How to Date Vintage Fender and Gibson Guitars Using Potentiometer Codes

If you're trying to determine the age of your vintage Fender or Gibson guitar, potentiometer codes are one of your most reliable dating tools. While serial numbers can be confusing, duplicated, or even missing, the date codes stamped on your guitar's potentiometers (pots) provide concrete evidence of when your instrument was manufactured.

Whether you're a collector researching a potential purchase or an owner considering selling your vintage guitar, understanding how to read pot codes is essential for accurate dating and valuation. At Edgewater Guitars, we've authenticated thousands of vintage guitars throughout Ohio and the Midwest, and pot code verification is always a critical part of our evaluation process.

What Are Potentiometer Date Codes?

Potentiometers—commonly called "pots"—are the variable resistors underneath your guitar's volume and tone knobs. These components control the electrical signal from your pickups, allowing you to adjust volume and tone.

Most vintage guitar pots have date codes stamped directly onto the component casing. These codes indicate when the manufacturer produced that specific potentiometer, providing a reliable timeline for dating your instrument.

Where to Find Pot Codes:

• Remove the control cavity cover plate (back of guitar or pickguard)

• Locate the cylindrical potentiometers attached to the control knobs

• Look for a 6-7 digit number stamped on the metal casing

• You may need to gently rotate the pot to see the full code

• Use a flashlight for better visibility in dark cavities

Important Principle: The pot date represents when the component was manufactured, not necessarily when the guitar was assembled. Guitars were typically assembled within weeks or months after the pots were made, though components sometimes sat in inventory longer.

Understanding the Pot Code Format

Most potentiometer date codes follow the Electronic Industries Alliance (EIA) source-date code format:

Standard Format: XXXYYYZZ or XXXYZ

• XXX = Manufacturer identification code (3 digits)

• YY or Y = Year of manufacture (last 1-2 digits of year)

• ZZ or Z = Week of manufacture (1-52)

Example Breakdown

Code: 1376428

• 137 = CTS (Chicago Telephone Supply) manufacturer

• 64 = Year 1964

• 28 = 28th week of 1964 (approximately July)

Code: 1372152

• 137 = CTS manufacturer

• 21 = Year 1921 or 2021? (See "Year Ambiguity" section below)

• 52 = 52nd week (late December)

Major Potentiometer Manufacturers

Understanding which manufacturers supplied which guitar companies helps verify authenticity:

CTS (Chicago Telephone Supply) - Code: 137

Primary User: Fender guitars and basses Years Used: 1950s through present (for Fender) Characteristics:

• Most common on Telecasters (all years)

• Found on Stratocasters (though less common than Stackpole)

• Standard on Fender basses (Precision and Jazz)

• Often bronze/brass colored casing

• Typically 250K ohm (Fender guitars) or 500K ohm (some models)

Authentication Note: CTS pots on Fenders are completely correct and original. Some collectors mistakenly believe only Stackpole pots are "right" for vintage Fenders, but CTS was extensively used.

Stackpole - Code: 304

Primary User: Fender guitars (especially Stratocasters) Years Used: Mid-1950s through 1960s Characteristics:

• Most associated with vintage Stratocasters

• Common on pre-CBS Fenders (1954-1965)

• Gray or silver-colored casing

• Considered slightly more desirable by collectors (though functionally equivalent)

• 250K ohm standard resistance

Collector Appeal: Stackpole pots on pre-CBS Fenders are highly sought after and command premium prices when all-original.

Centralab - Code: 134

Primary User: Gibson guitars Years Used: 1940s through 1960s Characteristics:

• Predominant manufacturer for Gibson during the "golden era"

• Found on Les Pauls, SGs, ES-335s, and other Gibsons

• Dark gray or black casing

• 500K ohm standard (Gibson used higher resistance than Fender)

• Often installed in plastic "cup" housings

Critical for Dating: Centralab pots are essential for authenticating valuable vintage Gibsons like 1950s Les Pauls.

Other Manufacturers

IRC (International Resistance Company) - Code: 615

• Used occasionally by both Fender and Gibson

• More common in 1970s and later

Clarostat - Code: 137 (different from CTS despite same code)

• Less common, primarily 1940s-1950s

• Requires additional context to differentiate from CTS

Allen Bradley - Various codes

• Higher-end pots used on premium models

• Less common on production instruments

Year Ambiguity: The Century Problem

One challenge with pot codes is determining which century applies:

The Issue

A pot stamped "1375223" shows:

• Manufacturer: CTS (137)

• Year: 52

• Week: 23

But is this 1952 or 2052?

