    Really nice midrange. Both high and low mid boosts combined with the headroom knob can make a sound really jump out of the speakers.

    The Natalus is a wonderfully unique emulation of Harris Doyle Console EQ. Packed with vintage-y passive inductor/transformer/Class-A goodness, The Nat offers amazing analog warmth and musicality in a highly controllable and effective package that Brainworx does so right. Drive the Peak Level circuit hard to heat things up or pull it back to keep it smooth and pristine – the tonal possibilities are endless. And with Brainworx's Patented TMT technology and use of M-S for width control, you can be assured that modern control of vintage tonality is at your fingertips. Make your music great!

    Surgical EQ's should be clean and transparent, but I like my character EQ's to have some personality! The Natalus sounds sweet - not in a "too much candy" way, but flattering and pleasant. Perfect for enhancing a vocal or a whole track, put the Natalus on anything you want to sound gorgeous.
