Official effect

Torn Speaker

Mid-bottleneck fuzz that constricts bandwidth before clipping to mimic a damaged speaker voice.

Before saturation, this patch narrows the input with a band-pass filter whose center shifts upward with `tone`, then drives that restricted band into a tanh stage and a dark high shelf. The result is more speaker-cone bottleneck than full-range fuzz, and the shared `bias` control is currently declared but unused.

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

Band-pass-constricted fuzz with clipping after the bandwidth choke and a dark post-fuzz high shelf.

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
  • pre-fuzz band-pass bottleneck
  • single tanh fuzz stage
  • dark 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 clipped band-passed signal.
  • tone: Moves the band-pass center upward and also adjusts the final high shelf.
  • bias: Declared in the shared control set but unused in the current preview code.

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 clipped band-passed signal.

    Pushes the narrow speaker-like band into denser saturation.

  • tone

    Active

    Moves the band-pass center upward and also adjusts the final high shelf.

    Shifts the damaged-speaker emphasis higher or lower while also changing brightness.

  • bias

    Active

    Declared in the shared control set but unused in the current preview code.

    Changing it currently has no effect on the sound.

Analysis

Code-derived notes

Current implementation uses the tone-controlled pre-fuzz band-pass choke but does not use the shared bias control.
