Description

Introducing the Walrus Audio Silt Harmonic Fuzz, an innovative fuzz pedal that forms the perfect blend of traditional and modern soundscapes. This collaborative creation, crafted with tube expert Jim Hagerman, is a unique harmonic fuzz pedal boasting an internal 12AU7 tube and two distinctive modes.

This pedal offers a rich, warm fuzz sound that's perfect for chords and rhythmic playing styles. It's equipped with a Harmonic Mode that adds distinctive, octave-like overtones to your signal before it enters the tube, creating a unique and wild sonic landscape. The fuzz pedal operates from 9V to 12V, offering additional gain at 12V for even more fuzz.

The Silt Harmonic Fuzz also features a Contour Switch that helps adapt to different pickups and provides even more tonal variability. This contour circuit comes before tube distortion and offers three options: Hi-Pass, Flat, Lo-Pass. With this, you can easily refine your fuzz tones and achieve a wide spectrum of timbres.

Its true bypass circuit helps maintain the integrity of your original tone, preserving your guitar's natural voice even when the pedal is not in use.

Critic Reviews

Walrus Audio Silt Harmonic Fuzz review | Guitar World

guitarworld.com

The Walrus Audio Silt Harmonic Fuzz is a standout in a crowded fuzz market, delivering rich harmonic textures thanks to its unique tube design. Its compact size, flexible EQ options, and footswitchable Harmonic mode allow for a wide range of sounds, making it a versatile addition to any pedalboard. However, the transition to Harmonic mode while the effect is engaged can feel a bit clunky, detracting from an otherwise seamless experience. Overall, it’s a compelling choice for guitarists seeking depth and character in their tone.
