How It Works
Technical view
This preview also uses the Tape Preamp signal path: high-pass cleanup, a heavy low shelf, modest 930 Hz shaping, one gentle tanh stage, and a restrained post-drive high shelf. It behaves as a broad thickener today rather than a uniquely transformer-colored saturation model.

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
Gentle single-stage tanh saturator currently sharing the Tape Preamp core with strong low-shelf thickening.
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 thickening and modest 930 Hz contour shaping
- gentle single tanh saturation stage
- restrained post-drive high-shelf compensation
- 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 low-gain saturator path.
- output_gain_db: Applies final level trim after the DC blocker and before the limiter.
- drive: Raises the input multiplier into a gentle single tanh stage.
- tone: Adjusts a restrained post-drive high shelf.
- contour: Pushes more low shelf and a modest 930 Hz contour before saturation.

Controls
Audible controls in this DSP
Blends the clean stereo preview source with the low-gain saturator path.
Lower values retain more unaffected attack; higher values emphasize the thicker preamp color.
Applies final level trim after the DC blocker and before the limiter.
Matches loudness without changing the amount of saturation.
Raises the input multiplier into a gentle single tanh stage.
Adds harmonic density and soft compression without moving quickly into heavy distortion.
Adjusts a restrained post-drive high shelf.
Lets the saturator stay dark and dense or open slightly for more presence.
Pushes more low shelf and a modest 930 Hz contour before saturation.
Adds weight and low-mid body to the preamp voice.
Analysis
Code-derived notes
Reviewed against the current DSP. The current preview shares the same active low-gain thickener core as Tape Preamp and is not yet a differentiated transformer-model path.
