How very much things change!

A BBD-based chorus would today be advertised as "analog" and much blather based on it not having an A-D and D-A converter. In reality both techniques will have sampling noise and heterodyning. The real digital version will have quantization noise, which can be mostly digitally suppressed.

Funny.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.

The clock looks similar to the CE-1.

Was this the beginning of "Boss FET switching"

Change this clock to a monostable configuration for the now famous and widely repeated switching.
I just designed a new fuzz circuit! It almost sounds a little different than the last fifty fuzz circuits I designed! ;)
