History of Gibson J-50
The history of a legendary machine known as a "good partner"

When discussing the Gibson J-50, Bob Dylan is an unavoidable figure. A J-50 is pictured on the cover of his debut album, "Bob Dylan." Recording took place on November 20th and 22nd, 1961, and the album was released on March 19th, 1962. It's also said to have been used on his next album, "The Freewheelin' Bob Dylan," and its warm sound can still be heard on recordings today. The following are some of the characteristics of the J-50 that can be gleaned from photographic materials:
Script logo
- Post-war Kluson octagonal tuner, open-back design (estimated)
Rectangular bridge
Long saddle
3-ply body cell binding

The combination of the script logo and rectangular bridge narrows the production year to 1946-1947. 1947 was a transitional period where both script and modern logos coexisted, but perhaps due to Dylan's influence or the original low production numbers, opportunities to see this particular model are extremely rare. However...

James Taylor is almost always mentioned as a singer-songwriter who favored the J-50. He himself has stated that he used the J-50 on his first three albums, "James Taylor (1968)," "Sweet Baby James (1970)," and "Mud Slide Slim and the Blue Horizon (1971)." The J-50 has a good balance of volume in the mid-to-low range and crispness in the high range, and its somehow high-quality, warm sound blends exquisitely with his singing voice.

What's striking is that the pickguard has been removed, confirming that this style was already in use in the late 1960s. Gibson underwent frequent specification changes in the 1960s, so the year of manufacture is also a point of interest. Looking at the photo, the area where the pickguard was removed is also painted, indicating that this is a guitar from the period when "the pickguard was attached after the body was painted." Gibson transitioned from thin large pickguards to thick large pickguards in 1964, and from that point on, attaching the pickguard afterwards became the standard. The owner himself has said that he purchased his J-50 in 1964, and considering the specification changes, it is highly likely that his J-50 is from 1964 (regular neck, 17-degree headstock angle, thick pickguard).

He is one of the guitarists who represented the British folk revival of the 1960s. He greatly expanded the expression of the acoustic guitar by incorporating blues, jazz, and even Moroccan and Indian musical language into traditional British folk. Symbolically, he popularized the DADGAD tuning, which popularized a playing style that develops modally based on open string drones. His signature song "Anji (Angi)" became a standard that followed and was carried on by Bert Jansch and Paul Simon. His major works include "The Guitar Player" (1963), "Folk Roots, New Routes" (co-written with Shirley Collins, 1964), and "Folk, Blues & Beyond" (1965), all of which cross-culturally connect folk, blues, jazz, and non-Western sounds. His influence spread to Bert Jansch, John Renbourn, Paul Simon, and Jimmy Page, and he played a decisive role in laying the foundation for British acoustic sound.

His J-50 can also be seen on the cover of his first album, "The Guitar Player." The specifications, including the small pickguard and the upper belly bridge with a short saddle, suggest that it was manufactured around 1953-1954.

Like Davy Graham, he is one of the guitarists who expanded the British music scene from the 1960s onward. Also around the same time, in 1966, he released "Bert and John," a collaborative work with Bert Jansch, and the following year, 1967, he formed Pentangle with Jackie McShee, Danny Thompson, and Terry Cox. In his 1968 album "Sir John A Lot (Of Merrie Englandes Musyk Thyng & Ye Grene Knyghte)," he reinterpreted William Byrd's "The Earle of Salisbury" on acoustic guitar, and in his next album, "The Lady and the Unicorn," he incorporated ballads by Guillaume de Machaut, thus venturing into medieval music as well.

John Renbourn is pictured holding a Gibson J-50 on the cover of his album "Another Monday." What ultimately convinced him to buy a J-50 was the cover photo of Davey Graham's "The Guitar Player," mentioned earlier. However, years later, when Renbourn met Graham himself, he learned that Graham had actually used a Martin guitar for the recording of that album. Apparently, Graham had mistakenly brought a different guitar case to a party the night before the album cover photo shoot, and therefore had no choice but to use the J-50 that was in the case for the photo shoot. This accidental image became Renbourn's motivation for purchasing the guitar, and it shaped the core sound of his later albums and tours. It's a truly fascinating episode that will go down in the history of fingerstyle guitar.

If asked in Japan, "Which singer-songwriter is a representative example of someone who has owned a Gibson J-50?", I would name Tadashi Kosaka as the closest to its origins. I will omit the details of how he acquired the J-50 and his relationship with Haruomi Hosono, and instead focus on the manufacturing year of the J-50 he used. The J-50 he acquired in the late 1960s featured a thick pickguard and an upper belly bridge with an adjustable saddle.
While the age range for this specification is quite broad, the parts used provide a clue. The introduction of thick pickguards began in 1964. Also, the tuning pegs are Kluson's "Single Line" Deluxe tuners, which have only one line of "KLUSON DELUXE" engraving. In 1965, the engraving on these tuners changed to a "Double Line" with two lines of "KLUSON DELUXE" lettering. In other words, the fact that it was the first year of thick pickguards and the last year of Kluson Single Line tuners makes it highly likely that this guitar was made in 1964.
In a conversation with Yuma Abe (never young beach) and Hama Okamoto (OKAMOTO'S), Haruomi Hosono mentioned, "Maybe Tadashi also bought a Gibson J-50 because of James Taylor's influence." By some twist of fate, the discovery that they may have been using the exact same model from the same year gave me a strange sense of connection and excitement.

