I just got a BC Rich Revenge (with Warlock Headstock) SN: J10108----. No idea of build date; appears to be a storage locker find. Intonation is spot on, god sound but the string height is a bit too much; about 8/32". I like 4/32". I can set up Fenders all day; this is my first BC Rich. I unscrewed the Allen screws on each side of the string but the individual bridge does not go up nor down, no up or down movement at all. Any help on how to adjust string height at he brides is appreciated. Two images attached but poor quality.
