These heavy chrome plated knobs are appropriate in style for early to mid '50s Teles, Esquire, Broadcaster, NoCaster and even some old Fender steel guitars but they'll look boss on later Fenders too. More rounded dome top than current Fender chrome dome knobs; some builders think that the Ernie Ball is closer to the look of the old 'black guards'. Medium knurling on side, set screw type for fixing to standard USA 1/4" solid shaft pots. Ernie Ball includes allen head set screws. UPC 749699163541.
