WELCOME TO SKY ONION MASTERING

Since 2008 I’ve helped an inspiring variety of musicians make great sounding records. My extensive engineering experience and lifelong music fandom guides me in enhancing recordings of any genre.

At the heart of the studio is a custom built speaker system which has been painstakingly tuned for accuracy and translation. A cutting-edge lacquer mastering lathe delivers beautiful results on vinyl. Analog and digital processing equipment has been selected with utmost care and no expense spared. I’m ready to work with anyone, from first timers to seasoned professionals. Let’s work together on your next release. - Gus Elg, engineer
