Official effect

Hard-Clip Distortion

Cascaded clipping with reinforced lows and upper mids for tighter attack and more modern bite.

After the shared stereo preview source and pre-EQ cleanup, this version drives the signal through a hotter low shelf, a stronger 930 Hz emphasis, and two back-to-back tanh stages instead of one. The extra saturation stage and higher drive multiplier clamp transients harder, while the post-drive high shelf lets `tone` recover brightness or keep the top end controlled.

Signal Path

Compiled preview chain

Preview source: An internally generated picked-string phrase is widened to stereo with a short right-channel delay and small left/right EQ offsets before it enters the distortion core.

Preview source

An internally generated picked-string phrase is widened to stereo with a short right-channel delay and small left/right EQ offsets before it enters the distortion core.

Effect core

Dual-stage tanh clipping with more aggressive pre-drive low / mid shaping and wider post-drive brightness control.

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
  • heavier low-shelf and 930 Hz contour boost
  • 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 clipped distortion path.
  • output_gain_db: Trims the final level after the distortion path has been DC-blocked.
  • drive: Raises the input level into both tanh stages, with the first stage receiving the larger boost.
  • tone: Adjusts the post-drive high shelf after the cascaded clipping stages.
  • contour: Pushes both the low shelf and the 930 Hz emphasis ahead of clipping.

Code-backed analysis

The generated description is tied to the active helper blocks and routing found in the current DSP.

Controls

Audible controls in this DSP

  • mix

    Active

    Blends the clean stereo preview source with the clipped distortion path.

    Lower values retain more dry articulation; higher values commit to the harder clipped sound.

  • output_gain_db

    Active

    Trims the final level after the distortion path has been DC-blocked.

    Sets overall loudness without changing how hard the clipping stages are driven.

  • drive

    Active

    Raises the input level into both tanh stages, with the first stage receiving the larger boost.

    Adds denser clipping, more sustain, and stronger transient flattening.

  • tone

    Active

    Adjusts the post-drive high shelf after the cascaded clipping stages.

    Restores top-end attack for aggressive bite or keeps the distortion darker and tighter.

  • contour

    Active

    Pushes both the low shelf and the 930 Hz emphasis ahead of clipping.

    Adds heft and upper-mid focus so the distortion feels tighter and more assertive.

Analysis

Code-derived notes

Reviewed against the current DSP. This patch uses the same demo phrase and output stage as the other first-pass drive previews, but it is the first of the group to use two explicit saturation stages in series.

Each effect page uses the same generated description pipeline and compiled waveform preview assets.

Transparent Overdrive

Keeps the dry attack intact while adding a broad low-mid lift and light tanh saturation for edge-of-breakup push.

View How It Works

Amp-Like Overdrive

Mid-forward soft clipping tuned to feel more like a pushed amp stage than a flat clean boost.

View How It Works

Tape Preamp

Low-gain tape-style saturation with added weight in the lows and a deliberately softened top end.
