Official effect

Big-Box Fuzz

Sustaining full-band fuzz with a mid-focused center and smoother top end than the gated or quantized variants.

The current patch high-passes the input, slams it into one biased tanh stage, then shapes the clipped result with a broad 980 Hz peak and a post-fuzz high shelf. This is effectively the shared reference core for several vintage-leaning fuzz names in the current library, with `bias` changing clipping asymmetry before the distortion stage.

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.

    Adds more sustain, compression, and fuzz thickness.

  • tone

    Active

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

    Moves the fuzz between a flatter wall and a brighter, more projecting voice.

  • bias

    Active

    Offsets the waveform before clipping.

    Changes how evenly the fuzz compresses and how ragged the clipping edges feel.