How to Resolve Year Ambiguity

Use Context Clues:

1. Other Guitar Features

   • What style pickups does the guitar have?

   • What type of tuners are installed?

   • What's the neck profile and headstock shape?

   • What finish style is used?

2. Multiple Pot Dating

   • Most guitars have 2-4 pots

   • All should have similar date codes

   • If one pot reads "52" and others read "64," the "52" pot is likely a replacement

3. Serial Numbers and Neck Dates

   • Cross-reference with other dating methods

   • Serial numbers can provide century context

   • Neck date stamps (Fender) confirm the year

4. Visual Age Assessment

   • Genuine 70-year-old components show appropriate aging

   • Wire insulation degradation, solder joint oxidation

   • Natural patina and corrosion patterns

Common Sense Application

If the guitar appears to be:

• A 1950s-style Fender or Gibson → "52" means 1952

• A modern reissue → "52" could mean 2052 (though unlikely as we're only in 2025)

• A 1970s guitar → "72" means 1972

Pro Tip: Very few situations create genuine ambiguity. Visual assessment combined with pot date context makes the correct century obvious in 95% of cases.

Dating Vintage Fender Guitars with Pot Codes

Pre-CBS Fender Era (1950-1965)

Pre-CBS Fenders represent the most collectible American guitars, and pot codes are essential for authentication:

Expected Manufacturers:

• Stackpole (304): Most common on Stratocasters

• CTS (137): Most common on Telecasters and basses

• Occasional others: IRC, Clarostat (less common)

Typical Date Correlation:

Authentication Example: 1959 Fender Stratocaster

What You Should Find:

• 3 pots total (1 volume, 2 tone)

• Stackpole (304) or CTS (137) manufacturer codes

• Date codes reading "59" with various week numbers

• All pots should be within the same year or 1-2 months apart

Red Flags:

• Pots dated 1962 in a supposedly all-original 1959 guitar

• Mix of drastically different date codes (1959, 1967, 1983)

• Wrong manufacturer (modern Asian pots in vintage guitar)

• Pots dated after the guitar's neck date or serial number

CBS Era Fender (1965-1981)

Changes After CBS Acquisition:

• Quality control became less consistent

• Some cost-cutting in component selection

• Pot manufacturers remained largely the same initially

• By the 1970s, more variation in pot manufacturers

Dating Considerations:

• Early CBS (1965-1969) still used Stackpole and CTS extensively

• Later CBS (1970-1981) saw more variety in manufacturers

• Pot codes remain reliable for dating throughout this period

Reading Fender Pot Codes: Step-by-Step

Example Guitar: Vintage Fender Stratocaster

Step 1: Access the Pots

• Remove the pickguard screws (Strat: 11 screws typically)

• Carefully lift the pickguard to expose the control cavity

• Identify the three pots (one volume, two tone)

Step 2: Locate the Codes

• Find the stamped numbers on each pot's metal casing

• Use a flashlight and possibly rotate the pot slightly

• Photograph the codes for reference

Step 3: Decode Each Pot

Pot 1: 3046127

• 304 = Stackpole manufacturer

• 61 = Year 1961

• 27 = 27th week of 1961 (early July)

Pot 2: 3046130

• 304 = Stackpole manufacturer

• 61 = Year 1961

• 30 = 30th week of 1961 (late July)

Pot 3: 3046133

• 304 = Stackpole manufacturer

• 61 = Year 1961

• 33 = 33rd week of 1961 (mid-August)

Conclusion: This guitar was likely assembled in late 1961 or early 1962, using pots manufactured across summer 1961.

Step 4: Cross-Reference

• Check the neck date stamp (should read "1961" or early "1962")

• Verify the serial number falls in the 1961-1962 range (60000-80000)

• Confirm other features match 1961-1962 specifications

Dating Vintage Gibson Guitars with Pot Codes

Golden Era Gibson Dating (1952-1965)

Gibson's golden era—especially the 1958-1960 Les Paul "Burst" years—makes pot code authentication critical for six-figure instruments.

