Hello, and welcome back to Mod Garage. This month, we will have a closer look at an often overlooked part of our guitar signal chain: the guitar cable. We’ll work out what really counts and how your cable’s tonal imprint differs from your guitar’s tone-control function.
Today, the choice of guitar cables is better than it’s ever been, and you can choose between countless options regarding color, stability, plug style, length, diameter, bending strength, shielding, etc. A lot of companies offer high-quality cables in any imaginable configuration, and there are also cables promising special advantages for specific instruments or music styles, from rock to blues to jazz.
Appearance, stability, longevity, bending stiffness, and plug configuration are matters of personal preference, and every guitarist has their own philosophy here, which I think is a great thing. While one player likes standard black soft cables with two straight plugs, their buddy prefers red cables that are stiff as hell with two angled plugs, and another friend swears by see-through coiled cables with golden plugs.
“We often want to come as close as possible to sounding like our personal heroes, but we fail because we’re using the wrong cable for a passive guitar.”
Regarding reliability, all these parameters are important. Who wants a guitar cable making problems every time you are on stage or in the studio? There are also technical parameters like resistance, capacitance, transfer resistance on the plugs, and more. Without making it too technical, we can summarize that, sound-wise, the only important technical parameter for a passive guitar circuit is the capacitance of the cable. Sadly, this information is often missing in the manufacturer’s description of a guitar cable, and there’s another thing we have to keep in mind: Most manufacturers try to offer cables with the smallest possible capacitance so the guitar can be heard “unaltered” and with a “pure” tone. While these are honourable intentions, they are self-defeating when it comes to making a guitar sound right.
Let’s take a trip back to the past and see what cables players used. Until the early 1980s, no one really cared about guitar cables—players simply used whatever was available. In the ’60s and ’70s, you could see a lot of ultra-long coiled cables on stage with players like Clapton, Hendrix, May, Townshend, Santana, and Knopfler, to name just a few. They used whatever was available, plugged in, and played without thinking about it. Ritchie Blackmore, for example, was famous for notoriously using incredibly long cables on stage so he could walk around. Joe Walsh and many other famous players did the same. Many of us have these players’ trademark sounds in our heads, and we often want to come as close as possible to sounding like our personal heroes, but we fail because we’re using the wrong cable for a passive guitar. So what are we talking about, technically?
It’s important not to look at the guitar cable, with its electrical parameters, as a stand-alone device. The guitar cable has to be seen as part of the passive signal chain together with the pickups, the resistance of the guitar’s pots (usually 250k or 500k), the capacitance of the wires inside the guitar, and, of course, the input impedance of the amp, which is usually 1M. The interaction of all these in a passive system results in the resonance frequency of your pickups. If you change one of the parameters, you are also changing the resonance frequency.
”Ritchie Blackmore, for example, was famous for notoriously using incredibly long cables on stage so he could walk around.“
You all know the basic formulation: The longer the cable, the warmer the tone, with “warmer” meaning less high-end frequencies. While this is true, in a few moments you will see that this is only half the truth. Modern guitar cables are sporting a capacitance of around 100 pF each meter, which is very low and allows for long cable runs without killing all the top end. Some ultra-low-capacitance cables even measure down to only 60 pF each meter or less.
Now let’s have a look at guitar cables of the past. Here, capacitances of up to 400 pF or more each meter were the standard, especially on the famous coiled cables. See the difference? No wonder it’s hard to nail an old-school sound from the past, or that sometimes guitars sound too trebly (especially Telecasters), with our modern guitar cables. This logic only applies to our standard passive guitar circuits, like those in our Strats, Teles, Les Pauls, SGs, and most other iconic guitar models. Active guitars are a completely different ballpark. With a guitar cable, you can fine-tune your tone, and tame a shrill-sounding guitar.
“No problem,” some will say. “I simply use my passive tone control to compensate, and that’s it. Come on, capacitance is capacitance!” While this logic seems solid, in reality this reaction produces a different tone. “Why is this?” you will ask. Thankfully, it’s simple to explain. You might be familiar with the typical diagrams showing a coordinate system with "Gain/dB" on the Y-axis and "Frequency/kHz" on the X-axis. Additional cable capacitance will shift the resonance frequency on the X-axis, with possible differences of more than one octave depending on the cable. A cable with a higher capacitance will shift the resonance frequency towards the left and vice versa.

Now let’s see what happens if you use your standard passive tone control. If you close the tone control, the resonance frequency will be shifted downwards mostly on the Y-axis, losing the resonance peak, which means the high frequencies are gone. This is a completely different effect compared to the additional cable capacitance.

