How to Date Your Gibson ES-330: Complete Vintage Authentication Guide
How to Date Your Gibson ES-330: Complete Vintage Authentication Guide
Why Dating Your Gibson ES-330 Matters
Learning how to date a Gibson ES-330 accurately is essential for authentication, proper valuation, insurance documentation, and understanding your instrument's place in electric guitar history. The Gibson ES-330 represents a unique and often underappreciated guitar—a fully hollow body with a sharp, cutting tone that influenced countless blues, rock, and jazz players.
Whether you own a vintage ES-330 from the coveted 1960s era or a later model, determining its exact manufacturing year affects everything from market value to restoration approaches. Certain years and specifications command premium prices, particularly early examples with P-90 pickups, specific finish options, and original hardware. The ES-330's association with legendary players like B.B. King, Grant Green, and Alvin Lee has elevated collector interest significantly.
This comprehensive guide teaches you how to date your Gibson ES-330 using multiple authentication methods, ensuring accuracy regardless of which era your instrument represents.
Understanding the Gibson ES-330 History
Before diving into dating methods, understanding the ES-330's evolution provides crucial context:
The Birth of the ES-330 (1959)
Gibson introduced the ES-330T (Thinline) in 1959 as a fully hollow alternative to the semi-hollow ES-335:
Original Design:
Fully hollow body (no center block)
Thinline profile (1 5/8" depth)
Double cutaway design
P-90 pickups (not humbuckers)
Laminated maple construction
16" lower bout width
Key Distinction: Unlike the ES-335 with its solid center block, the ES-330 was completely hollow, creating different tonal characteristics—brighter, more acoustic-like tone with increased feedback potential at high volumes.
Target Market: Players wanting a more affordable thinline guitar with traditional single-coil tone, or those specifically seeking the hollow body character without the semi-hollow design.
Major ES-330 Evolution Periods

1963-1968: "Block Neck" Era
Block inlays replace dots (1962-1963 transition)
P-90 pickups continue
Pointed cutaways (1963-1968)
Short pickguard
1969-1972: Return to Rounded Cutaways
Mickey Mouse ears return
P-90 pickups continue
Various specification changes
1970s-1990s: Various Production Periods
Discontinued and reintroduced multiple times

How to Date Your Gibson ES-330: Serial Number Systems
Understanding Gibson's serial number systems is the foundation for dating your ES-330. However, serial numbers alone cannot definitively date these guitars—always use multiple verification methods.
Important Resource: For quick serial number reference, use our Gibson Serial Number Lookup Tool to find your guitar's approximate year based on serial number ranges.
1959-1960: Ink-Stamped Serial Numbers
Early ES-330 guitars used Gibson's ink-stamped serial number system:
Location: Inside guitar (visible through f-holes)
Stamped on internal bracing or top
May require good lighting and angle
Sometimes difficult to see
Format: 5-6 digits
Approximate Serial Number Ranges:
1959: 9xxxx - 0xxxx range (numbering restarted during year)
1960: 0xxxx - 1xxxx range
Critical Notes:
Significant overlap between years
Inconsistent numbering
Serial numbers alone insufficient
Factory Order Numbers more reliable
How to Find Your Serial Number:
Look through treble-side f-hole
Use flashlight for illumination
Serial number stamped inside guitar
May need to adjust viewing angle
Can be partially obscured by braces
Record complete number
Pro Tip: Use our Gibson Serial Number Lookup Tool for instant reference once you've found your serial number.
1961-1970: Impressed Serial Numbers
Gibson transitioned to impressed serial numbers on the back of the headstock:
Location: Back of headstock (stamped into wood)
Format: 5-6 digits
Approximate Ranges:
1961: 1xxxx - 2xxxx range (some with A prefix)
1962: 2xxxx - 3xxxx range
1963: 3xxxx - 4xxxx range
1964: 4xxxx - 7xxxx range
1965: 7xxxx - 9xxxx range
1966: 0xxxx - 1xxxx range (numbering restarted)
1967: 1xxxx - 8xxxx range
1968: 8xxxx - 0xxxx range (restarted again)
1969: 0xxxx - 9xxxx range
1970: 0xxxxx range (six digits)
Critical Challenge: Extensive overlap and duplication
Same serial numbers appear across multiple years
Extremely unreliable for precise dating
Must use Factory Order Numbers for accuracy
1970-1975: Six-Digit Serial Numbers
Format: Six digits
First digit indicates year (0=1970, 1=1971, etc.)
More reliable than 1960s system
"MADE IN USA" stamp appears
1977-Present: Modern Serial Number Systems
1977-2013: Eight-digit formats with letter prefixes
More consistent than earlier systems
2014-Present: YYMMXXXX format
First two digits = year
Second two digits = month
Most reliable system
Factory Order Numbers (FON): The Most Reliable Vintage ES-330 Dating Method
For vintage ES-330 guitars, Factory Order Numbers provide the most accurate dating:
What FON Tells You: Production batch and year of manufacture
Location: Inside guitar
Visible through f-holes
Stamped on bracing, top, or label
Orange label (1959-1961) or white label (1962+)
Format: Letter followed by 3-4 digits
Letter indicates year
Numbers indicate production batch
FON Letter Codes for Vintage ES-330 Era (1959-1970):
S = 1959
R = 1960
Q = 1961
P = 1962
O = 1963
N = 1964
M = 1965
L = 1966
K = 1967
J = 1968
I = 1969
Example: FON "P 2847" = 1962 production, batch 2847
How to Find FON:
Look through f-holes (both sides)
Check orange or white label inside
FON may be stamped on bracing
Use flashlight and mirror
May require string removal for better visibility
Photograph for documentation
Why FON Is Critical for ES-330:

