"The A5 is a very welcome addition to my own mixing. All 3 of the classic eq styles in one plugin with easy access hi/lo pass filters is a big deal to me. Add the mic pre 'weight' to that and you can’t go wrong."

"I immediately go to the kick and take away a little 500 Hz and add a little 63 Hz. I’ve always loved the API Legacy console and this plugin replicates it beautifully. It sounds like I’m in D!"

The Nashville EQ Legend.

The BB 55L captures the refined power of the API 550L from Blackbird Studio’s API Legacy consoles. With four flexible bands, proportional-Q precision, and the signature punch of API tone, it delivers warmth, clarity, and control in every mix. Choose stepped or continuous gain and sculpt your sound exactly the way you want it.

Four Bands Of Greatness

With four independent bands, each offering seven selectable frequencies and ±12dB of boost or cut, the BB 55L gives you both surgical control and broad musical shaping in one intuitive interface. Its proportional-Q behavior keeps your adjustments cohesive and natural, even when pushed for bold tone sculpting.
