I feel dumb for even having to ask about this, since I should be able to figure it out myself ... but I've done all the troubleshooting I can think of (I'm definitely not a tech) and can't seem to find a google-based answer. I hope this is the right place to ask this, also. Guitar : 2000 Ibanez RG7420 7 string with tremol-no installed. Situation : The slightest pressure against the back or front of the neck causes the guitar to go really sharp or really flat. I can see the string height change as the neck bends... It never kept tuning really super well, but lately I have to be super careful how I play it so it doesn't go sharp/flat while I'm chugging away. It's tuned b/e/a/d/g/b/e -- D'addario string 9-42 set + 56 If I strike the low B string (normal strength) and press very lightly on the back of the neck, or very lightly on the front of the head stock, it goes way out... it does correct itself. Troubleshooting I've done : There were 2 neck bolt/screws that just sorta spun (I believe they were stripped), so I took the neck off and added some wood glue and toothpicks and put it back on. I've tightened anything else that was loose. I checked to see if it was the bridge that was moving, nope. Everything else seems to be fine. I keep my basement warm and at 40% humidity. I know that necks move if you really pull or push on them, but this seems WAY to sensitive to me. Any thoughts would be greatly appreciated. Could it be related to the tremol-no? Do I need to dowl-and-re-drill the neck bolt holes? Thanks! Cheers!
