Firstly, apologies for the out of tune guitar at 1:42. I was bending over and bent the neck, you see.. :)
Aside from that - how is this thing? I mean, how cool is it? In a 200gm pedal? Whoa! Coolness.
There is no literature on the Tube Cake as yet, as far as I can see. It was literally handed to me at the recent Frankfurt show by my friend Sergey (whose English is much better than my Russian..) and I think this one is a prototype. But more info and specs will be coming shortly and you should watch the AMT sites.
AMT Electronics - V. Kampf, A. Chernyaev and S. Marichev - have done it again. More demos of this little beastie shortly.
Cheers,
BK
