I've included pictures of a few machines I built recently from some of Craig's old schematics. The 'Wooly Bear' Fuzz is based on his 'Clipping Amplifier' schematic that was included in his 'Timbre Gate' article in the April '71 Popular Electronics.
The middle machine is based on the schematic for the Group Motion 2 machine. I posted my version of the GM 1 awhile back. This is my new build of the expanded version.
The other Fuzz is based on his 'Optimum Fuzz' design from the PE-7-'72 issue.
Up next I am looking to build the 'Matrix Drums', which is the summit of what I've been working towards. I don't have all the literature on the machine, but I'm going to try to figure it out. The basic premise I understand but some mysteries remain...
If you see this Craig, let me know if you'd have any time available for an interview about your early days with Electronic Instrument design. I am working on a book about Home made electronics and music, Folk Instrument Design, and I am collecting material from a few artists whose work has meant a great deal.
Hope Yall enjoy,
