I just got back from Iraq, 5 years gone. now Im home. My boy (14) wanted a bass. I found a Fender p-bass I got for 100 Bucks, after stringing it up I saw the neck was bowed up. I tryed to tighten the truss rod and It poped. it was lose but I did get it to tighten. but it is still bowed ( action to high). Did I brake the truss rod? It is tight. what do I need to do? thanks for any feedback.
