Aurora DSP’s guitar/bass front-end boost and overdrive plugin “GRIM3” is now available for free!
In this article, we cover the giveaway details and an overview of GRIM3. Be sure to check it out.
1. What Is Aurora DSP “GRIM3”?
GRIM3 is a boost/overdrive plugin you place in front of an amp or amp simulator to make guitar and bass sounds tight and aggressive. It is a plugin model of the “GRIM3” overdrive pedal made by This Heavy Earth. Rather than serving as a standalone distortion, its main focus is to tighten the input stage (front end) of an amp and keep modern high-gain tones tight. It handles everything from a transparent clean boost, to a boost that warms up the tone, to saturated overdrive, tightening up your riffs for an aggressive guitar and bass sound.
Key Features
- A boost/overdrive plugin used in front of an amp or amp simulator (covers everything from clean boost to saturated drive)
- Tight: a pre-gain low-end control that cuts low frequencies before the gain stage to tighten the input
- Low / High: low-end and high-end EQ shaping
- Blend: mixes the dry signal with the driven signal (adjusts the balance with the original sound)
- Bite: a control that shifts the midrange focus
- GAIN (amount of distortion) / Level (final output level)
- Designed for chugging riffs, focused on modern high-gain guitar, bass layers, and riff creation
