Hello. I've had to adjust the truss rod on my 12-year-old MIM jazz bass constantly for a long time. Pretty much ever since I got it. It's especially bad when the seasons change, but I keep an allen wrench with me at all times to make adjustments as needed. Sometimes every time I play. I have a luthier friend who, when I explained the situation to him, said "some necks are just like that". So, what should I do? I mean, I could just deal with it and make the constant adjustments like I always have. But is the ultimate fix just going to be a new neck? My impression is that I just got unlucky and have a lame ass piece of wood for a neck.
