Last week I noticed a bow in the neck of my jazz. I figured i would adjust the truss rod and get it back into playing shape. well, the truss rod wouldn't budge... so, off to the tech to see if he could work his magic. He tried for a few minutes, but to no avail, the truss rod was maxed out. The Jazz was cheap bass that was modded out and essentially a beater bass,but still, I played that bass more than all my other basses combined. my tech offered to order a mexican fender neck for me but, the body is just laminate and not worth it, even with the upgrades done to my bass. I guess it's time for a new bass.
