The Jed's Peds Fat Maggie Fake-tory Fuzz is a DIY guitar effects pedal kit for a germanium based fuzz. The maker states that the circuit compares to the Fat Fuzz Factory by Zvex, and describes five very interactive knobs producing odd tones, weird noises, gated fuzz and drive, along with a three-position FAT toggle.1
What it is and how it sounds
Jed's Peds describes the Fat Maggie as a germanium based fuzz, a circuit family known in general for a softer, vintage-flavored clipping character compared with silicon designs. The maker's own description leans into the circuit's unrulier side: "Five very interactive knobs on this one, with some very odd tones to boot," covering gated fuzz and drive as well as "weird noises."1 The three-position FAT toggle, the maker says, adds "even more versatility to an already fantastic circuit."1
Because the knobs are described as very interactive, the tones available range well beyond a standard fuzz, and players comfortable with the Fat Fuzz Factory's approach will find the same idea here: settings that gate the fuzz into choppy, spluttering textures alongside more conventional sustained fuzz tones.1
Kit versions and what you get
The Fat Maggie is sold in five versions, from a bare board to a fully drilled kit:1
| Version | What it includes |
|---|---|
| PCB Only | Just the plain PCB |
| PCB & Components | PCB with components |
| PCB & Components and off board parts | Adds the off board parts |
| Full Kit | Complete kit, including the JP125B enclosure |
| Full Kit & Drilling | Full Kit with all holes drilled, for a small surcharge |
The kit is supplied with a JP125B enclosure, and the PCB hangs from the pots and toggle, which is how the board mounts inside the box.1
The Pre Built Kit does not come with knobs fitted. Jed's Peds warns: "you must add your knobs from the knob section or it will come without any!"1
Pre-built option, price and warranty
For players who would rather not solder the build themselves, Jed's Peds offers a Pre Built Kit priced at £51.00 GBP as of 26 October 2026.1 The maker's terms on this option are specific: "There are no returns accepted on these but I do give a 12 month repair warranty."1
Drilling is an optional extra for the Full Kit, with a small surcharge, and covers all the holes needed for a complete pedal, so the enclosure arrives ready for the pots, toggle and jacks.1
