As for 10 Q106 oscillators; it seems like a nice round number

Regarding the PAiA 9720... Jeff at GuitarFool.com has done some really cool stuff with his 9720s. He's re-mounted them in a Dotcom quad panel onto which he's screened a redesigned graphic. He also replaced those dinky little 1/8" jacks with man-size 1/4" jacks. Check it out (2 upper left modules)...

I've got my quad panel in stock and my graphic ready to screen. I just have to work on my silkscreen technique before I give it a go.
