SVF, freq through feedback?
How well does it work to set the frequency using the output feedback
only? Not so well it seems, as this requires fairly large dynamic
range on the pot: frequency is proportional to square root of ratio.
Overall: SVF is not so useful as a manually controlled circuit due to
the reliance on the dual antilog pot for frequency and the antilog for
resonance. Building a guitar pedal with 2 SVFs might be an
interesting project though, especially in combination with overdrive.
