In mixing my objective is to enhance the sonic character and attitude of each recording. All of the mixing I do is hybrid, combining my Pro Tools HDX rig and plug-ins with my vast array of analog outboard gear. Depending on the sonic demands of the project I may or may not use a summing mixer.


In mastering my objective is to ensure the best possible quality and translatability of every song I work with. Along with the musical sensitivities I focus heavily on the signal chain and gain structure to insure the highest quality result. My extensive experience coupled with high quality analog and digital signal processing helps me make decisions to achieve the highest quality master possible. All of the mastering I do is hybrid, combining my Pro Tools HDX rig and plug-ins with my vast array of analog outboard gear.


My production starts by finding the artist's intent. Working in and out of the studio my objective is to coach and motivate the performer. I work through song selection, arrangement, sonic and tonal character to find the core focus of the band.
