Official effect

Fuzz Synth

Parallel bright fuzz and saturated low-band support for a thicker, more synth-like composite voice.

There is no separate oscillator here; the synth-like feel comes from splitting the input into a high-passed fuzz branch and a low-passed support branch with its own saturation amount. After those branches sum, `tone` reshapes the result with a 1.2 kHz peak and a high shelf, while `bias` increases the saturation feeding the low-band support layer.

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

Parallel bright fuzz branch and low-band saturation branch with mid-peak and high-shelf tone shaping after the sum.

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-passed tanh fuzz branch
  • low-passed support branch with separate saturation
  • parallel branch sum
  • 1.2 kHz peak shaping
  • 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 the gain feeding the bright high-passed fuzz branch.
  • tone: Adjusts the 1.2 kHz peak EQ and the post-fuzz high shelf after the two branches recombine.
  • bias: Raises the saturation amount on the low-passed support branch.

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 the gain feeding the bright high-passed fuzz branch.

    Adds more edge, sustain, and upper-band saturation.

  • tone

    Active

    Adjusts the 1.2 kHz peak EQ and the post-fuzz high shelf after the two branches recombine.

    Moves the combined voice from thicker and darker toward brighter, more nasal projection.

  • bias

    Active

    Raises the saturation amount on the low-passed support branch.

    Adds more low-band thickness and compressed synth-like body under the main fuzz.

Analysis

Code-derived notes

Current implementation gets its synth-like behavior from parallel filtering and saturation, not from oscillator generation.
