I have never played a vintage AC-30 or a vintage Bassman so I don't know if either amps sound like their vintage ancestors. But, both are excellent sounding amps. If you want a vintage type Marshall tone in a relatively light weight, not too big package, the Bassman does it in spades. It has to be pretty loud to do it, but it's there. I was using an SG Standard and it just killed through the amp. A huge chunky low end. I was playing everything from classic rock to punk rock power chord type stuff. It was great. The Vox was great also. There wasn't much of a volume difference between the two amps. It has nice cleans and great overdrive. Hard to say which I liked better, but you couldn't go wrong with either amp for a classic rock machine.
