A bit of history on Maths: the basic circuit is West Coast...but NOT Buchla. It's actually based on the Serge Universal Slope Generator and some revisions to that made by Ken Stone. Tony apparently decided that having just ONE Serge DUSG wasn't enough, so the Maths actually jams two in there...which means you have FOUR USG variants with a bunch of extra voodoo to get them pinging off of each other more easily.
