From the post
Designed by culturejam on FSB and CW, this is what he wrote:
Inspired by the Crap-Fi Delay by allesz, I decided to see if a similar simple circuit would work at lower delay times for reverb and slapback. It does.
Once the basic circuit was up and running, earthtones helped me refine it and make it much nicer. He's wicked smaht like that.
Delay time range is about 40ms up to about 140ms. As delay time is increased, more highs are rolled off by C4 (that was ETA's idea). So it's pretty much hiss/noise free no matter the delay time.
He posted a demo here, and it sounds pretty good to me. Something different to do with those PT2399s you've got.
Geiri's quick demo of his build:
And another clip with 100K as delay pot for longer delay times...:
