Ben Cotta

Owner – Jersey Shore Guitar

Benjamin Cotta is the owner of Jersey Shore Guitar and Instrument Repair. When Benjamin was in grammar school he was sitting on a friends couch while his friend was playing the bass, after feeling the vibrations of the instrument he knew his life would never be the same. Benjamin learned how to play the bass and has played in bands such as lemon juice, devil’s holiday and many other side projects. He current plays the bass in a band called Changing Lanes which travels through the tri-state area to perform.

Benjamin attended the Eastern School of Fretted Instrument Repair and then worked at Guitar Center as a Guitar Tech for two and a half years. He also worked at his former school for about a year while he saved up for his business.

Benjamin shows great attention to detail and treats every instrument as if it were his own. He doesn’t believe in just throwing instruments away or selling them, he takes them apart piece by piece and then repairs them to make them look, sound and feel better than they ever did before. Benjamin likes the challenge of cracks, neck repairs and electronics because he understands the instrument is a extension of the customer and is not something that is easily replaceable.

Benjamin opened up Jersey Shore Guitar Repair (a franchise of Repair Guitar) in November 2016 in Toms River, NJ.

Bob Longo

Owner – Guitar Repair Services

Guitar Repair Services was formed in 2014 after 40 years  of inspiration for the guitar. I couldn’t possibly begin to describe that kind of journey without first thanking my father for seeing some sort of talent in me when I was eight years old. Thanks dad R.I.P.. Beginning in the late seventies and through the eighties of some of the most unbelievable musicians of our time, my interest grew as a kid when I saw Eddie Van Halen’s first Frankenstrat. I then realized you could build your own guitars to your liking. You didn’t have to settle for run of the mill store bought guitars. After years of building my own guitars I decided to get officially schooled in fretted instrument repair. I chose The Eastern School of Fretted Instrument Repair In Freehold N.J. under the direction of Joseph Civitano and Kyle Roggendorff. Today we are together servicing Ocean county, Middlesex county, Union county , Essex county and the tri state area. Our three locations in Freehold, Toms River, and Scotch Plains New Jersey are full service facilities catering to all aspects of fretted instrument repair. My new shop recently opened in March of 2017 in the downtown area of Scotch Plains N.J. just 2 blocks from Route 22. My  objective is simple. Provide quality craftsmanship, in a timely manner,with attention to each players needs. We do the repairs others won’t. Hope to see you not only as a customer but as a fellow musician.

Bobby Longo.
