1966 Fender Mustang: The Student Guitar That Became a Professional Classic
1966 Fender Mustang: The Student Guitar That Became a Professional Classic
Why the 1966 Mustang Matters
The 1966 Fender Mustang represents a fascinating chapter in electric guitar history—a time when Fender's "student" guitar was actually the most popular electric guitar in the world. This was the most popular electric guitar in the world in 1966, with more sold than any other competitive instrument. Built during the peak of American manufacturing excellence and just two years after the model's 1964 debut, the 1966 Mustang embodies the sophisticated engineering and quality craftsmanship that characterized Fender's Fullerton, California factory during this golden era.
What makes the 1966 Mustang historically significant is its unique position as both an accessible instrument for beginners and a sophisticated design that attracted professional players. Unlike typical "student" guitars that compromised on features, the Mustang offered genuine innovations including Fender's new Dynamic Vibrato system, unique switching options, and the comfortable 24-inch scale length that would later influence countless alternative and indie rock musicians.
Key characteristics that define the 1966 Mustang:
Peak production year with over 16,000 units shipped worldwide
Pre-CBS quality construction with premium materials and hand-built attention to detail
Introduction of innovative features like the Dynamic Vibrato tailpiece and floating bridge system
Unique pickup switching that offered phase options unavailable on professional models
Built during Fender's manufacturing peak before the transition complexities of the CBS era
Historical Context: Fender at Its Peak
During 1966, the Fender Musical Instruments Corporation was operating at unprecedented production levels while maintaining the quality standards established by Leo Fender. Fender production was at its absolute height at the time and over 16,000 Mustangs alone were shipped out in that single 12-month period. This was the year before CBS ownership would begin to influence manufacturing decisions, making 1966 instruments particularly desirable among collectors who value pre-corporate influence craftsmanship.
The Mustang was part of Fender's strategic redesign of their student instrument line, which also included updates to the Duo-Sonic and Musicmaster models. Introduced just before the CBS takeover of Fender, the Mustang was part of a redesign of Fender's line of student level guitars which included the Duo-sonic and Musicmaster. However, calling the Mustang merely a "student" guitar understates its sophisticated design and broad appeal.
Notable artists using Mustangs during this period:
David Byrne with early Talking Heads recordings
Various session musicians attracted to the instrument's unique tonal possibilities
Garage bands across America who appreciated the affordable price and professional features
The model's immediate success demonstrated that musicians wanted accessible instruments without sacrificing quality or innovation. Moderately priced at $189.50, the original Mustang was a dual-pickup, 22-fret, medium-scale guitar that owed much to the Duo-Sonic, although it had an offset waist like a Jazzmaster.
Detailed Identification Guide
Authenticating a genuine 1966 Fender Mustang requires examining multiple identifying characteristics. Serial numbers alone cannot definitively date these instruments due to Fender's production methods during this period.
Serial Number Ranges
110000 - 200000: 1966 However, Fender neck plates were selected from large bins and it's difficult to properly date these guitars by neck plate alone. Serial numbers for 1966 typically fall between 110,000 and 180,000, stamped on the four-bolt neck plate.
Neck Dating
The most reliable identifier is the neck date, typically found stamped or handwritten on the neck heel. Neck stamp "16JAN66B" (Mustang model, January, 1966, B neck width = 1 5/8") The format usually appears as month-day-year, such as "5FEB66B" or "23JUN66A."
Neck width codes:
A width: 1½" nut width (rare student option)
B width: 1⅝" nut width (standard)
Potentiometer Codes
1966 Mustangs used CTS potentiometers with date codes that can verify production timing. The pots are dated to the 17th week of 1966 The format shows manufacturer code (137 for CTS), followed by the last two digits of the year and week number.

Tonal Characteristics
The 1966 Mustang offers a distinctive sonic signature that combines Fender's classic single-coil clarity with the unique characteristics of its shorter scale length and pickup positioning. The 24-inch scale creates slightly less string tension than standard Fender guitars, resulting in a more relaxed feel and subtly different harmonic content.
