These knobs are from "JAT Custom Guitar Parts". Search in Facebook and Instagram to see more pictures and new parts daily. These knobs have a set screw and will fit most amps, pedals and guitars with smooth shaft pots. If the knobs don't fit, send them back and I will refund your money or send you the knobs that will fit. I can also customize knobs to match any amp, pedal or guitar colors or color schemes. Let me know if you need more or less than what is listed and I will post them for you. Message me for custom orders.. let me know if you have any questions.. Thanks
