The Fender Hello Kitty Fuzz is an op-amp fuzz pedal from Fender, released as part of a collection celebrating the 50th anniversary of the Japanese cartoon character1. It puts an op-amp fuzz circuit inside a compact, pedalboard-friendly metal enclosure dressed in Hello Kitty styling, and Guitar World's Jonathan Horsley found it can dial in "Cherub Rock-sounding tones", op-amp fuzz in the Siamese Dream vein1.
Fender's own description of the pedal says it "kicks your guitar into woolly, splattering gain tones with unmistakable character"2, and Pedal of the Day's verdict on the Pink version was blunt: "hats off to Fender, this Fuzz sounds AWESOME"3.
An op-amp fuzz in a Hello Kitty case
The circuit is the story here. Guitar World describes "an op-amp doing the heavy lifting" inside the housing1, and RockBoard's listing likewise calls it an opamp-based circuit1. Op-amp fuzzes are a known flavor on pedalboards: the design pushes an operational amplifier into clipping rather than relying on transistors, a lineage players associate with the Smashing Pumpkins' Siamese Dream rhythm guitar sound. Horsley makes that connection directly, writing that "you can definitely dial in some Cherub Rock-sounding tones"1.
The enclosure is a super-rugged metal build, compact and pedalboard-friendly, with a trio of "witches' hat" amp-style knobs carrying the "F" for Fender branding molded on top1. The pedal sits in Fender's wider fuzz range alongside the Fender Pelt Fuzz, the Fender Shields Blender and the Fender Fuzz Wah, but it is the only one wearing a cartoon cat.
The collection context matters for players deciding whether this is a novelty or a tool. Pedal of the Day describes the Fender x Hello Kitty collection as merging "the supercute and colorful aesthetic of Hello Kitty with the road-reliable excellence of Fender gear"3. Guitar World's overall verdict leaned toward the tool side: "Cute design, wild tones, and versatile", with the enclosure "built like a tank"1.
"Cute design, wild tones, and versatile."
The controls
Three knobs sit on top, plus one trimmer inside:
| Control | What it does |
|---|---|
| Fuzz | Sets the gain, covering "a wide range of flavors from overdrive-like grit to full-on ripping fuzz"23 |
| Tone | Shapes the frequency balance of the fuzzed signal12 |
| Volume | Sets the output level12 |
| Internal trim pot | Adjusts treble, inside the enclosure1 |
The Fuzz knob is the one doing the interesting work. Both Fender's description and Pedal of the Day's review say the single control spans everything from overdrive-like grit to full-on ripping fuzz23, which means the pedal can sit in for light breakup duties as well as full fuzz walls. The internal treble trim pot gives a secondary voicing adjustment without adding a fourth knob to the face1.
Power and connections
The rear panel is standard pedalboard fare: a 1/4" input, a 1/4" output, and a power supply input1. For power you have two options:
Guitar World gives two current draw figures: 88mA in its spec box, and 80mA at the power supply input in its review text1. Either way, that draw is modest by modern standards and well within what a typical isolated pedalboard supply delivers per output. Note that the adaptor is not included, so plan on supplying your own.
The bypass is switchable between true bypass, buffered, or both1. If you run long cable runs or a big pedalboard, the buffered option can help preserve your high end when the pedal is off; if you want the pedal to disappear entirely from the chain, true bypass is there too.

Questions
Is the Fender Hello Kitty Fuzz true bypass?
Yes, and more. Guitar World's review lists the bypass as true, buffer, or both, switchable, so you can choose how the pedal behaves when disengaged. Pedal of the Day also describes the Pink version as true bypass switching that keeps your signal clean when the effect is off.
What colors does the Fender Hello Kitty Fuzz come in?
Guitar World lists the pedal as available in White and Pink, with the Pink version as reviewed. The Pink version is the one Pedal of the Day covered in January 2025, and RockBoard's listing also describes a pink-clad pedal.
Where is the Fender Hello Kitty Fuzz made?
According to Guitar World's review, the Fender Hello Kitty Fuzz is made in China.
What kind of fuzz circuit does the Hello Kitty Fuzz use?
It uses an op-amp fuzz circuit. Guitar World's Jonathan Horsley describes an op-amp doing the heavy lifting, and both RockBoard's listing and Pedal of the Day describe it as an opamp-based circuit with three simple controls.
How much does the Hello Kitty Fuzz weigh?
Guitar World lists the weight as 1.1 lbs, or 0.5 kg, which keeps it compact and pedalboard-friendly alongside its small footprint.
