Edit: updated on page 8. It's not overkill. It's awesome. I've been doing my late night guitar playing/song learning with a Boss Katana Air for the last few months. The Katana is a modelling amp, the size of a radio and weighs like 2lbs. It has Bluetooth and you can stream Youtube to it to play along with backing tracks. I usually use headphones with it, but not always. Problem is, I grew really tired of the Katana's tone. It is pretty artificial and grating to me. So I set out to replace it with a real tube amp setup that would be capable of essentially doing the same thing. And I succeeded. But it took about 100lbs of crap, along with lots of cables, and the whole thing is taking up a ton of space. It will also be impossible to keep the cats off of this rig. So after a few hours playing this last night, I am thinking this is actually overkill. Something you don't ever hear me saying when it comes to guitar gear. My motto is "anything worth doing is worth overdoing". But I look at this and think "this is stupid". Yes, it works and sounds great, but... I think I'll go back to the Princeton Reverb for practice.
