EarthQuaker Devices Barrows
A portal to the legendary TB MkII fuzz circuit

Greetings, tone archaeologists and fuzz disciples! The Barrows is a tribute to one of the most revered and mystical circuits in the pantheon of guitar effects—the classic three-transistor TB MkII. This germanium-driven masterpiece brings the crushing riffs and walls of sound that defined generations of rock, while adding modern refinements that make it a powerful tool for today’s players.

From dawn-of-metal dirges to shoegaze symphonies, the MkII has been the foundation of countless sonic monuments. With Barrows, you can channel that same lightning-in-a-bottle magic while enjoying the reliability and versatility of modern craftsmanship.

Key Features

• Matched Germanium Transistors: Carefully selected for authentic, harmonically rich sustain and fuzz character.

• Classic Meets Modern: Delivers signature mid-focused tones with low-end authority and top-end grind, plus added stability and versatility.

• Phase-Corrected Output: Buffered for compatibility with other pedals and higher output volume.

• Compact Pedalboard Footprint: Big fuzz tones in a space-saving design.

• Modern Power: Standard 9V DC negative center operation—no more positive-ground quirks.

• True Bypass Switching: Pristine signal when disengaged.

Controls

• Level: Sets output volume. Unity gain around noon, with extra boost to push amps into overdrive.

• Attack: From amp-like distortion at low settings to massive, sustain-heavy fuzz at max.

Pro Tips

• Place Barrows first in your signal chain for best results—its low input impedance works best when fed directly by your guitar.
