if you have a Titan, install it first. try it in both guitars. that could give you and idea of what's going on and where to go from there. since the AM neck was way too loose and thunderous (rather than tight), I just checked out a Titan neck to go with the Titan bridge. I like the direction Jake Bowen went with his signature DiMarzio set. if you like the Titan, but would like something just slightly more open feeling while still being very tight, check out the DiMarzio Illuminator.