To summarize, we can say that with different cable capacitances, you can mimic a lot of different pickups by simply shifting the resonance frequency on the X-axis. This is something our passive tone control can’t do, and that’s exactly the difference you will have to keep in mind.
So, let’s see what can be done and where you can add additional cable capacitance to your system to simulate longer guitar cables.
1. On the cable itself
2. Inside the guitar
3. Externally
In next month’s follow-up to this column, we will talk about different capacitances and how you can add them to your signal chain with some easy-to-moderate modding, so stay tuned!
Until then ... keep on modding!

Vox’s Valvenergy Tone Sculptor
I spent a day workshopping ideas in my studio using just the Vox Valvenergy Smooth Impact compressor and Tone Sculptor EQ, and a dash of amp tremolo and reverb to taste. In the process, I produced more arresting sounds than I had heard from my guitars in many days. There were radical direct-to-desk-style Jimmy Page/Beatles distortion tones, sun-sized, cosmic electric 12-string, Bakersfield twang that could burn through crude, and many other sweet and nasty colors. Most decent EQ and compressor combinations can achieve variations on all those themes. But the Smooth Impact and Tone Sculptor also reveal interesting personalities in unexpected places.
The individuality and energy in the Vox Valvenergy pedals is attributable, in part, to the Nutube vacuum tube used in the circuit. Though it looks little like a vacuum tube as most guitarists know them, the thin, wafer-like Nutube is, in fact, a real vacuum tube like those used in fluorescent displays. Fluorescent display tubes have limitations. A maximum operating voltage of around 40 volts means they aren’t useful for bigger power tube applications like a 6L6, which has an operating voltage of about 400 volts. But it can work quite well as a preamp tube in concert with an op amp power section, which is how the Nutube is used in the new Valvenergy pedals, as well as older Vox products like the Vox MV50 and Superbeetle amps.
Valvenergy Tone Sculptor
When you think about “cinematic” effects, you likely imagine big reverb or modulation sounds that create a vivid picture and feeling of space or motion. But narrow, hyper-focused EQ profiles can evoke very different and equally powerful images. Radical EQ settings can add aggression, claustrophobic intimacy, and stark, explosive dark-and-light contrasts more evocative of Hitchcock’s Psycho than Ridley Scott’s Blade Runner.
Any of these moods can be summoned from the Valvenergy Tone Sculptor. Six sliders cut or boost 10 dB frequency bands spanning 100 Hz to 5.6 kHz. A seventh slider cuts or boosts the master output by 12 dB. This platter of options might not sound like much. But you can use these seven controls together to very specific ends.
“Radical EQ settings can add aggression, near-claustrophobic intimacy, and stark, explosive dark-and-light contrasts.”
For example, bumping the high-midrange and the master output produces narrow cocked-wah-like filter sounds with enough push to produce extra amp overdrive—effectively turning the Tone Sculptor into a buzzy, almost fuzz-like filter effect. But unlike a wah, you can carefully scoop high end or add a spoonful of bass to blunt harsh frequencies or give the tone a bit more weight. You can also broaden the palette of an amp/guitar pairing. I matched a particularly trebly Jazzmaster bridge pickup with a very hot and toppy Vox AC15-flavored amp for this test—a recipe that can be spiky on the best days. But with the Tone Sculptor in the line, I could utilize the same sharp, fuzzy, and filtered Mick Ronson wah tones while shaving some of the most piercing frequencies.
EQ pedals exist on many points along the cost spectrum. And at $219, the Tone Sculptor lives on the high side of the affordable range. Does it offer something less expensive models can’t deliver? Well, for one thing, I found it relatively quiet, which is nice whether you’re shaping toppy high-contrast effects or performing more surgical adjustments. And the sliders feel nuanced and nicely tapered rather than like a dull axe with a few basic frequency notches. But in many situations I also liked the color imparted by the circuit—generated, presumably, by the Nutube. “Color,” in audio terms, is a broad and subjective thing, and one should not necessarily expect the warm, tube-y glow of a vintage tube Pultec. Still, the Tone Sculptor has many forgiving, flattering qualities—typical of studio EQs—that enable fine tuning and experimentation with more radical and creative applications of the effect.
Valvenergy Smooth Impact
As with the Tone Sculptor, the Smooth Impact’s use of Nutube engenders certain expectations. It’s easy to surmise that because Smooth Impact has a vacuum tube in the circuit that it will behave like a little Teletronix LA-2A leveling amplifier. That’s a big ask for a $219 stompbox. On the other hand, the Smooth Impact exhibits some appealing characteristics of studio tube compression. At lower compression levels, it works well as a thickening agent—adding mass without much additional noise. And at higher compression levels it can sound snappy, crisp, and tight without feeling like you’ve bled every trace of overtone from your signal.
