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:

  7. 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

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