back of the headstock. It makes me wonder? My guess it means it has a/some issue but is not to be thrownaway. Cosmetic only? I would appreciate any insight. I paid $299 to my door minus the $30 puts me at $269. Guitar sounds great.
