What started in Sacha Dunable's two-car garage has now expanded to include a dozen riff maniacs building impeccable riff machines. Join PG's Chris Kies to go inside these guitar junkies' L.A.-based shop.
Dig into this inside view of the Dunable guitars shop in Los Angeles, conducted by PG’s own Chris Kies and namesake builder Sacha Dunable. It’s a major step up from the two-car garage where the company started in 2012! Dunable grew from making one-off guitars for Sacha and his fellow Intronaut guitarist, Dave Timnick, by generating word-of-mouth about the instrument’s easy playability and biting rock tone. “Before I know it, I was getting orders for guitars,” Dunable says.
Our tour starts in the tonewood storage room: mahogany, limba, maple—mahogany primarily for guitar necks and maple primarily for bass necks. Fretboards are ebony. For bodies, it’s mahogany, limba, and swamp ash. Watch a run of bodies for Dunable’s Gnarwhal model in the saw shop (check out the stunning buckeye burl wood for tops) and eyeball the varieties of raw ebony for fretboards. In the CNC shop, you’ll see how to design a custom guitar and then observe one of Dunable’s two CNC machines in operation. “It’s about the consistency, not the speed,” Dunable assures.
Also, you’ll see that all the final cut and trim work is done by hand, as is the artful sanding. (You’ll eyeball a Yeti being smoothed.) In the neck area, Dunable explains the various scale lengths on the company’s instruments, and how some of their production-run necks are farmed out to Grover Jackson’s Tennessee shop. Frets? Dunable’s come from respected fret-wire company Jescar, and they’re typically nickel extra jumbos. After the necks are glued in place, it’s time for paint prep: removing minor blemishes, etc. A gel wood sealer is part of Dunable’s finishing process, “so you can really feel the wood grain and hear the wood resonate,” Sacha explains. He displays a fresh black rainbow sparkle finish with nitro lacquer and a rose-gold over swamp ash, which really lets the wood grain show. Also, get a look at a beautifully finished Dunable Minotaur, plus a rare 9-string Yeti (with doubled treble strings).
In the assembly shop, it’s time to check out Dunable’s own pickups. They’re double-wax-potted by hand (unless requested otherwise). Some Cave Bear pickups are displayed—the latest in the company’s 10-humbucker line. And the last step is final assembly for Dunable’s roughly 50 guitars shipped per month, and includes custom setup if requested. As the video concludes, Dunable talks about his Southeast Asia-made, lower-priced DE Series, which are setup, tested, and quality checked at the L.A. shop before leaving for stores and individual owners.

Alongside Nicolas Jaar’s electronics, Harrington creates epic sagas of sound with a team of fine-tuned pedalboards.
Guitarist Dave Harrington concedes that while there are a few mile markers in the music that he and musician Nicolas Jaar create as Darkside, improvisation has been the rule from day one. The experimental electronic trio’s latest record, Nothing, which released in February on Matador, was the first to feature new percussionist Tlacael Esparza.
Taking the record on tour this year, Darkside stopped in at Nashville’s Brooklyn Bowl, where Harrington broke down his complex signal chains for PG’s Chris Kies.

Express Yourself
Harrington bought this mid-2000s Gibson SG at 30th Street Guitars in New York, a shop he used to visit as a kid. The headstock had already been broken and repaired, and Harrington switched the neck pickup to a Seymour Duncan model used by Derek Trucks. Harrington runs it with D’Addario NYXL .010s, which he prefers for their stretch and stability.
The standout feature is a round knob installed by his tech behind the bridge, which operates like an expression pedal for the Line 6 DL4. Harrington has extras on hand in case one breaks.
Triple Threat
Harrington’s backline setup in Nashville included two Fender Twin Reverbs and one Fender Hot Rod DeVille. He likes the reissue Fender amps for their reliability and clean headroom. Each amp handles an individual signal, including loops that Harrington creates and plays over; with each amp handling just one signal rather than one handling all loops and live playing, there’s less loss of definition and competition for frequency space.
Dave Harrington’s Pedalboards
Harrington says he never gives up on a pedal, which could explain why he’s got so many. You’re going to have to tune in to the full Rundown to get the proper scoop on how Harrington conducts his three-section orchestra of stomps, but at his feet, he runs a board with a Chase Bliss Habit, Mu-Tron Micro-Tron IV, Eventide PitchFactor, Eventide H90, Hologram Microcosm, Hologram Chroma Console, Walrus Monument, Chase Bliss Thermae, Chase Bliss Brothers AM, JHS NOTAKLÖN, two HexeFX reVOLVERs, and an Amped Innovations JJJ Special Harmonics Extender. A Strymon Ojai provides power.
At hip-level sits a board with a ZVEX Mastotron, Electro-Harmonix Cathedral, EHX Pitch Fork, Xotic EP Booster, two EHX 45000 multi-track looping recorders, Walrus Slöer, Expedition Electronics 60 Second Deluxe, and another Hologram Microcosm. A Live Wire Solutions ABY Box and MXR DC Brick are among the utility tools on deck.
Under that board rest Harrington’s beloved Line 6 DL4—his desert-island, must-have pedal—along with a controller for the EHX 45000, Boss FV-50H volume pedal, Dunlop expression pedal, Boss RT-20, a Radial ProD2, and another MXR DC Brick.

