4 New Black Electric Guitar Speed Knobs Les Paul Abalone Blue Green B-Stock Product Description: These are B-Stock or "factory seconds". There may be slight imperfections in the finish of the knobs. Color: Black with abalone circle, white numbers 1-10. There is a lot of variation in the color of the abalone ring. It may not match the pictures. This is a coarse splined set of knobs. If you count the splines on a coarse knob you will have a total of 18 splines.  When you count them on the pot, there are 8 on each side of the split (16 total). Almost all press-on knobs that fit coarse 18-spline pot shafts won't fit fine 24-spline shafts, and vice versa. NEVER pinch the control shaft with pliers to make a knob fit. This can cause the split shaft to break. Material: Plastic Fits for Gibson or Epiphone Les Pauls , SG and other Similar Guitars which have 6mm diameter pots　 Package includes: Speed Knobs x4 These are factory parts. Instructions are not included. If you have any doubt about installation, consult your local luthier.
