Martin D-45
from Wikipedia

The Martin D-45 is a steel-string acoustic guitar model made by C. F. Martin & Company. The model was manufactured from 1933 to 1942, and in a second production series since 1968. Martin originally made the guitar's sides and backs of Brazilian rosewood. Martins are ranked among the highest-quality, as well as among the most expensive guitars, and the D-45, regarded as one of the first "luxury guitars",[1] was listed in 2011 as the most valuable production-model guitar.[2]

Key Information

History

[edit]

First series, 1933-1942

[edit]

The first D-45 was a dreadnought guitar based on the Martin D-28 with luxury ornamentation (the "45" designation),[2] made especially for Gene Autry who, in 1933, ordered "the biggest, fanciest Martin he could."[3] This guitar is now encased in glass in the Gene Autry Museum of the American West in Los Angeles, California.[4] The next year, Martin made one for Jackie "Kid" Moore, a "12-year-old singing cowboy from Milwaukee, Wisconsin."[5] These first two had a 12-fret neck; most others (except for the 6th, made in 1937) made afterward had a 14-fret neck.[6] Two more were made in 1936 and two again in 1937;[6] the D-45 wasn't catalogued until 1938.[7] Other versions included a D-45S (with a special neck, 1939) and a D-45L (left handed, 1940).[6] The D-45 was the top model of the dreadnought line,[8] which also included the D-28 and D-18 models, priced much lower.

In 1942, as a result of World War II, Martin officially ceased production of the D-45 (as well as other Martin models such as the archtops).[6] This first series of D-45's consisted of only 91 instruments.[1]

Second series, from 1968

The luxurious D-45 resembled the less ornate D-28 model enough to entice entrepreneurial guitar builders and craftsmen to modify the latter to look like the former by adding a pearl border and changing the stamps on the neck block, so they could sell them as the more expensive model. One of those craftsmen was Mike Longworth, a banjo player from Tennessee, who Martin hired specifically to bring the D-45 back. The new D-45, released in 1968, cost $1,200 and was the most expensive flat-top steel-string guitar made in the United States at the time. By 1969, Martin sold twice as many D-45s as during the entire 1933–1942 run; customers included David Crosby and Jimi Hendrix.[1] In 1971, a 12-string model was made,[1] and in 1973, another one.[6]

Longworth also designed a more affordable model, the D-41, making sure that the pearl inlays were done in such a way that the guitar could not be modified to look like a D-45.[1] Since 1968, Martin has produced a number of special versions, including the C.F. Martin Sr. Commemorative D-45 (200 guitars in 1996) and the C.F. Martin Sr. Deluxe D-45 (91 guitars in 1996).[6]

Value

[edit]

Models produced between 1933 and 1942 (also referred to as "pre-war Martins") are among the most expensive production-model guitars ever made. A listing for $135,000 was noted in a 2005 publication,[9] and in 2011, a Vintage Guitar ranking of valuable guitars saw the D-45 (models made between 1936 and 1942) in first place, worth between $250,000 and $400,000.[2] George Gruhn remarked that pre-war D-45s fetch "more than 20 times as much as a recent issue D-45, even though there is relatively little difference in design."[10][11]

These dimensions promote even string tension and facilitate complex chord voicings across the 20-fret .

Production History

Pre-War Era (1933–1942)

The Martin D-45 originated in 1933 when Western singer commissioned to create a deluxe guitar, resulting in the first unit bearing serial number 53177 as a 12-fret variant with a slotted and custom pearl inlays including Autry's name. This special order reflected growing demand from Western performers for high-end instruments suited to stage and recording, positioning the D-45 as Martin's flagship with elaborate trim and premium appointments. From 1933 to 1942, Martin produced a total of 91 D-45 guitars, with the majority featuring 14-fret necks after the initial 12-fret models transitioned to the more common configuration by 1934. Rare variants included the D-45S special order in 1939, which introduced options like a sunburst finish, and the D-45L in 1940 with a long-scale neck, alongside other customs such as left-handed builds and personalized inlays. Marketed as the top-of-the-line model at a retail price of $300–$400, the D-45 appealed to professional musicians seeking superior projection and aesthetics, far exceeding the output of comparable models like the D-28. Production ceased in 1942 amid material shortages and government restrictions on non-essential manufacturing, particularly affecting the labor-intensive pearl inlays and exotic tonewoods. These early D-45s were prized for their warm, responsive tone derived from old-growth Brazilian rosewood back and sides paired with Adirondack spruce tops, enhanced by forward-shifted scalloped X-bracing for balanced volume and clarity. Hand-crafted with minimal automation in Martin's factory, each instrument exemplified the pinnacle of pre-war luthiery, contributing to their enduring reputation among collectors and performers.