Expected Manufacturer:

• Centralab (134): Overwhelmingly dominant during this period

• Occasionally IRC or other manufacturers

• 500K ohm resistance standard for Gibson

Critical Models and Date Ranges

1958-1960 Les Paul Standard "Bursts"

These guitars command $250,000-$750,000+ depending on condition, making authentication essential:

Expected Pot Codes:

• 1958 Les Paul: Centralab pots dated late 1957 through 1958

• 1959 Les Paul: Centralab pots dated 1958 or 1959

• 1960 Les Paul: Centralab pots dated 1959 or 1960

Example: Authenticating a 1959 Les Paul

What You Should Find:

• 4 pots total (2 volume, 2 tone)

• All Centralab (134) manufacturer codes

• Date codes reading "58" or "59"

• Pots typically within a few weeks/months of each other

Authentic 1959 Pot Code Examples:

• 1345825 (Centralab, 1958, week 25)

• 1345847 (Centralab, 1958, week 47)

• 1345901 (Centralab, 1959, week 01)

• 1345923 (Centralab, 1959, week 23)

Why This Matters: A genuine 1959 Les Paul with all original Centralab pots dated 1958-1959 might be worth $400,000+. The same guitar with 1970s replacement pots might drop to $200,000-250,000—a $150,000+ difference based on pot codes alone.

Other Valuable Gibson Models

1961-1964 Gibson SG Standard

Expected Pot Codes:

• Centralab (134) manufacturer

• Years 1961-1964 depending on model year

• Should correlate with other dating features (serial number, pickup types)

1958-1964 Gibson ES-335

Expected Pot Codes:

• Centralab (134) primary manufacturer

• Should align with "dot" vs "block" inlay periods

• PAF pickups (1958-1962) should correlate with appropriate pot dates

1952-1960 Les Paul Goldtop

Expected Pot Codes:

• Centralab (134) throughout production

• P-90 era (1952-1956): Centralab pots dated accordingly

• PAF era (1957-1960): Centralab pots should match pickup transition

Reading Gibson Pot Codes: Step-by-Step

Example Guitar: 1959 Gibson Les Paul Standard

Step 1: Access the Control Cavity

• Remove the back control cavity cover plate (2 screws)

• Carefully expose the pots and wiring

• Avoid disturbing original wiring if possible

Step 2: Identify All Four Pots

• Two volume pots (typically lower position)

• Two tone pots (typically upper position)

• Note position and function of each

Step 3: Read and Document Codes

Neck Pickup Volume Pot: 1345847

• 134 = Centralab manufacturer ✓

• 58 = Year 1958 ✓

• 47 = 47th week of 1958 (late November) ✓

Neck Pickup Tone Pot: 1345851

• 134 = Centralab manufacturer ✓

• 58 = Year 1958 ✓

• 51 = 51st week of 1958 (late December) ✓

Bridge Pickup Volume Pot: 1345903

• 134 = Centralab manufacturer ✓

• 59 = Year 1959 ✓

• 03 = 3rd week of 1959 (mid-January) ✓

Bridge Pickup Tone Pot: 1345908

• 134 = Centralab manufacturer ✓

• 59 = Year 1959 ✓

• 08 = 8th week of 1959 (late February) ✓

Analysis: These pots span late 1958 through early 1959, indicating guitar assembly in early-to-mid 1959. This is perfectly consistent with a 1959 Les Paul Standard.

Step 4: Cross-Reference with Other Features

• Serial number should be in 9xxxx range (1959)

• PAF pickups should have appropriate date codes or stickers

• Factory Order Number (FON) inside should correlate

• Long neck tenon and other 1959-specific features should be present

Advanced Authentication: What Pot Codes Reveal

Original vs. Modified Guitars

Pot codes immediately reveal modification history:

Scenario 1: All-Original Guitar

• All pots dated within same year or consecutive years

• All pots from same manufacturer

• Dates align with serial number and neck dates

• Value Impact: Premium prices for all-original condition

Scenario 2: Electronic Overhaul

• All pots dated significantly later than guitar

• Modern manufacturer codes (Asian manufacturers)

• May indicate complete rewiring

• Value Impact: 15-30% reduction depending on guitar and replacement quality

Scenario 3: Mixed Replacement

• Some pots original, some replaced

• Various date codes spanning decades

• Indicates piecemeal repairs over time

• Value Impact: 10-25% reduction depending on which pots and when replaced

Scenario 4: Period-Correct Replacement

• Replacement pots from same era as guitar

• Correct manufacturer and specifications

• May indicate professional restoration

• Value Impact: 5-15% reduction, generally acceptable to collectors

Geographic Manufacturing Clues

Pot codes can reveal interesting manufacturing patterns:

Centralab Dating Patterns (Gibson):

• Heavy production weeks align with Gibson's production schedules

• Seasonal patterns visible in week numbers

• Some years show clustering around specific weeks

Stackpole/CTS Patterns (Fender):

• Fender typically drew from multiple production runs

• Pots within a guitar often span 2-6 weeks

• Rare to find all pots from identical production week

Capacitor Dating

While not potentiometers, capacitors (caps) often have similar date codes:

