About the Engineer

Peter Duff is a recording engineer, music producer, multi-instrumentalist, and songwriter with a passion for music and audio. Peter has a bachelor's degree in music and recording, and has been recording and producing bands and solo artists since 2009. In addition, Peter plays guitar in Hard to Hit, a Pop-Punk band signed to Manic Kat Records.

His musical journey began with the trombone and saxophone in school bands in the Sacramento area where he grew up. After falling in love with electric guitar in middle school and playing in rock bands during high school, he decided to pursue music professionally and moved to Southern California to study at Cal Poly Pomona. In 2014, Peter moved to San Diego where he currently works full time as a recording engineer.

Because of his experience as a performer and his formal music education, Peter understands recording from the perspective of the artist and engineer. He strives for a big sound focusing on clarity, energy, and excitement while staying true to the music and the artist’s sound and vision. Peter values and respects the privilege of being entrusted with presenting other people’s art, and loves to be able to take part in other people’s music.



"I can't recommend Peter and the Grey Brick Recording Studio enough. Peter is a great guy and is a pleasure to work and hang out with. His studio gives him the tools he needs to make your music come to life in ways that you wouldn't have imagined yourself. In the studio, it becomes immediately apparent that Peter takes his work very seriously, while still maintaining a comfortable and fun environment. I can't recommend it enough!"

-Tyler Gill

"I was blown away by the beautiful equipment and Peter's skill.  He seriously knows his stuff and is really able to grasp what the artist wants to convey through their music.  We were on the same page throughout the entire process, because he knows what he is talking about and has the musicians' best interest in mind."

-Eliza Rose Vera

"I'm speechless, these are the rare moments where you meet a person that can bring your vision to a reality, moments like that are unforgettable. Thank you Peter."


"Peter is clearly a not just a sound engineer, but also a musician & a producer. It is evident that he takes passion & pride in his work as he very diligently & professionally works to get the finished product you are looking for. If you want to get your recordings/mixes where you want them to be call Peter @ The grey brick recording studio."

-Nick Lanari

"Peter was able to help take my music to new heights. When we were finished, I couldn't believe what was coming through the speakers. The studio is a great, laid back environment and the expertise of Peter Duff is a force that will drive any music into the direction it needs to go!"
