about the size of a large bar of soap, is driving two separate 16 ohm 12” speaker cabs, connected in parallel of course, and the sound is being picked up by my crappy iPad built-in mic sitting about 15 feet away. There are six or eight of these things, all but one are pretty high gain so they are what they are, pretty much one-trick-ponies. But man, what a trick. They throw off harmonics like a tube amp, they have effects loops, for the price of a pedal (this one is currently seventy bucks on Amazon). Not affiliated at all, just digging them. I have all but one. Anyhoo. Carry on.
