1 Cowgirl 1 year ago I had a couple of early electromatics. A 5120, and a duo jet. First up, the newer electromatics look fantastic, they really upped their game since the early ones. I was wondering if they have fixed their old problem. Getting one to stay in tune. The old ones, I would replace the nut, put on my fave vintage style tuners- Grover stay-tite. And even went as far as putting on a USA bigsby. They just did not stay in tune. I'm thinking of buying another- they look so sharp these days. Any tuning problems not fixed with a new nut?
