These knobs are from "JAT Custom Guitar Parts". Search in Facebook and Instagram to see more pictures and new parts daily. These knobs fit most amps, Effects 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 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

JAT...
