Folks, I built a Precision Kits arch top a few months back. It turned out great, and I was very happy with the final product. When I first set it up it didn't seem to need any truss rod adjustment. I just strung it up with 11-49s, dropped the bridge to an appropriate level of action, and it surprisingly had exactly the correct amount of neck bow. A few months in, my action has been getting higher. I'm adjusting the rod, and can't get rid of the current excessive neck bow. The rod is as tight as it wants to go without risking damage. The bow starts at the edge of the neck heel, and it seems to climb up from the heel to the last fret. I fear that letting it sit with a truss rod that was apparently too loose may have distorted the shape of my neck. Either that, or the truss rod was not properly installed. I've never heard of a PGK with a bad truss rod installation, so I'm assuming this is my fault somehow. Any suggestions on how to deal with this?
