Gibson / 1964 J-45
“The J-45 Embracing New Specification Changes”
Since the J-45 debuted in 1942, it has undergone numerous specification changes, delighting us with a wide variety of appearances and tones.
1964 was also the year that brought further changes to the body’s appearance.
—The Year the Thick Pickguard Was Introduced
The top is made of spruce and finished in a cherry sunburst color.
Over time, it has developed a pale orange hue, giving it a gentle appearance.
This cherry finish was introduced in 1962 and remained in production until 1967.


The sides and back are made of mahogany and finished in a vibrant cherry color. You can appreciate the bold grain pattern characteristic of
mahogany.


The fingerboard is made of rosewood with a dense grain pattern. The
white celluloid dot position markers stand out beautifully.
The nut width is approximately 42 mm.


The neck is made of mahogany, and starting in the 1960s, the neck profile was changed to a slimmer shape.
For those who find the thicker 1950s neck profiles uncomfortable, models from 1963 onward are particularly recommended.


The upper belly bridge is made of rosewood and features a matte-finish ceramic adjustable bridge. The switch to matte-finish
ceramic saddles was a specification change introduced around 1963.
Although plastic bridges were also used intermittently from 1963 to 1964, this instrument features a wooden bridge.


While the specification changed from a small pickguard to a large pickguard in 1955, a further change was introduced this year.
Whereas large pickguards approximately 0.5 mm thick were used until 1963, the specification was changed to pickguards approximately 1.0 mm thick starting in 1964.
The pickguard is a transparent one with a marble pattern featuring a red base color.


The headstock features a Gibson silkscreen logo.
The headstock angle is 17 degrees.


The guitar is equipped with a set of three Kluson Deluxe tuners.

The soundhole rosette was changed to a double-ring design starting in 1963;
prior to 1963, it was a single line.
Even these minor changes are important clues for determining the instrument’s age.


This guitar has no cracks and is characterized by its beautifully faded cherry finish.
It’s quite rare to find a guitar in such excellent condition. As this is a rare example from the first year the pickguard was changed to a
thicker version, we encourage anyone who’s been searching for one to give it a try.
