Eurorack version of the famed Pit Viper overdrive pedal… with more gain and extra features! Full-blooded distortion Pit Viper is a solid state overdrive for hard-boiled musicians. The circuit can generate clean, beefy signal boosts. However, its true strengths lie in aggressively screaming distortions with a tangible character. This is not a module for wimps! Although the Pit Viper has a raw look, the module was built with much love for detail. The OP amp (TLC2272) can be exchanged for other models. Unused soldering points on the circuit board allow musicians who are dissatisfied with the rather erratic behavior of the viper to replace the hand-rolled optocouplers with precision components. Please note: Such modifications void the warranty! Pit Viper comes equipped with the following control elements: Toxicity: Gain potentiometer Please turn up for heavy distortion. Hiss: Tone knob Turn clockwise to cut the treble. Venom: Volume potentiometer Fear: Three-stage soft clipping switch Activates normal soft clipping or a more tube-like version with less treble. Malice: Three-stage hard clipping switch Activates beefy hard clipping or a spongier version with less treble. Blend: Dry / Wet potentiometer Bite: CV input plus attenuator to cut the high frequency range. Without a cable plugged in, the knob can be used for adjusting the treble manually. Saturation: CV input plus attenuator and on/off switch to influence gain and saturation. Filter: CV input plus attenuator and on/off switch to control the Vipers strange feedback filter circuit. Via a jumper on the circuit board, users can choose between several filter types – some of which self-oscillate in the weirdest way possible: Passive clipped low pass Unbuffered high pass Buffered high pass Buffered low pass Furthermore, there is a trim potentiometer on the circuit board, which can be used to adjust the gain.
