I don't know anything about these amps. After a google search I get the impression that there's a niche group that loves them. This is a bass amp, which is kind of what I'm looking for right now. Josh Homme, in his Kyuss days in particular, played guitar through vintage ampegs and bassmans (bassmen?) and had killer tone. So my questions are:

Does anybody know anything about this particular model?
Is this a good deal?
Anything I should look for when I go check it out?
How's it sound through a modern guitar cab?
Any proud Valco owners who wish to sing their praises?

I'm gonna go try this thing out. Any info though would be great because this thing really has a sexy vibe (to my eyes, and I hope my ears) but I just know nothing about it.
