I don't personally have one, but the guy I jam with has two, the reverb tail generator and the delay and they are built super solid like all NE stuff and the two together are a whole lot of fun. Im out of space/money at the moment or I would buy them.

They look and sound really sweet with the fact that you can swap out the firmware if you want to change things up. I have a small Rackbrute 3U that is solely a compliment to my Minibrute2 for modulation/effects/etc and think this could be a really cool addition
