Pigtronix - Envelope Phaser II

I got this pedal recently and really dig it on bass. I have no real interest in reverse engineering, but maybe someone here is interested in how this thing works.

These are from my phone. So not the best, not the worst. I can get better quality later this week, if interested.

This is going to be the pedal to grab for cheap when you need vactrols...
