My old bass player had an 810. Sounded like assbutt. Built solid but didnt have it in the tone department. Ditched it for a SVT810 classic cab that was infinately better IMO.
I know I'm about a month out on this one, but I highly recommend STAYING AWAY from Basson stuff. IMO they are some of the flattest sounding cabs on the market; they're built well but just don't have the tones. I had one for about two years and my best experience with the Basson was the day I got rid of it.
