ElectroKraft Ring Modulator + Low Bandpass Filter:
Metallic, clanging noises. You can produce robot-like vocals, spacey sci-fi sounds, metallic distortion/fuzz. I added a low bandpass filter to allow onboard control of the input frequencies. You can produce a whole host of sounds with one of these depending on what you use as the input sources. It requires 2 input sources and has one output. Use guitar and synth, guitar and bass, bass and keyboard or microphone and synth. A well known effect in the experimental music realm. Used by bands such as Sonic Youth. This is a passive device, requires no power source. The frequencies are determined by the 2 input sources.
I have loved this unit, and hate to see it go, but it needs a new home. This is your chance to own the real thing! on ebay!"
