Modular synthesizer enthusiasts looking for an authentic spring reverb with tons of character will be impressed with the
erica synths Black Spring Reverb, a Eurorack compatible module that features a compact and skiff-case-friendly reverb tank. The module includes a vactrol-based audio compressor and a feedback send-and-return circuit for processing just the reverb.
The module has built-in feedback effects—pitch shifters, delay, ring-modulator, etc; feedback amount and effect parameters can be controlled manually and via CV, making the module an experimental instrument on its own. The module also includes an RCA send and return for connecting to an additional spring reverb tank. The module can use the internal, external or both reverb tanks simultaneously. The Black Spring Reverb includes a ribbon power cable and mounting screws.
