Walrus Audio Silt Harmonic Tube Fuzz 2024

13 captures of the Silt, a fuzz built around a 12AU7 tube. Recorded at 12 V (more gain and a slightly tighter response than 9 V) after the tube had warmed up for over an hour. Knob positions are clock times (12:00 = noon). CONTOUR is a 3-way EQ before the tube: UP = high-pass (less low end, tighter and more cutting), MIDDLE = flat (full range), DOWN = low-pass (darker, woollier). HARMONIC adds an octave up before the tube. TONE is a tilt EQ after the fuzz.
