The Anode Effects MOS Fuzz Full Frequency Fuzz Machine is a fuzz pedal built around an expanded version of the Bazz Fuss circuit, a simple one-transistor fuzz design that has long been a favorite starting point for DIY builders and small pedal makers. Where a traditional Bazz Fuss can be harsh and gritty, the MOS Fuzz uses MOSFETs instead, which Pedal of the Day says creates "a more smooth and less gritty fuzz"1. It sits in the broader family of fuzz pedals as a compact, two-knob take on the design.
Sound and how it cleans up
Pedal of the Day's review describes a fuzz with more low end than the usual design: "It has a lot more bass than a traditional fuzz and has insane cleanup with your guitar's volume knob"1. That volume-knob response is the practical appeal of the circuit: rolling the guitar's volume back takes the pedal from full fuzz down toward cleaner tones without touching the pedal itself.
The review also notes how the pedal behaves at lower gain settings: "Depending on the output of your pickups, the fuzz will turn into a more velcro like fuzz as the knob is turned down"1. Velcro here refers to the choppy, gated fuzz texture some players seek out, so pickup choice and the fuzz knob setting together shape how much of that character you get.
Controls and build
The MOS Fuzz keeps its control layout to two knobs. Pedal of the Day, in a later review of the Anode Effects Dragon Drive V2, looked back at the MOS Fuzz as "a revelation in what could be accomplished with a 2-knob pedal"2.
The build details the review lists:
- All NOS (new old stock) components on the PCB, including carbon comp resistors and Philips and Sprague capacitors1
- Gorva soft click footswitch1
- Lumberg DC jack and Lumberg audio jacks1
- A comic book-inspired enclosure1
What reviewers said
Pedal of the Day's verdict covered both construction and tone: "A solid build indeed, it also sounds fantastic, and will find a place in any pedal setup that needs a little oomph added to it."1

Questions
Is the Anode Effects MOS Fuzz based on the Bazz Fuss?
Yes. Pedal of the Day describes the MOS Fuzz as a unique circuit that is an expansion of the Bazz Fuss circuit, with MOSFETs used in place of the usual transistor arrangement to create a smoother and less gritty fuzz than the original design.
How many knobs does the Anode Effects MOS Fuzz have?
It is a two-knob pedal. Pedal of the Day, reviewing another Anode Effects pedal, pointed to the MOS Fuzz as a revelation in what could be accomplished with a two-knob pedal, so the simple control layout is part of the design rather than a shortcut.
Does the MOS Fuzz clean up with the guitar's volume knob?
According to Pedal of the Day, it has insane cleanup with your guitar's volume knob, and it carries a lot more bass than a traditional fuzz. With the fuzz knob turned down, the pedal can turn into a more velcro-like fuzz depending on the output of your pickups.
What parts are inside the Anode Effects MOS Fuzz?
Pedal of the Day reports that all NOS (new old stock) components were used on the PCB, including carbon comp resistors and Philips and Sprague capacitors. The pedal also uses a Gorva soft click footswitch and Lumberg DC and audio jacks.
