I'm at work, so I can't give the song a listen right now, but I'll give it a go when I get home this afternoon.

Does the amp have a name on it anywhere other than Peavey, or a model number somewhere? How many speakers are in it? I'm guessing it has 2-12" speaker's because of it's weight. Also, it it a tube amp or a solid state amp? Sorry for all the question, but your description of the amp has peaked my interest.
