An excellent alternative to PRS lampshade knobs, our 11 sided Tapered Knob (11-T) is similar in oversize and shape but the 11sided facets do provide the player with a little more grip. Each knob passes through the hands of luthier John and they are found on the finest of custom boutique buillders and Private Stock PRS guitars alike - they are very fine knobs for the worlds best carve top electric guitars.
