Beautiful set of buffalo nickel volume and tone control knobs to highlight your special guitar. They fit a common 6 mm knurled split potentiometer shaft and stand 5/8" high and 1" wide. They will fit flush with your guitar covering the potentiometer nut. Please check my feedback and buy with confidence. The $34.00 price is for a set of two knobs. I hand make them here in the USA. Please message me if you need them adapted to a 1/4" smooth shaft or need three knobs. I can make them with a set screw to fit a 1/4" smooth shaft.
