Gamechanger Audio has a new product, the Light Pedal.
This has spring reverb, but instead of using a microphone to pickup the audio, it reflects infrared light from an LED off the spring. This can pickup a wider range of frequencies, harmonics, and overtones which brings a different sort of sound to the traditional spring reverb. There are also lots of controls with this so you can really tune and customize the sounds.
This video is using the Light Pedal with an electric guitar only, so you’ll have to imagine what the reverb would sound like on your favorite synth. I want to hear a better demo, and get a feel for how much range is really in this pedal.

Gamechanger is the company that did the motor synth – that made noise spinning up motors, so they’re used to thinking out of the box.
