The Fjord Fuzz Thor is a fuzz pedal from Norwegian builder Fjord Fuzz, announced in September 2025. It is a silicon fuzz built on a 3-transistor Tone Bender MKII core, but it is not a straight vintage clone: Guitar Pedal X calls it "a wild, versatile gated, Velcro, octave, oscillating and silicon fuzz"1. Delicious Audio describes it as "a storm of glitchy, gated, and bass-heavy textures designed to shatter musical predictability"2.
The pedal was conceived years ago but, as Delicious Audio puts it, was "deemed too untamed for its time" before finally being released2. The maker says THOR was his third ever circuit, following EMBLA and ODIN3.
What it does to your sound
Thor covers a wide spread of fuzz territory from one small box. Guitar Pedal X's reviewer lists its modes as "Drone, Gated, Sputtery, Foghorn, Percolating Engine, Classic, Harmonic Octave, Searing, and Oscillating tones" among many other textures1. In the same outlet's round-up of 2025's best new fuzz pedals, he called it "a truly wild and unruly fuzz in the best possible way," one you can make "squeal, sear or percolate"4.
Two concrete settings from that review give a sense of the range:
| Setting | Result |
|---|---|
| Stark full, Sturm back, Drang full | Searing fuzz1 |
| Sturm around 9 o'clock, Drang around 8 o'clock | Broken diesel engine tones1 |
Delicious Audio cautions that dialing it in takes a deft touch: "minute adjustments can dramatically shift the texture, rewarding patience with uniquely elemental tones"2. Guitar Pedal X adds that the builder, Daniel, intends the pedal as "an experimental journey," leaving players to investigate the outer reaches of its abilities themselves1.
The controls: Stark, Sturm and Drang
Thor has three knobs, all named by Daniel from the German phrase Sturm und Drang, with the volume control called Stark1. Delicious Audio describes the set as "a highly interactive 3-knob design... that functions less like traditional controls and more like a complex, interlocked system"2.
| Control | What it does |
|---|---|
| Stark | Volume; affects the overall sound as it is cranked up1 |
| Sturm | Q1 bias4 |
| Drang | Q2 bias4 |
The two bias controls are where the character lives. According to Guitar Pedal X, Sturm and Drang "combine bias, filter and gain, producing natural gating and tones ranging from drone, sputtery and percolating to classic, harmonic octave, searing and oscillating"1. The maker's own description is broader still: the two lower knobs "set your oscillations, tone, feedback, heterodyning, madness and emotional weight"3. All three controls are highly interactive, so a setting that works on one knob changes when you move another1.
"Stark is the Volume control; all three are highly interactive."
The circuit: silicon Tone Bender MKII lineage
Thor is a silicon fuzz, which Guitar Pedal X characterizes as "a kind of 3-Transistor (Silicon) Tone Bender MKII"1. The maker notes it was his third circuit, after EMBLA and ODIN3. A later Guitar Pedal X review adds that the circuit is "in part derived from the Blackout Effectors Fuzz Bear, but with just 3 controls for maximum chaos"4.
A related pedal, the Fjord Fuzz Thor Wild, carries the same control set and the same $199 price, and appears in Guitar Pedal X's 2025 fuzz round-up alongside the standard Thor4.
Price, colors and availability
The Fjord Fuzz Webstore lists the Thor at $199.00 USD, with shipping usually in about 2 to 6 weeks3. At launch, Guitar Pedal X reported the same $199 price via the Fjord Fuzz Webstore, and £229 through Andertons in the UK1. Delicious Audio also listed it at $1992.
On colors, the launch coverage reported Space Gray and Hendrix Red editions1, and the maker's product page images show pink, standard and sulphur variants as well3.
Prices differ by region: the Fjord Fuzz Webstore lists $199.00 USD3, while UK availability was reported at £229 through Andertons at launch1.
What reviewers said
Guitar Pedal X's Stefan Karlsson reviewed the Thor at launch and placed it among the builder's best work14:
"This is instantly one of my favourite fuzzes - right up there with Fjord Fuzz’s own Gjallarhorn - where it overlaps a little with some of its tones - but it has a lot more variety and versatility onboard"
In the outlet's year-end round-up of new fuzz pedals, he summed it up as a wild and unruly fuzz with many weird and wonderful sounds on board4. Delicious Audio's take frames it as a pedal for experimentalists rather than players who want a predictable, set-and-forget fuzz2.

Questions
What do Stark, Sturm and Drang do on the Fjord Fuzz Thor?
Stark is the volume control, and it affects the overall sound as it is cranked up. Sturm and Drang set the bias of the first and second transistors, combining bias, filter and gain to produce natural gating and everything from drone and sputter to octave and oscillation. All three controls are highly interactive, so small changes on one knob shift what the others do.
Is the Fjord Fuzz Thor a silicon or germanium fuzz?
It is a silicon fuzz. Guitar Pedal X describes it as a kind of 3-transistor silicon Tone Bender MKII, so it uses silicon transistors rather than the germanium parts found in some vintage fuzz circuits.
How much does the Fjord Fuzz Thor cost?
The Fjord Fuzz Webstore lists the Thor at $199.00 USD, and it usually ships in about 2 to 6 weeks. In the UK, Guitar Pedal X reported a price of £229 through Andertons at the time of its 2025 launch coverage.
What circuit is the Fjord Fuzz Thor based on?
It is built on a 3-transistor Tone Bender MKII core. The maker says it was the third circuit he ever designed, following the EMBLA and ODIN pedals, and a later review notes it is in part derived from the Blackout Effectors Fuzz Bear.
What colors does the Fjord Fuzz Thor come in?
At launch, Guitar Pedal X reported Space Grey and Hendrix Red editions. The maker's product page images also show pink, standard and sulphur color variants.
Can the Fjord Fuzz Thor make octave and oscillating sounds?
Yes. Guitar Pedal X lists Drone, Gated, Sputtery, Foghorn, Percolating Engine, Classic, Harmonic Octave, Searing and Oscillating tones among its range of textures, and the maker describes the two bias controls as setting oscillations, tone, feedback and heterodyning.
