From the post
The Ersatz Verben is a pseudo-reverb circuit using a PT2399 for short slapback delay. It was designed by FSB member CultureJam and refined by EarthTones, and based on the Crap-Fi Delay by Allesz. Delay time ranges from 40-140ms. I've laid it out for onboard pots and added polarity protection and an onboard LED resistor. Here's a demo:
