STG Sound Labs -largely known for their Moog modular format modules, is fronted by Mr Suit Et Tie Guy - I honestly dont know his real name! We're looking at the .MIX module, a simple 3 channel Audio and or CV mixer module based around the transistor based circuit design of the Moog CP3.

But it's not actually that straightforward, using a bi-polar output pot, the signal can be twisted through 180 degrees, creating a negative or positive result. This is particularly useful when inverting Sawtooth waves or other signals, both for audio processing and CV modulation sources. A nice touch.

As the circuits only use transistors, rather than Op-Amps, as in the are Moog CP3 mixer module,  it can also be driven to distortion quite easily, adding extra harmonics.

Available now $130/ €113.

tbh... i think you did suit a bit of diservice with what you showed. i have one of these and the real beauty to this module is in the blending and soft sat of the wave forms, it kinda smashes two waves into one , like the old moog mixer CP3, ry a week nsawtooth and take a bit of sine from same osc then wigle tem till they just satrt to clip and oresto you now have a fat sawtooth love the show btw. sorry but it had to be said P.S.when you gonna do an interview (online of course ) with tony rolando and buddies

Further to wooster77's comment; it's not just distortion or overdriving an Opamp, it's driving the voltages to the edge of their rails to the standpoint that they warp and eventually flatten; This could be described as 'clipping' to some extent but I'd avoid that term as it now has a stigma behind it thanks to digital clipping which this is not.

But back on topic, take a sawtooth waveform and drive it hard and you can both see the effect and hear it; If I'm not mistaken, these are calibrated such that 2 o'clock is unity gain on any particular channel (at least that's how the MU version is calibrated).

If you read the description (or look on the board), you'll see a -6V voltage regulator; that's right, the meat of this modules IS a clone of the Moog circuit which originally ran at +12 and -6V.

Tired of reading? (too late) but watch this excellent video of JLR demonstrating the MU version of this module:
