Aquamarine5 includes an astoundingly precise recreation of an American ultra-rare passive equalizer from the '50s. And when we say 'ultra-rare' we say it for a reason. The owner of this unit, which was sampled in Berlin, explained how only a few of these beasts - possibly less than 5 - can still be found in good working order. We don't know how the others sound like compared to the one we are bringing you this time and if they present any differences due to component variations or simply due to maintenance. What we know, though, is that the DNA of Aquamarine's EQ is the same as the one found in its hardware counterpart.

We have elevated the Aquamarine Compressor to new heights with the release of its 5th version, incorporating new features that enhance its accuracy and integrating it with our cutting-edge Hyper technology.
