I have a Fender Jazz Bass that I have had for several years. I occasionaly perform my own adjustments to the bridge, neck, pickups, etc. to keep the instrument to my likings as well as a yearly trip to the guitar tech. I have never trusted my guitar tech, and during this most recent trip he pulled out the Fender, and took a quick glance down the neck and told me it was twisted. He also told me that there is no way to fix it, and any adjustments on the truss rod would snap the neck in two. He also informed me that the only solution is to purchase a new neck from him (of course). Question: Is a twisted neck really the kiss of death that he describes it to be? How can I tell if the neck is actually twisted? Is there a more conventional way of fixing it if it actually is twisted? Any help would be appreciated, because now I am even scared to play the thing.
