My good friend (and co-worker at a music high school in Sweden) Christoffer Wadensten [ www.meadows.se ] and I did the first jam! Another friend (and co-worker), Marcus Måttgård [ http://www.youtube.com/user/MarQTwang ] filmed it using my iPhone 4! The UBass sounds really great. And it’s recorded with just the built-in iPhone 4 mic!!!
Play UBass! 
Yeah! That’s a good jam!
