^ (dmoney) yeah i mean i tried the avenger ages back, and while the jet city isn't as good, it's in the ballpark. you'd know it was based on a soldano, kind of thing. the jet city doesn't have the depth mod... there's a dearer one but i haven't tried it. And yeah, i mean you can obviously alter the tone etc. to a certain extent, but i just mean that the vibe it gives off without some tweaking is pretty 80s- it's pretty bright (though it's a lot smoother and more refined than a hot-rod marshall type of thing- it has one foot into the more modern high gain camp, kind of thing).
Also check my edit in the above post, i edited in some more info about blackstar for you. :)
^ versatility is the problem. You can dial in a sorta dirty clean type tone on the normal channel, but it's not amazing. i guess you could play classic rock ok, but it's not its forte.
it's versatile in that it can do hard rock through to modern metal, but it doesn't have great cleans and the lower gain drive tones can be a bit thin.
as i said, some of the other ones (allegedly) do the lower gain thing a bit better, but then (also allegedly, as i said, i haven't tried them) they don't seem to have the high gain capability the jca50 and 100 have.
actually... what might be worth pointing out is, if the Jet City is well under budget (and sounds as good to you as the dearer high gain amps), it might be an idea to look at some other amps as well. For example, combine the jet city with a fender blues junior or peavey classic 30 or traynor ycv40/50 or something like that (or a clone of a marshall 18 watter or fender deluxe or something like that- as far as i'm aware there are several good value companies in the US making amps like that, though I haven't tried them so have no idea what they're like). Even super expensive multichannel superamps like the bogner ecstacy and engl se rarely do everything perfectly, because there are so many differences between different amp designs (not to mention cab and speaker design)- often two good amps aimed specifically at the tones you want will do those tones better than a much more expensive multichannel superamp will. So that's worth bearing in mind, I think.
