The Malekko E.Filter Omicron Analog Filter puts high functionality and compact size in perfect alignment with a super small chassis, two-knob control interface of range and frequency, and the crown jewel VTL5C2/4 vactrol for unprecedented response. Ranged in character, the E.Filter goes from a subtle edge to a full-on funk attack through a few easy twists of a knob. Ideal for guitar, this pedal's versatility makes it an option as well on baritone guitar and guitar.
