ZVEX Woolly Mammoth/ Green Ringer Two in One in 1590b

Here's a cut down version of the Woolly Mammoth (just pinch and volume controls) with a Green Ringer. Gain control has been set at maximum, and EQ control is set at 12 o'clock. I used matched 1n34a germanium diodes. Silicone gives a more aggressive octave with more ring modulator overtones. Germanium is smoother. Either is fine.

Yes, it's on two separate boards. I was trying to decide between a Woolly Mammoth and a Fuzzrite style fuzz. The Woolly Mammoth made less sense, so I went with that.
