Real ring modulators - new batch with artwork by Pete Fowler!
These are real analogue ring modulators, the same circuit design as used to create the original voice of the Daleks in 1963. They sound great.
The ring modulators have been made using carefully matched germanium diodes, housed in a rugged metal case. The units are 'passive', meaning they don't require batteries, but lower signal levels may require a preamp.
Connect a synth, drum machine, microphone or guitar to the input socket, a simple waveform into the 'carrier' input, and the ring modulator will produce interesting raw, metallic, robotic, bell-like sound effects. Sound files below, although I'm sure you can do better!
According to Wikipedia, the original voice of the Daleks used a 30Hz sine wave as the carrier input.
"In a 2006 BBC Radio interview, [Nicholas] Briggs said that when the BBC asked him to do the voice for the new television series, they instructed him to bring his own analogue ring modulator that he had used in the audio plays. The BBC's sound department had changed to a digital platform and could not adequately create the distinctive Dalek sound with their modern equipment."
