This is a bigger, fatter version of the Black 1510 knob. Now with more to love.
These durable knobs come with a set screw and are built for 1/4" shafts.
A black metal flat head set screw holds everything firmly in place.
Not only do they work on pedals but on amps and guitars too.
They fit like a glove on 1/4" smooth shaft pots.
