My friend recently purchased a bass for $40, and there are a number of problems with the fingerboard. First, the epoxy finish (what the person put on there before he sold it) is really uneven. Second, when I play the bass, I cannot get anything other than horrible buzzing until the seventh or so fret, and then it sounds great. I suspect it's a truss rod issue, which leads me into the third and hopefully final problem: the adjustment end of the truss rod is stripped, and I cannot use an appropriate Allen wrench to adjust. What can I do about this? BTW: We have no idea who made it, but it's a P-clone with a body-adjusted truss rod, no headstock angle (like a Fender) and a maple fingerboard. Thank you.
