|Even if this headstock didn’t say “Made in Japan,” the “J” that begins the serial number indicates that it was.|
The serial number on your modern Gretsch guitar or bass contains specific information about where and when it was made. This allows you to accurately date a modern Gretsch guitar by its serial number.
By modern, by the way, we mean since 2003, which is when Gretsch serial numbering took its current form. Various other serial numbering systems existed before then that stretch far back into Gretsch history—all the way back to the very earliest Gretsch guitars of the 1930s. We’ll cover those older serial numbering systems in another installment.
As for the present, the modern system is quite simple. Gretsch serial numbers typically appear on the back of the headstock and begin with a two-letter prefix code indicating the country of origin and specific manufacturing facility, followed by numbers indicating year and month of manufacture and sequential order of manufacture.
“JT” is most common among the several two-letter country/factory prefixes, signifying Japan (J) and its Terada (T) factory. Others are “CS” (U.S. Custom Shop), “CY” (China, Yako facility), “JD” (Japan, Dyna Gakki facility), “JF” (Japan, Fuji-Gen Gakki facility), “KP” (Korea, Peerless facility) and “KS” (Korea, Samick/SPG facility).
After the two-letter prefix, two digits designate the year of manufacture; the next two designate the month of manufacture, and the remaining four digits designate the instrument’s sequential number among all models built that year. Of those last four sequential-order digits, 0001 through 0100 designate prototype and one-off models, sample instruments and other special instruments; 0101 through 9999 designate all regular production models.
For example then, a modern Gretsch serial number such as “JT07115922” would indicate that the instrument was built in Japan (J) at the Terada factory (T); that it was built in 2007 (07) in November (11); and that it was the 5,922nd production-model instrument made that year. Similarly, “JT12030040” would indicate a non-regular-production instrument built in March 2012 at the Terada factory in Japan, and that it was the 40th among the special-run instruments made that year.

Every once in a while when exploring the Gretsch world, you’ll run across mention of the “Baldwin era” or the “Baldwin years.” What does this term refer to?
Generally speaking, people use it to refer to Gretsch in the 1970s. More specifically, however, it refers to the period when the Baldwin Piano Company owned Gretsch, which was substantially longer—from summer 1967 to early 1985.
The Baldwin era is a much-maligned period in Gretsch history. The term is often used in an unflattering light to denote generally neglectful Baldwin rule that resulted in a decline in quality, unpopular new instruments, corporate upheaval and dwindling sales that ultimately led to Gretsch guitar production being shut down altogether in 1981.
Gretsch had been a family-run company ever since Friedrich Gretsch founded it in New York in 1883. But in the mid 1960s, then-president Fred Gretsch Jr. purportedly found himself with no heir interested in running the company and decided to sell. Baldwin, riding high at the time and spurred by its 1965 acquisition of U.K. guitar maker Burns, sought to acquire an established U.S. guitar maker and duly turned its attention to Gretsch. The sale was completed on July 31, 1967.

What’s the deal with the zero fret found on some Gretsch guitars? What is it, why is it there and what does it do?
A “zero fret” is an extra fret located directly in front of the nut. You don’t often see them these days, although they were once fairly commonplace. Regarded today as an antiquated feature, they nonetheless still appear on a small number of instruments as an item of vintage-style authenticity.
Nonetheless, a zero fret isn’t merely a cosmetic touch—it does serve a subtle purpose appreciated by discerning players. In effect, it takes over the role of the nut in determining string height above the fingerboard. A zero fret can even out string action even more uniformly than the nut.
It’s easy to understand how the zero fret achieves this. On most guitars and basses, the nut serves as the anchor point for the vibrating length of the string at that end of the instrument (the bridge saddles serving the same function at the other end of the instrument) and as the string “spacer.”
The slots cut into the nut are of a generally uniform depth, but there can be very slight variations, which in turn produce very slight variations in the height of each individual string above the fingerboard. Guitarists with a discerning fretting hand feel may be able to detect such small variances.
The zero fret eliminates these variances and uniformly evens out string height even more finely because all the strings rest on it as they pass over it, with the nut relegated solely to its role of spacing the strings apart evenly across the width of the fingerboard.

