Thanks all for the responses.

Im pretty sure any artist using a small amp probably does overdub layers as well as the miking the room.

If you do the same guitar part two or three times, it can get pretty gigantic.

I dont really have a good room to use. I was thinking of bringing a laptop down to a rehearsal studio nearby, using their amps and room and recording my guitars there.

Kind of a slick way to get a setup room and amp, without somebody charging you to set up, and then looking over your shoulder.

Somebody to say ok see you in a few hours!
