Esoterica Electrica columnist and luthier Jol Dantzig has been exploring string-tension myths in recent Premier Guitar articles. Here are some thoughts to add to the discourse.
Dear Jol Dantzig,
Your recent PG articles, "The Doors of Perception" and the follow-up "The String-Tension Follies Experiment, Continued," are an interesting read about string tension, a topic of which your friend Collin Olson of D'Addario said: "There's definitely a lot of confusion out there." He's right, and you're definitely not alone with your doubts, thoughts, and struggles.
Recently a bass builder came up with the idea of how to make a 30" short-scale feel and sound like a 34" long-scale bass. He intended to use a string-through bridge and attach the tailpiece at a place where Floyd-Rose-equipped guitars have those spring-claws to elongate string length. He was about to spend a lot of money on a patent, which he now hopefully saves for something else.
I've discussed this topic in a few earlier columns, but sometimes we might be skeptical about a certain idea and need a different explanation and view angle before we know what's wrong. And since this is even discussed among experienced luthiers, I wanted to shed some light on it.
You mentioned four questions you've been thinking about, and I allow myself to start with my short answers:
1. Does overall string length affect tension?
No.
2. Does string tension really affect tone?
No and yes.
3. Is sustain hampered by pickup magnets?
Yes.
4. Can Eric Johnson tell when my battery is alkaline?
Surely not, but he's free to believe whatever he wants.
With questions #3 and #4 being a very different topic, let's focus on questions #1 and #2.
The issue of string tension has a mathematical answer. This is the formula for a string's tension (T):
Uw= specific weight per length unit of core and winding, L= scale length, f= frequency.
I'm sure you've seen this, but let's put it in words: For a given speaking length of a specific string, tension equals frequency, or the root thereof.
And, less mathematical, if I said that length behind the bridge would add tension, you'd need to tune down to a lesser tension to get back to pitch "f." A classic circulus vitiosus.
Tension (if one-dimensional) is an axial force between two points and is in equilibrium across the whole length of the string between both anchor points, wherever these are. But pitch only depends on its speaking length.
I've discussed this topic in a few earlier columns, but sometimes we might be skeptical about a certain idea and need a different explanation and view angle before we know what's wrong.
Question #2 is a bit more complicated because I think the question should be: Does overall string length affect tone? While tension doesn't affect tone, overall string length can. It's often said that additional string length adds especially to the low end, which once led to the idea of so-called bass-extenders (see "The B-String Extender Myth" [March 2013]).
Two of these "bass-extender" constructions are shown in Photo 1, which to me is not only simple, but debunking at the same time. In physics, it's often helpful to look at the extremes. Assuming adding length worked:
A.) It would be almost impossible to build a good-sounding headless bass, as these sport an extremely short overall string-length.
B.) Using an extra, extra-long string, wound all across the room, would allow one to forever dominate the bass world.
Both outcomes not only sound very unlikely but have been disproven. It's no surprise that you mention two specific instruments that led to the idea of outer string length affecting tension: the upright bass and an archtop guitar or bass.

Both of these are known for their extended string length behind the bridge, sport a separate bridge and tailpiece, and, more importantly, are half or fully acoustic instruments. On an acoustic instrument, you'll want to remove as much weight and stress from the soundboard. The first eases movement of the top, while the latter allows for an even thinner soundboard, moving even more air.
This construction with a very distant bridge and tailpiece is exactly the one where perception chimes in, although I'd prefer to use the term elasticity. Whenever we pluck or bend a string, we apply a force (F) to a given string with an elasticity (E) and diameter (A). According to Hooke's law for a material's elastic behavior:
E and A are constant and so would be the force that needs to be applied for bending a string by ∂l. For a given instrument, l0 is constant—close to the scale length for a headless, and scale length plus the additional length outside the scale, if the string can slip over the bridge once we bend it. When l0 getting bigger, the force needed for the same bend gets smaller and this results in the perception of a softer, more elastic string. Of course, the break angle at both ends of the scale length needs to be rather shallow with low friction to allow for the string's slippage (Photo 2). It's discussed in my PG column "The Break Dance Behind the Bridge" [February 2021].
A final answer to your question about its effect on tone is pretty complex and one I'm also still struggling with. A few of my thoughts on the subject went into the article "Bridge vs. Tone" [March 2021].
Maybe these can give you some ideas to chew on?
Sincerely,
Heiko PG

Milkman’s Jerry Garcia-style JG-40 combo.
Grateful Dead-inspired gear from Milkman and Scarlet Fire helps to keep the guitarist’s sound alive.
Guitar players wanting to catch the Grateful Dead’s particular lightning in a bottle exist along a spectrum. Some are content to take inspiration from Jerry Garcia’s playing but make their own way regarding guitar choice and signal path. Others strive to emulate Garcia’s sonic decisions down to the most minor details and create signal paths as close to Jerry’s as possible. In recent years, an ecosystem of gear has developed around fostering Jerry Garcia’s electric tone, including everything from guitars, amps, and stompboxes to on-board preamps and speakers.
Entire books about the Grateful Dead’s gear have been written, so we can’t cover it all here. Garcia tinkered with all facets of his sound from about 1971 until 1978, when his signal path reached stability. By then, his On-Board Effects Loop—an innovation he developed to control how much signal reached his effects—was dialed in, his backline firm, and his choice of effects pedals solidified. Even then, adjustments were made, especially when MIDI arrived or when technology like in-ear monitoring was used. Here are some basics.
Scarlet Fire’s recreation of Garcia’s Wolf, originally built by Doug Irwin.
