Most readers of this are probably already aware that Fender USA guitar serial numbers "theoretically" follow a pattern.They were designed to help identify the approximate manufacturing date of the guitar.For example: a guitar whose serial number begins with the letter and number "E8", would have "theoretically" been manufactured in 1988 (E = in the Eighties, 8 = the 8th year...Its appearance is similar to the Jaguar, though it is tonally and physically different in many technical ways.The contoured "offset-waist" body was designed for comfort while playing the guitar in a seated position, as many jazz and blues artists prefer to do.The early series are the most popular for collectors.Also, some The Japanese serial number can be confusing too.A full 25½" scale length, lead and rhythm circuit switching with independent volume and tone controls, and a floating tremolo with tremolo lock, were other keys to the Jazzmaster's character.The tremolo lock can be manually activated to keep the entire guitar from going out of tune if one string breaks. The bridge and tremolo construction is very different from that of the Stratocaster and gives the Jazzmaster a different resonance and generally less sustain.The body is larger than that of other Fender guitars, requiring a more spacious guitar case.The Jazzmaster had unique wide, white "soapbar" pickups that were unlike any other single coil.
