Yeah the duncan convertibles were awesome amps and completely ahead of their time. I just saw a combo in a store or like 400 bucks. I wonder if I should snatch it up. Can you still get the modules or whatever for them?
I played a SD combo a few times and it was as inconsistent as my Laney AOR50. It wouldn't sound the same for more than 15 minutes, so you were constantly fiddling with the controls trying to dial it in.