Since his solo debut around 2010, he seems to have been using a small-bodied Gibson acoustic guitar (LG-1 or B-25 *the body binding looks like it's a single ply, so maybe an LG-1?*). Then, from the mid-2010s, he started using a Gibson J-50. The specifications of the small pickguard and the upper belly bridge with a long saddle suggest that it was manufactured sometime between 1948 and 1954, as this type of guitar had a long period of mixed production.
As far back as December 31, 2024, we were able to confirm its use on the Kohaku Uta Gassen (Red and White Song Contest). While the simple sound of the small-bodied version was lovely, the rich, full tone characteristic of the jumbo size is also irresistibly deep.

She is a modern and impressive singer-songwriter who uses vintage guitars. While she is also active in bands using electric guitars, her acoustic guitar performances are also breathtaking. For her solo performances, she mainly uses vintage Country Western and J-50 guitars. The J-50 is a 1965 model with a regular neck and a 17-degree headstock angle. As you can hear in her recordings, the appeal lies in the reassuringly deep bass that supports her singing voice. In addition to the sound, the scratches on the soundhole and around the pickguard are a testament to her and the J-50's journey together, and it has an appearance that would be ideal for anyone who loves Gibson and plays and sings.

This is a 1947 J-50, from around the time mass production began to be established. The logo is the modern type. It is thought that the logo was changed from the script logo to the modern logo around this time. It has a small pickguard and a rectangular bridge with a long saddle.RecruitThe tapered headstock, with its varying thickness at the tip and base, is sure to appeal to enthusiasts. The spruce top of the body has a golden sheen, and the wood used is exceptionally beautiful, with densely packed horizontal grain.

The neck block bears what is believed to be an extremely early factory order number (FON). The number "605," stamped in bold black letters, is a unique number assigned to the guitar's batch, while the number "30" to its right is said to be the number assigned to the individual guitar.

Upon examining the inside of the body, it's clear that while Gibson bridge plates are typically made of maple or plywood, this particular guitar clearly uses a spruce-like material. (Photo shows the guitar before repair.)

Furthermore, it can be seen that 12 spruce side ribbons (crack prevention) are attached to the back of the body's side.

The screws used for the truss rod cover and tuners are Phillips head, and it is believed that slotted screws were more common during this period, but several examples of 1947 models with Phillips head screws have been found.

It's often said that guitars from the Banner era (1942-1945) have thicker wood and are lighter, and this particular guitar, at 1.80kg, is also quite lightweight for a Gibson Jumbo. Furthermore, the top is only 2.4mm thick, and you can see the difference in thickness when comparing it to a 1960s model in a photograph.

This 1951 J-50 features a small pickguard and an upper belly bridge with a long saddle. Compared to the aforementioned 1947 model, several changes can be seen besides the bridge shape. First, the pickguard is more reddish, giving it a slightly brighter overall appearance. The taper on the headstock has been eliminated, and the thickness is now almost uniform. Internally, the bridge plate is made of solid maple, and the number of side ribbons has decreased from 12 to 10 (the four ribbons below the waist of the body have been reduced to three).
When you examine the details in this way, the differences in atmosphere even among the same J-50 model become even more apparent.

This 1954 model features a small pickguard and an upper belly bridge with a short saddle. Other notable features include Kluson Deluxe tuners (no lines) without the "KLUSON DELUXE" engraving.RecruitIt also has 19 frets (which changed to 20 in 1955), which is typical of this period.
Due to the small pickguard, natural finish, and white body binding, the body shape appears to be slightly bulging.

This particular model features a thin, large pickguard and a plastic bridge. The basic structure isJ-45 feature articleSince I've already mentioned it, I'll write down what I learned by comparing it to the 1951 model.

A clear difference in scale was observed when comparing it to the 1951 model. From the nut to the top of the saddle, the 1951 model was 7mm longer.

Upon closer measurement, I found a difference of approximately 2mm from the nut to the 12th fret (the center section was made longer during manufacturing), approximately 1.5mm from the 12th fret to the joint (the 1963 model has the neck joined closer to the body), 2mm in body size (the length from the bridge end to the body end was the same, so this affects the scale length), and approximately 1.5mm from the top of the bridge to the saddle contact point.

The 1963 model already had 20 frets. Logically, it wouldn't be surprising if the scale length was longer than the 1951 model, but actual measurements show it's actually shorter. This is extremely interesting. Since it's handmade, it's likely that the accumulation of minute errors during production will show up in the final measurements.

Looking at the comparison photos again, it seems there are still some differences, such as the color of the fretboard and the thickness around the neck joint.
