"SERIAL#2873Moog Taurus Description:
The Taurus is a specialized monophonic bass synthesizer using two audio oscillators with glide, two contour generators, and a VCA, coupled with the famous 24 db Moog low pass filter. The Taurus has three programmed voices and a voice that you can design from scratch. The Taurus is a variable synthesizer that features two audio oscillators to create phasing effects, parallel intervals, and rich percussion sounds. In addition, functions like glide, decay and pedalboard octave may be switched by foot during performance. And its five octave range makes Taurus more than a bass instrument. Of the 3 models of the Taurus Bass Pedal Synthesizers made by Moog, the Model 1 is considered to be the most desirable. It sounds fatter and has more presence than version 2 and 3 [anyone know more about this 3rd model?]. It was nicknamed the Mini-Moog for your feet because it has very similar filters to the prestigious Mini Moog.

Update via TJ: " There might have been a third. The Taurus II models were the 343A synth brain with the same innards as the Rogue, coupled with the 343B pedal unit that gets it's power from a 5 pin DIN cable. The 343B had a threaded sleeve in the center for attaching stand between the pedal and brain.
There was also a stand alone pedal that might be the third model? The 343C used the same AC wall wart as the Rogue and Taurus brain, but had no threaded sleeve in the center and had outputs for pitch CV, V-trig and S-trig, along with a scale and range trimers. The logo on the unit clearly reads "Taurus II Controller" I have seen a Moog ad for these, it was basically a Taurus II pedal without the Rouge brain. As far as not sounding as good as the original Taurus depends! I have mine hooked up to a 1969 Moog Modular System 1P. With three 901 oscillators, the 904a filter and 907 filter bank and sequencer, the bass can shake the floors and rattle the windows! YMMV."
