Galloup’s Plek tech Adam Winarski preps a Yamaha acoustic for the machine.
Presently, many certified guitar-repair specialists possess the expertise required to deliver an instrument that both sounds and plays wonderfully. The standards set by manufacturers and distributors have significantly risen, safeguarded by rigorous quality protocols to guarantee the best possible acoustic experience for customers. Additionally, lutherie training has raised the bar for critical processes, and one of the most tricky is fretwork.
Traditional fretwork once involved manual labor, with technicians utilizing sandbags or similar supports to steady the neck as they straightened it with a truss rod during the filing process. A notable advancement in this field came in the mid 1970s when Don Teeter, an author and repair expert, imposed a new method: fixing the guitar body to the bench and using blocks to maintain the neck in a playing position. This refinement was one of many in the continued quest to produce superior instruments by standardized methods.

In the late 1970s, another pivotal innovation was introduced by Dan Erlewine. He created an advanced fret jig with a specialized body-holding system and neck supports, adding another layer of precision to the repair process. During my collaboration with Dan in 1985, we developed a rotating neck jig that counterbalanced the forces of gravity, keeping the instrument in its playing orientation while adjusting the neck supports. This step represented a significant leap in establishing control and standardization of fretwork procedures in our industry. By 1986, our approach had evolved into a freestanding workstation coupled with a sophisticated hold-down mechanism and enhanced neck supports, culminating in increased accuracy, efficiency, and consistency. Over the decades, the Erlewine/Galloup rotating neck jig has become a benchmark in numerous shops, enhancing fretwork performance.

By the 1990s, automated and computerized technologies permeated the guitar manufacturing and repair sectors. Initially applied by import companies in the mass production of guitars, the technology, although expediting processes, did not immediately achieve high execution standards. However, the tech dramatically improved over time, with computer-driven systems eventually transforming the industry. Contemporary automated production utilizing such advancements meets exceedingly high standards of precision. Some bespoke guitar manufacturers, such as Steve Andersen, were pioneers in adopting these methods, but it was companies like Taylor that established them in the modern era.
Inevitably, the progression of technology extended beyond the mere production of parts. Around 1995, German engineer Gerd Anke envisioned the integration of computer-assisted technology into enhancing instrument playability, giving rise to Plek technology, which uses computers to precisely measure and analyze the various components of a guitar, like neck relief, fret height, nut and bridge specs, and more. Nashville guitar-repair tech Joe Glaser was among the first to recognize the machine’s value, followed by San Francisco luthier Gary Brawer. When Heritage Guitar Inc. invested in a Plek machine, the guitar industry could no longer disregard the significance of this innovation.
“The machine’s scanning data confirmed that there was one nature of an ideal fret plane, done by hand or machine, and unsurprisingly, it conformed exactly to what physics predicts, not personal mojo.”
In the spring of 2022, Galloup Guitars obtained its first Plek machine. Promptly, our technician Adam Winarski paved the way for the Plek’s integration in our shop. Now, it’s a rarity for an instrument to leave our shop without having undergone Plek analysis and machining. Impressed by the results of our integration, we created “Intro to Plek” as a course for all students enrolled at the Galloup School of Lutherie, offering our students a practical introduction to this technology. We furthered this educational initiative with a comprehensive one-week intensive “Plek Certification Training Course” for both students and the public. This advanced Plek course serves those seeking to boost their knowledge base and employability in this high-precision field.
Plek is rapidly becoming an industry standard for major manufacturers and smaller shops alike. However, this does not mean that those without access to this technology cannot execute proficient fretwork. Personally, I continue to use my Erlewine/Galloup neck jig—not only out of nostalgia, but also because it remains an excellent method for delivering accurate and reliable guitars. Still, it’s undeniable that the process of fretting, fret dressing, and analytics of fretted instruments has undergone significant transformation, resulting in better sounding—and playing—guitars. And ultimately, that’s what it’s all about.
Gibson originally launched the EB-6 model with the intention of serving consumers looking for a “tic-tac” bass sound.
The Gibson EB-6 was announced in 1959 and came into the world in 1960, not with a dual-horn body but with that of an elegant ES-335. They looked stately, with a thin, semi-hollow body, f-holes, and a sunburst finish. Our pick for this Vintage Vault column is one such first-year model, in about as original condition as you’re able to find today. “Why?” you may be asking. Well, read on....
When the EB-6 was introduced, the Bass VI was still a glimmer in Leo Fender’s eye. The real competition were the Danelectro 6-string basses that seemed to have popped up out of nowhere and were suddenly being used on lots of hit records by the likes of Elvis, Patsy Cline, and other household names. Danos like the UB-2 (introduced in ’56), the Longhorn 4623 (’58), and the Shorthorn 3612 (’58) were the earliest attempts any company made at a 6-string bass in this style: not quite a standard electric bass, not quite a guitar, nor, for that matter, quite like a baritone guitar.
The only change this vintage EB-6 features is a replacement set of Kluson tuners.