Common Vintage Capacitor Types:

"Bumble Bee" Capacitors (Gibson):

• Black and yellow striped

• Used in vintage Les Pauls

• Sometimes have date codes

• Highly collectible when original

"Black Beauty" Capacitors (Gibson):

• All-black appearance

• Later period (1960s)

• May have date markings

Ceramic Disc Capacitors (Fender):

• Small ceramic disc shape

• Color-coded values

• Rarely dated but identifiable by style

Orange Drop Capacitors:

• 1970s introduction

• Instant indicator of non-original electronics in earlier guitars

Common Pot Code Scenarios and Solutions

Scenario 1: Pot Dates Don't Match Guitar Age

Question: "My 1965 Stratocaster has pots dated 1967. What does this mean?"

Answer: Your guitar has replacement pots, likely from a repair or modification done around 1967-1968. This is very common and doesn't mean your guitar is fake—just that the electronics have been serviced.

Value Impact: Depends on the guitar and current market. For a 1965 transitional Strat, replacement pots might reduce value by 10-20%. However, if the neck and body are original and authentic, substantial value remains.

What To Do: Document the replacement, be transparent when selling, and price accordingly. At Edgewater Guitars, we account for these modifications and still offer fair market prices based on the guitar's overall originality.

Scenario 2: Earlier Pot Dates Than Expected

Question: "My 1959 Les Paul has pots dated 1958. Is this normal?"

Answer: Yes, this is completely normal and actually expected. Pots manufactured in late 1958 would frequently be installed in guitars assembled in early 1959. This 2-6 month lag between component manufacture and guitar assembly is standard.

What's NOT Normal: A 1959 Les Paul with pots dated 1960 or later would be suspicious, indicating either later assembly (possible) or replacement (more likely).

Scenario 3: One Different Pot

Question: "Three pots are dated 1964, but one is dated 1972. What happened?"

Answer: A single pot was replaced—perhaps it failed, became scratchy, or was damaged. This is extremely common, especially on guitars that have been played extensively.

Value Impact: Minimal for player-grade instruments (5-10% reduction). More significant for collector-grade instruments where originality is paramount (10-20% reduction).

Collector Perspective: Some collectors insist on all-original components. Others accept individual component replacement as part of a guitar's "working instrument" history.

Scenario 4: All New Pots in Vintage Guitar

Question: "My supposed 1956 Telecaster has pots dated 1998. Is the guitar fake?"

Answer: Not necessarily. The guitar may have undergone complete electronic restoration. However, this requires careful authentication of neck, body, and hardware to confirm the guitar itself is genuine 1956.

Red Flags to Check:

• Neck date should read 1956

• Serial number should align

• Body wood and finish should appear period-correct

• Hardware should match 1956 specifications

• Neck pocket fit and stampings should be authentic

Verdict: Complete rewiring doesn't make a vintage guitar fake, but it does significantly impact value (30-40% reduction for complete electronics replacement).

Fender-Specific Pot Code Considerations

Stratocaster Pot Configurations

1954-1971 Stratocasters:

• 3 pots total (1 volume, 2 tone)

• 250K ohm resistance standard

• Typically Stackpole (304) or CTS (137)

Expected Variation: Pots within the same Stratocaster commonly span 4-12 weeks of production:

Example:

• Volume pot: 3045618 (week 18)

• Tone pot 1: 3045622 (week 22)

• Tone pot 2: 3045627 (week 27)

This 9-week span is completely normal and indicates Fender drew from rolling inventory.

Telecaster Pot Configurations

1950-1971 Telecasters:

• 3 pots total on most (1 volume, 1 tone, 1 blend or 3-way switch pot)

• 250K ohm resistance

• CTS (137) more common than Stackpole

Early Telecaster Note: 1950-1951 Broadcasters and early Telecasters sometimes used different wiring schemes, affecting pot count and type.

Precision Bass Pot Codes

1951-1971 Precision Bass:

• 2 pots (1 volume, 1 tone)

• 250K ohm resistance

• CTS (137) predominant manufacturer

Dating Consideration: With only 2 pots, you have less data for cross-reference. Neck date stamps become more critical for authentication.

Jazz Bass Pot Codes

1960-1971 Jazz Bass:

• 4 pots (2 volume, 2 tone) on stack-knob models

• 3 pots (2 volume, 1 tone) on later configurations

• 250K ohm resistance

• CTS (137) standard manufacturer

Stack Knob Models (1960-1961): The earliest Jazz Basses used concentric "stack knob" controls—highly collectible. Correct pot dating is essential for authenticating these rare instruments.

