Original Fender Pre-CBS Guitar Finishes: The Definitive Authentication Guide
Original Fender Pre-CBS Guitar Finishes: The Definitive Authentication Guide
Why Pre-CBS Fender Finishes Matter
The finish on a vintage Fender guitar tells a story—not just of age and wear, but of authenticity, originality, and ultimately, value. Pre-CBS Fender guitars (manufactured before the 1965 CBS acquisition) represent the pinnacle of Leo Fender's original vision, and their finishes are dramatically different from modern reproductions. Understanding these differences is crucial for anyone owning or considering the purchase of a vintage Fender instrument.
Original pre-CBS finishes command premium prices because they represent:
Authentic nitrocellulose lacquer applied using period-correct techniques
Natural aging patterns that cannot be convincingly replicated
Historical significance as examples of 1950s and early 1960s American manufacturing excellence
Proof of originality that can mean the difference between a $15,000 guitar and a $150,000 guitar
The ability to authenticate an original finish versus a refinish can determine whether you own a valuable collector's piece or simply a good playing instrument. At Edgewater Guitars, we've seen countless examples where finish authenticity made the difference between a modest offer and a life-changing payday.
Historical Context of Pre-CBS Fender Finishes
The Nitrocellulose Era (1951-1965)
Leo Fender chose nitrocellulose lacquer for his instruments because it was the standard automotive finish of the era—durable, workable, and capable of producing brilliant colors. During the pre-CBS period, Fender used specific techniques and materials that create identifiable characteristics:
1951-1954: The Early Years
Thicker nitrocellulose applications
Limited color palette (primarily blonde, sunburst, and black)
Hand-sprayed techniques with visible texture
Desert Sand primer consistently used as undercoat
1955-1959: Color Expansion
Introduction of custom colors in 1956
DuPont automotive paint system adoption
Systematic color coding system implementation
Refined spraying techniques producing smoother finishes
1960-1965: The Golden Era
Peak period for custom color availability
Most sophisticated finish application techniques
Highest quality nitrocellulose formulations
Transitional period leading to CBS changes in late 1965
Why CBS Changed Everything
When CBS acquired Fender in 1965, cost-cutting measures immediately affected finish quality:
Thinner finish applications
Different primer systems
Polyurethane experimentation beginning in the late 1960s
Mass production techniques replacing hand-application methods
Understanding this historical context helps explain why pre-CBS finishes behave differently as they age and why they're so highly valued by collectors today.
Current Market Value Impact of Original Finishes
Detailed Authentication Guide
Visual Identification of Original Nitrocellulose
1. Natural Checking Patterns Original nitrocellulose develops distinctive checking (fine cracks) over time:
Random, organic patterns following wood grain
Deeper penetration into finish layers
Yellowing or amber coloration in crack lines
Graduated density (more checking in high-wear areas)
Warning signs of artificial checking:
Too uniform or geometric patterns
Surface-only cracks that don't penetrate
Lack of natural coloration in crack lines
Sudden appearance in low-wear areas
2. Color Aging Characteristics Pre-CBS finishes age in predictable ways:
Sunburst: Yellow becomes more amber, red fades to orange
Blonde: Develops golden honey coloration
White finishes: Yellow naturally, especially around binding
Black: May fade to dark green or brown in sunlight exposure
Custom colors: Fade according to pigment stability
3. Finish Thickness and Texture Original pre-CBS finishes have distinct tactile qualities:
Thicker application than modern finishes (can measure with paint thickness gauge)
Slight orange peel texture from hand-spraying
Softness that develops with age (nitro becomes more pliable)
Visible brush marks or spray patterns in certain light angles
Scientific Authentication Methods
1. UV Light Examination Under ultraviolet light, original finishes display:
Specific fluorescence patterns unique to vintage nitrocellulose
Different UV response in worn areas versus protected areas
Primer visibility through thin spots
Modern refinishes often fluoresce differently or uniformly
2. Microscopic Analysis Professional authentication may involve:
Finish layer counting (original vs. refinish layers)
Pigment particle analysis
Primer composition verification
Wood grain visibility assessment
3. Paint Thickness Measurement Using electronic paint thickness gauges:
Original finishes: typically 4-8 mils thick
Modern refinishes: often thinner (2-4 mils) or thicker (10+ mils)
Consistent readings across the instrument
Variations that follow natural wear patterns
Cavity and Hardware Inspection
Control Cavity Evidence:
Overspray patterns consistent with original finish application
Masking tape residue or color codes
Desert Sand primer visible in cavities
Natural aging of finish edges
Neck Pocket Authentication:
Finish consistency with body
Proper masking lines
Age-appropriate primer visibility
Matching serial number dates with finish characteristics
Hardware Relationships:
Finish wear patterns around original hardware
Color preservation under long-installed parts
Proper aging patterns around pickup rings and pickguards
Screw hole integrity and finish edges
Common Finish Types and Identification
Standard Finishes
Two-Color Sunburst (1954-1958)
Yellow to brown gradient
Hand-sprayed with visible texture
Natural fading to orange tones
Black edge binding on bodies
Three-Color Sunburst (1958-Present)
Red center band addition
More complex color graduation
Red pigment fading to orange over time
UV-reactive color changes
Blonde/White Blonde
Clear nitrocellulose over ash or alder
Natural wood grain visibility
Golden aging characteristics
Often confused with Olympic White
Custom Colors (1956-1965)
Lake Placid Blue
Metallic blue with silver flake
Fades to green tones over time
Often shows checking patterns
Popular choice for Stratocasters
Fiesta Red
Bright red automotive paint
Fades to orange or pink
Desert Sand primer underneath
Shows dramatic UV fading
Olympic White
Pure white nitrocellulose
Yellows naturally with age
Often mistaken for aged blonde
Popular on all models
Rare Custom Colors
Burgundy Mist: Deep red-brown metallic
Sonic Blue: Light blue, often fades to green
Sherwood Green: Forest green, rare and valuable
Shoreline Gold: Metallic gold, extremely rare
Identifying Refinished Instruments
Common Refinish Warning Signs:
Perfectly uniform color without natural variation
Modern polyurethane "plastic" feel
Lack of appropriate wear patterns
Color combinations not offered in specific years
Artificial aging attempts (fake checking, staining)
Overspray in inappropriate areas
Missing or incorrect primer layers
Hardware mounting evidence inconsistent with finish age
Tonal Impact of Original Finishes
While finish primarily affects value and authenticity, original nitrocellulose also influences tone:
Resonance Characteristics:
Thinner, more flexible finish allows wood to vibrate more freely
Age-related softening of nitrocellulose enhances resonance
Original finish thickness optimized for tonal balance
Chemical composition affects harmonic dampening
Player Reports: Many musicians report that guitars with original finishes feel more "alive" and responsive. While subjective, this perception combined with historical significance makes original finish instruments highly desirable for both playing and collecting.
