We've discussed full out-of-phase and half out-of-phase pickup switching. Here's a wiring for those who want it all in one switch.
Hello and welcome back to Mod Garage. After exploring the half out-of-phase pickup option several times in the past, there was a lot of interest, and I received a lot of emails from readers about it. A lot of you asked for a multi-phase switch to have all possible options at the ready and today we'll bring it all together. You asked for it, and the Mod Garage delivers!
Let's start with what we'll need to get out-of-phase or half out-of-phase sounds:
- You will need to engage at least two pickups to get such sounds. A single pickup played by itself will always sound the same, no matter if you play it in phase or out of phase (more about this later). The magic starts when you engage two (or more) pickups with one in phase and the other one out of phase or half out of phase.
- In general, you'll need one switch for each pickup you want to put out of phase. This can be only one switch, like on the middle pickup of a Stratocaster, to cover both in-between switching positions (bridge+middle and neck+middle), or three phasing switches, like on Brian May´s "Red Special," with one switch for each of the three pickups.
My design of a multi-phase switch that we'll cover today can be used to expand already existing out-of-phase switches in a guitar or to design a new wiring of your choice, integrating such a switch. With this switch, you'll be able to cover all three possible phasing options: in phase, out of phase, and half out of phase.
The magic starts when you engage two (or more) pickups with one in phase and the other one out of phase or half out of phase.
All you need for this mod is the switch, plus a capacitor and a resistor for the half out-of-phase option. So, let's start with the switch itself. For this mod you need a 4PDT on-on-on switch, which means a switch with three switching positions (up-middle-down) and a total of 12 lugs, arranged in four independent sections. Such switches are on the border of being exotic, but they're still available. Since every manufacturer uses a slightly different switching matrix for such switches, you'll need to get one with the same switching matrix I used, which is more or less the quasi-standard for it. It's possible to use 4PDT switches with a different switching matrix, but you'd have to adopt the wiring to it. I've provided three photos of the switching matrix and the switch design for each position. Photo 1 shows the "up" position, which will put the pickups half out-of-phase. Photo 2 shows the "middle" position, which will give you the full out-of-phase option. And Photo 3 shows the "down" position, which is just the normal in-phase operation.
Placing such physically large-sized switches on a pickguard or control plate can be a challenge, so you'll have to be creative. There is no way around such a switch when you want this mod because there are no existing push-pull or push-push pots with on-on-on switches. If you can find a 4P3T rotary switch, you can use it to substitute the switch by replacing one of the pots with it. There are also 4PDT slider switches available, but they're physically about the same size, and therefore, not a real alternative.
Photo 2 shows the 4PDT switching matrix design for the "middle" position, which will give you the full out-of-phase option.

Here we go with the wiring of the switch, shown in Fig. 1. With the lever down you have the normal in-phase operation, with the lever up the pickup is half-out-of-phase, and in the middle position you have the full out-of-phase option.
Anyway, there you have it, all in one switch as shown in Fig. 1. On the left side of the switch, you see a capacitor in series with a resistor for the half out-of-phase option. A good average value is using a 0.01 uF capacitor with a 6.2k-ohm resistor in series as an additional serial attenuation of the system, preventing an impedance peak.
When looking at the switch, you'll notice that one switching stage is not populated at all. You might ask: Why don't we use a 3PDT switch for this if we only need three switching stages? This is because of the asymmetrical switching matrix of the 4PDT switches in the middle position (Photo 2) and there's no way around it. If the on-on-on switch had a completely symmetrical switching matrix, then three switching stages would be enough, but such switches aren't available today.
Photo 3 shows the 4PDT switching matrix design "down" position, which is just a normal in-phase option.

