My Foundation is a bit neck heavy. Not as bad as a BC Rich, but enough that I'd like to fix it. I'm already using a rough leather strap, and it's not quite enough. It keeps it from really sliding, but you can still feel that it wants to. Would I be better off going with some of the ultra light tuners or a really heavy bridge (or both)? If both, I'm only going to be able to afford one at a time, so which would be the most effective?
