Walrus Audio Silt Harmonic Fuzz 

Unearth a colossal new dimension of fuzz tone with the Walrus Audio Silt Harmonic Fuzz, an analog circuit masterpiece designed in collaboration with tube guru Jim Hagerman. This isn't just another dirt box; the Silt is built around the heart of a genuine 12AU7 pre-amp tube as its primary drive section. This core design choice provides a foundational warmth and bone-rattling grit that only a true tube circuit can deliver, wrapping your tone in a thick, amber glow while retaining the complex, musical textures that make fuzz so addictive.

The Silt is a versatile 2-in-1 monster, capable of producing massive, rich fuzz tones perfect for power chords and chunky rhythm parts. Engage the unique Harmonic Mode switch, and you inject a frequency doubler-like effect before the tube drive section, unleashing crispy, octave-like overtones that lend a wild, unmistakable edge to your leads and solos. Further tone sculpting is provided by the Contour control, a 3-way pre-tube EQ stage that toggles between high-pass, flat, and low-pass curves, allowing you to fine-tune your fuzz to your pickups and amplifier with precision.

Housed in a sturdy die-cast enclosure with striking artwork, the Walrus Audio Silt is a perfect blend of modern engineering and classic tube tone. Its ability to operate between 9V and 12V DC allows for an extra gain boost at the higher voltage, pushing the pedal's primal boundaries to deliver searing, harmonically complex tones. Whether you're chasing woolly rhythm or cutting, searing leads, the Silt will adapt and deliver with roaring precision.
