"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!"

Multi-platinum Mixer

"It’s absolutely gorgeous sounding. The first plugin, in my opinion to nail the proper API sound."

Joe Carrell

11x GRAMMY-nominated Producer/Mixer

"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."

The Nashville EQ Legend.

Bring the legendary tone of the API 550A to your DAW with BB 55A. Modeled from the console EQs in Blackbird Studios B and D, it delivers the bold punch, warmth, and proportional-Q precision that made the original a studio icon. Switch between stepped and continuous gain controls for vintage feel or modern precision—all with the unmistakable sound of Nashville’s finest API desks.

Three Bands Of Greatness

Just like the hardware, the BB 55A features three fully selectable frequency bands with ±12dB of boost or cut. Its proportional-Q design keeps your EQ moves musical and natural at gentle settings, while tightening up for punch and focus as you push it harder.
