1 tutu10 2 weeks ago Hello Gretsch lovers. I wanted to talk about the comments I have seen regarding tuning issues, requiring the Gretsch player to scramble around changing the nut, upgrading the Bigsby, and getting expensive locking tuners. I've owned a 5122 for 2 years, and never had one issue of it not staying in tune. After all the comments I've read here, I thought that perhaps I got lucky, but I've had my new 5420 for a few weeks, and it stays in perfect tune just like my 5122 always has. I don't get what the issues are. Did I get lucky twice? Are the tuning issues possibly from players who don't do their bends properly, or don't put strings on the right way, causing tuning to be problematic? I plan to do complete upgrades to my line of 5420 guitars, and installing new locking tuners is on the agenda, but to be 100% honest, it doesn't seem necessary.
