Recently I bought a '78 EV SRO 12" from a local fellow off of Craigslist. I haven't had the chance to play through it yet. When I went to take the stock Fender speaker out of my Hot Rod, I realized the SRO was too big (depth-wise) for the Hot Rod cab! A foolish mistake on my part, but not a damning one (in fact, a good problem to have). The "coffee can" shape would knock out the three 12AX7's. The speaker itself is in great shape for being as old as I am; the guy I bought it from is an old country slinger, a Chet Atkins-style virtuoso who has played locally in southern Maine since the 1950's. He took good care of his EV's (I couldn't buy the other one) and was the only owner. Anyway, as I wait to buy a nice 1x12 cab (probably a Lopo) for this behemoth, I was hoping to get some feedback from people who played through these or who currently play through these. I've been told that they handle volume really well, are rock-solid, and dynamic and rich. I'll try to get a picture up soon. Any thoughts?
