Pitch Fuzz

Biased high-gain fuzz that currently uses the same mid-shaped vintage core rather than adding a dedicated pitch stage.

The current implementation matches the same biased single-stage fuzz used by Germanium Fuzz, Silicon Fuzz, Tone-Bender Style Fuzz, and Big-Box Fuzz: high-pass cleanup, tanh clipping with DC offset, a broad 980 Hz contour, and a post-fuzz high shelf. In other words, it is presently a naming variant of that core rather than a pitch-tracking or pitch-shifted fuzz design.

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

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

Single-stage biased fuzz with pre-drive high-pass cleanup, 980 Hz mid contouring, 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
  • high-pass cleanup
  • single biased tanh fuzz stage
  • broad 980 Hz 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 input multiplier feeding the single fuzz stage.
  • tone: Adjusts both the 980 Hz peak EQ and the post-fuzz high shelf.
  • bias: Offsets the waveform before 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 input multiplier feeding the single fuzz stage.

    Increases sustain and saturation density.

  • tone

    Active

    Adjusts both the 980 Hz peak EQ and the post-fuzz high shelf.

    Changes how forward the mids and upper harmonics feel after clipping.

  • bias

    Active

    Offsets the waveform before clipping.

    Changes clipping symmetry and the rasp of the fuzz texture.

Analysis

Code-derived notes

Current implementation does not add pitch tracking or pitch shifting; it shares the same biased vintage-fuzz topology as Germanium Fuzz, Silicon Fuzz, Tone-Bender Style Fuzz, and Big-Box Fuzz.