The Smooth Impact’s controls aren’t totally atypical. But because it lacks some familiar features like variable attack and release, yet is more complicated than a 1-knob DynaComp, you have to trust your ear to navigate interactions among the controls. The most unfamiliar of these is the 3-way vintage/natural/sag toggle. The first two are defined by preset attack and release settings: Vintage is slow attack and long release, and natural is the opposite. The sag mode’s compression is more like what you get from tube saturation, and it’s useful for adding thickness and complexity to a thin amp tone at modest compression levels.
Though the vintage and natural modes certainly have a different feel, they don’t always sound worlds apart. And like the sag mode, the thing they have in common is the way they enrich lifeless amp output at low to medium compression, with a bit of grind from the tube gain and a little extra makeup gain from the output. At the most aggressive settings, the tube gain can get a little crispy. And really crushing the compression can flatline your tone without adding much in the way of extra sustain. These are limitations common to many compressors with similar features. But unless I was chasing very ultra-snappy Prince and Nile Rodgers fast-funk caricatures, I enjoyed the Smooth Impact most in its in-between ranges, where mass, mild, harmonious drive, and low noise showcase the pedal’s sometimes studio-like personality.
Boss’ firstWaza Tube Amp Expander, built with an integrated power amp that enables boosted signal as well as attenuated sounds, was and remains the OX’s main competition. Both products have copious merits but, at $1,299 (Boss) and $1,499 (Universal Audio), each is expensive. And while both units are relatively compact, they aren’t gear most folks casually toss in a backpack on the way out the door. The new Waza Tube Expander Core, however, just might be. And though it sacrifices some refinements for smaller size, its much-more accessible price and strong, streamlined fundamental capabilities make it a load-box alternative that could sway skeptics.
Micro Manager
The TAE Core is around 7 1/2" wide, just over 7 " long, and fewer than 4 " tall, including the rubber feet. That’s about half the width of an original TAE or OX. The practical upside of this size reduction is obvious and will probably compel a lot of players to use the unit in situations in which they’d leave a full-size TAE at home. The streamlined design is another source of comfort. With just five knobs on its face, the TAE Core has fewer controls and is easier to use than many stompboxes. In fact, the most complicated part of integrating the TAE Core to your rig might be downloading the necessary drivers and related apps.
Connectivity is straightforward, though there are some limitations. You can use TAE Core wirelessly with an iOS or Windows tablet or smartphone, as long as you have the BT-DUAL adaptor (which is not included and sets you back around 40 bucks). However, while desktop computers recognize the TAE Core as a Bluetooth-enabled device, you cannot use the unit wirelessly with those machines. Instead, you have to connect the TAE Core via USB. In a perfectly ordered world, that’s not a big problem. But if you use the TAE Core in a small studio—where one less cable is one less headache—or you prefer to interface with the TAE Core app on a desktop where you can toggle fast and easily between large, multi-track sessions and the app, the inability to work wirelessly on a desktop can be a distraction. The upside is that the TAE Core app itself is, functionally and visually, almost identical in mobile and desktop versions, enabling you to select and drag and drop virtual microphones into position, add delay, reverb, compression, and EQ effects, choose various cabinets with different speaker configurations and sizes, and introduce new rigs and impulse responses to a tone recipe in a flash. And though the TAE Core app lacks some of the photorealistic panache and configuration options in the OX app, the TAE Core’s app is just as intuitive.Less Is More
One nice thing about the TAE Core’s more approachable $699 price is that you don’t have to feel too bad on nights that you “underutilize” the unit and employ it as an attenuator alone. In this role, the TAE Core excels. Even significantly attenuated sounds retain the color and essence of the source tone. Like any attenuator-type device, you will sacrifice touch sensitivity and dynamics at a certain volume level, yielding a sense of disconnection between fingers, gut, guitar, and amp. But if you’re tracking “big” sounds in a small space, you can generate massive-sounding ones without interfacing with an amp modeler and flat-response monitors, which is a joy in my book. And again, there’s the TAE Core’s ability to “expand” as well as attenuate, which means you can use the TAE Core’s 30-watt onboard power amp to amplify the signal from, say, a 5-watt Fender Champion 600 with a 6" speaker, route it to a 2x12, 4x12, or virtual equivalent in the app, and leave your bandmate with the Twin Reverb and bad attitude utterly perplexed.
