I'd do just the bridge if it's that big of a problem. Have you just tried some Loc Tite to see if those screws stop turning. That's a cheap fix. I've left mine stock except for a chrome HB mounting ring. I'm not a big fan of the round knob to change pickup selection, but I can certainly live with it. I think the thing pretty much rocks hard just the way it is.

Still, you really should get the Charvel.