Sound Profile:
Clean tones: Bright and articulate with excellent note definition, typical Fender chime but with slightly warmer midrange due to shorter scale
Bridge pickup: Cutting, trebly character perfect for rhythm work and lead lines
Neck pickup: Warmer and rounder than typical Fender neck positions, with musical low-mid presence
Both pickups engaged: Complex harmonic interactions, especially when using the phase switching options
Unique Switching Characteristics: Each pickup had its own adjacent three-position slider switch (in phase on—off—out of phase on), yielding eight different tone settings. This innovative system provided tonal variety unavailable on Stratocasters or Telecasters of the era:
Both pickups off (silence)
Neck pickup only (in phase)
Bridge pickup only (in phase)
Both pickups in phase (traditional two-pickup sound)
Neck pickup out of phase, bridge off
Bridge pickup out of phase, neck off
Both pickups out of phase (thin, nasal tone)
Neck in phase, bridge out of phase (hollow, complex interaction)
The out-of-phase combinations create unique tonal colors particularly useful for recording and creating distinctive textures. Many professional players discovered these options offered sounds unavailable from more expensive Fender models.
Common Issues & Modifications
When evaluating a 1966 Mustang, understanding typical wear patterns and common modifications helps determine originality and fair market value.
Typical Condition Issues
Finish Wear:
Checking (fine hairline cracks) in nitrocellulose finish is normal and adds to vintage character
Edge wear around the body, particularly on the upper bout and back edges
Belt buckle wear on the back is common and acceptable
Color fading varies by original finish—blues tend to fade more than reds
Hardware Problems:
Dynamic Vibrato systems sometimes suffer from spring fatigue or worn pivot points
Tuning gear replacement is common—original "F" style tuners are frequently upgraded
Bridge saddle wear from decades of string contact
Potentiometer crackling or complete failure
Electronics:
Original pickups sometimes lose output or develop microphonic feedback
Wiring harnesses may show aging or amateur modification attempts
Pickup selector switches can become intermittent
Common Modifications
Pickup Upgrades: Many players replaced the original pickups with higher-output alternatives, particularly humbuckers in the bridge position (following Kurt Cobain's example). While this improves playability for some styles, it significantly reduces collector value.
Hardware Changes:
Locking tuners installation (usually requiring new holes)
Bridge modifications or complete tremolo system replacement
Strap lock installation
Refinishing: Unfortunately, many Mustangs were refinished during their "cheap vintage guitar" period in the 1980s and 1990s. Once it's refinished...not much. A few hundred bucks. Refinished examples, even professional jobs, typically sell for 60-70% less than original finish guitars.
Warning Signs of Issues
Non-Original Parts:
Modern pickup rings or covers that don't match vintage specifications
Replacement neck plates without proper serial numbers
Non-period-correct wiring or capacitors
Modern bridge saddles or tremolo springs
Structural Problems:
Neck pocket looseness or improper fit
Headstock repairs (less common on Mustangs than other models)
Body cracks or significant impact damage
Neck bow or twist that affects playability
Why Players and Collectors Value 1966 Mustangs
The 1966 Mustang occupies a unique position in guitar history as an instrument that transcends its original "student guitar" classification to become a genuine professional tool and collector's item.
Playing Characteristics
Comfort and Playability: The 24-inch scale length makes the Mustang exceptionally comfortable for players with smaller hands or those who prefer reduced string tension. The neck was the standard bolt-on Fender configuration of one-piece maple with a rosewood fingerboard and generally feels superbly comfortable in the hand.
Versatility: The unique switching system provides more tonal options than instruments costing several times more. Its individual on/off/on (invert phase) pickup switches allowed for cool tonal variation not officially offered in any of the professional level guitars like the Stratocaster, Telecaster, Jazzmaster, or Jaguar.
Collector Appeal
Historical Significance: 1966 represents peak production quality before corporate ownership changes affected manufacturing approaches. These instruments demonstrate Fender's ability to create innovative, high-quality guitars at accessible price points.
Cultural Impact: The Mustang's association with alternative rock, particularly grunge music, has created lasting interest across generations. As one of the more affordable "genuine vintage Fender guitars" in the '80s and '90s, Mustangs were snapped up and hot-rodded by punk, grunge, indie-rock and alt-rock players
Investment Potential: Unlike many guitars that peak in value and plateau, vintage Mustangs continue appreciating as musicians discover their quality and unique characteristics. The limited production compared to Stratocasters and Telecasters creates natural scarcity that supports long-term value growth.
Professional Applications
Modern recording artists value vintage Mustangs for their distinctive character and recording-friendly tonal options. The shorter scale provides different string feel and harmonic content that cuts through dense mixes differently than standard-scale guitars.
