From the post
Mixing it up and doing Flanger Friday this week. Got a request for this circuit designed by Valve Wizard. It's unique in that it uses 2, PT2399 delay chips paired with an LFO. It features a buffered bypass, so it's not a true-bypass effect. I've also drawn up daughter boards for the bypass switching (PCB version has the footswitch board mounted). Here's the schematic for reference. You'll definitely need a 1590BB enclosure for this one.

- 1uF capacitors: one on the main board (left edge) and the one on the switch board are drawn as round cans (electrolytic); the other four are drawn as rounded boxes, taken as film/non-polar
