This might belong in a different section but the question is very straightforward. The tuning keys on a Gretsch G2202 Junior Jet bass... Would anyone be able to tell me what size they are? I don't have the bass with me to measure (NBD coming up!) and I found a good deal on a set of Hipshot Ultralites but I'm not sure if the Gretsch has 3/8" string posts or 1/2". Thanks in advance!
