The FRG-EEE Rack Extension plug-in is a modern four-band equalizer consisting of low and high shelving EQ wrapped around two parametric bands.
The FRG-EEE equalizer (aka 'froggy') packs a punch at the low and high end using a shelving EQ technique we call frequency resonant gain (FRG). This approach gives the FRG-EEE a little extra near the selected shelving frequency for, well, a little extra. The two parametric bands have a reasonably tight (but musical) Q, and wide frequency ranges.
The FRG-EEE is great for drums, guitars, vocals, synths, and perhaps ukuleles. Note how its low shelf EQ is great on kick drum boosting, while also excellent at vocal plosive reduction when cutting. The parametric bands are great for sculpting the mid-range. The frequency resonant gain in the high shelf EQ can make tracks a tad crispy, so be careful. Unless you like crispy.
