I'm a big Ampeg guy, I play an SVT-III Pro through two SVT-410HE's right now. I have the opportunity to buy a vintage 70's Ampeg 8x10 with all original speakers (minus one, it being replaced by ampeg) and since I've never played through one, I was wondering what the differences are between the 70's versions and the current. I have played a bunch of new 810's and I love the tone. I can't just go and try out the cab, because it's a good long drive away, so before I decide to do that, can anyone fill me in on what changes have been made, if any? Thanks a lot.
