Position I illustrates the normal position of an ideally tuned Floyd Rose bridge. The bridge (orange) balances on a pivot point, being pulled counter-clockwise by the strings' tension and clockwise by typically one to five springs. Controlled by special tuning screws (purple), these two forces are balanced such that the bridge's surface is parallel to the guitar body (olive). The strings are locked tightly with a special mechanism at the nut (green) as well as at the bridge (turquoise), hence "double-locking".
