It's a Sarno Music Solutions Earth Drive. I've been trying to recover from the fact that my Lexicon G2 completely crapped out about 6 months ago. So, after dealing with other multi-effects, I decided to try out some stompboxes. This is pretty cool, in that it does overdrive, but doesn't sound as generic as a Tube Screamer. I've also recently gotten a Groove Regulator envelope filter. It's got an effects loop built in so I can filter the overdrive, but still have a clean control signal hitting the filter. It's pretty cool. I still haven't worked out delays, choruses, reverbs, etc. Lexicon had me pretty spoiled.
