The Monochrome Fuzz One is an analog fuzz pedal built in Italy, designed to sit between drive and collapse: enough gain to raw up a tone, without losing the note underneath. Pedal of the Day, reviewing it in November 2025, found that "it stays raw yet articulate, open and touch-sensitive, reacting to every nuance of your playing"1.
A fuzz that stays articulate
Fuzz pedals are often accused of flattening everything they touch. Pedal of the Day's reviewer made the opposite case here, writing that "fuzz pedals can be temperamental, finicky and down right frustrating at times, that is most definitely NOT the case" with the Fuzz One1. The pedal responds to your guitar's volume and dynamics, cutting through an effects chain with definition and texture, which means rolling the guitar volume back cleans it up rather than just making it quieter1.

The pedal's controls are simple. The Weight control shapes the low end, taking the bottom from lean to heavy depending on how much low-end push the part needs1.
A closely related pedal is the Tape Audio Co. ONE Fuzz, which Paolo De Gregorio of Delicious Audio described in similar terms: "love how it adds texture and color while maintaining simplicity"2.
Germanium and silicon voicings
Two clipping modes define the Fuzz One's voice, and the difference between them is the usual germanium-versus-silicon contrast1:
The germanium side uses the softer, compressed character players associate with older fuzz designs, while the silicon side leans toward clarity and attack1. The related Tape Audio Co. ONE Fuzz uses NOS germanium diodes in its clipping stage2.
The Fuzz One is available in several different variants1, so the exact clipping parts and artwork can differ between versions.
Power and placement
The Fuzz One runs on 9V DC. Pedal of the Day recommends an isolated 9V DC supply for best performance, and also suggests placing it early in the signal chain1. The maker's page for the related ONE Fuzz likewise specifies that a high quality 9V, regulated and filtered DC power supply is required2.

Questions
Is the Monochrome Fuzz One germanium or silicon?
Both. It has two clipping modes that define its voice: germanium for warmth and smooth compression, and silicon for clarity and attack. Pedal of the Day noted that, unlike many fuzz pedals that lock you into one temperament, this one offers something for everyone whether germanium or silicon, and found it not temperamental or finicky.
Where is the Monochrome Fuzz One made?
Italy. Pedal of the Day reports that the pedal comes from the Ligurian Alps in Italy, and it is available in several different variants.
What power supply does the Monochrome Fuzz One use?
A 9V DC supply. Pedal of the Day recommends an isolated 9V DC supply for best performance, and the maker's product page specifies a high quality 9V, regulated and filtered DC power supply is required.
Is the Monochrome Fuzz One analog?
Yes. Pedal of the Day describes the Fuzz One as an analogue fuzz, designed to live between drive and collapse.
Does the Monochrome Fuzz One clean up with the guitar's volume knob?
Yes. According to Pedal of the Day, the Fuzz One responds to your guitar's volume and dynamics, cutting through effects chains with definition and texture, so rolling back the guitar volume shapes how much fuzz you get.
