I am a retired, 58yo home studio enthusiast. I have a JTV 69S Variax, and I have an issue regarding my first string replacement. I removed all the old strings, and right away things went south. The nut fell off, as did the bridge, hanging only by the wiring. One this happened, of course the whammy springs fell out and were a beast getting the first string attached while holding the springs in place. After getting all the strings loaded, the nut remains loosely in place and moves when I bend any string. This isn't my first rodeo, but I felt like an idiot having such a hard time with such a simple issue. It was utter madness getting to this point. First dumb question- shouldn't the nut be fixed in place? Glue? and if so, what kind is best? Second- after the change I noticed the whammy bar is quite low to the body. I don't know if this is something I hadn't noticed before the change. Any help and advice would be greatly appreciated. My head of grey hair seems even more grey now.
