It's like a sustain pedal, for zeeé guitarrrrrrrrr. The previous owner (hi Mav!) is a smart guy, so he switched the switch for a soft switch, for easy switching. As such, the asking dime is a whisker higher than a stock one, but it's worth every penny. I honestly didn't expect much trying this for the first time, but oh boy, was I surprised: this is so much fun. The absolute best ice cream headache ever.
