CA3401 chip - any pedal related projects use these?

[cooder]

Howdy, I've scored a bunch of NOS RCA3401 chips, are there any pedal related or otherwise interesting projects that would come in handy with these?
Cheers!

The pinout is a bit janky, so you can't use it as a drop-in replacement.

I'd say perf up a circuit with four opamp stages (or vero), and let us know how it works out!
