[octatonic]

I have a few:

'62 Fender Bassman
Fender Prosonic
Mesa Dual Rectifier
Marshall JCM800 and JCM900
Fender Blues Junior

They all have their sound- there isn't a particular one right for any situation.
Mics could be anything really- M201, E609/906, RE20, Josephson C42, Earthworks SR30, D112, 57's. Again, it really depends.

I have a distro box that allows me to sent to multiple amps at once- creating a huge wall o synth and then micing the room sometimes gives good results.