What is trestle bracing, and what advantages does it offer on Gretsch guitars that feature it? Is it a modern development or a vintage design?
Good questions. The short answer to all of the above is that trestle bracing is a distinctive bracing system used inside certain Gretsch hollow-body guitar models that improves tone by increasing sustain and decreasing feedback. Gretsch developed it and first used it in the late 1950s.
Trestle bracing is a special extra. Most Gretsch hollow-body guitars and basses don’t have it. Rather, most Gretsch hollow-body instruments use a simpler internal support method called sound-post bracing, in which a vertical wooden dowel located directly under the bridge connects the top of the guitar to the back. The sound post itself doesn’t add much mass, so it affects sustain hardly at all. And since the sound post takes up very little space inside the guitar, the feedback characteristics of the body remain largely unchanged.
Far more substantial than sound-post bracing, trestle bracing consists of two bridge-like spruce braces with a wide “U” shape that are in effect trestles (hence the name). These run parallel to each other down the center of the instrument interior from the neck joint to the center of the body, ending directly under the bridge. They’re between the f holes, just beneath the sides of the pickups and bridge.
Since each rigid trestle brace has two “feet,” there are four points of attachment that are glued to the back of the guitar (versus one point of attachment for sound-post bracing). Originally, in the late 1950s and early 1960s, each of the four feet had “pilings” that served as the glued points of attachment with the back; modern-era trestle bracing dispenses with these.
The upper portions of the trestles are glued to the longer tone bar braces that also run in parallel down the underside of the top well past the bridge (and to which the pickups are fastened). This entire arrangement stiffens the top much more than a sound post does with its single point of attachment, aiding in control over feedback.
The great advantage of trestle bracing is that it effectively enables a hollow-body guitar to respond more like a solid-body guitar while preserving classic hollow-body tone. That is, it offers notably greater sustain and control over feedback due to the increased mass (more wood), the increased dampening of the top, and the much more substantial coupling of the top to the back.
As with several other innovations, Gretsch developed trestle bracing in the late 1950s at the behest of Chet Atkins. The great guitarist sought more sustain from his namesake 6120 hollow-body model and also wanted to subdue the feedback typical of electric hollow-body guitar design. Atkins worked with Gretsch’s Jimmie Webster and with inventor/engineer Ray Butts in devising several improvements for Gretsch guitars. Trestle bracing was one of these; it debuted in 1958 among a suite of new features including the upper-bout tone switch, “Neo-Classic” fingerboard inlays and Butts’ Filter’Tron pickup, one of the world’s first humbucking pickups (if not the first humbucking pickup).
Trestle bracing remained in use over the next few years, evolving slightly along the way. It was usually fashioned from spruce, although this wasn’t always consistent in the original era. It disappeared with the arrival of the thinner Electrotone body style in the early 1960s.
With the re-emergence of Gretsch in the modern era, trestle bracing was meticulously researched and offered once again as an authentic and tonally superior original-era design touch in several guitar models. It is a major feature on all Brian Setzer guitars and other select models, typically (but not always) referred to as “1959 trestle bracing.”

One of the things that makes Gretsch guitars stand out from the rest of the pack is the unique tailpiece options the company has utilized over the years.
Of course, not all guitars boast one of these metallic accoutrements, but the ones that do seem to suggest a souped-up elegance. Both utilitarian and aesthetically-pleasing, here is a look at the main tailpieces you’ll find on a Gretsch guitar.
Developed by Paul A. Bigsby, these vibratos allow the player to bend the pitch of notes or chords with their pick hand with the help of a spring-loaded arm called a whammy bar or tremolo.
Available on Gretsch guitars since the 1950s, the device also makes sure the instrument stays in tune while adding those bending effects. Bend the arm down toward the guitar and the strings will loosen, lowering their pitch. Release the arm, and it’s back to normal.
You can see Bigsby Vibrato Tailpieces on the 1958 Chet Atkins Country Gentleman, the G6118T-LTV 130th Anniversary Jr., the 1959 Chet Atkins Solid Body and the Duane Eddy Signature Hollowbody, among several others. (more…)