Methods:
Remove pickguard (provides some access)
Look through f-holes with flashlight and dental mirror
Some pots visible, some obscured
May require professional access for complete inspection
Record codes from accessible pots
Single Pickup ES-330T:
Two pots (volume and tone)
Easier access than two-pickup model
Double Pickup ES-330TD:
Four pots (two volume, two tone)
More difficult to access all pots
Example Codes:
137 6128 = CTS pot, 1961, 28th week
134 6415 = Centralab pot, 1964, 15th week
Interpreting Pot Dates for ES-330
Dating Rules:
Pots date component manufacture

Frequently Asked Questions
How is the ES-330 different from the ES-335?
The ES-330 is fully hollow (no center block) with P-90 single-coil pickups, while the ES-335 has a solid center block with humbucker pickups. ES-330 is lighter, more acoustic-sounding, and more prone to feedback. Use our Gibson Serial Number Lookup Tool to check your model.
What's more valuable: ES-330T or ES-330TD?
Generally, the ES-330TD (two pickups) is more valuable than the ES-330T (single pickup) due to greater versatility. However, dot neck examples of both are highly collectible.
Are dot neck ES-330s more valuable than block neck?
Yes, dot neck ES-330s (1959-early 1962) are more valuable than block neck models (1962+), similar to other Gibson semi-hollow and hollow models. Dot neck examples with original features command strong premiums.
Did ES-330s ever have humbuckers?
No, factory ES-330s always had P-90 single-coil pickups. Any ES-330 with humbuckers has been modified, which significantly reduces collector value.
Are Mickey Mouse ear cutaways more valuable than pointed?
Generally yes. Mickey Mouse ears (1959-1962, 1969-1972) are preferred, especially on dot neck models. Pointed cutaways (1963-1968) are less desirable to collectors.
What's the difference between long and short pickguards on ES-330TD?
Long pickguards (1959-1962) extend below the bridge pickup. Short pickguards (1962+) end above the bridge pickup. Long pickguards indicate earlier, more valuable production period.
Can I date my ES-330 just by serial number?
Not reliably for 1960s models. Use our Gibson Serial Number Lookup Tool as starting point, then verify with FON, pot codes, inlays, and cutaway style.
Why are ES-330s less expensive than ES-335s?
ES-330s were historically less expensive due to P-90 pickups (vs. humbuckers) and fully hollow construction. However, vintage ES-330 values have risen significantly as players and collectors recognize their unique tone and artist associations.
