This is dated 8-31-04 so is an earlier one without LED or AC power option. It is in perfect condition and works excellent. It comes with original manual, Box, and red shop rag wrapped around it. I don't find much use for it and always go back to my Green Russian Big Muff for distortion and have a Pickle Pie B coming so need to make room. I am asking $250 shipped, paypal is ok. more info can be found here: http://www.zvex.com/mammoth.html Feel free to ask questions.
