This is the one Gordon uses (along with the meatball). I actually use it on guitar and its the best envelope filter I have ever played. Many options and you can preset them as well. I just need the money for the tour about to start! $175 paypal'd and shipped. Or pick up in Saratoga Saturday!!

Bump price drop
Still selling this? I've sent it to my bassist in our band in the event he's interested.
I sold it already. Sorry
