Disclaimer: I have taken many of my basses to "professional" luthiers in the past and, more often than not, been disappointed with the results. I consider myself a handy fella and would like to learn, for myself, how to fix these types of problems. Question: I need some guidance setting up my Gibson Grabber. I went through the John Carruthers technique and found that I need to file down the nut and tweak the truss rod. However, I think the main issue is that the neck has a ski-jump in it and that needs to be sorted out before addressing the other issues. Using the pictures as a guide, any advice as to what I should tackle first?
