Our Emerson Pro split shaft pots are made to fit USA Spec 24 spline push-on knobs. Some USA & Import Guitars will need new USA Spec Knobs as even some US makers use import spec parts which will not work with our pots. We recommend that you don't rush the knob install process. If your knob is too tight and is not going on ,slightly crimp together the top of the potentiometers shaft ever so slightly so that when you go to push on the knob you don't damage the pot shaft by exerting too much downward pressure.
