Since a majority of my chain consists of analog gear, I'm very selective when it comes to which plugins I use. bx_refinement has definitely been a great addition to my arsenal.
This plugin is the coolest and strangest tool we've come across. It works wonders on harsh overhead and guitar tracks that we've had come in for mixing. In a mastering setting, it really helps clear up the harsh frequencies in a way that no other tool can. Finding new ways to put this thing to use every day!
I've been an analog based mastering engineer for the past 20 years. When people used to ask what plugins I used, I would always respond with "Plugins? I don't use no stinking plugins." And then Brainworx came into my life. The bx_refinement tool is not for people looking for wow factor on a mastering buss. But it did wow me. Its subtle way of de-harshing, smoothing, and making things smooth and cohesive deserves a "wow." It brings the round and warm back into a master that is different than traditional EQ and compression. The bx_refinement is a great tool for for today's over-processed and harsh tracks. Bravo, Brainworx.
I love using the BX Refinement plugin near the end of my Pro Tools vocal buss to tame harshness and add presence with the saturation knob.
