Hm.. the Ultra sounds alright but I'm more of a high gain amp guy, and thats why the Bravo appeals to me so much. I just posted an ad on craigslist saying that I wanted to buy one, hope it goes through. And thanks man! I've been wanting to upgrade my amp for a while but I wanted to keep it cheap, keep it tube, and keep it metal!
Actually, the Ultra's "ultra" channel is definitely high gain and metal for sure. The Ultra offers a lot more power 120 watts vs. the Bravo at 25 watts. Depends what your practice and gig situation is, but I'd actually consider the Ultra an upgrade. Also comes with a better stock speaker and available in combo configurations of 1X12, 2X12 and 4X10...or a head unit. The Bravo could use a speaker upgrade from the stock, but I've seen so many on ebay where it's already been done. The Bravo with an extension speaker cab would probably be plenty for most situations.
Good luck searching! I'll PM you if I see anything.
Here's another winner...the Triumph series...3 channel.