It starts with guitars. For players wanting to get their Jerry on, there’s a wide range of Garcia-esque instruments—with just as wide a range of prices—out there. Recreations of the Doug Irwin guitars and the Fender Alligator Strat abound. China-built models from companies likePhred Instruments can go for as little as $700 or so. Luthier Thomas Lieber apprenticed with Irwin long ago, and his Lieber Guitars will deliver a copy of a variety of Garcia models. Leo Elliott’sScarlet Fire Guitars out of Dallas, Texas, takes things in another direction. Elliott builds Doug Irwin replicas that start at $20,000 and go up from there, with a current wait time of about 18 months for an instrument. He’s outfitted many of the top Garcia guitarists today, including Tom Hamilton Jr. and Jeff Mattson. Elliott says, “I’m a self-taught luthier; I didn’t really build my first guitar until 2010. I understood a little bit about woodworking before I got started, but I learned by reading books and through trial and error. I started building replicas of Doug Irwin’s Wolf guitar right away, which is sort of like building a car and starting with a Ferrari. I didn’t know any better. Then, eventually I got to know Doug Irwin and collaborated with him. So, I got to hold Garcia’s Tiger guitar and get to know it really well, and by 2015, I had built replicas of that guitar. There’s one guy who helps me around the shop, but otherwise, I am building these guitars on my own. I’m collaborating with Doug Irwin on a new series of Tiger guitars, which will retail for 50 grand each.” That’s one way to get your Jerry going.
The JBL-inspired Milkman K-120.
Garcia’s choice of amplifiers is another matter. He preferred Fender Twin Reverbs loaded with JBL Alnico speakers, which were popular amongst many rock bands in the 1970s. The details get complicated; Garcia’s amps were heavily modified, and the Fender Twin served as a preamp that ran to a McIntosh MC-3500 power amp.
It’s hard to find vintage JBL speakers today—at least ones in good shape. San Francisco’s Milkman Sound, founded by Tim Marcus, has created a faithful reproduction of those classic JBLsthey call the K-120. They’re coupling those speakers with a Garcia-style recreation of his Fender Twin that Marcus named the JG-40. “I think 75 percent of Jerry’s tone is in the JBL speakers,” Milkman’s founder says. “But when you start to analyze the other 25 percent, you kind of have to start withDon Rich. [Editor’s Note: Rich was the guitar player in Buck Owens’ band, pioneers of the Bakersfield Sound.] That’s Jerry’s tone, too, but the difference is Garcia’s midrange was a bit throatier. It sounds clean, but really, it’s not clean at the same time. Especially his tone in the late ’70s. There is something about running that Fender Twin Reverb through the McIntosh that would just completely blow out the tone in a really interesting way.”
Garcia colored his tone with off-the-shelf effects. This was, after all, long before the days of boutique pedals. By 1978 and beyond, you’d hear him playing through an MXR Distortion+, an MXR Analog Delay, and an MXR Phase 100. He often used auto wahs, preferring the Musitronics Mu-Tron envelope filter as well as a Mu-Tron Octave Divider and a Mu-Tron combination volume and wah pedal.
When I asked Jeff Mattson, Bella Rayne, and Tom Hamilton Jr. exactly how orthodox they are about using the kind of gear that Garcia did, I got three different answers.
Mattson tells me that because Dark Star Orchestra is doing something very specific, he really has to tailor his sound as carefully to Garcia’s as he can. “Some folks get too hung up on small things, like what kind of cable to use and things like that, and I don’t go that far. But it’s important for Dark Star Orchestra to get Jerry’s sound right because we are covering different eras and different shows. In 2022, for example, we went to Europe and recreated shows from the Dead’s famous Europe ’72 tour, so you have to pay close attention to what kind of gear they were using to do that right.”
Hamilton works differently. He’s always preferred a higher-gain signal than Garcia ever did, landing in more of a British or heavy metal tone. (Randy Rhoads was a big influence.) “I’ve always approached it like, ‘What’s the new information we can put into this thing?’” he says. “Not just recreate but pushing in a forward direction. And anytime I’ve played with the guys who played with Garcia back in the day, they always said to me, ‘You’re here because you’re here. Don’t try and do what we did back in 1978 or do it because Garcia did it that way.’ They’ve always encouraged me to be myself.”
Bella Rayne is just wrapping her head around what it really means to try to sound like Garcia. “Besides Jerry, I’m influenced by guitarists like Dickey Betts and Derek Trucks, so my tone tends to be a bit heavier and bluesy,” she explains. “I’m generally running a Stratocaster through a Fender Twin Reverb. But recently, I was doing a show, and a buddy of mine set up a Jerry rig for me, and that was so cool: JBL speakers, McIntosh head, the whole setup. I had never played through one. I didn’t know what the hype was all about. I plugged in, and it was just amazing; there was such a snap, and I was really commanding the band. I can see myself keeping my current rig but adding a Dead-rig to experiment. But honestly, anything is fine; I am not picky. I just want to play the best that I can.”
Brent Mason is, of course, on of the most recorded guitarists in history, who helped define the sound of most ’90s country superstars. So, whether you know it or not, you’ve likely heard Mason’s playing.
Professional transcriber Levi Clay has done the deepest of dives into Brent Mason’s hotshot licks. At one point, he undertook the massive project of transcribing and sharing one of Mason’s solos every day for 85 or so days. Mason is, of course, on of the most recorded guitarists in history, who helped define the sound of most ’90s country superstars. So, whether you know it or not, you’ve likely heard Mason’s playing. Levi shares the insight he gleaned from digging deep, and he tells us what it was like when they shared a stage last year. Plus, Levi plays us some great examples of Mason’s playing.
