The guy who sold me the 73 SVT Blackline has 4 vintage straightback 810 cabs, all in various condition but all are looking pretty ratty. He is asking $1000 ea. I can take my pick if I'm interested. Having just spent $1800 on this head, I'm a little reluctant to jump right into buying one of these cabs when I can get a newer 810e or Heritage 810 for around the same price. Besides the obvious differences (4-pin speaker input, no wheels or towel rack or angled cab) are these vintage cabs that much better than the newer ones?
