While I was doing a string change on my '95 CU24, I pulled the pups to see what was written in the cavity. This is the bridge cavity. Looks like the guitar was originally part of a giveaway. I'm not sure what G. P. is but it may be Guitar Player mag??? Joe Knaggs last name. The "10" makes me think it's a 10 top, but there is no 10 on the back of the headstock.
