A friend of mine gave me his old Fender flats envelopes/strings from most likely the mid-late 60's (for his bought new '66 P). Just thought I'd share pics of this piece of Fender history. (he only had 3 of the 4 - no G) Don't forget - clean strings sound better, look better! The red ones are BIG! (8.5" square), and the others are same size as current packaging.
