That nut was suuuuuper loose in its hole, meaning that when you went to adjust the knob bolt it would catch onto the nut and would twist the nut with the bolt, therefore it could not tighten since the nut was twisting with the bolt and on top of that, since I realized that after some twisting, it began to strip the hole in which the nut was in, therefore it went beyond any remedy

It was missing a nut and screw .please send

The only complaint that I can come up with is the "U" that holds the neck is a little big for me

Looks like sh#t.

I love the design and my T-40
