So far I've replaced the nut with a tusq-xl, and put an epiphone bridge on it. It seems to stay in tune better...but there is still something wrong with it. I thought it was the tuners for a while, but I'm starting to think it's the crappy neck joint. I haven't removed the neck yet, but the bolts seem small. Even with them as tight as possible, there is still some wiggle in the joint. It just doesn't feel solid. If you strike a chord, and move your body even slightly, you can hear it going out of tune.
So here's my question. Can I convert this to a "set neck" either with bolts, glue, or both? Has anyone done this before? Did it help? Keep in mind the "wood" is most likely lower quality than plywood.
