Going to zero, eh. That, I did not know! I did use the Moog FFB on Moogs
(model 12 & 15) and I really did like it, and I know others on this list do
as well.

How steep are the Moog's? Didn't they use LC filters or something equally
strange?

Thanks! I'll take a look! As I said, this has been brought up on the list
before, so if MOTM builds one, we will buy!
And I'd like to second Bradley's welcome to you Juergen, your designs have
been really well received here!
