I know an EQ is great when I simply put it on a track, don’t make any adjustments, and the track instantly sounds better. That’s what the Q American Series equalizers do for me! Very smooth, transparent highs, clear defined mids, punchy and warm low end without mud. Knobs and faders have nice ballistics and the EQ’s “behave” like their much sought-after hardware equivalents. And they look like 500 series “lunchbox” units too – a nice psychological benefit. Great product!
I have been mixing several projects with Q American Series and I’m pretty much loving them. One of the projects I’m working on had a very unpleasantly and poorly recorded, bass heavy sounding, male vocal. I chose some other EQs to remove that low end. I wasn’t quite happy with either of my choices, then I reached for QA, just to check how QA will handle it. And I was pleased to hear how it nailed the task! Just one knob rotation and boom, that nasty low-end crap is gone. Great Sound!

Volko Audio hit a home run with the QA and QB. It surpassed all my expectations and then some. Finally found a plugin version of my favorite API EQs to compliment the hardware.
