1970s Martin Guitars: Why the 'Dark Years' Deserve a Second Look
1970s Martin Guitars: Why the “Dark Years” Narrative Is Wrong and Your Guitar May Be Worth More Than You Think
Last updated: October 2026
The 1970s Martin Myth vs Reality
For decades, the vintage guitar community has dismissed 1970s Martin guitars as products of the company’s “dark years,” a period supposedly characterized by declining quality, cost-cutting, and instruments unworthy of the Martin name. This narrative, while containing kernels of truth about early 1970s production challenges, has created one of the most significant undervaluation opportunities in the acoustic guitar market. The reality is far more nuanced, and far more favorable to 1970s Martin owners than the conventional wisdom suggests.
What actually happened in the 1970s:
Early 1970s (1970-1973): Genuine production challenges as Martin scaled rapidly. Higher demand led to faster production schedules, some inconsistent quality control, thicker finishes on some examples, and growing pains. This is the period that earned the “dark years” reputation.
Mid 1970s (1974-1976): Martin actively addressed quality issues. Construction improvements, better quality control, return to more traditional methods. Significant improvement over early decade.
Late 1970s (1977-1979): Quality largely restored to traditional Martin standards. Consistent construction, improved finishes, better hardware. Many late 1970s Martins are genuinely excellent instruments.
Why the “dark years” narrative is misleading:
Sample Bias: Poor early-1970s examples are disproportionately discussed, while good 1970s Martins get ignored
Unfair Comparison Standard: Comparing 1970s production to prewar instruments that cost many times more is unreasonable
Entire Decade Unfairly Tarred: Late 1970s quality improvements are ignored in blanket “1970s were bad” dismissals
Individual Variation: Even in the early 1970s, many excellent instruments were produced; quality varied guitar-to-guitar, not uniformly bad
Market Undervaluation: The negative narrative has suppressed 1970s Martin pricing to levels that represent genuine value
The bottom line: a sound, original 1970s Martin is still a solid-wood Martin, and it sells for a fraction of a 1960s Brazilian rosewood example. That is why one is worth a proper look rather than a blanket dismissal.
In Edgewater’s experience buying vintage Martin guitars across Ohio and the Midwest, 1970s Martins are the most commonly dismissed instruments we evaluate. Many owners have been told “it’s from the ‘70s, so it’s not worth much,” when in reality, individual assessment reveals excellent instruments that have been undervalued by blanket decade-based dismissal. We evaluate every 1970s Martin individually, assessing construction quality, bracing, top responsiveness, finish condition, and playability rather than applying decade-based prejudice.

Model | Reverb sold-price guide, 1970 to 1984 | Recent Reverb sales |
|---|---|---|
D-18 (mahogany) | $1,341 to $2,386 (387 orders) | $1,150 to $2,895, most $1,500 to $1,800 (Aug to Oct 2026) |
D-28 (Indian rosewood) | $1,785 to $3,148 (523 orders, natural and sunburst) | $1,999 to $3,000, most $2,300 to $2,700 (Aug to Sep 2026) |
D-35 (Indian rosewood, three-piece back) | $1,497 to $2,700 (501 orders) | $1,600 to $2,500 (Jul to Aug 2026) |
Where those numbers come from: Reverb's sold-price guides for the 1970 to 1984 D-18, the 1970 to 1984 D-28 and the 1970 to 1984 D-35, viewed October 2026, Good to Mint condition only. Asking prices on the same pages run higher, often $2,200 to $4,500 for a D-28, but asking is not selling, so use sold prices as the benchmark.
Edgewater's cash offer on a guitar like that would typically land around 20% under those sold figures, and lower for cracked, refinished or heavily repaired examples. A well-done neck reset is normal maintenance on a guitar this age. Condition and originality move the number more than the exact year, so the accurate answer for yours is a free appraisal.
Why 1970s Martins sell for less than 1960s ones
Three things set the gap. Indian rosewood replaced Brazilian on the D-28 and D-35 from 1970, a large rosewood bridge plate replaced the small maple one in 1968 and 1969, and Martin built far more guitars, a record 22,637 in 1971. A 1960s Brazilian rosewood D-28 is a collector guitar; a 1970s D-28 is a player's guitar priced like one. Our D-28 and D-18 value guide covers the 1931 to 1969 guitars, and the D-35 value guide covers 1965 to 1969.
What Changed in the 1970s (And What Didn’t)
Every 1970s D-18, D-28 and D-35 shares a set of changes that separate it from the 1960s guitars:
Rosewood: Martin moved its rosewood models from Brazilian to East Indian rosewood in late 1969, and standard production was on Indian rosewood from the start of 1970. A 1970s D-28 or D-35 has Indian rosewood back and sides; the D-18 stays mahogany.
Bridge plate: in April 1968 Martin replaced the small maple bridge plate with a rosewood one, and by 1969 the plate was much larger. That large rosewood plate stayed on standard models through the late 1980s, so every 1970s D-18, D-28 and D-35 has it. Many players and collectors hear it as a less lively top, and it is one reason these guitars price below 1960s examples.
Bracing: straight, non-scalloped X-bracing, the standard since the mid-1940s. Scalloped bracing came back with the herringbone HD-28 in 1976.
Neck: a non-adjustable square steel tube replaced the T-bar in 1967 and stayed until adjustable truss rods arrived in 1985. These necks can slowly pull into an up-bow, one reason so many 1970s Martins have had a neck reset.
Pickguard: black pickguards replaced tortoise in early 1967. In the 1970s the guard was glued to the bare top and lacquered over; as it shrinks it can crack the top beside it, the familiar Martin pickguard crack.
Binding: white plastic binding on the D-28 and D-35, black on the D-18.
Production: Martin built more guitars than ever, a record 22,637 in 1971, including about 5,500 dreadnought-size guitars against 507 dreadnoughts in 1961. That supply is a big part of why 1970s examples are common and sell for less.
The D-35 took over: introduced in 1965 with a three-piece back, the D-35 became a best seller. Fretboard Journal reports that in 1975 Martin made 6,260 D-35s against 4,996 D-28s.
What did not change
The basic recipe stayed the same: a solid Sitka spruce top, solid rosewood or mahogany back and sides, X-bracing, and the serial number stamped on the neck block, visible through the soundhole.
How to Evaluate a 1970s Martin
What to Check (Individual Assessment)
Top Responsiveness: Tap the top: responsive, resonant tops indicate good bracing and construction regardless of decade. Dull, dead-sounding tops indicate poor construction or damage.
Finish: look for the original lacquer. Checking and light crazing are normal with age; overspray or a refinish lowers value.
Bracing Quality: Inspect through the soundhole: well-fitted, cleanly executed bracing indicates quality construction. Sloppy or inconsistent bracing indicates production-line issues.
Neck Angle and Action: Proper neck angle critical for playability and tone. Many 1970s Martins need professional neck resets after 50+ years, and this is normal aging, not a quality defect.
Wood Quality: Indian rosewood quality varies; the best 1970s examples have excellent figure, density, and tonal character approaching Brazilian. Average examples are plain but functional.
Overall Construction: Check binding fit, fret work, bridge attachment, nut quality, tuner function. Individual variation tells you more than decade of production.

