Synthrotek DIRT Filter Now Available

synthrotek-dirtSynthrotek has announced that it has released the DIRT filter – a module that allows for distortion, mangling, wave shaping and other caustic and filter like effects.

DIRT is our new 4HP low-pass filter / effect for the Eurorack modular synth platform.

Inspired by one of our favorite ‘noisy’ filters, the DIRT is an unapologetic filter / effect that produces interesting and unique effects via the Bias knob, accessible from the front panel.
