How It Works
Technical view
The drive core uses the standard single-stage soft clip and pre-drive EQ, then runs the result through `quantize` before the normal post-drive high shelf. Because the quantizer depth is tied to `tone`, the control now affects both the bit reduction density and the final top-end shelf.

Signal Path
Compiled preview chain

Preview source

Effect core
Single-stage soft clip followed by quantization for bit-reduced drive texture.
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
- single tanh saturation stage
- quantization 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 both the quantizer step count and the post-drive high shelf after the bit-reduction stage.
- 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 both the quantizer step count and the post-drive high shelf after the bit-reduction stage.
Changes how coarse the digital breakup feels while also shifting the top-end brightness.
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 differentiated by the explicit quantization stage after saturation, not by a completely different underlying EQ chassis.
