I haven’t read the rules about posting commercial (well this is semi-commercial self promotion) so moderators feel free to delete if self-promotion is a problem.
I’ve actually been mastering releases for 20 years or so, mostly for friends but some commercial releases.
I mention this if anyone wants mastering done. I charge for commercial releases, but accept donations for stuff like bandcamp self releases.
Why might you want someone to master your releases? 1. A fresh set of ears making final decisions about levels and tonal balance. 2. I probably have better in-the-box tools than you do. I have a UAD-2 so I have things like virtual Fairchild 670 compressor and Manley Massive Passive EQ. 3. I’ve done a ton of mastering, and I think I have a good record of satisfied friends and customers.
As an example of my work, I mastered this project. I about lost my mind, but I did it.
DM me if this is something you’re interested in.
