Testing materials is the foundation of any scientifically based build. Here, an FFT analyzer is used to track sonic response.
When I first took my stab at lutherie, I mostly did maintenance work. Fret work, bone nuts and saddles, and basic setups made up the bulk of my daily agenda. I was exposed to many great guitars, both acoustic and electric. And even though I played electrics out on the gig, my primary interest was always acoustic guitars. I was just obsessed with figuring out what made them tick. Once I moved into instrument making, I found it difficult to produce the concert-level quality instruments I had become so accustomed to in my repair days. I was inspired to take a more analytic approach to instrument making, which was ultimately an attempt to tighten-up the consistency, tone, and overall playing experience for my customers.
The science of instrument making is an extraordinarily interesting world. My studies began with basic data collecting, such as material strength and weights, until I eventually developed a spreadsheet to better track my builds and improve the sound quality of my guitars. Eventually, this approach introduced me to a whole culture of scientists and engineers that were pursuing the same passion, and they were very open to the exchange of information. This solidified my commitment to the field of voicing science, and vastly improved the quality of my instruments.
What we are experiencing today is an explosion in the study of sound. This is a revolution that has been decades in the making.
Over time, these methods have picked up steam, with most of today’s hand-builders adopting some level of voicing science to improve the outcome of their instruments. In the end, all of this is an attempt to unlock the methods of the finest luthiers, such as the violin makers building in the European tradition, makers such as Lloyd Loar, or even the Martin Guitar Company’s contributions from the mid-to-late 1930s.
But what we are experiencing today is an explosion in the study of sound. This is a revolution that has been decades in the making. My first exposure was in the ’90s when I met a classical guitar maker by the name of Richard Schneider, who worked alongside a physical chemist named Michael Kasha, who was not a luthier himself. Together, they teamed up and made many advancements in the science of sound. Another major push was the book Left-Brain Lutherie written by David C. Hurd, Ph.D. This is a great think-book that put most modern luthiers on the path of analytical guitar making. In our shop, this book was on the bench constantly, as it helped us maneuver through many tough questions about instrument acoustics. Most recently, Australian luthier Trevor Gore published Contemporary Acoustic Guitar Design and Build, which has been a go-to for most modern luthiers. Trevor is a talented builder, and his contributions will inspire many others to come.
Precision building is crucial for the best, most harmonically rich tops.
But what does this mean to you, the player? This is the question. In the early ’90s, us builders noticed a major improvement in the quality of builds in the micro-building market. This was mostly due to groups such as the Guild of American Luthiers and the Healdsburg Guitar Festival. These groups offered a platform for guitar makers to compare notes, and this information exchange vastly improved the qualities of their builds. About five years after that, we all noticed everyone’s building style and finish went through a major transformation. This illustrates why the dawn of voicing science is so important—the exchange of science and information improves instrument quality for everyone. This is what is happening now. All the serious makers are currently implementing techniques set into motion by the research of the past 40 years and are sharing their findings with the world.
These days, I am noticing a major improvement in the tone and the stability of acoustic instruments. One builder who stands out in my mind is Colorado luthier Michael Bashkin, whose OM classical guitar is a major play for tonal excellence. So, for you the guitar buyer, this is a very good time to be shopping around the custom-guitar market. There is no doubt we are experiencing the next level in guitar making. And it will only get better.

Duane Betts enjoys a control set modification that was preferred by his father, the late, legendary Dickey Betts.

Betts’ 1961 ES-335 has its toggle and volume-dial positions switched.
A: My favorite mod is the one on my 1961 Gibson ES-335. The toggle switch and neck volume knob positions have been switched so the volume knob is more accessible for volume swells using your pinky finger. This is something my dad had done when he obtained the guitar in the ’90s as he loved using the volume swell effect.
A pedal primed for vintage fuzz sounds.
Obsession: My current obsession is this DanDrive Secret Machine fuzz that JD Simo gave me a few years ago. I don’t use fuzz often but I’ve loved it as a way to change things up and give the listener something fresh. My normal tone is very natural with the amp turned up. This is just a great fuzz tone that gives me a new angle that I really enjoy pursuing both live and in the studio.

A: A push/pull knob for humbucker coil split. It’s a sneaky little mod I throw on my tone pots. You won’t get amazing Strat tone, but the ability to instantly swap between Les Paul chunk and Fender twang during a jam opens a ton of possibilities tonally. Plus, no extra switches or routing needed—even though it’s fun to hack guitars apart.
Obsession: The EVH 5150 Iconic EL34 amp. Owning an 80-watt half-stack in a Brooklyn apartment might be overkill, but damn this amp is awesome. It delivers insane amounts of gain and distortion, yet every little nuance of your playing comes through crystal clear. I pair it with a Bugera Power Soak so I can crank the head and get that warm “Brown Sound” tone at lower volumes.

John Bohlinger and his Lukather-ized Strat.
A: I’ve hacked up a bunch of guitars over the years, but my favorite mod remains the highly intrusive, expensive, and quixotic B-bender install. It is the equivalent of open heart surgery, and there’s no going back—but the first time you play the Clarence White “You Ain’t Goin’ Nowhere” intro right, it’s totally worth it.
John at work. When it comes to mods, he know the drill!
Obsession: I recently filmed a PG video where we swapped pickups in my ’90s Strat with an EMG Lukather set. I never thought I’d go active, but what gets me is how smoothly the volume and tone work. I’m rethinking all my gear biases. Like maybe there’s been some progress since 1957.

Let it bleed: Jon dials back the treble on his Tele.
A: Installing a treble bleed on my volume pots has changed how I play electric guitar. Previously, I never dialed back my volume knob because it dulled my sound. Now I can fine-tune loudness and gain while retaining tone—it’s a game changer. I still swap pickups and hardware, but one mod always comes first: the humble treble bleed.
Did you know both John Paul Jones and Jimmy Page played on Shirley Bassey’s iconic recording of “Goldfinger?”
Obsession: John Paul Jones. I’ve always loved his bass (and other instrumental contributions) with Led Zeppelin. But after seeing the Zep documentary [Becoming Led Zeppelin] I searched his session work from 1964–1968, which includes Shirley Bassey, Lulu, Donovan and more. What an amazingly versatile and talented artist he is!
“I am thrilled to announce the launch of The Collection: Kirk Hammett. I’ve worked diligently on this curated collection of vintage and modern guitars for the book. I feel the book captures the rich history and artistry behind each of these unique and rare instruments. Every picture tells a story and thanks to Ross Halfin and his exceptional photography, every picture in this book is worth a million words! This book could not be possible without the help of Gibson, so I’d like to thank them for making my passion for Greeny, and guitars a reality. I hope all of you enjoy this journey as much as I did.”
“It’s exciting the time has come to release The Collection: Kirk Hammett by Gibson,” adds Cesar Gueikian, President and CEO of Gibson. “We have been working on this project with Kirk for years now, and I had the opportunity to work closely with Kirk on the composition of the collection for the book. It was a thrill to put this together and it took a village to get it done! I hope everyone appreciates the work that went into this book and enjoys every story behind the guitars.”
