12AU7 Tube Drive — Warmth and Harmonic Complexity

The Silt's 12AU7 tube section drives the heart of its warm, bone-rattling fuzz. This carefully selected tube adds a vintage warmth and harmonic richness to your sound, providing a unique character that sets it apart from other fuzz pedals. Experience the grit, growl, and complex textures that only a tube-driven fuzz can deliver.

Harmonic Mode — Explore Octave-Fuzz Textures

Engage the Harmonic mode to activate a frequency doubler before the drive section, adding a unique octave-fuzz character to your sound. This mode creates crisp, octave-like harmonics that add a new dimension to your leads and chords. Experiment with your guitar's tone knob to further shape the harmonic content and discover a world of sonic possibilities.

Contour Control — Precision Tone Sculpting

The Silt's Contour control allows for precise tone sculpting, offering a three-way toggle switch that selects between high-pass, flat, and low-pass curves in the pre-tube EQ stage. This versatile control allows you to fine-tune your fuzz tones to match your playing style and guitar/pickup combination. Whether you're seeking searing leads or wooly rhythms, the Silt adapts to your needs with precision.

9V-12V Operation for Enhanced Gain

The Silt is designed for operation at 9V or 12V, providing an extra gain boost when running at 12V. This allows you to push the pedal's limits and explore even more extreme fuzz tones, adding another layer of versatility to this already powerful pedal.
