Detail 01
12AU7 tube drive
The pedal’s fuzz drive is generated by an internal 12AU7 tube section.

Independent shopping perspective
The red Walrus Audio Silt combines a 12AU7 tube-driven fuzz section with a Harmonic mode that places octave-like overtones ahead of that drive. Its range begins with distortion-like crunch and extends into fuller saturation. Use the Contour control’s high-pass, flat, and low-pass pre-tube curves to change the fuzz texture around different pickups. The pedal operates at 9V, with 12V offering extra gain. When it is switched off, the true-bypass circuit keeps the core guitar signal uncolored.
