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:

    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

    This layout is different from 1n4001. Which one is correct?

    Recién termino de armarlo, el pedal sonaba con silbido. Le trate de buscar la vuelta hasta que me di cuenta que en la fuente estaba el problema. Porque no prueban con cambiarle el voltaje al trafo de los pedales. La verdad muy conforme

    I checked it works fine. Thanks, David. Merry Christmas.

    Very cool pedal! My tip is to put a volume control (A100K): output to terminal 3, terminal 2 to DPDT and 1 to ground.
