Walrus Audio SILT Harmonic Tube Fuzz Effect Pedal, Black Walrus Audio

The Walrus Audio SILT Harmonic Tube Fuzz is a collaboration with tube expert Jim Hagerman. This two-in-one fuzz pedal features an internal pre-amp tube that offers a rich tone, and is built for players who seek a harmonic fuzz experience. Also available in this epic red colorway!

The sonic heart of the SILT lies in its 12AU7 tube drive section, offering a warm, saturated fuzz. This analog circuit provides the grit, growl, and harmonically complex textures that only a tube-driven fuzz can deliver, with “Harmonic Mode” acting as a frequency doubler, producing clear octave-like sounds that add a flair to lead tones.

Precision tone sculpting with the SILT is as simple as using the Contour control, which allows users to toggle between highpass, flat, and lowpass curves in the pre-tube EQ stage, which makes adapting to different amps, pedal combinations, or pickup styles less of an undertaking than with a traditional fuzz.

The SILT operates at 9v to 12v, with a higher power option to allow users to supercharge their fuzz. Running at 12v unlocks an extra gain boost, pushing the fuzz to a deeper, more electrified version. Maintaining the integrity of original tone is more achievable with a true bypass circuit, ensuring the players’ guitar gets to use its natural voice to create a harmonic fuzz sound.

This fuzz is as versatile as they come, featuring a Volume, Tone, Gain, Contour, Bypass Switch, and Harmonic Switch. Crafting output tone is made possible with the lowpass/highpass tilt tone control, and control of the input gain can range from a slight crunch to full-blown fuzz.

SILT is board-friendly, featuring a 1/4″ cable input and output jacks, center negative power supply ranging from 9v to 12v, and a minimum current of 300mA.
