Dan Armstrong Original Green Ringer Guitar Effects Module

If a single note is played into the Dan Armstrong Green Ringer, the pedal 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 Green Ringer effects module produces will be harmonically related to the original notes (such as sub octaves) or dissonant. The Green Ringer gives the musician much better control over the effect produced than a conventional ring modulator, since he or she is no longer playing against an arbitrary modulator frequency. It features Input Impedance of 100 k Ohms. Has Output Impedance of 500 ohms, and a Signal-to-Noise ratio of 86 db.
