The CRUSTIFIXION v2 is an advanced analog distortion pedal from This Heavy Earth, built on the classic Boss HM-2 Heavy Metal circuit. The HM-2 circuit is the origin of the so-called "chainsaw" sound favored in extreme metal, and RockBoard's PedalPedia describes the v2 as designed for exactly those tones1. It sits in the maker's range alongside other heavy-oriented pedals such as the Flesh Rot V2, the CHVRCHBVRNER, the Slaughter, the Widower High-Gain Distortion and the Bad Trip.
What it does
The v2's main addition over the HM-2 blueprint is a four-band gyrator EQ, including a dedicated low-mid control for precise frequency sculpting1. A gyrator EQ uses active circuitry to simulate inductors, which is how the original HM-2 achieved its aggressive, voiced tone controls. The dedicated low-mid band gives players a handle on the frequency range the stock HM-2 famously scooped or boosted, depending on where the knobs were set.
For players comparing options in the wider category, the pedal belongs to the distortion family, and its HM-2 lineage places it among pedals aimed at death metal, crust and other high-gain styles where that midrange character matters.
The pedal runs on 9V DC, center negative, so it works with a standard pedalboard power supply1.
