Spotting Counterfeit Music Man Guitars
Music Man counterfeits are uncommon but do exist, particularly for popular models like the John Petrucci Majesty and StingRay bass. Since all genuine EBMM guitars are handcrafted in San Luis Obispo, CA, fakes stand out on closer inspection.
Serial Number & Origin▼
- ▶All genuine Ernie Ball Music Man guitars are made in San Luis Obispo, California. Any EBMM-branded guitar claiming to be made elsewhere is a fake (note: Sterling by Music Man is a separate, import line).
- ▶Verify the serial number prefix (E, G, or B) and year digits match known EBMM patterns.
Hardware & Build Quality▼
- ▶EBMM uses proprietary hardware including their own bridge designs, tuners, and pickups. Generic or third-party hardware on a claimed Music Man is a red flag.
- ▶The 4+2 headstock configuration (on 6-string guitars) is a Music Man signature. Incorrect headstock designs or tuner layouts are a giveaway.
- ▶Music Man's oil-and-wax neck finish has a distinctive smooth, natural feel. A heavily lacquered neck on a claimed EBMM is inconsistent.
Frequently Asked Questions
Where are Music Man guitars made?▼
All Ernie Ball Music Man guitars are made by hand in San Luis Obispo, California. Every instrument in the EBMM line — from the StingRay bass to the John Petrucci Majesty — is built at the same SLO facility by a small team of dedicated craftspeople. The Sterling by Music Man import line is made in Indonesia, Korea, or China and is a separate, lower-priced brand.
What is the difference between Music Man and Sterling?▼
Music Man (full name: Ernie Ball Music Man) is the premium USA-made line, handcrafted in San Luis Obispo, California. Sterling by Music Man is the affordable import line with similar body shapes and headstock designs but made overseas with different materials and hardware. Sterling serials use different prefix codes and should not be confused with EBMM instruments.
Did Leo Fender design Music Man guitars?▼
Yes. After selling Fender to CBS in 1965, Leo Fender was bound by a non-compete agreement. When it expired in the mid-1970s, he joined Music Man as a consultant, working under his company "CLF Research." The StingRay bass (1976) is widely considered his finest bass design. Fender eventually severed ties with Music Man in 1979 and immediately founded G&L Musical Instruments, where he continued designing guitars until his death in 1991.

More About Music Man
Music Man was founded in 1974 in Fullerton, California, by Forrest White and Tom Walker — two former Fender executives who had worked closely with Leo Fender. When Leo Fender sold his company to CBS in 1965, he was bound by a non-compete agreement that prevented him from building guitars for several years. When that agreement expired in 1975, he joined Music Man as a designer, producing instruments that reflected everything he had learned at Fender. The StingRay bass (1976) is widely considered Leo Fender's finest bass design: a high-output, active electronics instrument that remains in production today and has been covered by countless manufacturers.
Ernie Ball, the string manufacturer, purchased Music Man in 1984 after a dispute with the previous ownership. Under Ernie Ball, the company was renamed Ernie Ball Music Man and relocated to San Luis Obispo, California, where it has remained. The new ownership invested in the factory and workforce, improving build consistency and adding the custom finishes and options that made EBMM a premium brand. John Petrucci of Dream Theater began his association with the brand in 1994; his signature JP series models became some of the most technically sophisticated production guitars ever built.
Ernie Ball Music Man remains privately owned by the Ball family and manufactures exclusively in San Luis Obispo. Every instrument in the EBMM line is made in California — the company has resisted the industry trend toward import production for its main line, positioning itself alongside PRS and Gibson as one of the few major brands committed to domestic manufacture. The Sterling by Music Man import line serves the entry-level market without compromising the EBMM brand's USA-made identity.
