Had a guitar that I though the truss rod was rattling. Was told by a couple guitar repair guys that it was the truss rod. The fixes for this I felt were out of my league to attempt. The Guitar sat up for over a year. Finally decided to bring it to Strange Guitar Works in New Orleans for an estimate. I was told by them it was not the truss rod and the neck just changed and it needed a fret level. This guitar played without issues with quite low action before for years. Then one day it buzzed everywhere. Well they have a Plek machine now, so it got plekked. No more buzz and quite low action. They charge $200 for a Plek, set up and strings. Anyone else been plekked.
