GretschTech: Picking the Pickups


DynaSonic. HiLo’Tron. Filter’Tron.

No, those aren’t the futuristic names of a new group of superheroes.  In fact, they are three of the main types of pickups that are used in Gretsch guitars.  Whether you’re looking for twang, bite, jangle, or chime, chances are one of these babies will do the trick.

In the latest edition of GretschTech, we take a look at some of the pickups that were found on the Gretsch guitars of years past. (more…)

GretschTech: “G Arrow” Control Knobs


One of the most distinctively stylish features of Gretsch guitars past and present is the “G arrow” control knob. If you already own a Gretsch, you know what we’re referring to—the volume and tone knobs on your instrument, which are in most cases adorned with an engraved later “G” pierced by an arrow. This was an early but not original development.

Gretsch’s earliest electric guitars of the late 1940s and early 1950s—mostly Hawaiian lap steel and arch-top Electromatic models—had plain control knobs. When the original golden age of Gretsch electric guitars began in earnest in 1954, a much more distinctive control knob style was adopted, quite unlike that of contemporaries such as Fender and Gibson. 1954 saw the introduction of gold- and chrome-plated brass knobs with plain unadorned tops and a crosshatched pattern around the circumference.

GretschTech: Fingerboard Inlays


Gretsch guitars and basses are loaded with distinctively stylish features that all contribute greatly to their very “Gretsch-iness.” From pickups to bridges, trem arms to tailpieces, and control knobs to switching layouts, few instruments are the sums of their parts – and much more – quite like a Gretsch.

This is especially evident right at your fingertips, because Gretsch instruments have a fingerboard inlay tradition all their own. Several of the styles adopted in the 1950s are still in use today and have long since become distinct Gretsch traditions. Here’s a look at what you’ll find on Gretsch fingerboards today: (more…)

GretschTech: Switches Everywhere …


How does the switching work on Gretsch guitars?

Of the approximately 100 Gretsch electric guitar and bass guitar models available today, about half of them have a single switch on the upper bout. The other half have two switches on the upper bout. A dozen or so models even have a switch on the lower bout.

Welcome to the wonderfully idiosyncratic world of Gretsch switch configurations, which can differ quite substantially from other guitars. Once you fully understand what’s going on under your Gretsch guitar’s hood, we think you’ll agree that the switching layouts are really quite sensible. Ingenious, even. Here’s the deal …

GretschTech: Gretsch Bridges


Among their many distinctive features, Gretsch electric guitars have been known for decades for a variety of highly individual bridge designs. The history of these bridges is as colorful and interesting as the Gretsch instruments they’re part of, and many of the original-era designs live on today in modernized form.

Today’s four most prevalent bridge types for Gretsch electric guitars and basses are the Adjusto-Matic™, Space Control™, Rocking Bar and Synchro-Sonic™ bridges. There are other types here and there, but those are the big four. Here, in chronological order, is a look at each one:

Synchro-Sonic™ Bridge

Modern Gretsch Synchro-Sonic bridge.

Introduced on Gretsch guitars in 1951, the Synchro-Sonic bridge was a welcome innovation in that it was one of the first guitar bridges—if not the very first—to feature independent intonation adjustment for each string (it preceded the Gibson Tune-O-Matic bridge by about a year).

Back in the early 1950s, it was originally named the “Melita” Synchro-Sonic after its designer, Sebastiano “Johnny” Melita, who built the distinctive-looking bridges for Gretsch in his own workshop. The Synchro-Sonic’s elaborate design is described in 50 Years of Gretsch Electrics as a “complex mass of chrome-plated metal that looks like it might be more at home on a saxophone.” Nonetheless, the book continues, “Gretsch immediately realized the Melita’s potential to provide the more accurate intonation that was required on electric guitars.”

Such accurate intonation is enabled by a sliding saddle for each string that can easily be moved forward and backward. Each saddle is topped by a thumbscrew that is easily loosened to allow saddle adjustment and then tightened to lock the saddle in place. No tools are required; all adjustment can be made using only the fingers. The Melita Synchro-Sonic bridge was largely superseded in the late 1950s by the simpler Space Control bridge (see below), but was revived in Gretsch’s modern era as a classic feature and remains in use today on several Falcon™, Country Club™, Jet™ and Penguin™ models.

“Rocking” Bar Bridge

Modern Gretsch Rocking Bar bridge.

Fixed solid-bar bridges were common on early Gretsch guitars; these were simple chrome-, nickel- or gold-plated brass bars seated on ebony or rosewood bases, with the entire assembly held in place only by string tension. There were no light-gauge electric guitar strings in the 1950s, and while the design straightforwardness of these bridges offered good sustain and tone, there was no means of adjusting individual string intonation (other than the entire bridge being positioned at an angle).

With impetus and input from Chet Atkins, Gretsch developed a new design for these bar bridges in the mid-1950s that featured cone-shaped postholes. This allowed the bar to smoothly rock back and forth on guitars fitted with Bigsby® vibrato tailpieces while still offering solid sustain and great tone. These “Rocking” Bar bridges became a hit with players and have been a Gretsch staple ever since.

While only a very few Gretsch guitar models use a vintage-style non-rocking bar bridge today (i.e., the G6120EC Eddie Cochran Tribute Hollow Body and G6120DSW Chet Atkins Hollow Body), the modern version of the Rocking Bar bridge is found on many contemporary Gretsch guitars—especially various Chet Atkins Country Gentleman®, 6120 Hollow Body, 6121 Solid Body and Tennessee Rose™ models.

Space Control™ Bridge

Modern Gretsch Space-Control bridge.

Gretsch devised the Space Control bridge, so named for its method of adjusting the spacing between each string, in 1957. Gretsch had started making its own pickups by that year, and followed suit by beginning to make its own bridges in-house, too, as opposed to the original Synchro-Sonic bridges that Johnny Melita had been producing for Gretsch in his own workshop.

As noted in 50 Years of Gretsch Electrics, this would allow Gretsch to “dispense with Mr. Melita’s services … and thereby gain more control over the production and supply of key components.”

Designed by Gretsch’s own Jimmie Webster, the Space Control bridge was far simpler than the earlier Melita bridge, although it didn’t offer individual string intonation. What it did offer was simple adjustment of the spacing between each string, by means of six wheel-shaped saddles positioned along a threaded bar. This lets the player set a broad string spread for finger-style work or a narrow spread for pick and chord work. The Space Control bridge started replacing the Melita bridges in 1957 and remains a classic feature in the modern Gretsch era, appearing on several Gretsch Falcon, Country Club, Jet, Penguin, artist and bass guitar models.

Adjusto-Matic™ Bridge

Modern Gretsch Adjusto-Matic bridge.

The most commonplace modern Gretsch guitar bridge is undoubtedly the Adjusto-Matic bridge, which appears on roughly half the models in the current Gretsch electric instrument lineup.

Introduced in the early 1970s as the “Adjustamatic” bridge, it offered precise individual intonation for each string by means of six individually adjustable saddles. The design was considerably more modern and streamlined than the previous Gretsch bridge to offer individual string intonation, the Melita Synchro-Sonic of 20 years earlier, although, as with most electric guitar bridges, tools were required for fine-tuning with an Adjustamatic bridge. There’s also an element of the Rocking Bar bridge at work too, as the Adjustamatic—known today in its improved version as the “Adjusto-Matic” bridge—slightly rocks back and forth when used with a Bigsby vibrato, reducing friction and adding tuning stability.
