Today a customer who happened to have a 70s fender strat has really bad twist in the Neck I have seen this but don't do to much with it. I have done a 80 P Bass I had the frets out and was prepping it for inlayed fret markers out of rose wood and decided to give it a twist actually heard it pop and felt it to but the end result was a straight neck then proceeded to inlay fret markers and finish the neck..this one has with a bad twist but is this a normal way to fix a twisted neck Just giving a twist by hand? like I said I have only done this once by hand is there a better way ?
