Official effect

Gated Fuzz

Hard-gated fuzz that slams shut on the note tail for abrupt, sputtering decay.

After high-pass cleanup and a hot biased tanh stage, this patch multiplies the signal by a clamp-based gate driven from a smoothed absolute-value envelope. `fuzz` increases both the pre-clip gain and the gate steepness, while lower `bias` raises the gate threshold so the tail chokes off sooner.

Preview source

An internally generated picked-string phrase is widened to stereo with a 19-sample right-channel delay and slight left/right shelf-EQ offsets before it hits the fuzz core.

Effect core

Hard-gated fuzz that clips first, then applies a smoothed amplitude gate before final high-shelf tone shaping.

Signal path

The static waveform and the live player both reflect this compiled signal chain.

  • internal picked-string demo phrase
  • stereo spread with a short right-channel delay
  • high-pass cleanup
  • biased tanh fuzz stage
  • smoothed amplitude gate
  • post-fuzz high-shelf tone shaping
  • dry / wet mix
  • DC blocker
  • output gain trim
  • final tanh limiter

Controls that matter

These are the currently active controls detected in the FAUST source for this effect.

  • mix: Blends the untouched stereo preview source with the fuzzed path after the effect core.
  • output_gain_db: Applies final post-effect level trim after DC blocking and before the output limiter.
  • fuzz: Raises both the gain feeding the fuzz stage and the multiplier that sharpens the gate response.
  • tone: Adjusts the post-fuzz high shelf.
  • bias: Shifts the pre-clip offset and changes the threshold used by the smoothed amplitude gate.

Code-backed analysis

The generated description is tied to the active helper blocks and routing found in the current DSP.

Controls

Audible controls in this DSP

  • mix

    Active

    Blends the untouched stereo preview source with the fuzzed path after the effect core.

    Lower settings preserve more pick attack and clean body; higher settings push the fuzz treatment to the front.

  • output_gain_db

    Active

    Applies final post-effect level trim after DC blocking and before the output limiter.

    Matches loudness without changing the actual fuzz structure.

  • fuzz

    Active

    Raises both the gain feeding the fuzz stage and the multiplier that sharpens the gate response.

    Adds more fuzz density and makes the gate clamp down more aggressively.

  • tone

    Active

    Adjusts the post-fuzz high shelf.

    Makes the gated splatter darker and choked or brighter and more cutting.

  • bias

    Active

    Shifts the pre-clip offset and changes the threshold used by the smoothed amplitude gate.

    Lower values make the tail choke and sputter earlier; higher values let notes hang on longer.