Post-War Revival (1968–Present)

The Martin D-45 was reintroduced in 1968 under the direction of master inlay craftsman Mike Longworth, who was hired specifically to revive the model as the pinnacle of Martin's lineup during the folk-rock boom of the era. Priced at $1,200, it became the company's most expensive offering, featuring premium Brazilian rosewood back and sides paired with an Adirondack spruce top for exceptional projection and richness. This revival capitalized on the growing demand for high-end acoustics among performers like of , positioning the D-45 as a symbol of luxury craftsmanship. Production began modestly with approximately 67 units in 1968 and 162 in 1969, totaling 229 in 1968 and 1969 before expanding. Due to Brazilian export restrictions on beginning around 1970, Martin shifted to East Indian for the back and sides, maintaining the model's tonal integrity while adapting to regulatory changes. By 2005, post-war production had reached over 6,300 units, and with continued output at an estimated 350–450 units annually since then, the total exceeds 12,000 as of 2025. Key innovations included the introduction of the Vintage Tone System (VTS) in 2015, a process that thermally ages tops and bracing to emulate the broken-in of pre-war instruments, enhancing the D-45's vintage-like warmth without extended play-in time. In 2025, the Standard Series received a significant refresh, incorporating a neck taper for improved , a thinner , and refined bridge and heel design to boost playability and sustain. These updates, combined with scalloped forward-shifted Golden Era bracing, deliver balanced tone with enhanced responsiveness. Recent developments in 2025 extended to the Golden Era Reimagined series, which incorporates authentic pre-war-style scalloped bracing with wood-to-wood contact via hide glue for superior projection and , bridging historical accuracy with modern . Limited runs have also integrated alternatives like Hawaiian koa for back and sides, reducing reliance on while preserving the model's ornate aesthetic and bold voice.

Variants and Editions

Style Variations

The Martin D-45 features a standard body style, designated as D-14 in Martin's , which delivers robust volume and balanced tone through its expansive soundboard and X-bracing. Rare body style options include the 12-string D12-45 variant, produced in limited quantities from 1969 to 1987 (approximately 83 units), providing a fuller, resonant chime ideal for rhythmic strumming. Early pre-war examples occasionally incorporated a 12- , as seen in the initial two D-45s built in 1933 and a custom 1937 order, resulting in a compact upper bout and altered string tension compared to the typical 14- configuration. Left-handed models, labeled D-45L, were first introduced in , with ongoing production to accommodate left-handed players. Inlay patterns on the D-45 adhere to the ornate Style 45 aesthetic, utilizing shell for hexagonal markers on the , along with pearl and abalone borders on the top, back, sides, and , creating a visually striking contrast against the body. The design evolved from inlays featured in the 1938 catalog to the signature large hexagons by , establishing the model's enduring elegance. Post-1970s production saw minor simplifications in some appointments amid Brazilian restrictions, shifting to East Indian while preserving core elements, though full Style 45 detailing persisted in standard runs. Finish options transitioned from tops on select pre-war instruments to natural gloss finishes as the norm by the , emphasizing the grain of Sitka tops and back and sides. The D-45 maintains a standard scale length of 25.4 inches on its , promoting clear articulation and strong projection for and strumming styles. Occasional short-scale iterations at 24.9 inches appear in custom or variant builds, facilitating lighter string tension and enhanced fingerstyle playability. Since 2004, Martin has incorporated VTS (Vintage Tone System) or torrefied Sitka tops in select D-45 models, such as the D-45V, to emulate the mellowed of pre-war aged wood by thermally processing the spruce. Hardware refinements on the D-45 evolved from Kluson open-gear tuners on pre-war and early examples to Schaller M6 enclosed tuners starting in the late and predominant through the , enhancing precision and durability. Modern updates post-2020 include ergonomic features like a 1/4-inch beveled on certain production runs, reducing contact pressure on the body edge for prolonged comfort during performance.

