Jeff Cotton:
Guitar, Amp, Electronics, String Repair

Jeff got his musical start in the 4th grade – he learned how to play clarinet and continued with it for 8 years. In high school, he played the French horn and also learned how to play the guitar. Moving to California from his native New Hampshire, Jeff attended the Musicians Institute in Hollywood, where he honed his guitar skills. Today he plays acoustic guitar, electric guitar, and mandolin in a couple of local bands. He also works part-time as a sound technician at the Hotel Utah and other local venues.

Jeff has been repairing musical instruments for as long as he can remember, starting with his own guitars. He started working at Bronstein Music in 2005 and is now responsible for string repairs, electronics repairs, and keyboard repairs. To say that Jeff is versatile is understating the point. On any given day, you can find Jeff restringing a guitar or bass, fixing a violin, viola, cello or string bass, or reading a schematic for an electronic musical instrument – and that’s all before lunch!

Ron Graham:
Woodwind and Brass Repair

A native of San Francisco, Ron was raised in Pleasanton where he attended Amador Valley High School. His parents, both pianists, taught him piano at an early age. Be began playing clarinet in 4th grade and added alto saxophone in high school.

Ron matriculated to San Francisco State University where he earned a Bachelor of Music with an emphasis in Saxophone Performance. By his early college years, he had started playing professional music engagements. He led his own jazz quintet “Cornet Pocket” in venues in and around San Francisco. Performances credits include the Monterey Jazz Festival, the San Francisco Opera Orchestra, and tours abroad with Merl Saunders (Grateful Dead) and Don Carlos (Black Uhuru).

It turns out that Ron is a “triple threat” – not only does he play music, but he’s been a music teacher, and is now a musical instrument repair technician. He began to work at Bronstein Music in 1991 as a woodwind teacher, something he did for 15 years. In 2000, Ron began to repair instruments, and by 2005 that had become his full-time job. Today Ron repairs all woodwind and brass instruments.

Ultrasonic Cleaning

Bronstein Music also offers ultrasonic cleaning for brass instruments. This system will easily accommodate trumpets, trombones, baritones, sousaphones and tubas. This system cleans quickly and eliminates the need for strong acids.
