Good 9V DIRT Filter DIY Kit sku-123946691 738676125764

This Good listing is for the kit version of Synthrotek's 9V DIRT Filter, a low-pass filter and effects unit in the General Electronic Accessories category. Inspired by a noisy filter, its Bias knob changes the texture and behavior of the processed signal. It can produce filtering, ring-mod-style tones, wave shaping and harmonic distortion, and tends to square up incoming signals.

Triangle, sawtooth, sine and other waveforms produce different results. It also accepts a guitar through an external amplification module for heavily distorted sounds. SKU: sku-123946691. UPC: 738676125764.
