Crushed Bias Fuzz

Coarsely stepped fuzz that currently uses the same quantized core as Alias Fuzz.

The current path is identical in structure to Alias Fuzz: a single tanh fuzz stage feeds a quantizer, then a post-fuzz high shelf shapes the result. In other words, the crushed character currently comes from the quantization stage rather than from a distinct voltage-starve or transistor-bias circuit.

How It Works

Technical view

The current path is identical in structure to Alias Fuzz: a single tanh fuzz stage feeds a quantizer, then a post-fuzz high shelf shapes the result. In other words, the crushed character currently comes from the quantization stage rather than from a distinct voltage-starve or transistor-bias circuit.

Signal Path

Compiled preview chain

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.

Preview source

Effect core

Single-stage fuzz followed by amplitude quantization and post-fuzz 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
  • single tanh fuzz stage
  • amplitude quantization
  • 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 initial tanh fuzz stage.
  • tone: Adjusts the post-fuzz high shelf after quantization.
  • bias: Sets the quantization resolution after clipping.

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 initial tanh fuzz stage.

    Adds more sustain and density before the crushing stage.

  • tone

    Active

    Adjusts the post-fuzz high shelf after quantization.

    Keeps the stepped edge darker or lets more brittle top-end through.

  • bias

    Active

    Sets the quantization resolution after clipping.

    Lower values make the output rougher and more obviously stepped; higher values smooth it out.
