In the past I never gave it much thought, until the other day while cleaning my bass. What IS the deal with the "Skunk Stripe" (that dark piece of wood running down the back of the neck)? Both of my new Standard Jazzes have them (not complaining, kinda like the way it looks). I have read all sorts of stuff here and even on the Fender Forum, with no real answer. Does anyone know the real LOW Down?? Are they dropping in the truss rod from behind (even my Strat Standard has one) like the old days, or is it just for looks??
