Reproduction of sound. Sunday Afternoon Is Infinity Bender brings back the fuzz sound of the mid-1960s, which had a huge impact on many fuzz pedals.  A thick and warm fuzz tone with a center of gravity near the low to mid. It is even heavier than the fuzz face, and the higher the fuzz, the higher the edge.  It is a characteristic that is exactly like a tone vendor. The SMOOTH knob allows you to adjust the fuzz fluff, smoothness, and tone balance.  When combined with a clean amp, FUZZ will have a “fuzz-like” tone when set high. If you combine it with a tube amp, let's make a sound with FUZZ starting around 12 o'clock.  You can also lower the FUZZ and bring the pickup to the front to create an intensely warm and soft tone.  Specifications Control VOL: Adjusts the overall volume.  FUZZ: Adjusts the strength of distortion.  SMOOTH: Adjusts the balance, warmth, and edge of the tone.
