I've had my MIM Jazz Bass for about 3 years now. I've always played with super high action because I like to dig in a lot (probably too much). That brings me to my dilemma. This neck has always had a whole lot of concavity to it, the better to increase the action height. When I finally got decided to straighten it out a little, none of my allen wrenches would fit. I got to looking at the end of the truss rod, and it looks like it might be stripped. Whereas I can clearly see the hex outline on one of my other basses, this one looks like it has been rounded off. I've stared at it and stared at it, but I just can't tell for sure. Does one of these look stripped/rounded off to you? The left pic is my J-Bass, and the other is a Cort Freedom Bass that looks like I think the Jazz should. Call me crazy if I am, please.
