"I loved your 'Inception' story.. about how you slowly inched the microphone closer to the artist's mouth... Instead of telling him to just switch from the mic he WANTED to use. That's genius dude.. I'm gonna use that technique and call it, 'The Marlett Sneak!'"

Mixing Engineer Producer Educator

I've been in the studio for over 25 years. Two Grammy nominations, records with Blink-182, Foo Fighters, Queens of the Stone Age — and for the last several years, a classroom full of students at MiraCosta College who reminded me every single day how much this knowledge matters.

Teaching changed the way I think about what I know. Every question a student asked was something I'd learned the hard way — through sessions, mistakes, and mentors generous enough to share. I started asking myself: how do I scale that? How do I make sure this knowledge doesn't stay locked inside one room, or one career?

MixAssist is my answer. Everything I know about mixing — my philosophy, my technique, my ear — available to anyone serious enough to use it. Not a course you watch and forget. A real conversation, at 2am, when you actually need it.

"I've spent 25 years learning things that took me years to figure out. I built MixAssist so the next generation doesn't have to wait that long."
