This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Ersatz Verben

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:


  1. Hi, I've just built it. It works!

  2. thanx for drawing it .... the 22u is actually 22n ... yesterday i spent 4 hour debugging it :)

  3. and if u want mor delay times .....50k on the time instade of 10k for more try 100k i have tried two of this circuit :) it sounds great .... for cutting the hiss u can play with that 22n on the ground and add more value

  4. i made this , and it sounds great :D
    tnx :)
