First of all, I will address the access to the
truss rod nut. This is my solution to the problem. I cut a 4 mm allen wrench to 1/2 inch long and that solved my problem. Here is a photo.
Now for the
truss rod adjustment. I have found a couple of my G&Ls that seemed to be at the end of
adjustment. In both cases I found the
Adjustment nut not threaded deep enough. I replaced the nut with one threaded deeper or you can make washers and put under the nut. I received new nuts from G&L that worked just fine as they were threaded much deeper. I would check that before doing anything else. It completely solved my issues. I have not had a bad G&L neck yet. My Fenders are bi directional
truss rods and there is no easy solution for that. Just my experience. Have a great day tomorrow everyone! Thanks-- Darwin
