How It Works
Technical view
The current signal path is the same one used by Gated Fuzz and Sputter Fuzz: high-pass cleanup, a hot biased tanh stage, then a clamp-style gate driven from a smoothed amplitude follower before the final high shelf. Its ripping character comes from that hard cutoff behavior rather than a separately tuned velcro-specific circuit.

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 hits the fuzz core.

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 hits the fuzz core.
Effect core
Hard-gated fuzz that clips first, then applies a smoothed amplitude gate before final high-shelf tone shaping.
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
- biased tanh fuzz stage
- smoothed amplitude gate
- post-fuzz 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 untouched stereo preview source with the fuzzed path after the effect core.
- output_gain_db: Applies final post-effect level trim after DC blocking and before the output limiter.
- fuzz: Raises both the gain feeding the fuzz stage and the multiplier that sharpens the gate response.
- tone: Adjusts the post-fuzz high shelf.
- bias: Shifts the pre-clip offset and changes the threshold used by the smoothed amplitude gate.
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
Blends the untouched stereo preview source with the fuzzed path after the effect core.
Lower settings preserve more pick attack and clean body; higher settings push the fuzz treatment to the front.
Applies final post-effect level trim after DC blocking and before the output limiter.
Matches loudness without changing the actual fuzz structure.
Raises both the gain feeding the fuzz stage and the multiplier that sharpens the gate response.
Adds more torn-up sustain while also making the gate collapse harder.
Adjusts the post-fuzz high shelf.
Moves the ripping top end from darker and papery to brighter and more aggressive.
Shifts the pre-clip offset and changes the threshold used by the smoothed amplitude gate.
Lower values choke the fuzz earlier; higher values leave more tail before it collapses.
