GRRR Black Friday pricing is 79% off, which puts this Thenatan Audio growl designer at $10 until Nov 19, 2026.
GRRR is a multi-effect plugin for Mac and Windows that turns basses, vocals and drums into aggressive, distorted versions of themselves. The maker calls it a beat-reactive creature rather than a plain distortion plugin.
It listens to the incoming track and reacts in real time. The growl hits on the transients and slurs in the gaps between them.
The maker pitches it at modern bass-music producers. Feed it a flat 808, a thin vocal or a dull loop, and the engines add teeth.
The beat-reactive engine detects each hit and drives the growl in sync with the track. The maker names dubstep, drill, new hip-hop, trap, EDM and riddim as target genres.
GRRR has four engines, each controlled by its own knob. TRASH folds, crushes and ring-modulates the signal, adding a rattling throat texture, all from one control. TALK is a beat-triggered vowel mouth that can run up to 4x faster on hits. WUB is a resonant wobble filter offering broader, deeper sweeps. SCREECH is a metallic riddim laser that glides from a low growl up to a high scream. Two master knobs then shape all four engines together. SUB adds octave-down weight underneath the sound.
DENSE scales drive, sweep depth, resonance and gating across every engine together. Push it up and all four racks get nastier in one move.
Each rack also has its own Mix and Bypass. You can blend engines in parallel or flip one off to A/B the result.
The maker says you can dial anything from subtle grit to total destruction, and every engine follows your input as it plays.
GRRR ships with 20+ presets. They cover bass growls, vocal monsters, drum destruction and riddim lasers.
Load one, tweak the rack knobs and the master controls, and bounce the result. If you'd rather build from zero, the one-knob-per-engine layout keeps the signal chain short.
If you want a growl on a sub, a vocal chop or a drum bus without stacking several separate plugins, this is the job GRRR is built for.
Yes. The GRRR Black Friday deal from Thenatan Audio takes 79% off, bringing the plugin to $10. The offer ends Nov 19, 2026.
GRRR has four racks. TRASH covers wavefolding, decimation, ring-mod and throat rattle. TALK is a vowel-speaking mouth that accelerates up to 4x on hits. WUB is a resonant wobble filter. SCREECH is a metallic riddim laser.
The maker built it for basses, vocals and drums. Its beat-reactive engine follows the incoming track in real time, so it can add growl to an 808, a vocal or a drum loop. 20+ presets cover each of those sources.
SUB adds an octave-down weight to the sound. With DENSE, a single control adjusts how much saturation, filter movement, resonance and gate action each of the four engines applies. Each rack also has its own Mix and Bypass for blending and A/B comparison.
