Pearl PH-03 Phaser

[hobbyseason]

I played one of these recently and it may have been my favourite ever phaser. Particularly using the manual  control to find the sweet spot for any sound.

It'd be a big one, but i imagine it'd be doable with a couple of quad op amps?

Big thanks in advance to anyone keen to do a layout
