Dating Fender Jazz Bass pickups can be a complex process, as the company has produced numerous variations over the years. However, by examining the pickup's design, materials, and other distinctive features, it is possible to narrow down the production period. The Fender Jazz Bass, introduced in 1960, has undergone significant changes in its pickup design, making it essential to understand these variations to accurately date the pickups.
Early Years (1960-1965)
The early Jazz Bass pickups, produced from 1960 to 1965, were characterized by their unique design, featuring a pair of single-coil pickups with a distinct “thumb rest” shape. These pickups were wound with a heavier gauge wire, typically 42 AWG, and had a DC resistance of around 7.5 kΩ. The bobbin material used during this period was often a gray or black plastic, which can help identify the age of the pickup. Additionally, the pole pieces were typically made of a nickel-silver alloy, and the magnets were Alnico 5.
Transition Period (1965-1970)
During the mid-1960s, Fender began to transition to a new pickup design, featuring a more compact, beveled edge bobbin. This design change was gradual, and pickups from this period may exhibit characteristics from both the early and later designs. The wire gauge used during this period remained relatively consistent, but the DC resistance began to decrease, typically ranging from 6.5 kΩ to 7.5 kΩ. The pole pieces and magnets used during this period remained similar to those used in the early years.
| Year | Pickup Design | Wire Gauge | DC Resistance |
|---|---|---|---|
| 1960-1965 | Single-coil, thumb rest | 42 AWG | 7.5 kΩ |
| 1965-1970 | Compact, beveled edge | 42 AWG | 6.5-7.5 kΩ |
| 1970-1980 | Single-coil, flat bobbin | 43 AWG | 6.0-7.0 kΩ |
Modern Era (1980-Present)
In the 1980s, Fender introduced the American Standard Jazz Bass, which featured a new pickup design with a flat, rectangular bobbin. These pickups were wound with a lighter gauge wire, typically 43 AWG, and had a DC resistance of around 6.0 kΩ. The pole pieces and magnets used during this period were often made of a nickel-plated steel and Alnico 5, respectively. Modern Fender Jazz Bass pickups continue to evolve, with various designs and materials being used, including noise-canceling configurations and alternative magnet materials.
Key Points
- Early Jazz Bass pickups (1960-1965) feature a unique thumb rest design and heavier gauge wire.
- Transition period pickups (1965-1970) exhibit characteristics from both early and later designs.
- Modern pickups (1980-present) feature a flat, rectangular bobbin and lighter gauge wire.
- Pole pieces and magnets used have varied over the years, with nickel-silver, nickel-plated steel, and Alnico 5 being common materials.
- A holistic approach, considering the entire instrument, is essential for accurately dating Fender Jazz Bass pickups.
In conclusion, dating Fender Jazz Bass pickups requires a thorough understanding of the company's design evolution and materials used over the years. By examining the pickup's design, wire gauge, DC resistance, and other distinctive features, it is possible to narrow down the production period and accurately date the pickups. Whether you're a seasoned collector, a working musician, or simply a enthusiast, understanding the history and development of Fender Jazz Bass pickups can provide a deeper appreciation for these iconic instruments.
What are the key differences between early and modern Fender Jazz Bass pickups?
