[sdiy] Moog guitar guts

[Veronica Merryfield]

Hey Chester et al

I haven't been able to dig anything up and what's going on with this  
yet. My patent search drew a blank so far but I wonder if it might be  
under a name other than moog which will make it harder to find.

I think you have the basic idea right. But it is the detail of the  
doohickeyness that makes all the difference.