The Verdict
Opting for the simpler, thriftier TAE Core requires a few sacrifices. Power users that grew accustomed to the original TAE’s super-tunable “resonance-Z” and “presence-Z” controls, which aped signal-chain impedance relationships with sharp precision, will have to make do with the simpler but still very effective stack and combo options and the “air feel level” spatial ambience control.The DC power jack is less robust. It features only MIDI-in rather than MIDI-in/-through/-out jacks, and, significantly, 70 watts less power in the onboard power amp. But from my perspective, the Core is no less “professional” in terms of what it can achieve on a stage or in a studio of any size. Its more modest feature set and dimensions are, in my estimation, utility enhancements as much as limitations. If greater power and MIDI connectivity are essentials, then the extra 600 bones for the original TAE will be worth the price. For many of us, though, the mix of value, operational efficiencies, and the less-encumbered path to sound creation built into the TAE Core will represent a welcome sweet spot that makes dabbling in this very useful technology an appealing, practical proposition.
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.
Announced at the 2025 NAMM show, Cory Wong’s new collaboration with Ernie Ball Music Man scratched an itch—namely, the itch for a humbucker-loaded guitar that could appease Wong’s rock-and-R&B alter ego and serve as complement to his signature Fender Strat. Inspiration came from no further than a bandmate’s namesake instrument. Vulfpeck bassist Joe Dart has a line of signature model EBMM basses, one of which uses the classic StingRay bass body profile. So, when Wong went looking for something distinctive, he wondered if EBMM could create a 6-string guitar using the classic StingRay bass body and headstock profile.
Ernie Ball Music Man StingRay II ReviewErnie Ball Music Man StingRay II ReviewDouble the Fun
Wong is, by his own admission, a single-coil devotee. That’s where the core of his sound lives and it feels like home to him. However, Wong is as inspired by classic Earth, Wind & Fire tones and the pop-punk of the early ’90s as he is by Prince and the Minneapolis funk that he grew up with. The StingRay II is a guitar that can cover all those bases.
Ernie Ball has a history of designing fast-feeling, comfortable necks. And I can’t remember ever struggling to move around an EBMM fretboard. The roasted maple C-shaped neck here is slightly thicker in profile than I expected, but still very comfortable. (I must also mention that the back of the neck has a dazzling, almost holographic look to the grain that morphs in the light). By any measure, the StingRay II’s curves seemed designed for comfort and speed. Now, let’s talk about those pickups.Hot or Not?
A few years ago EBMM introduced a line of HT (heat-treated) pickups. The pickups are built with technology the company used to develop their Cobalt and M-Series strings. A fair amount of the process is shrouded in secrecy and must be taken on faith, but EBMM says treating elements of the pickup with heat increases clarity and dynamic response.
To find out for myself, I plugged the StingRay II into a Fender Vibroverb, Mesa/Boogie Mark VII, and a Neural DSP Quad Cortex (Wong’s preferred live rig). Right away, it was easy to hear the tight low end and warm highs. Often, I feel like the low end from neck humbuckers can feel too loose or lack definition. Neither was the case here. The HT pickup is beautifully balanced with a bounce that’s rich with ES-335 vibes. Clean tones are punchy and bright—especially with the Vibroverb—and dirty tones have more room for air. Individual notes were clear and articulate, too.
Any guitar associated with Wong needs a strong middle-position or combined pickup tone, and the StingRay II delivers. I never felt any significant signal loss in the blended signal from the two humbuckers, even if I could use a bit more midrange presence in the voicing. The midrange gap is nothing an EQ or Tube Screamer couldn’t fix, though. And not surprisingly, very Strat-like sounds were easy to achieve for having less midrange bump.
Knowing Wong’s love for ’90s alt-rock, I expected the bridge pickup to have real bite, and it does, demonstrating exceptional dynamic range and exceptional high-end response that never approached shrill. Nearly every type of distortion and overdrive I threw at it sounded great, but especially anything with a scooped-mid flavor and plenty of low end.
The Verdict
By any measure, the StingRay II is a top-notch, professional instrument. The fit and finish are immaculate and the feel of the neck makes me wonder if EBMM stashes some kind of secret sandpaper, because I don’t think I’ve ever felt a smoother, more playable neck. Kudos are also due to EBMM and Wong for finding an instrument that can move between ’70s George Benson tones and the hammering power chords of ’90s Blink-182. Admittedly, the nearly $3K price could give some players pause, but considering the overall quality of the instrument, it’s not out of line. Wong’s involvement and search for distinct sounds makes the StingRay II more than a tired redux of a classic model—an admirable accomplishment considering EBMM’s long and storied history.
