First off, let me apologize if this is the wrong section (and any mod is of course welcome to move it). I love this bass. Love love love it. Out of all of the basses I've owned over time, I had no idea that such a cheap, simple little short scale would fit me like a glove. Anyway, fapping over it aside there's two things I want to do with it: 1. Replace the mini humbucker. Sounds fine-ish as is, but this is my baby at this point and I want to give it the finest silks, so to speak. For the life of me, I cannot find much information on bass mini humbuckers made by third parties, let alone anything on whether they'd fit this Gretsch. Routing issues are, hopefully avoidable, but I'm not scared of them. Just don't want to throw a hummer or whatever in there because I'm digging the mini sound in general. 2. Replace the tuning keys. Not the tuners, just the buttons. Cheapo tuners, I'm sure, but they hold tune just fine and there's none of that looseness that requires you to downtune and then to back up to keep it tight. This, of course, is a purely cosmetic thing. I'm giving it king of a makeover with a mixture of black, chrome and pearloid. Just not sure where to go to find bass tuning buttons -- or how to tell if they'll fit. Thanks so much ahead of time.
