That all makes sense. I think with the acoustic because the strings are thicker there is a lot more slack since they come higher out of the bridge, so I've never really thought about it when I just pull it loosely through the hole, and by the time it is wound tight there are already a couple of turns around the post.
With this one I guess I just pulled it through too much. I suppose this is also what the floyd rose is for, because it all gets locked in and can't go anywhere. I wouldn't mind building the SV-1L at some point, but I think the next one I can justify is a bass, because at least then I have one of each type of instrument.
