Hi folks, just picked up my 5120 from a local luthier, installed some HS Filtertrons I had in another guitar and cut me a new bone nut. I'd already put a brass Compton on there. He did some really tidy work, the guitar plays very nicely (and sounds great!). What I can't get over is the difference with the Bigsby. Was just playing the guitar for a few hours, quite forcefully wangin' away at times too, and it just wouldn't go out of tune. Amazing, it's so good, feels like a different guitar! The combination of the new bone nut, the brass Compton and the pickup swap is just fantastic, I'm a very happy camper right now!
