Electronic Audio Experiments 0xEAE Fuzz

The 0xEAE Fuzz is our latest collaboration with the design collective Obstructures and is the most dangerous gain device in our lineup to date.

The imposing neo-brutalist geometry houses the auditory equivalent of an angle grinder. There is no subtlety or transparency to be found here. This belligerent and deceptively versatile op amp fuzz circuit is capable of over +80dB of gain with a massive volume output. The Weight control adjusts a lightly resonant pre-gain high pass filter at the input, for tones ranging from tight, ripped-speaker grind to bass-rich aluminum sludge. The Texture control blends in a full-wave rectified analog signal, producing an octave up that gets fed into the fuzz input. At higher settings it creates piercing intermodulation products and sub-bass artifacts with a synthesizer-like attack.

Finally, we included our robust bypass switching and voltage-protected power supply infrastructure—making the 0xEAE Fuzz a rugged tool for many years of fuzzed-out rancor.

Please note: each enclosure faceplate is individually finished by hand using an acid etch process. Some variation is normal!

Specifications

Bypass: Relay switching with op amp buffered bypass.

Input impedance @ 1 kHz: 2.2MΩ

Output impedance @ 1 kHz: <1kΩ

Power: 9V DC, 2.1x5.5 mm center negative barrel. The current draw when active is 120 mA. We recommend a regulated, isolated power supply rated for 200 mA minimum. The PSU input is protected against reverse polarity and over-voltage. Our pedals do not accept batteries.

Dimensions: 6.75” x 3.5” x 2”

Weight: 1.5 lbs

Controls

• Master: Output volume level. Slide right to get loud. Very, very loud.

• Texture: Slide right to blend in an analog octave up at the input of the fuzz circuit. Low settings add broken harmonics, high settings add a strong 2nd harmonic with harsh overtones and sub-bass artifacts.

• Gain: Primary gain stage. Slide right to add gain up to an irresponsible +80dB. For conventional sounds, keep below halfway. This control is not for the meek. Expect, embrace, and channel the noise.

• Weight: Changes the cutoff of a high pass filter at the input to alter the attack and thickness of the fuzz. Slide left for a tight attack, slide right for crushing bass frequencies. Highly interactive with the Texture and Gain controls.

• Footswitch: Effect activator.
