That's a pretty rare gem. I think I had a bass amp from that line go through my hands a long time ago.
The angled baffle is an interesting idea you don't see on other amps. I wonder how the sound waves are shaped, having two speakers angled in like that.
Does it sound like their idea works, or does it sound odd in any way?
Hows it take pedals?
I think it was the '78 Beta Lead that Slash cut his teeth on.
