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.

    In a sea of EQ options BigFreq is on the shortlist go to’s for me. It sounds musical and has a lot of vibe even when making more focused moves outside of broad stroke tone shaping moves. The Finisher saturation is the icing on the cake. Kick drums, snares, bass guitar, guitars, and vocals are usually the tracks you could find this eq on in my sessions. Just like The Arouser, more features and updates are being pushed out for this plugin and it is a great choice if you’re looking for something different from the endless run of the mill eq’s.

    I bundled this with my Arouser purchase and I’m glad I did! This EQ plugin allows me to easily get the sounds I want and the saturation is a great extra. Very useful.

    Hi, like everyone else I thought… another eq? So I delayed the purchase… Now I have it and I’m loving this very good sounding eq. Does it sound better than others? Well, that’s the wrong question… Does this eq sounds good? Yes, it sounds amazing, with all it’s versatility you can do very crazy eq curves and add some saturation if you want. For me it’s a “go to” eq. Very very good sounding. It could only improve if it has an on/off choice to see an FFT display. Empirical Labs is one of my favorite manufacturers, and now that I have all your plugins I’ll start saving for a Distressor! 🙂 Thank you very much.

    This eq sounds great and has some nice features making it useful to someone like me who already has many different EQ plugins but I would really love to see a real time analyzer added!

  5. Matt

    I didn’t think I needed another EQ but the way I can shape peaks and dips is really valuable and as far as I know, only available on this plugin. It’s a great tool to have in my collection. As others have mentioned, the DS section of the Lil FrEQ would be a great addition, and so would the HF limiter function. Thanks Empirical Labs!
