Maybe this is why the bassballs sounds pretty cool too. It's also a wonder
in the minimal, economical area. With a crude half wave rectifier,
apparrently controlling the current through transistors to alter the cutoff
frequency of a multiple feedback lowpass filter. ( At least that's what I
can remember from when I had to trace a circuit of a friends broken unit.
Bizzaro design.
