I'm fascinated by the new modeling stuff, and I will eventually get something from Line 6 or whoever so I can play around. That is, use it as a fun distraction. But what I really, really want in a piece of amplification gear is that it NOT have bluetooth, 47 models of Marshall stacks, and all of that. I want to plug it into a wall, plug a cable into it, and focus on making music. I want the amp to be a part of the instrument, not one more piece of tech that has me staring at a computer screen, hunting around for a special cable, lusting after the new version, and so on. It's really only somewhat about the sound (though my new, hand-made, Allen Accomplice does SOUND great!). It's also about the experience of using it in the real world and my relationship to it as a musician. So in that sense, being obsolete or not obsolete is beside the point. Is a violin "obsolete"? A grand piano? You can replicate the sound pretty well through high end keyboards and a good PA. But it's somehow not about that.
