Not really sold on this. I personally like to avoid EQ “at the end” of the process, because it always feels like you are fixing something that you should just fix somewhere else. (So why not just hear it and go fix it?)
That is not so much a criticism of the bx_Masterdesk as it is of the process/workflow. I’m just not a fan of doing a lot of tonal changes after the mix is completed. I know there are mixes that are screwed up and might need that. Don’t be that person. (Disclaimer: I’m not a mastering engineer.) Also, these all-in-one solutions seem to be more about trend than function. You might argue it’s about economics, but this is a UAD plugin, ok?!
As you can see in the graph, it really cleans out the high and low end though! You don’t even have to do anything but insert it on channel. It also bumps the highs slightly. So basically, don’t touch anything, and it probably will add a little analog-ness to your recording. (Again, I’m not a mastering engineer.)
