The Hilbish Design T-Fuzz is a two-knob, two-mode octave fuzz pedal from Hilbish Design's lineup. Its single mode switch selects between two fuzz voices, red and green, and the maker says the pedal covers ground from classic fuzz tones to what it calls "noisy sputtery fuzz insanity"1. Delicious Audio described it as "a simple, two-knob and two-mode octave fuzz pedal"2, which is a fair summary of the whole design: two knobs, one switch, and a lot of gain on tap.
The pedal carries artwork by Mackie Osborne1, and Hilbish Design lists it at $230.00 USD1.
Two fuzz modes, red and green
The T-Fuzz's main feature is its pair of fuzz voices, selected by the mode switch1. The two modes are aimed at different jobs:
| Mode | What the maker says it does | What reviewers found |
|---|---|---|
| Red | "Produces a refined heavy fuzz tone"1 | Premier Guitar's reviewer found it "lends force and focus to power chords"3 |
| Green | "Yields an ear splitting fuzz tone perfect for noisy leads"1 | Delicious Audio characterized the pedal's range as running "from classic (red mode) to sputtery (green mode)"2 |
In practice, the red mode is the tamer of the two, and the green mode is where the pedal gets loud and unstable in the way octave fuzzes can. Premier Guitar's reviewer summed up the overall character by writing123:
"The T-Fuzz is not trashy to the point of absurd."3
That verdict is worth noting for players comparing this against more extreme octave and pitch fuzzes: the T-Fuzz pushes hard, but the reviewer found it stays usable32.
The controls
The control set is minimal, with two knobs and a switch2:
| Control | What it does |
|---|---|
| Fuzz | Controls the intensity of fuzz1 |
| Volume | Controls overall signal level1 |
| Mode | Switches between the two fuzz modes1 |
Delicious Audio's write-up lists the same three controls with the same functions2, so the maker's description is consistent across sources. There is no tone control, so the shape of the sound is set by the mode you choose and how hard you push the Fuzz knob.
Premier Guitar also noted that the red mode is activated via a low-profile push button3, a detail worth knowing before you buy, since it affects how you switch modes mid-song compared with a standard toggle.
Power and setup
The T-Fuzz runs on a 9V supply with a 100mA draw and a center negative jack1, the same arrangement as most modern pedals. Delicious Audio lists the same power spec2. Any standard 9V pedalboard power supply with center negative outputs will drive it.
The maker's spec is 9V at 100mA center negative1. Supplies that only offer lower current per output, or positive center barrels, will not work without an adapter.
Where it came from
Hilbish Design lists the T-Fuzz at $230.001. The pedal sits in the maker's lineup alongside its other octave fuzz collaborations, including the Deathimizer and the Deathimizer King Buzzo Octave Fuzz.
The T-Fuzz runs on a 9V center negative supply drawing 100mA1, a draw high enough that it expects a proper power supply rather than a battery.

Questions
How much does the Hilbish Design T-Fuzz cost?
Hilbish Design lists the T-Fuzz at $230.00 USD on its product page. That is the maker's list price as of October 2026, so street prices at retailers may differ.
What power supply does the T-Fuzz need?
The T-Fuzz runs on a 9V power supply with a 100mA current draw. It uses the standard center negative arrangement common to most guitar effect pedals, so a typical pedalboard power supply will work.
What is the polarity of the T-Fuzz power jack?
The power jack is center negative. That is the same polarity as most modern effect pedals, so it works with standard 9V pedalboard supplies and daisy chains.
What is the difference between the red and green modes?
The red mode produces a refined heavy fuzz tone, which Premier Guitar's reviewer found lends force and focus to power chords. The green mode yields an ear-splitting fuzz tone that Hilbish Design describes as perfect for noisy leads, with a sputterier character than the red mode.
Who did the artwork on the T-Fuzz?
The artwork on the T-Fuzz is by Mackie Osborne, credited by Hilbish Design on the pedal's product page. Osborne is known for her cover art for the Melvins.
When was the T-Fuzz expected to ship?
When the pedal was announced, Hilbish Design said the T-Fuzz was expected to ship at the end of September 2019. The product page listed the pedal as coming soon at that time.
