Hey there fellow musicians!
I'd like to start this one off by discussing recording, mixing and mastering techniques. There are obviously a gazillion ways accomplish a fantastic mix, but it's always nice to share knowledge and see if one can improve their skills!!
Here's a quick trick that will fatten any vocals up no matter what mic/pre/comp chain you are using:
Add distortion. One of my favorite plug-ins to thicken up and control vocal dynamics is the SoundToys Devil-Loc Deluxe. Toss it on an aux track and get ready to be amazed. Actually, it works great on anything. Even a master buss.
Too much distortion will of course kill a mix, but just enough will work wonders.
Good mixing to you!
