The PedalFarm F-2 Professional Fuzz is a fuzz pedal based on the MKII Tonebender circuit, re-imagined with silicon transistors and a bias control for a wide range of fuzzy textures1. It sits in the fuzz family alongside PedalFarm's F-1 Classic Fuzz, and it keeps the classic Level and Attack control layout of the original design while adding a precision Bias knob1.
The controls
The F-2 carries three knobs, and each one has been reworked from the classic Tonebender layout rather than copied outright1.
| Control | What it does |
|---|---|
| Level | Extended to ensure full volume capability at lower bias settings, where the signal is weaker, and to allow boosting the amp1 |
| Attack | Modified to provide a better balance to the fuzz range and improved frequency content across the sweep of the knob1 |
| Bias | Provides a wide range of textures and interacts with the Attack control for a multitude of sounds1 |
The Bias control is the addition that sets the F-2 apart from the stock MKII layout. Because bias shapes how a fuzz's transistors clip, sweeping it moves the pedal through different textures, and it combines with the Attack knob for a broad spread of sounds1.
Each F-2 is individually tuned to make it easy to consistently access specific bias points, so the Bias knob's sweep lands on repeatable settings from unit to unit1.
What reviewers said
Pedal of the Day reviewed the F-2 and came away impressed by its overall character1.
"The F-2 Professional Fuzz absolutely RIPS"
That reviewer's verdict is the published take on the pedal's sound; the maker's own framing is a wide range of fuzzy textures from a silicon, bias-controlled take on the MKII Tonebender1.

Questions
Is the PedalFarm F-2 a germanium or silicon fuzz?
The F-2 Professional Fuzz uses silicon transistors. Pedal of the Day describes it as a MKII Tonebender circuit re-imagined with silicon transistors and a bias control, for a wide range of fuzzy textures. Silicon designs are generally less sensitive to temperature than germanium, and here the Bias knob gives the player direct control over the character of the fuzz.
What does the Bias knob do on the F-2?
The Bias control provides a wide range of textures to the fuzz and interacts with the Attack control for a multitude of sounds. Because each F-2 is individually tuned, PedalFarm says it is easy to consistently access specific bias points, so settings repeat from one session to the next.
Which classic fuzz is the F-2 based on?
The F-2 is based on the MKII Tonebender circuit, according to Pedal of the Day. PedalFarm keeps the classic Level and Attack controls of that design but modifies both and adds a precision Bias control.
Why is each F-2 individually tuned?
Each F-2 is individually tuned to make it easy to consistently access specific bias points. That means the Bias knob's sweep lands on usable, repeatable textures rather than varying from unit to unit, which matters on a bias-sensitive fuzz design.
