Based on a Big Muff, but a lot of added features and a bit heavier sound. Added clean blend, mids knob, buffer switch and a Russian mode switch which gives you a Green Russian sounding fuzz. Also has a "Hail Satan" footswitch which switches to 5mm LED diodes in the distortion clipping. The goat's eyes light up red with the LEDs while playing.
Great sounding and looking fuzz with a lot of versatility and at a low cost. Only reason why it gets 4 out of 5 stars is that it can sound a bit too chunky on guitar when dialing down the tone.
