Erica Synths Black Spring Reverb Hands-On Demo

Erica Synths shared this video demo of their new Black Spring Reverb – a new Eurorack module that they say offers “a different take on spring reverberation units.”

The Black Spring Reverb features a DSP chip in the feedback path, with 7 different effects, vactrol based compressor and the option to use internal, external or combination of both spring tanks at the same time.


  • Compact spring reverberation tank to install in a skiff case
  • Manually and CV controlled feedback amount
  • Vactrol-based compressor
  • 7 distinct feedback effects
  • Selection between internal, external reverberation tanks or combination of both
  • Feedback Send and Return jack sockets

  1. This seems like a great unit, Eurorack tax makes it expensive (we have to pay more to not have a case or PSU) but I may pick one up second hand or on sale at some point, nends to be less than 200….
