Aurora DSP has introduced a free overdrive effect plugin based on the This Heavy Earth Effects pedal.
Designed primarily as a front-end boost for amplifiers and amp simulators, Grim3 provides controls for tightening low frequencies, shaping the overall tone, and enhancing attack and clarity.
Built for chugging, GRIM3 can work as a transparent clean boost, a tone warmer, or a saturated overdrive that tightens the input stage before your amp. The control set lets you cut boom, add bite, balance dry attack with driven weight, and push the output into the exact amount of impact your mix needs.
Grim3 features
- Tight control for low-end shaping before the gain stage.
- Low and High EQ controls.
- Blend control for mixing dry and processed signals.
- Bite control for additional midrange presence and attack.
- Output level adjustment.
- Suitable for guitar and bass applications.
Grim3 is available to download in VST3, AU and AAX formats for Windows and macOS.
An expanded collection of tones is available in the This Heavy Earth Suite, which features additional pedals, an amplifier, and a broader range of sound-shaping tools designed for modern guitar and bass production. The suite is available to purchase at an early access price of $139 USD.
