[sdiy] Moog ladder (Re: making 2 or 3 dollars an hour...)

[Bob Weigel]

The parts layout was exactly the same on the Sh3 and apparently Moog 
complained and that's why they released the SH3a which has the other 
filter design.   It's interesting to note that pretty much the same 
designs appear in the early Crumar brass products, (Multiman, Performer 
A rev, Orchestrator) and also the Russian Aelita and probably others.  
And of course ARP tried to pot theirs and Moog discovered that what was 
in there was an infringement and they asked them to stop and they did.  
Pro-soloist, early Odysseys etc.  -Bob
