I've been playing this EB-3 copy that belongs to a buddy of mine. He got it from his uncle and doesn't know what the strings are. I really like them and want to find out what brand and type they are. They look like flats, and and feel like them. The sound is flat-like, but with this nice round-like growl and clarity when you pop, dig in or use a pick. I think they may be halfrounds but they're definitely not daddario flats. Any ideas? hope the pictures help.
