With twelve powerful sections of processing, BIG FrEQ offers the ability to create modern “flat-top” parametric shapes with an analog workflow and added controls for more tone-shaping possibilities than a typical EQ plug-in. Inspired by the precision and warmth of Empirical Labs Lil FrEQ parametric equalizer, BIG FrEQ introduces superior fine tuning controls for surgical tone shaping and a unique FINISHER section for adding organic harmonic distortion. Like the plug-in’s predecessor, the Arousor, Empirical Labs brings the soul of analog hardware to the digital realm and includes features that can not be replicated in the analog domain. As always, Empirical Labs offers new twists and functionality to their new plug-in EQ and labors over making it mindless to learn, and just plain FUN to use.


Flat Top Shapes

Create modern tone curves with the added SLOPE control on each parametric band. This fourth EQ parameter steepens the edges of the curve creating a plateau shape allowing more frequencies to be adjusted equally.

Analog Saturation

Dial in organic, tape-like saturation with the unique FINISHER section and know how much saturation is being applied with the saturation meter. 

Focus Mode

Switching on the FOCUS mode will center the selected frequency and reduce the range of FREQ knob for easy fine tuning.

More Range

Expand the range of the GAIN knob an extra 15dB by toggling the RANGE mode for more dramatic boosts and cuts.

    Love this Eq.I like most people reading this have too many plugins already.As soon as I tried the demo though I new it was something special.The interface is great having no analyser means you have to use your ears.Haven’t had to do that in a while.The knob that adds saturation is a great touch and now with the online activation makes this a no brainer.I also have the arouser which is another unbelievable plugin.Just Buy it.

    Great eq, it adds a wonderful flavor to the tracks. As usual ELI it’s a guarantee. Sounds really good, but… the five star will come when they add the local iLok authorization. No way I buy a dongle and the need of an internet connection is really a silly thing. I wanna make music everywhere (I bought a laptop for that reason) and this thing is annoying. But the eq is really, really nice.

    Excellent! My favourite Plugin EQ. I use it all the time for mixing and mastering. Just outstanding 🙂

    Been experimenting the trial for the past few days and decided to buy this plugin today as I found no excuse for not doing so. This gem went right up to my favorites, mainly because of how practical it is – it just feels that everything is in the right place (probably because it is). It is a joy to use it – it just feels and sounds right. I could go on and try to explain why I feel this way by describing each of the features that glued me to this plugin, but in the end choosing a plugin is a very personal thing. I just recommend everyone reading this to at least try it! I fell in love with it.

    TL;DR: Probably the most practical EQ I used so far – everything is in the right place. It sounds fantastic to my tastes.