Our columnist’s collection of moon spruce, ready for inspection—with a view.
As players get older, our instrument needs change. Our columnist shares how he designed an acoustic adapted to arthritis.
For many acoustic guitarists, playing the instrument is one of life’s greatest joys. As a luthier, I’ve seen firsthand how deeply musicians cherish their guitars, something they look forward to playing not just weekly, but daily. As any guitarist knows, some guitars simply feel different. While some are more rigid and require extra effort to play, others feel smooth and effortless. With this in mind, as our playing needs evolve, so too may the instruments we choose to accompany us.
My clientele is diverse, ranging from musicians in their 20s to those well into their 70s and 80s. One common challenge I have observed is that as players reach their 50s, many begin experiencing arthritis, which can hinder their ability to play comfortably. There are several techniques luthiers use to improve playability, such as lowering the action or opting for a shorter scale length; for instance, switching from a Martin 25.4" scale to a Gibson 24.750" scale. But, over the years, I began considering whether it would be possible to design a guitar specifically for players with arthritis, allowing them to continue playing with less strain on their hands, shoulders, and overall body.
My guitars are already designed to be exceptionally easy to play. They are not built for aggressive strumming or rugged outdoor use, though I can accommodate various styles. Recently, I took this concept a step further for a customer, creating an instrument with a smaller neck. Moving away from the traditional 1.750" nut width, I refined it to a slender 1.675". The string spacing at the bridge was adjusted to 2 3/16" instead of the wider 2 1/4" spacing used primarily for fingerstyle playing. Additionally, I incorporated a 25" scale length for a lower string tension at full pitch.
Combined with a 13-frets-to-the-body design, these adjustments made the guitar feel significantly smaller and more comfortable in the player’s hands. To enhance comfort further, I used an orchestra-class instrument, and added both an arm and belly bevel, reducing strain on the player’s shoulders. Even though I chose an OM for this build, an auditorium-class design would work well, too.
However, the most crucial aspect of this instrument was the top, which serves as its engine. I selected a piece of moon spruce, personally sourced in Switzerland in August of last year. This type of spruce is lightweight and highly responsive. More importantly, when voiced and tuned correctly, it requires minimal effort to produce sound and it has a higher level of admittance.
“Any movement on the strings, whether by the picking hand or the fretting hand, requires significantly less effort than on a traditional guitar.”
Admittance is a crucial factor when evaluating any musical instrument, whether one you are building or considering for purchase. In guitars and tonewoods, admittance is the amount of sound that can be produced with a standard level of effort. If a piece of wood has a high level of damping, it will not produce sound efficiently when built into a guitar, resulting in an instrument that is less enjoyable to play. Conversely, if the wood exhibits an extremely low level of damping, the guitar may feel responsive and lively, but this does not necessarily indicate a well-balanced instrument. Damping must be carefully controlled, particularly in the soundboard, to achieve an ideal balance. A properly voiced guitar should provide excellent responsiveness, a full and resonant sound, and treble frequencies that are rich and warm rather than thin or overly sharp. Thus, when discussing these aspects of guitar construction and tonewood selection, the key term to remember is admittance. For this build I was looking for high admittance while retaining a deep, well-balanced tone.
For the player, this means that even with standard tuning at A440 and regardless of whether they choose light or medium strings, though light gauge is preferable, the guitar remains incredibly soft to play. Any movement on the strings, whether by the picking hand or the fretting hand, requires significantly less effort than on a traditional guitar. This is due to the top’s high flexibility and responsiveness, allowing for a soft touch while maintaining a respectable level of volume.
For those dealing with arthritis or other hand-related challenges, selecting a softer-playing guitar is essential. Shorter scale lengths can be beneficial, but having an instrument custom-built by a luthier who understands these considerations can make a significant difference. For my customers facing these issues, my goal is to ensure they can continue playing for as long as possible. I recognize how important the guitar is to their lives, and I want to help them keep playing without unnecessary discomfort. If you are experiencing difficulties, there are options available, and solutions worth exploring.
