How It Works
Technical view
The main branch high-passes the input and drives it into a tanh fuzz stage, while a second branch full-wave rectifies the signal, high-passes it again, low-passes the result, and blends it back in as an upper-octave texture. `tone` currently affects both the strength of that octave branch and the final high shelf, while the shared `bias` control is declared but unused in this preview.

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
Parallel fuzz and rectified upper-octave branch with post-mix 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
- main high-passed tanh fuzz branch
- rectified octave-up branch
- parallel branch sum
- 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 main tanh fuzz branch.
- tone: Raises the level of the rectified octave branch and adjusts the post-fuzz high shelf.
- bias: Declared in the shared control set but unused in the current preview code.

Controls
Audible controls in this DSP
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.
Applies final post-effect level trim after DC blocking and before the output limiter.
Matches loudness without changing the actual fuzz structure.
Raises the gain feeding the main tanh fuzz branch.
Adds more saturation and sustain to the fundamental fuzz voice.
Raises the level of the rectified octave branch and adjusts the post-fuzz high shelf.
Brings out more octave splash and top-end bite at higher settings.
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 an octave branch but does not use the shared bias control.
