That is a great mod! It certainly adds depth to the chorus. I wonder
if we can source some of the better BBD chips with 2048 stages instead
of 256, because that would probably make your feedback mod work even
better.

And, I think you need to work out what the minimum resistance should
be before you swamp the input because the sweat spot is probably very
close to the point at which the circuit gets swamped. You can clearly
hear it in your sample.
