How It Works
Technical view
Compared with the other soft-clip overdrives, this one backs the pre-drive low shelf down and pushes the 930 Hz peak much harder before the same single tanh stage. That shifts more energy into the midrange, so `contour` acts more like a real hump control while `tone` still manages the post-drive high shelf after saturation.

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
Single-stage tanh overdrive with restrained lows and a deliberately exaggerated 930 Hz mid emphasis.
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
- reduced low-shelf lift and stronger 930 Hz mid emphasis
- single tanh saturation 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 soft-clipped overdrive path.
- output_gain_db: Applies final post-effect level trim after the DC blocker.
- drive: Raises the level feeding the single tanh saturation stage.
- tone: Controls the post-drive high shelf after saturation.
- contour: Changes the low shelf and 930 Hz emphasis ahead of clipping.

Controls
Audible controls in this DSP
Blends the clean stereo preview source with the soft-clipped overdrive path.
Lower values keep more dry articulation; higher values favor the overdrive voice.
Applies final post-effect level trim after the DC blocker.
Balances loudness without changing how the clipping stage behaves.
Raises the level feeding the single tanh saturation stage.
Moves the patch from light breakup toward thicker, more compressed overdrive.
Controls the post-drive high shelf after saturation.
Brightens the clipped signal for more edge or smooths it for a darker voice.
Changes the low shelf and 930 Hz emphasis ahead of clipping.
Pushes more body or midrange into saturation, changing how focused the overdrive feels.
Analysis
Code-derived notes
Reviewed against the current DSP. This is one of the clearer genuinely differentiated single-stage overdrives because the pre-drive mid emphasis is much stronger than the neighboring files.
