Sorry to go back on topic..

.. but over here in the UK, Blackstar amps are immensely popular, as much as Fender or Marshall. Their valve amps are terrific. However, I'd also be skeptical about the system for emulating tubes.
Every amp maker is always saying they've done it, but they never sound as good. Peavey had/have a system called TransTube, but they never sound, or act the same as valve amps.
The only advantage of the Blackstar is that it'll be a properly loud 60 watts! And it'll probably be better than a normal Solid state amp.
Finally, I have to say blackstar aren't my cup of tea at all - they're geared for high gain and rock and metal. I prefer a bluesy sound, just a bit of crunch, and they just don't do it as well as others. (All my opinion of course!)
