The debate between jazz basses from the 60s and 70s often hinges on the string spacing, with aficionados eagerly discussing the differences and their impacts on playability. This exploration delves into the intricacies of string spacing in jazz basses from these two decades, offering a nuanced comparison that illuminates the unique characteristics of each era's instruments.

Jazz basses produced in the 1960s typically featured narrow string spacing, which offered several advantages to players. The closer proximity of the strings enabled easier string muting and facilitated faster playing, making these basses highly sought after by bebop and hard bop musicians who favoured rapid, complex phrasing.

Jazz Bases from the 60s: Narrow String Spacing
Basses crafted in the 1960s often sported string spacing ranging from 18 to 19mm at the bridge, with some variants offering even narrower spacing. This design allowed players to navigate the fingerboard with exceptional dexterity, enabling them to execute advanced techniques such as tremolo picking, artificial harmonics, and rapid note articulation with relative ease.

Examples of 1960s jazz basses with narrow string spacing include the models produced by Fender during their golden era. These basses, including the Precision Bass (introduced in 1951 but widely adopted in the 1960s) and the Jazz Bass (launched in 1960), featured narrower string spacing compared to their modern counterparts, making them highly revered among vintage bass collectors and discerning players.
The Influence on Playing Style

The narrow string spacing of 1960s jazz basses encouraged a playing style characterized by speed, precision, and articulate single-note lines. Musicians like Jack Casady and Carol Kaye leveraged the close string proximity to develop intricate, biting riffs and melodic phrases that defined the era's jazz and pop standards.
However, the narrow spacing also presented challenges, particularly for players with larger hands or those seeking a broader sonic palette. The close proximity of the strings could make barre chords and certain chord shapes more challenging to fret accurately, and the bridge pickup's tone might lack the full-bodied warmth associated with wider string spacing.
Modern Reissues and Their Significance

Recognizing the enduring appeal of 1960s jazz bass models, contemporary manufacturers have released meticulously crafted reissues that faithfully replicate the narrow string spacing of their vintage counterparts. These instruments, such as the Fender American Professional Jazz Bass and Squier Classic Vibe '60s Jazz Bass, cater to the growing demand for instruments that capture the distinctive tone and playability of the golden era.
By offering modern players the opportunity to experience the sonic and tactile heritage of the 1960s, these reissues serve as vital links to the past, fostering a deeper understanding and appreciation for the role of string spacing in shaping the jazz bass's iconic sound and reputation.
Jazz Bases from the 70s: Evolving Spacing

As the decade progressed, jazz basses began to exhibit wider string spacing, reflecting the musical shifts and changing player preferences. The string spacing on these basses typically ranged from 19 to 20mm at the bridge, offering a balance between the speed-oriented playability of the 1960s models and the broader sonic potential of wider-spaced strings.
One notable example of a 1970s jazz bass with wider string spacing is the Fender Jazz Bass produced during the CBS era (1965-1981). As production techniques and materials evolved, so too did the string spacing, with many of these basses offering a slightly wider bridge spacing than their 1960s counterparts. This increase in string spacing contributed to a fuller, more resonant tone, reflecting the shifting musical landscape of the decade.









The Impact on Tone and Playability
The wider string spacing of 1970s jazz basses allowed for a more expansive tonal palette, with better-defined low-end punch and enhanced mid-range clarity. This tonal evolution suited the broader range of musical styles emerging during the decade, from fusion and funk to rock and disco. Players such as Stanley Clarke and Larry Graham capitalized on the versatility offered by the wider string spacing to develop innovative bass lines that transcended genre boundaries.
While the increased string spacing facilitated a more diverse range of playing styles and tonal possibilities, it also presented challenges. Players accustomed to the narrow string spacing of 1960s basses might find the wider spacing more demanding, requiring adjustment in technique and finger placement to maintain the same level of precision and speed.
The Enduring Legacy of 1970s Jazz Bases
The jazz basses produced in the 1970s continue to influence contemporary bass design and playing techniques. Many modern bassists esteem the wider string spacing of these instruments for its ability to accommodate a broad range of playing styles and musical genres. The enduring popularity of the 1970s jazz bass is evident in the proliferation of reissues and tribute models, such as the Fender Player Jazz Bass and Squier Classic Vibe '70s Jazz Bass, which cater to the demands of today's musicians seeking to connect with the rich heritage of the jazz bass.
The choice between a 1960s or 1970s-inspired jazz bass ultimately depends on the player's personal preferences, playing style, and the specific tonal and sonic objectives of their music. By syntactic diligence and an inclusive understanding of the unique characteristics of jazz basses from these two influential decades, bassists can make informed decisions, honing their craft and expanding their horizons in the process.
