The SSL "FX Capacitor" is one of the oddest hardware reverb processors on the planet.

SSL is known for modifying computer chips into odd musical uses… I’ve been curious about the FX Modulator, as it applies the same concept to studio effects, using a Spin Semiconductor at its base.

The spin semiconductor fv-1 is a “complete reverb solution in a single ic” per the manufacturer’s website. How is using it for a reverb processor an “odd musical use” of a “computer chip”?

What is compelling about the FX Modulator, however, is the patch points on the dial: There’s control voltage for nearly every setting, with no menu diving, just a select dial for each effect and send any voltage or sound into three parameters and feedback inserts…I’ve never encountered a reverb unit similar to it.

It’s not that unique of a concept. The Tiptop Audio Z-DSP has a similar concept, as does the Make Noise Erbe-Verb (named after its co-developer, Tom Erbe of Soundhack fame), both of which are available in Eurorack format. The Z-DSP even uses the Spin Semiconductor FZ-1 chip, and it has been around long enough to have two hardware editions.
