I think a rackmountable terror would be good simply because people like rackmountable units for touring and because the TB heads are so light that they tend to walk when placed on top of cabinets. I know I was always terrified of mine walking off of the cabinets until good ol JMac made me a custom head shell. I really think that just making a rack mountable option would appeal to a wider demographic of players. The AD200b is actually I think only like 120 or 150 watts, so my point was to make a valve head that could possibly power 2 8x10's at 2 ohms that was closer in wattage to an SVT VR could sell well IF they made it only a few hundred more than the AD200b. Basically like an AD400b. And again, I know it goes against Orange's simplistic nature, but a head with a graphic eq or a few more features than the TB or AD have could pull in more players to the brand.
I really want to try the OBC 8x10. I have played and am about to own 2 OBC 4x10's but I know the 8x10 actually uses different (neo) speakers than the 4x10's so I was curious of the difference.
