WD Green Ringer - 1980's reissue of the iconic Dan Armstrong Green Ringer

This is a used W.D Electronics 1980's reissue of the Dan Armstrong Green Ringer. Tested and works great. Includes original instructions.

A very interesting and unique type of distortion device which produces ring modulation type effects. If a single note is played into the Ringer it will produce a second tone one octave above the original note, but if two notes are played into it, it will produce sum and different tones just like a ring modulator.

Depending on the musical interval between the two notes, the additional tones the Ringer Produces will be harmonically related to the original notes (such as suboctaves) or dissonant. The Ringer gives the musician much better control over the effect produced than a conventional ring modulator, however, since he is no longer playing against an arbitrary modulator frequency. The Ringer features an input Impedance of 100kOhms. Output Impedance of 500 ohms, and a Signal-to-Noise ratio of 86db.

Configured to plug directly into a guitar but can be rewired to plug into an amp.
