Shadow SH124-25B Kill Pot 25KOhm lin.

The SH 124 Kill Pot is a unique potentiometer with a momentary push
switch for electric guitars. It momentarily kills the sound by pushing
it down and automatically springs back when released. This can be used
create extraordinary machine gun sound effects, or other rhythmic
muting without sacrificing the life of your toggle switch. You can
install the SH 124 Kill Pot easily in any common electric guitar, and
because of its 16 mm bushing it even suits arch-top guitars like
Les-Pauls. The SH 124 replaces either the standard volume or tone
potentiometer of your electric guitar but still functions as a
standard potentiometer so you do not lose any control.
