I know Mesa cabs come with vintage 30's but I have a chance to get a Marshall 1960a cab with celestion G12T-75's for a pretty good deal. My question is, are these speakers anywhere close to the vintage 30's?? Will the cab sound good through my Single Rec? I would love to get the Mesa Rec cab but money is kinda an issue, lol. Thanks, I have never heard good or bad about these G12T-75's.