Limited and Signature Models

The Martin D-45 has inspired several limited editions that pay homage to its heritage, often incorporating rare tonewoods and bespoke appointments to celebrate key milestones or figures in the model's history. One notable example is the C.F. Martin Sr. 200th Anniversary Commemorative D-45, produced in a run of 200 instruments to mark the birth of the company's founder in 1796; these feature premium East Indian rosewood back and sides, high-grade Sitka spruce tops with forward-shifted scalloped bracing, and Style 45 inlays for a rich, balanced tone reminiscent of pre-war examples. Similarly, the D-45CFMB Deluxe variant, limited to 91 units, elevates this with Brazilian rosewood and extensive detailing, including pearl inlays, to honor the founder's legacy through exceptional craftsmanship. Signature models further distinguish the D-45 line by tailoring designs to influential artists. The 1999 D-45SS Stephen Stills Signature Edition, produced in a limited run of 91 guitars, replicates aspects of Stills' own 1939 pre-war D-45, utilizing select Brazilian back and sides paired with European Alpine spruce tops, hexagonal fret markers, and a custom-inlaid Southern Cross pickguard for enhanced visual and acoustic appeal. The 2018 D-45 John Mayer Signature Edition, limited to 45 units, incorporates Guatemalan back and sides with an Engelmann spruce top featuring aging toner and forward-shifted scalloped X-bracing, delivering articulate clarity and projection suited to Mayer's playing style. Recent specials emphasize innovation and while maintaining the D-45's deluxe ethos. The 2025 OM-45, introduced as a companion to the dreadnought D-45, adopts an model body with a 25.4-inch scale length, East Indian rosewood back and sides, Sitka spruce top, and pearl inlays, offering enhanced clarity and balance in a more compact form. Project 91, a series of 91 pre-war D-45 replicas introduced in 2025, faithfully recreates specific historical serial numbers using rare Brazilian rosewood, vintage-inspired bracing, and details like 12-fret necks or double pickguards to capture the golden-era sound. These editions typically limit production to 50-200 units to ensure exclusivity, often featuring custom engravings or inlays that nod to the model's storied past.

Collectibility and Value

Pre-War Models

The pre-war Martin D-45, produced between 1933 and 1942, represents the pinnacle of rarity in vintage acoustic guitars, with only 91 instruments ever built by . Of these, approximately 72 are accounted for in the current market, owing to the model's limited production run and the durability of its construction. This scarcity is amplified by intense demand from collectors, driven by the use of premium tonewoods such as Brazilian rosewood for the back and sides and Adirondack spruce for the top, materials that contribute to its legendary tonal qualities and aesthetic appeal. Valuation trends for these guitars have shown significant appreciation over time, reflecting their status as the "" of acoustic instruments. Auction highs have reached $250,000 or more, with asking prices up to $375,000 as of 2025 for exceptional examples like a newly discovered 1942 model. By 2025, estimates for pristine, original-condition pre-war D-45s range from $300,000 to $500,000 or more, with recent sales exceeding $1 million for exceptional specimens. In 2025, Martin launched Project 91, creating 91 replica guitars matched to each original pre-war , priced significantly lower than originals, which may influence long-term collectibility dynamics. Factors such as —particularly lower numbers from the early —and complete originality heavily influence pricing, often commanding premiums of 25% or greater over modified instruments. Refinished or oversprayed examples, while still valuable, typically sell in the $150,000 to $200,000 range. Condition assessment is paramount in evaluating pre-war D-45s, as originality directly impacts both playability and market value. Collectors place a premium on unrestored necks, intact internal braces, and minimal repairs, with all-original components like frets, tuners, bridges, bridge plates, and finish potentially increasing value by up to 25% or more. Common age-related issues include sinking tops due to decades of string tension and environmental exposure, as well as potential cracks or wear from use, which can diminish value if not professionally addressed. Professional appraisals from multiple experts are recommended to verify condition and authenticity before any transaction. These guitars are primarily traded through high-end auctions and specialized dealers, such as and Gruhn Guitars, where their investment appeal as the ultimate acoustic collectible drives consistent demand. The pre-war D-45's status fosters annual appreciation rates of 10–15% in strong markets, outpacing many comparable vintage instruments and underscoring its role as a blue-chip asset for serious investors.

