I mean I can screw a post into the bushing from either side of the bushing. Set screw? You mean like you thought up for Edge Pro's? I considered that. For one, the threads are finer on these posts and is a skinner post than Ibanez', so finding one?? Your idea kicks ass, don't get me wrong but what I gathered from reading about it there is some trial and error in setting it at the right position, while adjusting post height for action. With my guitar butchering way I could just screw the rear post in once after I've adjusted the action. I guess I just like things to be overly complicated. Kind of a challenge, you know?