Frequently Asked Questions
What is a 1970s Martin D-28 worth?
Reverb's sold-price guide puts 1970 to 1984 D-28s at about $1,785 to $3,148, and recent sales ran mostly $2,300 to $2,700. Edgewater's offer usually lands about 20% under sold prices, lower for cracked or refinished guitars.
What is a 1970s Martin D-18 or D-35 worth?
Reverb's guide shows about $1,341 to $2,386 for a 1970 to 1984 D-18 and about $1,497 to $2,700 for a D-35. Clean, original examples sit at the top of those ranges.
Why are 1970s Martins worth less than 1960s ones?
Indian rosewood replaced Brazilian from 1970, a large rosewood bridge plate came in during 1968 and 1969, and Martin built record numbers of guitars, 22,637 in 1971 alone. Together those keep 1970s prices far below Brazilian rosewood 1960s examples.
When did Martin switch from Brazilian to Indian rosewood?
In late 1969. Standard production used East Indian rosewood from the start of 1970, so a 1970s D-28 or D-35 has Indian rosewood back and sides.
Does a neck reset hurt a 1970s Martin's value?
A well-done neck reset is normal maintenance at this age, and many 1970s Martins have had one because the square steel tube in the neck can let it pull forward over time. Cracks or a refinish move the price more.

Recently Purchased: 1970s Martin Case Study
The Guitar: 1978 Martin D-28, a late 1970s example the owner assumed was “worthless because it’s from the dark years.” All-original with solid Sitka spruce top, Indian rosewood back/sides, thin lacquer finish (not thick polyester), well-executed X-bracing, excellent top responsiveness on tap test, original Grover tuners, original bone saddle and nut. Serial number confirmed 1978 production. No cracks, no neck reset needed, no modifications. 48 years of wood aging producing warm, open, resonant tone.
The Seller: Owner in Sandusky, Ohio. Had been told by two shops “it’s a ‘70s Martin, not worth much.”
The Transaction: Edgewater evaluated the guitar individually. Top tap test revealed excellent resonance: a well-constructed instrument with good bracing. Thin finish confirmed (not thick polyester). Indian rosewood showed good figure and density. Construction quality consistent throughout: binding tight, frets good, bridge solid. This was a GOOD 1970s Martin, not the “dark years” caricature.
The Outcome: “Two shops told me ‘1970s Martins are junk.’ Edgewater actually played the guitar, tapped the top, looked inside at the bracing, and told me ‘this is a well-built late-1970s D-28 — Martin had largely solved their quality issues by 1978.’ They explained that 48 years of aging on solid spruce and rosewood creates genuine tonal value regardless of decade prejudice. Their offer was more than double what the shops quoted.”
