...and something you don't get to see too often. Here's a shot of the inside of an SX P neck. I got a wild hair in the shop and split off the fretboard of one of my necks and this is what I discovered. It should come as a comfort to SX owners and those thinking about owning one. The general construction isn't special in any way, in fact the routing is pretty rough. But the trussrod is certainly a step up from the simplest version that could have been used and IS used on a lot of much more expensive basses. This rod is actually 2 rods - a round 3/16" steel main tension rod with a threaded end. Attached to this is a 1/8" x 9/32" rectangular. This is welded to one end of the round rod and to a sliding sleeve under the adjustment nut. When the nut is tightened, it pushes against the sleeve to bend the flat bar effectively bowing the entire assembly. This counteracts the stirng tension. IMO this is a little better system because it doesn't have to crush the wood lengthwise to do it's work. It also has a bit more mass and that helps with keeping dead spots down. So, if Kurt had anything to do with it, he should get some kudo's for not going the cheapest way and still putting out the best value.
