Cusack Music Orthrus Distortion
Cusack Music · pedal
The Cusack Music Orthrus is a US-built high-gain distortion pedal based directly on a true amplifier preamp circuit, with an unconventional three-band EQ where Treble reaches into very high frequencies, Mid works more like a pick-attack and sizzle control centered on the upper midrange, and Bass behaves closer to a cabinet-resonance control than a simple low-end knob. Gain and volume run deep, giving serious headroom for everything from crunchy rhythm to saturated lead distortion, with the reworked EQ voicing doing most of the tonal heavy lifting rather than the gain stage alone. A momentary or latching boost, switchable between 3, 6, and 9dB, adds a warm, saturated push for solos, and a stutter/kill switch chops the signal for rhythmic effects. It suits players chasing trash and metal tones who want an amp-derived EQ with real character rather than a standard three-band voicing.