Gibson, Fender, and others during this era would in fact call these basses “baritone guitars,” to add to our confusion today. But these vintage “baritones” were all tuned one octave below a standard guitar, with scale lengths around 30", while most modern baritones are tuned B-to-B or A-to-A and have scale lengths between 26" and 30".)
At the time, those Danelectros were instrumental to what was called the “tic-tac” bass sound of Nashville records produced by Chet Atkins, or the “click-bass” tones made out west by producer Lee Hazlewood. Gibson wanted something for this market, and the EB-6 was born.
“When the EB-6 was introduced, the Bass VI was still a glimmer in Leo Fender’s eye.”
The 30.5" scale 1960 EB-6 has a single humbucking pickup, a volume knob, a tone knob, and a small, push-button “Tone Selector Switch” that engages a treble circuit for an instant tic-tac sound. (Without engaging that switch, you get a bass-heavy tone so deep that cowboy chords will sound like a muddy mess.)
The EB-6, for better or for worse, did not unseat the Danelectros, and a November 1959 price list from Gibson hints at why: The EB-6 retailed for $340, compared to Dano price tags that ranged from $85 to $150. Only a few dozen EB-6 basses were shipped in 1960, and only 67 total are known to have been built before Gibson changed the shape to the SG style in 1962.
Most players who come across an EB-6 today think it was a response to the Fender Bass VI, but the former actually beat the latter to the market by a full year.

It’s sad that so few were built. Sure, it was a high-end model made to achieve the novelty tic-tac sound of cheaper instruments, but in its full-voiced glory, the EB-6 has a huge potential of tones. It would sound great in our contemporary guitar era where more players are exploring baritone ranges, and where so many people got back into the Bass VI after seeing the Beatles play one in the 2021 documentary, Get Back.
It’s sadder, still, how many original-era EB-6s have been parted out in the decades since. Remember earlier when I wrote that our Vintage Vaultpick was about as original as you could find? That’s because the model’s single humbucker is a PAF, its Kluson tuners are double-line, and its knobs are identical to those on Les Paul ’Bursts. So as people repaired broken ’Bursts, converted other LPs to ’Bursts, or otherwise sought to give other Gibsons a “Golden Era” sound and look ... they often stripped these forgotten EB-6 basses for parts.
This original EB-6 is up for sale now from Reverb seller Emerald City Guitars for a $16,950 asking price at the time of writing. The only thing that isn’t original about it is a replacement set of Kluson tuners, not because its originals were stolen but just to help preserve them. (They will be included in the case.)
With so few surviving 335-style EB-6 basses, Reverb doesn’t have a ton of sales data to compare prices to. Ten years ago, a lucky buyer found a nearly original 1960 EB-6 for about $7,000. But Emerald City’s $16,950 asking price is closer to more recent examples and asking prices.
