Yep, that's another plus! They don't weigh a ton!
I know it's not *quite* the same, as an all tube head, but, it's about 90-99 percent there. Especially considering that when the sound guy won't let you turn up to get the tubes going, on a bigger wattage all tube amp, you might as well be a crappy solid state amp. A 100 watt tube amp(even a 50 watter) on three just doesn't do it.
For instance, my old JCM 900 had a sweet spot, right around seven, on the master volume. Anything below that, and it was hardly usable.
My brothers old Crate sounded better, at that volume. And those old Crate amps were horrible, for anything other than maybe metal. They did that well, though.
I can really wind up my Artist, and cook those tubes, and still not be too loud. Okay, that's enough of me salivating over my Marshall... Sorry, I just love this damn thing!
BTW- Jim Marshall has gone on record, saying that the 30 watt Artist is his favorite amp Marshall has ever made! Now THAT says something!
