Project overview

Inspired by Fender Blender. One of the best-sounding old-school style fuzz out there. Don’t miss this germanium-based fuzz box that produces pretty vintage sounds that are utterly feral at the same time.

Introduction

When Fender released their Fender Blender in 1968, it seemed like they were entering late in the game. The war of fuzz pedals had already begun in ’62, and after all, what could they bring to the table? The fuzz fiver that started with the Maestro FZ-1 Fuzz-Tone by Gibson rose through the ’60s and brought numerous incarnations of Fuzz Face, Tonebenders, Shin-ei / Univox Superfuzzes, Mosrite Fuzzrite, and a big etcetera.

It seemed that it was pretty late to release a game-changing fuzz pedal…but history has many plot twists. If Fender was a latecomer to the scene, it had to offer a really good fuzz. And it did it with its impressive octave blend that delivered a total new tonal option!

The rest is well known; bands like My Bloody Valentine and The Smashing Pumpkins popularized the board and his unique sound.

We recreated this historical pedal with all modernizations up to date. The topology is pretty darn close to the Superfuzz, including Germanium diodes, Transistor splitter, and switchable tone control. It sounds awesomely bass-heavy, and we really dig its low end. If you’re not a fan of this, switch the tone control on and get new tonal options.

Become part of history and try this old-school, hard-to-find fuzz that will never go out of style.
