So, I gave them my most recent track to be "studio," processed. All of this was done free of charge.

I like the compression on the kick, the bass also sounds cleaner and the gate effect on the snare is nice. However, the other tracks don't sound so great. In fact, they sound a lot worse than the original.
It has me thinking, is it worth it?
Obviously, I'm used to listening to the track the way it was, but isn't that important?
