I know..... I am late to the game, but I gave in and bought one used for $125. I created 3 presets that mimic my 3 live tones in 30 minutes. With my les paul treble p/u at 4 and 7 on the tone I dialed in an ACDC/ Zep 2 crunch w verb, 70's Crunch w verb and a Hair band crunch w delay. The Katana channel and master dimed and the BMT to taste and then a little mid heavy as per Johan on YouTube. I worked the volume knob for solo's and blended in the rhythm p/u for clean / cleanish grinds and such while playing along with a CD to make sure I don't get lost in the mix. I then took it to rehearsal just to see. I could easily use this as a b/u and or a real gig. I never stomped a pedal or touched my amp other than to switch between these 3 presets. I stood wireless all over the room and listened for my axe in the mix and it was present and pretty nice ( I used my tone knob when I needed a bit more cut and my volume knob to set my gain). This $200 ( new ) solid state amp with a crap speaker really covered all the classic rock bases and more. I paid more than that for a pedal or a retube on my main amp.
