WOW! If you all have never heard of/tried out one of these babies, you're really doing yourself a huge disservice!! Yes it's small in size, but that's about it! The tones you can get from this thing are simply astonishing! Even though it is a solid state amp (analog circuit) and it has switches for different settings, I would hesitate to call it a true modeling amp.
I've been looking for a nice portable amp that can primarily do clean tones very well. I have a Blues Deluxe and every amp I've tried since then has been a direct comparison to that beast of an amp. And after trying several amps since (Orange, Vox, PureSalem/SOVTEK, Hughes & Kettner), I can honestly say with all certainty that this Tech 21 beats them all. I know that's a very bold statement given the manufacturers I mentioned, but it's really true. IMO Tech 21 is a dark horse of the amp world which not many people may know about. But by all rites, they should.
So if you're looking for a totally kick-ass little amp that you can use to practice, gig, and record without breaking the bank, I would HIGHLY recommend checking one of these sweet things out.

Let me know if you have any questions about it. Thanks!
