How It Works
Technical view
This preview uses the same active path as Hard-Clip Distortion: stronger low-shelf feeding, restrained 930 Hz emphasis, two tanh clipping stages, and a broad post-drive high shelf. It is already aggressive, but the current code does not yet introduce a separate chainsaw-specific upper-mid or filter structure beyond that shared distortion core.

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 reaches the active drive path.

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 reaches the active drive path.
Effect core
Dual-stage tanh distortion currently sharing the Hard-Clip Distortion core for aggressive saturation.
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
- stronger low-shelf boost and restrained 930 Hz emphasis
- first tanh clipping stage
- second tanh clipping stage
- post-drive 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 clean stereo preview source with the dual-stage clipped distortion path.
- output_gain_db: Trims the final level after DC blocking and before the limiter.
- drive: Raises the level feeding both tanh clipping stages, especially the first one.
- tone: Controls the wide post-drive high shelf after the cascaded clipping stages.
- contour: Adjusts the low shelf and restrained 930 Hz push ahead of clipping.

Controls
Audible controls in this DSP
Blends the clean stereo preview source with the dual-stage clipped distortion path.
Lower settings keep more dry pick detail; higher settings commit to the denser distortion voice.
Trims the final level after DC blocking and before the limiter.
Sets loudness without changing how hard the internal clipping stages are hit.
Raises the level feeding both tanh clipping stages, especially the first one.
Adds denser saturation, more sustain, and stronger transient flattening.
Controls the wide post-drive high shelf after the cascaded clipping stages.
Restores bite and attack or keeps the distortion darker and more controlled.
Adjusts the low shelf and restrained 930 Hz push ahead of clipping.
Changes how much weight and upper-mid focus gets driven into the distortion core.
Analysis
Code-derived notes
Reviewed against the current DSP. The current preview shares the same active dual-stage clipping core as Hard-Clip Distortion and is not yet independently differentiated for chainsaw-specific filtering.
