Gary, there's a lot of information already provided. I'm curious though. Are you more interested in it being a tube amp? I'd agree that if you're looking for the sound, you might want to consider Fender Mustang. There are some good settings on there! I think the sounds you're hearing are part amp, part processing/pedals, and part player! For small tube amps, I've got to say I love my Vox AC4! With a few pedals you can get all kinds of amazing sounds. Given the choices you mentioned, they all look pretty decent! Can you test them out anywhere?! Good luck!
