Shocking vacuum tube fuzz sound A collaborative project with tube expert Jim Hagerman, SILT was created specifically for those seeking a harmonically rich fuzz. Featuring an analog drive circuit with the distinctive warmth of a 12AU7 tube, SILT allows you to explore unique and wild sounds. This 2-in-1 fuzz pedal creates an incredibly rich fuzz tone that's perfect for chords and rhythmic parts with the Harmonic switch. -12AU7 Tube Drive The 12AU7 tube section produces a warm, chunky fuzz sound. This sonic fossil has been unearthed, enveloping the sound in amber warmth while providing the grit, growl, and harmonically complex textures that tube fuzz is known for. -Harmonic Mode Harmonic Mode acts as a frequency doubler before the drive section of the pedal, creating a crisp, octave-like sound that adds a unique edge to lead tones. Try it with your guitar's tone knob turned off. -Contour Control The Contour control precisely refines your fuzz tone for a wide range of tones. The pre-tube EQ stage switches between high-pass (up), flat (mid), and low-pass (down) curves. This is especially useful when switching between different pickup styles. Whether you're looking for searing leads or woolly rhythms, the Silt adapts surprisingly well to your style. -Compatible with 9V-12V power supplies The SILT is designed to run on 9V-12V, allowing you to experience even more fuzz. Running the pedal at 12V boosts the gain even further, pushing the limits of fuzz fundamentals for searing tone. 【specification】 Power supply: 9V 12V DC center negative (for adapter only) 300mA minimum・SIZESIZE:9.3cm(W)×5.8(H)×12.3(D)cm・WEIGHTWEIGHT: 362g
