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
Jack White's 2025 No Name Tour features live tracks from his album No Name, with shows across North America, Europe, the UK, and Japan.
The EP is a 5-song collection of live tracks taken from White’s 2024 edition of the tour, which was characterized by surprise shows in historic clubs around the world to support the 2024 album No Name.
No Name is available now via Third Man Records. The acclaimed collection was recently honored with a 2025 GRAMMY® Award nomination for “Best Rock Album” – White’s 34th solo career nomination and 46th overall along with 16 total GRAMMY® Award wins. The No Name Tour began, February 6, with a sold-out show at Toronto, ON’s HISTORY and then travels North America, Europe, the United Kingdom, and Japan through late May. For complete details and remaining ticket availability, please visit jackwhiteiii.com/tour-dates.
White’s sixth studio album, No Name officially arrived on Friday, August 2 following its clandestine white-label appearance at Third Man Records locations that saw customers slipped, guerilla-style, free unmarked vinyl copies in their shopping bags. True to his DIY roots, the record was recorded at White’s Third Man Studio throughout 2023 and 2024, pressed to vinyl at Third Man Pressing, and released by Third Man Records.

Solodallas SVDS Boost
solodallas.com
The Schaeffer-Vega Diversity System—an early and very successful wireless system—excelled at the tasks it was designed for. But there was more magic than met the eye. Though designed to sound as transparent as possible, it nonetheless colored the signal in a way that people like Angus Young and Eddie Van Halen found essential.
SoloDallas explored the possibilities of this circuit before in pedals like theSchaeffer Replica, but the new SVDS Boost strips the formula to essentials. Minimalist controls—one knob, that’s it—make this boost no less delicious. I’m not surprised Angus Young was smitten with the original SVDS. An SG and Marshall 18-watt amp sound fantastic naked, but the SVDS Boost has the rare talent for fattening everything without seeming to favor or obscure any frequency band too much. And as zest to the PAF/Marshall style formula, it makes the kind of rowdy, organic, airy, large, and punch-packing Marshall sound you would dream of getting in a studio or hearing on the radio. There are many shades of this basic awesome color in spite of the single knob. Unity gain lives in the earliest third of its range. From there you certainly get more volume, but mostly you bathe in various hues of compressed, saturated, thick, and dynamite growl. You don’t need a Gibson and a Marshall to use it to devastating effect, either. A Telecaster and Vibrolux snap with attitude and whip-crack energy with the SVDS in the line. And with both guitar/amp combos, the SVDS’ wide dynamic responsiveness to volume and tone attenuation assures that things stay cracking when you need more control.
Learn about this iconic guitar's journey, its mods done by Frank, and hear how it sounds in the hands of his son Dweezil.
Neil Young’s ’70s hits are some of the most recognizable radio rock jams of all time. But Neil’s guitar playing continued to grow over the ensuing decades, as he traversed styles from blues to country to electronic to rockabilly and beyond, eventually developing one of the most tonally decadent, fully formed improvisational voices in the entire guitar universe.
