I know I can't join the club (YET!) But last week I finally got a chance to try out the Orange AD200B and OBC 115 at the Chicago Music Exchange. WOW!! Jazzman has been pitching this rig to me ever since he got his and he wasn't kidding. I A/B'd it against every bass rig in the practice room including an Eden 300T, Ampeg B15R, Ampeg B100R and a 65 Ampeg SB-12 Portaflex. To my ears (and to that of my old guitarist who was with me), the Orange was warmer, punchier and deeper. I ran everything pretty much at noon, although we did experiment (briefly) with the cranking the gain for a dirtier sound. I tried it with a number of vintage p basses, as well as a Fender VI but thumpy bass nirvana was attained when I plugged a early 60's Hofner strung with flatwounds into the amp.
I plan to order the cabinet and see how it sounds with my V4b. I am anxious to find out how much of the goodness I heard was the head vs the cabinet.
I was very impressed.
