Note:  This is the kit version of the 9V DIRT Filter. 
DIRT is Synthrotek’s new low-pass filter / effect. Inspired by one of their favorite ‘noisy’ filters, the DIRT is an unapologetic filter / effect that produces interesting and unique effects via the Bias knob.  It’s not a traditional filter; it’s an effects module with filtering, ring mod effects, wave shaping and even outright brutal harmonic distortion. DIRT likes to square things up a bit, so throw in a triangle, sawtooth, sine or other wave forms for different style effects.  Even plugging a guitar (using an external amplification module) into the DIRT produces some great sounds and heavy distortion.
