I just picked one up today, and it sounds great! However, I'd like some information from any Sunn geeks out there. I've seen what looks like a couple of different versions of the Beta Bass combo online, one with a smaller slot port across the bottom of the cab and one with a larger port with a vertical divider in the center. Mine is the one with the smaller port and the baffle on mine is black as opposed to the white baffle I've seen on most betas. It looks like this except with a black baffle. http://sunn.ampage.org/site/museum/betabass/IMG_0002a.JPG Anyone have any idea about what this says about the combo as far as when it was made? I've done some searching, but couldn't find anything. Thanks for the help!
