High quality bass style plastic knobs. Includes 2 large and 1 small knob. 24 spline knobs fit fine spline US spec pots (ie. CTS). These knobs are compatible with ObsidianWire harnesses that use split shaft pots.
NOTE: The ObsidianWire Traditional Vintage Plus for Jazz Bass uses 1/4″ solid shaft pots and these knobs will not fit.
