How It Works
Technical view
This patch uses the familiar high-pass and pre-EQ staging, then feeds a gentle tanh stage into `ef.wavefold` before the post-drive high shelf. The fold amount scales with `drive`, so higher settings add sharper upper harmonics than the plain soft-clip overdrives.

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
Single-stage soft clip feeding a wavefolder for brighter folded overtones.
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
- low-shelf and 930 Hz contour shaping
- gentle tanh saturation stage
- wavefolder 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 file is genuinely differentiated from the surrounding overdrives because it adds an explicit wavefolding stage after saturation.
