1957 Fender Precision Bass (Sunburst, Anodized Pickguard): When the P-Bass Got Its Defining Shape

The Fender Precision Bass has been in production since 1951, but the version that has dominated popular music for the past sixty-plus years was introduced in 1957. That year, Leo Fender and his team made two changes that transformed the instrument: they reshaped the body into the double-cutaway contoured form familiar today, and they replaced the original single-coil pickup with the split-coil humbucking pickup that became the defining sound of the electric bass.

A 1957 Precision Bass in sunburst finish with the original anodized aluminum pickguard represents this transitional moment. It is simultaneously the birth of the modern P-Bass and an artifact of its specific historical moment, with hardware and construction details that would change again in subsequent years.

The 1957 Transformation

The original 1951-1956 Precision Bass was a slab body design, essentially a rectangular-ish body without contours. It was functional but not particularly comfortable for extended playing. The 1957 revision introduced the contoured body, with beveled edges on the front and back that allow the player's body and right arm to rest more comfortably against the instrument.

Simultaneously, the pickup changed. The original single-coil pickup had a clear, bright tone that worked well in some contexts but was susceptible to interference hum. The new split-coil design splits the pickup into two staggered coil sections, each covering two strings, wound in opposite directions so they cancel hum. This is still the Precision Bass pickup in 2026.

The 1957 is the instrument that professional bass players adopted and that defined bass guitar sound for decades of popular music.

The Anodized Pickguard

The anodized aluminum pickguard is one of the distinctive features of 1957-1958 Precision Basses. Gold anodized aluminum (not plastic) covers the body, giving the guitar a specific metallic shimmer that was fashionable in the mid-1950s and was used on multiple Fender instruments of the period.

By 1959, Fender switched to white or tortoiseshell plastic pickguards. The anodized aluminum pickguard, therefore, is a specific dating indicator: its presence on a P-Bass strongly suggests production in 1957-1958.

Original anodized guards survive in varying condition. The gold anodizing can wear, discolor, or develop a patina over time. A guard that still shows good gold color with minimal wear is desirable. The guard should fit properly against the body contour without warping or lifting.

Physical Specifications

Dating and Serial Numbers

1957 Precision Basses have serial numbers in specific ranges. Fender's serialization during this period is well-documented. Numbers in the range of approximately 016000-025000 or higher cover mid-to-late 1950s production. Consult the standard Fender serial number references (Gruhn's or other comprehensive guides) for specific 1957 ranges.

The neck date is another key identifier. Fender stamped or wrote dates on the end of the neck (visible when the neck is removed from the body). A neck dated in pencil as "3-57" indicates March 1957 production. Neck dates should be consistent with the body serial number date.

Condition Grades and Values

| Condition | Description | Market Range | |---|---| | Excellent | Original finish 90%+, original pickguard, all hardware, plays well | $25,000 - $55,000 | | Very Good | Original finish 75%+, original or period-correct hardware | $15,000 - $28,000 | | Good | Original finish with wear, some replaced hardware, structurally sound | $9,000 - $16,000 | | Fair | Refinished or significant modifications | $5,000 - $10,000 |

All-original examples in excellent condition with original anodized pickguard command the highest premiums. Any modification (replaced tuners, replaced pickups, blocked truss rod adjustment hole in the headstock) reduces value but does not diminish the instrument's playability.

Authentication Concerns

Neck date: Always verify. Pull the neck and check the pencil or stamp date on the heel.

Pickup: The split-coil pickup is correct for 1957. An original 1951-1956 single-coil would indicate an earlier instrument. A later replacement pickup is a modification that should be disclosed.

Body wood: Authentic 1957 P-Basses are primarily alder. Some very early 1957 production may be ash (Fender was transitioning woods). Ash vs. alder is distinguishable by grain pattern and weight.

Potentiometer codes: The volume and tone pots should have date codes consistent with late 1957 production. Pot codes are printed on the back of the potentiometer housing and follow a standard format indicating year and week of manufacture.

Playing a 1957 P-Bass

The 1957 P-Bass is a working instrument, not just a museum piece. The split-coil pickup has a characteristically warm, round, solid fundamental with gentle high-frequency rolloff. It sits in a mix without effort, sitting in the bass slot without fighting other instruments.

The maple neck on one-piece construction has a slightly different feel than later maple-cap necks, typically described as slightly stiffer and more precise. The 34" scale and approximately 1.75" nut width are modern-standard for P-Bass dimensions.

For a working bassist who wants to play history and owns a proper amplifier and a good set of flatwound strings, a well-set-up 1957 P-Bass is entirely functional and genuinely inspiring.
