Having compared all 3 circuits I'm surprised so much fuss was made 
about this (especially in the Synth-DIY list) - both JH and Doepfer 
versions are copies of the same thing, with few changes, so they are 
bound to look similar. To my mind the only possible criticism that 
could be levelled at Doepfer would be for having used the _idea_ for 
making a Wasp filter clone in the first place, but since JH (to my 
knowledge) doesn't sell modules, he doesn't lose out anyway. (And the 
major 'addition' in the JH filter isn't even in the A-124.)

As they say, my 2 cents.
