I bought this just a couple of weeks ago for a very specific thing and its not quite what I need but this pedal is a unique & limitlessly creative tool - check the description & also the video below as it's a really good demonstration video!

Excellent condition - just a couple of fine cosmetic scratches on the base from previous owner.
