The This Heavy Earth Flesh Rot V2 is a high gain distortion pedal built for death metal tones. Guitar Pedal X's Stefan Karlsson described it as "a really tasty Death Metal Distortion with a hint of the Diezel Herbert also onboard", referring to the amp whose voicing reviewers heard in the pedal1. The same reviewer called it "a high gain Metal Distortion with a hint of Diezel Herbert flavour" in his full review of the pedal2.
Controls
The pedal carries eight knobs, which Karlsson described as "the perfect complement of controls" in his review's title. Shift is the one that sets the Mids Frequency, so the midrange control works against a frequency you can move rather than a fixed one2.
| Control | What it does |
|---|---|
| Gain | Amount of distortion |
| High | Treble EQ |
| Mid± | Midrange cut and boost |
| Low | Bass EQ |
| Shift | Sets the Mids Frequency2 |
| Presence | Top end lift |
| Tight | Low end tightening |
| Level | Output volume |
Price and availability
Guitar Pedal X listed the Flesh Rot V2 at $199 in its December 2025 rundown of the year's best new distortion pedals1. The pedal is available direct from the maker, and is also stocked by Effekt Boutique in Germany, where Andy Ebsen works; there it goes for €2692.
The two listed prices differ because they come from different sellers: $199 direct, and €269 from Effekt Boutique in Germany12.
What reviewers said
Karlsson's June 2025 review was strongly positive, and he returned to the pedal in his year-end distortion roundup. On the sound and the dialling-in12:
"While this one really sounds fantastic - and is very easy to dial in"
On the Diezel Herbert connection, Karlsson noted that he had read it elsewhere first: "In one of the reviews I read that the Flesh Rot V2 had more than a hint of flavour from the Diezel Herbert"2. The pedal also made Guitar Pedal X's 2025 Full Metal Racket selection of compact high gain and heavy metal pedals, alongside units like the Fortin Kali and the REVV G33.

Questions
What does the Shift knob do on the Flesh Rot V2?
Shift sets the Mids Frequency, the centre frequency that the midrange control works on. Guitar Pedal X lists the pedal's controls as High, Mid±, Low, Level, Shift (Mids Frequency), Gain, Presence and Tight, so Shift lets you move where the mids sit rather than only how much of them you get.
What does the Tight control do on the Flesh Rot V2?
Tight is one of the pedal's eight controls, listed by Guitar Pedal X alongside High, Mid±, Low, Level, Shift, Gain and Presence. On a high gain metal distortion of this kind, a Tight control shapes the low end response, and Guitar Pedal X described the pedal's set of controls as a perfect complement for dialling in heavy tones.
How much does the This Heavy Earth Flesh Rot V2 cost?
Guitar Pedal X listed the Flesh Rot V2 at $199 in its 2025 rundown of new distortion pedals. The same reviewer noted that in Germany, Effekt Boutique stocks the pedal for €269.
What kind of music is the Flesh Rot V2 made for?
It is a death metal style distortion. Guitar Pedal X described it as a high gain metal distortion with a hint of Diezel Herbert flavour, and called it a Death Metal style Distortion in its June 2025 review.
