I've been looking for one of these for years. I was wondering if any has/had one, where can you get them, how much do they cost, and are they easy to mount. For those of you who think I'm taking like a crazed maniac a Kleen axe is a string mute. (great for two handed tap) They kind of almost look like a razor you shave with. They mount on your head stock, and you can flip it down to rest over the first fret. Last time I saw Jennifer Batten playing with Jeff Beck, she had one on her guitar. Thank you all.
