These are used in the very popular Soundcraft EPM mixers and possibly some of the others but I have not been able to check
( I have been advised these are also used on the EFX range )
These are the genuine Soundcraft one not clones from other mixers or other manufacturer that "look"the same.
These are dual cast plastic manufactured
I have listed fader caps and other parts on separate listings
Price for one knob discount for bigger quantities, some colours are rarer than others
