How it started
From a family garage to 10,000 square feet across four neighboring addresses on Oak Street.
Rosen Sound began in Rob’s mother’s garage when he was 16. He bought, repaired and sold Yamaha DX7s, learning to service them himself after enough difficult deals and disappointing experiences with repair shops. Before long, he was taking on repairs for local musicians at $25 an hour.
Early customers came through Craigslist and friends. Word spread quickly through the music community, and Rob began working for keyboardists with the Eagles, Rick Springfield and Billy Idol, as well as studios throughout Los Angeles.
After losing his day job in late 2013, Rob committed to opening a shop. Financed with a few maxed-out credit cards, Rosen Sound opened at 1008 W. Oak Street in early 2014. The original space combined synthesizer, guitar, amplifier and pro audio repair with a recording studio.
The early years were difficult. Careful business decisions and sweat equity kept the doors open while the shop’s reputation grew. Rosen Sound gradually expanded into neighboring spaces, with vintage synthesizers remaining at the center of the business.
The owner
Rob Rosen
Owner & Principal Technician
Born into a Peruvian and Jewish family of jazz and classical upright bassists (how's that for an intro), Rob started out on drums before synthesizers took over in high school. Rush, Van Halen and the keyboard-heavy metal bands of Scandinavia fueled the obsession. He considers himself the world’s biggest Iron Maiden fan.
Repair work began as a necessity: he couldn’t afford to have his own gear serviced. His interest in how instruments produced their sound eventually became a career, though he still plays keyboards and occasionally performs with his metal band.
Today, Rob divides his time between restoration work, circuit design and running the shop with a particular focus on training the next generation of synth techs. Away from the bench, his interests include 3D CAD, smoked barbecue, tennis, vintage wrist watches and collecting synthesizers. He is also a father to two sons and has a dog, Buster.
Outside of Synths
Rob collects and services vintage wristwatches as a hobby and occasionally trades them for synthesizers. He is always looking for a tennis opponent as well. For more about Rob or to discuss old watches, visit robrosen.com.
