What amazes me the most about the API 550b is that it never fails to make any track better than I think it can get! The Proportional-Q is a great feature that really sweetens up a mix, but still allows me the room to really sculpt my sound in the studio.
The API 550b is the staple sound of my studio. This EQ has a no-nonsence attitude that makes it a joy to use. There's no fumbling around to find frequencies — operation is very cut and dry — and the 550b packs serious punch. There's a reason this EQ is an absolute classic!
This is the one
Been using these at studios for years and always wanted one for my own. Sounds great, easy to use, repeatable settings. Just get it, you'll use it on everything.
Better than Awesome?
I really didn't want to spend this much money on an eq when there are so many eq's out there. I heard it was great so finally just got it any way, thinking by the best and don't look back. I won't! This is the most musical eq I've ever used. It it is so detailed and instead of just boosting frequencies you like, it is like musical surgery getting rid of the nasties in your track. Used in conjunction with a good preamp (I chose the 512c) you can get your microphones dialed in and sounding so wonderful with just the details you want. This unit give me the control on the way into my DAW so that I don't have to do much if any eq'ing in software. I've used it with different mics, and it brings out the greatness in all of them. I will never sell this eq, it's just that good.
you get what you pay for
Let's face it people, API has been the "go to" people for great professional sound since before I started giging. I'm happy that other companies are producing 500 series products with success, but it's not API. I've been playing off api products since the early 90's in studios and have had great success with these units. I have two of these beauties in my lunchbox that I use for my bass stack (you read it right) for live sound. Don't be intimidated by the looks or price. These units are very easy to set, they sound so wonderful and once you play off this you will be chasing this sound untill you buy a pair! I know because I did. I chased this sound to no avail. As far as price goes my bass stack sounds like God and I know it. I do not need to improve my sound anymore or look for other products that claim they do just as good if not better. When you get a bassist that loves thier sound as much as I do it's just the right thing to do at any price. I will play through these for the rest of my life and will never have any regretts.
