There is an Ampeg 830 in rough, but seemingly original condition on Ebay right now. Not sure about the rest of you, but I've only seen 3 or 4 of these in my life, and I grew up in NJ in the 1960s when Ampeg was the local hero.
This amp will take some serious work, but you'll have something few others have. http://www.ebay.com/itm/ampeg-bass-a...item35ccafa3fa
I'm not a collector, but if i had even a little free time I'd consider this. Has anyone ever played one that was in good working condition? Would it make an interesting amp for recording? or other use? or is its only real value as a collectible bit of history?
