Has anybody here tried the Electro Harmonix 22 calibur amp?  Looks like a pedal, but it's actually a micro 22 watt amp head.  Looks interesting.  I was thinking it might be a possible solution for carrying powered heads/amps to gigs when you are using a pod-type set up.  Seems to get sort of dirty when cranked, but I have read a couple of reviews that says it has a lot of clean head room.
