I had one, it was stolen. a good head, pretty loud with a 115. from '72 or so I believe. had a nice distortion control. I would get it you will like it, though it depends what you are trading for it...
I own a Peavey Century, but might not be the same one. Mine has pre & post gain so it makes a great guitar amp as well as a bass amp. With full bass & treble, I get great sound. I also like the pre out so I can drive an additional amp. I'm using a Crate Vintage 50 watt tube amp along with the Century on a full stack of 8 12"s. The Peavey on the bottom cab gives bass & punch, and the Crate tube amp gives great color and brightness. Both amps together sound like a bunch of Marshalls playing at the same time. I absolutely love it. I also bridge the Peavey to a Sunn Coliseum 300 watt bass amp into a 18" folded horn cab. It sounds so much better than just the Sunn alone. The preamp in the Peavey is perfect with no hum. I'll own the Peavey until the day I die.
