[sdiy] bucket brigade circuit

[john mahoney]

Doesn't the BBD sound get worse as the clock rate decreases? That
would be pretty simple to implement.

Find a cheap old analog delay pedal and add a high value pot or
resistor in series with the existing "delay time" pot, which is really
the clock rate control.

Main drawback will be that the output is delayed from the input. You
might want the shortest BBD (fewest stages) that you can find.
Conveniently, the cheaper the pedal the shorter the BBD will likely
be.
