Welcome to the only Mastering House in Northern California that cuts Lacquer Masters for Vinyl!


Located next door┬áto the former and famed┬áFantasy Studios in Berkeley, California, George Horn’s mastering studio has been active for the last 30 years. Realizing that the Studios needed a dedicated room for┬áMastering, a room was designed by Tom Hidley in the late 70’s strictly for this purpose. ┬áSince then, countless records from a wide variety of genres┬áhave been┬ámastered here.

Since 2008, George has been operating independently. In early 2014, Anne-Marie Suenram joined the studio as a fellow mastering engineer and in 2018 Katia Dotto joined the team.

Combining both vintage analog and modern digital technology, our studio is equipped to give the finishing touches to any audio project that you may have: whether it is for vinyl, CD/DDP, digital download or interactive media.
