Lots of better choices... I think the best choices are the Faber and Tonepros 2, both for metric. If you go with the Faber you'll need to buy adapter posts to fit. The posts aren't cheap, like $38 a pair from Faber. There are cheaper M8 adapter post choices on eBay but the fit will probably be sloppy... So, I'd go Tonepros.Is there a better bridge for this that will fit.
I have 10’s on every Gretsch I own, with the exception of my reso, acoustic & baritone. You are right; they sound great and stay in tune. My Silver Falcon came with 12’s and a few years worth of finger calluses didn’t seem to matter!My 2622 with standard tuners strung with 10s or 11s stays in tune for a long time. I can leave it in the case for a few weeks, take it out and it will either be in tune or only slightly off on a few strings.
