The Fuzz Imp Furia is an HM-2-based metal distortion, described by Guitar Pedal X as a grinding chainsaw distortion that takes the Boss HM-2 format further. Rather than a straight copy, it is an extended range HM-2 derived and inspired chainsaw fuzz, adding a Dry Blend control, a Gate switch and a Mids-Shift Voice switch to the four-control layout of the original HM-2. It was designed by Fuzz Imp's Justus Gash in collaboration with Cue The Sun's Wyatt and Ben.123
Controls
The Furia carries more controls than the HM-2 it is based on. Guitar Pedal X lists them as follows1:
| Control | What it does |
|---|---|
| Loud | Output volume |
| Dry Blend | Blends dry signal with the distorted signal |
| Gain | Amount of distortion |
| Bass | Low EQ |
| High | High EQ |
| Gate | Switch between HM-2 and Tighter gating |
| Voice | Switch between HM-2 and Mids-Shift voicings |
For comparison, Guitar Pedal X notes that the original Boss HM-2 has just four controls: Level, Lows, Highs and Distortion, where Justus further added a Dry Blend.3
Sound and circuit
The Furia is a hard clipping device, which Guitar Pedal X identifies as the source of the distinctive Twin-Peaks Frequency Output Shape associated with the chainsaw sound.1 Of the HM-2 family of sounds generally, the same reviewer has written that the Boss HM-2 "kind of has a rather distinctive fuzz-y side to it - somewhat adjacent to the Shin-ei FY-2 Companion Fuzz".5 Of the Furia itself, he wrote that it has "one of the meanest barks ever if you want to go full-on!"2
Power and running at 18V
The Furia runs on 9V to 18V DC with a negative tip, drawing 50mA, with a TS input and TS output.1
Guitar Pedal X's reviewer found that at 9V the output volume is lower than other HM-2 variants and that the Loud control never goes quite loud enough, but that 18V raises it sufficiently. If headroom and output level matter, the 18V option is worth using.1
Versions and availability
Guitar Pedal X lists a Furia 2 among Fuzz Imp's compact pedals, describing it as an HM-2 derived chainsaw fuzz with Dry Blend, Bass, High, Gate, Voice and CueTheSun controls.2 The Furia is available in one or two alternative colourways, typically including a hammered copper variant.1 As of July 2025, Guitar Pedal X reported the Furia available through the Fuzz Imp webstore at $169.99.3 In its roundup of the year's distortion releases, Guitar Pedal X listed the Furia Searing High Gain Chainsaw Distortion at $169.4

Questions
Is the Fuzz Imp Furia a Boss HM-2 clone?
Not exactly. Guitar Pedal X describes it as an extended range HM-2 derived or inspired chainsaw fuzz. The original Boss HM-2 has four controls: Level, Lows, Highs and Distortion. The Furia adds a Dry Blend, a Gate switch and a Mids-Shift Voice switch on top of the familiar format, taking it beyond a straight copy of the Boss HM-2.
What is the difference between the Furia and the Furia 2?
Guitar Pedal X lists the Furia 2 as an HM-2 derived chainsaw fuzz with Dry Blend, Bass, High, Gate, Voice and CueTheSun controls. The original Furia is described as an HM-2-based metal distortion with a Dry Blend control, a Gate switch and a Mids-Shift switch, so the two share the same basic format with the Furia 2 as a later version.
Does the Furia run on a battery?
The published specifications give the Furia a 9V DC negative-tip power input drawing 50mA, with a 9V to 18V DC range. No battery operation is mentioned in the available coverage, so plan on a standard center-negative DC supply, and note that running at 18V raises the output volume according to Guitar Pedal X's review.
What does the Voice switch do on the Furia?
The Voice switch selects between two voicings, HM-2 and Mids-Shift. The HM-2 setting follows the classic Boss HM-2 chainsaw character, while Mids-Shift alters the midrange emphasis. It sits alongside a separate Gate switch that toggles between HM-2 and Tighter gating, giving the pedal more tonal and noise-control options than the original HM-2 format.
Does the Furia sound louder at 18V than at 9V?
Guitar Pedal X's reviewer found that at 9V the output volume is lower than other HM-2 variants and that the Loud control never goes quite loud enough, but that running the pedal at 18V raises the output volume sufficiently. If maximum volume matters to you, that reviewer's experience suggests running it at the higher voltage.
Who designed the Fuzz Imp Furia?
Guitar Pedal X reports that Fuzz Imp's Justus Gash collaborated with Cue The Sun's Wyatt and Ben on the Furia. The pedal is described as a grinding high-gain chainsaw distortion with additional smart controls beyond the original HM-2 format.
