Name - and tell us about - your low powered all tube amp that blows away any and all modeling. You know - the beast that would kill modeling, if you only knew how to mic and mix it correctly into your DAW.
Lots of low powered tube amps are great, but I doubt any of us has 78 of them to play with.
The problem is getting the sound of the amp pushing the speaker cabinet without alot of noise. The only real solution is to use a modeller, direct box and cab sim, or some isolation box for your amp.
I can get a decent result either way. Modelers are easier to monitor. For those that live in apartments, it's the only solution.
