Well, sort of a demo. I did not get all creative with this and mic the amp with perfect takes and edit it and all that jive - I just stuck my camcorder in front of the amp and went to town while breaking in new strings.
There's some room noise and shit., and the camcorder normalizes the audio, but I think you'll get the point anyway..
All the same channel on the amp. Just switching pickups and using the volume knob.
