I recently picked up a used Essex Traditional Series Jazz bass copy. This is a Chinese instrument that plays fairly well and sounds quite good for the money. I used it on a track a couple days ago and it recorded surprisingly well. I wanted to use it for another track tonight which was going to utilize a lot of open strings and the first couple frets when I realized it has a serious back bow in the neck causing major buzz in that position. It seems to have a truss rod that is adjustable from the headstock, but I'm not familiar with this style at all. Does anyone know about these basses and how to loosen the tension on the neck? Clockwise or counter clockwise? It seems to take an allan wrench but before I possibly strip this, I wanted to ask here. I've pulled the neck and the truss rod is only visible at the headstock, not at the end of the neck. Thanks!
