The 1214-00 is the perfect option to upgrade the nut on your Fender Jazz style bass. It is pre-slotted for a quick and simple install. This nut is made of Tusq XL, the same material as standard Tusq but impregnated with PTFE. The lubrication from the PTFE prevents strings from binding in the slots. Tusq XL offers better tuning stability especially when using a tremolo or bending strings. Tusq XL also has more of a midrange boost as compared to Tusq. Dimensions: Length - 1.554 in.
