810's are no longer necessary, they haven't been in decades. But, at least here in America, consumers love to have what they don't need. Big houses, big gas guzzling trucks with giant wheels, super-sized value meals, etc. 810's will always be around, many buy them for the sound, others buy them because they look cool. 810's aren't common on the TB forum. From my observations, most people on this forum are experienced players, who know what their doing. There are several people who swear by a sealed 810 on the forum. I'm having LDS build a custom 810 for me, inspired by both the Berg NV610 and the classic Ampeg Flat Back. It's not necessary and I can easily get by with a efficient 410. I'm not buying it for the look, however. I'm buying one because I feel a sealed 810 gives me the tone I want.
