Here's a VERY cool pedal that everyone knows and loves. a ZVEX Woolly Mammoth! It's a versatile beast. My favorite way to use it is pushing the gate up when I'm with some noisy band and getting ridiculous. It has plenty of accessible applications and tones...but you already know that. This pedal is special because it's #35 ever built, completed on 07/26/04 from the first ever run of the Woolly Mammoth. This means that it does not have a 9v jack on it. It's 9v battery operated only. $180 shipped!
They make the ac adapters, you change out the bottom plate. I'm sure they are still around somewhere.
