This Hosco 50s Vintage Fender Stratocaster Style Control Knob Set has rounded over top edges and dirt build up in the side knurls to replicate decades of use on a guitar. The knobs have a dark brown font colour and come in a complete strat set of 1 x volume and 2 x tone knobs, they will fit both metric and imperial splined potentiometers (they do not fit solid shaft pots), these use a friction fit with the potentiometer and so do not need internal splines (the same as Fender knobs).