Post-War Models

The post-war Martin D-45, reintroduced in after a 26-year hiatus, marked a significant increase in accessibility compared to the rare pre-war originals, with production exceeding 4,000 units by the and continuing into the present day. This revival allowed a broader range of musicians and collectors to own the flagship , though values have fluctuated based on material availability and market dynamics. As of 2025, 1968–1970s D-45 models generally sell for $7,000–$15,000 in good to excellent condition, with rarer 1968–1969 examples featuring Brazilian rosewood often commanding $30,000–$50,000 due to their limited production of just 67 units in 1968 and 162 in 1969. Modern standard D-45 guitars retail for $8,000–$10,000, exemplified by the 2025 model's list price of $9,799, which incorporates premium tonewoods like East Indian rosewood and Sitka spruce. Several factors influence post-war D-45 values, including the back and sides material—Brazilian rosewood used exclusively from 1968 to 1969 provides a tonal complexity and scarcity premium over the East Indian rosewood adopted from 1970 onward due to supply restrictions. Condition and originality are critical, with crack-free examples retaining 20–50% more value than repaired or refinished ones, while features like Vintage Tone System (VTS) torrefied tops on select modern builds can boost prices by 20–30% for enhanced vintage-like resonance. Limited and signature editions, such as those with custom inlays or celebrity collaborations, typically sell for 1.5–2 times the standard model's price. Market trends for post-war D-45s reflect initial depreciation in the 1970s from overproduction during Martin's expansion era, when list prices around $1,200–$1,500 led to secondary market values dipping below $5,000 by the 1980s amid economic pressures on the guitar industry. A revival occurred in the 2000s, fueled by growing interest in vintage acoustics and endorsements from high-profile musicians like John Mayer, whose custom D-45 signature model highlighted the design's enduring appeal and drove demand for both new and used examples. The 2025 refresh, featuring Golden Era (GE) top bracing for improved sustain and a refined neck profile for better playability, has further stabilized values by aligning modern production closer to vintage specifications. Among collectors, early D-45s from 1968–1975 are highly prized for their "vintage vibe," attributed to Brazilian rosewood and hand-voiced construction during a transitional production period, earning them a B+ collectibility rating. In contrast, the more mass-produced models, while less rare and valued primarily for their reliable playability and bold projection, hold steady appeal at $6,000–$8,000 without the same speculative premium.

Notable Owners

Pre-War and Early Owners

The Martin D-45's pre-war era saw its initial adoption by prominent figures in the burgeoning country and western music scene, with commissioning the very first example in 1933. As the "" and a rising star in Hollywood films and radio broadcasts, Autry ordered a custom 12-fret model (serial number 53177) featuring pearl inlays, including his name on the , to enhance his stage presence during performances. This guitar, built with Brazilian rosewood back and sides and an Adirondack spruce top, became a signature instrument for Autry, symbolizing the model's luxurious appointments tailored for visual impact in early sound films and live shows.

The guitar remained in the Wills family legacy for decades before entering private collections, underscoring its enduring cultural significance in mid-20th-century American music. Autry's ownership played a pivotal role in driving initial sales of the D-45 to other Hollywood performers and singing cowboys, such as Nolan "Cowboy Slim" Rinehart, highlighting the model's appeal as a for stage artists in the 1930s. Ownership among performers was rare, limited by the guitar's high cost of $200—equivalent to about a month's wages for many musicians—and its targeted marketing to elite entertainers. These early D-45s embodied luxury in the country/western milieu, with only 91 produced between 1933 and 1942, though documentation remains sparse due to inconsistent record-keeping from the era's small-scale luthiery and wartime disruptions.

Post-War and Modern Musicians

The revival of the Martin D-45 in 1968 marked a significant moment for the model, with early adopters from the rock and folk scenes helping to elevate its status among musicians.
