I know this is probably old news to the sorts of people that pay attention to such things, but [Visual Sound](http://www.visualsound.net/bbd.htm) (the makers of the excellent H2O chorus pedal) have done a large run of BBD chips that are direct pin replacements for the Panasonic MN3207 chips used in pretty much every good analog delay, flanger, and chorus pedals and rack units. They're not that expensive, either. $3.75 for the BBD and $1.95 for the clock. [Here](http://www.chipdocs.com/datasheets/datasheet-pdf/Panasonic-Matsushita/MN3207.html) is the Panasonic datasheet for the BBD chip. [Here](http://experimentalistsanonymous.com/diy/Schematics/Chorus/Zombie%20Chorus%20MN3207%20Based.jpg) is a simple chorus circuit that uses this chip. There are lots more out there that a Google search will pump out.

Nice find! Have you posted this on The Lab? I'm sure there are a few people who would be interested there.

Dagnabit, another DIY project to start...
