I'm currently working on a 360/12 V64 (from 1993), and suspected a truss rod problem.
I managed to remove them and was stunned that they are bent this much, I thought they'd be straight?
The thread end of one rod is bent and at the neck heel, the nut pocket has crumbled wood, therefore the rod was pulled towards the head more than it should (hence I found an added spacer nut under the normal nut at the head end.
Without strings and rods, the neck is *almost* straight, a little bit of bow is still present. I wonder if it would respond to heat treatment? A local luthier has such a device...
Probably the luthier needs to do some work on the rod pocket at the heel to rebuild the crumbled wood...
I ordered a set of new truss rods and hope I can get the neck set properly, with the straight rods.
Cheers,
Jeffrey