Gibson-Specific Pot Code Considerations

Les Paul Configurations

All Les Paul Models (1952-1960):

• 4 pots (2 volume, 2 tone)

• 500K ohm resistance

• Centralab (134) standard

• Occasionally IRC or other manufacturers in transition periods

Pro Tip: Gibson used audio taper (logarithmic) pots for volume, linear taper for tone. Original pots show this differentiation.

SG Configurations

1961-1971 SG Models:

• 4 pots (2 volume, 2 tone)

• 500K ohm resistance

• Centralab (134) through mid-1960s

• Transitioning to other manufacturers by late 1960s

ES-335/ES-345/ES-355 Configurations

1958-1971 ES Series:

• 4 pots standard (2 volume, 2 tone)

• 6 pots on Varitone-equipped models (ES-345, ES-355)

• 500K ohm resistance

• Centralab (134) predominant

Varitone Models: The additional 6-position rotary switch and associated circuitry makes authentication more complex. Look for period-correct Varitone components matching pot dates.

Pot Code Authentication Red Flags

Warning Signs of Counterfeits or Heavy Modification

Red Flag 1: Impossible Date Codes

• Pot dates after the guitar's known production period

• Example: 1959 Les Paul with 1975-dated pots

• Indicates either replacement or counterfeit guitar

Red Flag 2: Wrong Manufacturer

• Asian manufacturer codes in supposedly vintage American guitar

• Example: "ALPHA" pots in 1964 Stratocaster (Alpha didn't supply Fender then)

• Clear indicator of modern replacement

Red Flag 3: Too-Perfect Dates

• All pots dated the exact same week

• While possible, this is unusual and warrants extra scrutiny

• Fender and Gibson typically drew pots from multi-week inventory

Red Flag 4: Inconsistent Aging

• Pots show different levels of corrosion and aging

• Some pots appear old, others appear new

• Suggests piecemeal replacement over decades

Red Flag 5: Modern Pot Construction

• Plastic-backed pots in supposedly vintage instrument

• Split-shaft designs (rare in vintage)

• Modern terminal configurations

How to Spot Fake Pot Codes

Counterfeiters have become sophisticated, sometimes creating fake pot codes:

Fake Pot Code Techniques:

• Stamping modern pots with vintage dates

• Installing genuinely old pots from different guitars

• Artificially aging modern components

How to Detect Fakes:

• Examine stamping quality (should be crisp, period-appropriate depth)

• Check for aging consistency across all components

• Verify pot construction matches era (metallurgy, backing type, shaft design)

• Cross-reference with every other dating method available

Using Pot Codes with Other Dating Methods

Frequently Asked Questions About Pot Codes

Q: Can pot codes be faked?

A: Yes, sophisticated counterfeiters can stamp modern pots with vintage dates or install genuinely old pots from donor guitars. This is why pot codes must be verified alongside every other authentication method.

Q: Do replacement pots kill a vintage guitar's value?

A: No, but they do reduce it. The impact depends on:

• Which guitar (more important on six-figure Les Pauls)

• How many pots replaced (all vs. one)

• What replaced them (period-correct vs. modern)

• Overall originality of other components

Expect 10-30% value reduction depending on these factors.

Q: Should I never replace failing pots in my vintage guitar?

A: It depends on your goals:

• If keeping long-term as a player: Replace for functionality

• If selling soon: Consider repair before replacement

• If it's a high-value collector piece: Consult an expert first

Always save original parts even if you replace them.

Q: My pot codes don't match the guitar's serial number. Is it fake?

A: Not necessarily. Pot dates within 6-12 months of serial number dates are normal. Beyond that range suggests:

• Replacement pots (common)

• Factory assembly timing variations (possible)

• Authentication issues (requires more investigation)

Check neck dates and other features before concluding.

Q: Are certain pot manufacturers more valuable?

A: In collector circles:

• Stackpole pots on Fenders have slight prestige advantage

• Centralab on Gibsons is expected and correct

• CTS is equally correct on many Fenders

Functionally, these manufacturers are equivalent. The "premium" is psychological among collectors, not sonic.

Q: Can I date my guitar solely from pot codes?

A: Pot codes provide a date range (year and approximate quarter), but complete authentication requires:

• Serial numbers

• Neck dates (Fender)

• Pickup dates

• Hardware specifications

• Construction details

• Finish characteristics

Use pot codes as one piece of the dating puzzle, not the only piece.
