If you're looking to get your recordings mastered, there are a million options out there for just about any budget.
If you ask me based off of my experience, I would send you to Jesse Cannon at Found Soundation.
His turn around time is insane. His prices fit just about any budget. And his results speak for themselves. There is nothing better than sending him a great mix, and then getting back his master and realizing how flat everything sounded before he touched it.
Some of our favorites that he's mastered:
Arm's Length - "Everything Nice"
Cavetown - "Animal Kingdom"
Hot Mulligan - "I Won't Reach Out To You"
Mansions - "Dig Up the Dead"
Sorority Noise - "Forgettable"
SQSN - "Say It Again / What's It Like?"
I need to get my stuff mastered. Who would you recommend?
