R.A.Moog Modular old school ring modulator demo.

Demo of a DIY discrete ring modulator on a R.A.Moog Modular. The only sound sources are the two 901 oscillators ring modulating each other. All sound is from the ring modulator output then through the 904A filter, 902 VCA. There are many ways to patch, but this is just demonstrating what the discrete ring modulator sounds like with a pair of the various 901 oscillator waveforms..

While the sound of a ring modulator is usually associated with bell like tones, this type can get a sort of chorus effect when the two inputs are close in tune. At times, this configuration with the low output 901 oscillators, has some really nice sounding tones similar to the Minimoog.
The module is DIY and built to 1969 R.A.Moog modular specs, using mostly period correct parts. Germanium transistors are matched and the transformers are Edcore with 20-20,000 Hz frequency response. Not many effects can improve on the tone of the old 901 oscillators, but this ring modulator seems to take the 901's tone and multiply it.
