Outstanding addition to your guitar. Cross pistol volume and tone control knobs smaller foot print 5/8" wide and 3/4"high. The price is for a set of two knobs.They will fit a 6 mm knurled split potentiometer shaft I also can adapt them to fit a 1/4" smooth shaft. I hand make them in the USA. Truly unique and an upgrade that will turn heads. Please check my feedback and buy with confidence. Please message me if you need three.
