Hello all, First post. Just bought my first Gretsch. If not against forum rules, I'll post a link to my thoughts over on TDPRI, should give you a sense of what I think of this guitar and what I compared it to when I bought it. TDPRI link tl;dr: this guitar is amazing -- questions below! Lots of good info on the forum about this guitar! I adore the BT pups. The FT were good too, I was probably 50/50 on a 5237 as well, but the balance on a strap felt better on a 5220 to me. The BT pups in these are real, real sweet. What I'd like to do is - replace the tuners with something better (these don't feel very accurate) - replace the output jack with a real one (this one looks and feels like a paper clip, you don't get that solid "snick" when you plug in) - master volume pot isn't to my taste, currently it is a "linear" B500k, would like to try an A500k log/audio pot in there to get more control over the range - same with master tone pot... - I've seen several people talk about a new bridge... is that really necessary? QUESTION 1 For the tuners, specifically, I want to make sure I'm not just doing a sideways replacement. I want better tuners. Since I don't know exactly what is OEM (they "look" like unbranded Grovers but they don't feel very accurate), if anyone has any insight I would appreciate it. I'm thinking these; they look like drop-in replacements to me: Grover 305 Rotomatic QUESTION 2 Also, bridges... is there something inadequate with the OEM tune-o-matic type? I've seen some of these thrown around. What improvement(s) does this give? Graph Tech Resomax Tune-O-Matic Thanks in advance!