In general, you add a controlled degree of reversed phase of the pickup when using the half out-of-phase option, which is great to mimic Stratocaster in-between "quack tones" on a Telecaster, like on the Jerry Donahue Tele models or with the Bill Lawrence Telecaster wiring.
Phase differences are measured in degrees. Totally in-phase sounds have either 0 or 360 degrees of difference, meaning none. Totally out-of-phase sounds have a 180-degree difference. So, half out of phase is either 90 or 270 degrees of difference. That's the reason why you can only achieve a fully out-of-phase effect when using two pickups together with one wired out-of-phase. (When both pickups are wired out of phase, they sound the same as both pickups in phase, because there are still 0 degrees of phase difference between them.) When a signal passes through a capacitor, the voltage leads the current by 90 degrees, so when a pickup's signal gets routed through a capacitor, it shifts the phase by 90 degrees—exactly half of 180 degrees—and therefore half out-of-phase ... in simple terms.
The cap connected to the switch is the phase-shifting cap mentioned above. A 0.01 uF cap is a great starting point, but you may try caps between 0.005 uF (5000 pF) and 0.022 uF. The smaller the cap, the sweeter the sound will be, but this really depends on your particular pickups. I recommend experimentation and fine-tuning to get as close as possible to a Strat's in-between tones.
As for the attenuation resistor, a 6.2k-ohm resistor works pretty well with the 0.01 uF cap and standard single-coil pickups. As a simple guideline, you can follow this rule by choosing and experimenting with this resistor: The higher the value, the more attenuation in the system, the smaller the impedance peak. A good starting point is the DCR of the pickup that's connected to the switch. For example, if your pickup measures a DCR of 6.8k ohms, you should start with a 6.8k-ohm resistor on the switch for a balanced sound and experiment from there. A good option is to use a small trim pot first so you can experiment until you find the value you like best. You can measure the trim pot and solder a fixed resistor with the measured value on the switch, or simply leave the trim pot where it is. A 10k or 15k trim pot is perfect for this.
That's it for this round. In honor of Fender's 75th Anniversary, next month we'll take a deeper look into Fender's history, busting some myths, misunderstandings, and urban legends, while celebrating the man behind the company that started it all: Mr. Clarence Leonidas Fender, or Leo Fender, as the world calls him.
Until then ... keep on modding!

Elliott Sharp is a dapper dude. Not a dandy, mind you, but an elegant gentleman.
The outside-the-box 6-string swami pays homage to the even-further-outside-the-box musician who’s played a formative role in the downtown Manhattan scene and continues to quietly—and almost compulsively—shape the worlds of experimental and roots music.
Often the most potent and iconoclastic artists generate extraordinary work for decades, yet seem to be relegated to the shadows, to a kind of perma-underground status. Certainly an artist like my friend Elliott Sharp fits this category. Yes, his work can be resolutely avant-garde. But perhaps the most challenging thing about trying to track this man is the utterly remarkable breadth of his work.
I am writing this piece for a guitar magazine, so, necessarily, I must serve up info that is guitar-centric. And I can do that, at least a little bit. But Elliott is also a noted composer, runs his own little record label, plays woodwinds proficiently, is a guitar builder/tinkerer, author, gracious supporter of other musicians’ efforts, family man, and killer blues player—a blues scholar, in fact. So where do we, the public, conditioned to needing categories, pigeonholes, and easy assessment signals, put Elliott Sharp—an artist with a powerful work ethic and a long, illustrious career of making mind-bending sounds and conceptual works? How about putting him in the pantheon of the maverick and the multifaceted? Surely this pantheon exists somewhere! In mind, in heart. To those for whom such things resonate and inspire, I bring you Elliott Sharp.
One can obviously go to the information superhighway to find info on Elliott, and to hear his music, so I won’t go into too many details about where he was born (Cleveland) and when (March 1, 1951; as of this writing, Elliott is 74), or what he is best known for (being a crucial figure in the downtown New York City scene from 1979 to the present). He is Berlin Prize winner and a Guggenheim Fellow (among other honors). And I have never asked him what strings and picks he uses, so maybe I have already blown it here. But I realize now, having taken on this assignment, that inherent in writing about and trying to explain Elliott Sharp is an implicit TMI factor. There is so much going on here, so much diverse information that could be imparted, that I would not be the least bit surprised if some readers eventually glaze over a bit and start thinking of their own life’s efforts and goals as rather paltry. I get that! Although you shouldn’t.
E# @NaturalHabitat
Here, now, is my portrait of Elliott, accompanied by what I imagine is a day in the life of Elliott when he’s at home in New York City.
Elliott Sharp is a dapper dude. Not a dandy, mind you, but an elegant gentleman. He, like so many in New York and in the world of music/art/guitar, favors dark-hued clothing (yeah, a preponderance of black) and is most often seen wearing a classic slouch hat of obvious quality. He relocated from Buffalo via Western Massachusetts to lower Manhattan in 1979 to a zone that was, back then, quite treacherously decrepit, in an apartment that offered only an hour or so of heat in the winter, etc., etc. It was cheap, and things were always happening, and, in fact, it was the 1950s domicile of William Burroughs, Allen Ginsberg, and Jack Kerouac.The area became the nexus of an ever-expanding circle of iconoclastic, experimental artists of many stripes.
Sharp plays what passes for a fairly staid instrument in his collection: a bass and guitar doubleneck, in 1992.
Elliott is still in that building in the East Village, though it is now only his workplace and not his living space. I am trying to remember exactly when I met Elliott, but it was probably about 25 years ago, and he still had only the one small, original apartment and a shared music space in the Garment District. I, like countless others before and after me, stayed in that East Village apartment whenever I needed a place to crash and Elliott was elsewhere, and eventually he was able to secure the next door apartment and expand his space. This is where Elliott Sharp works every day that he is not touring, pretty much 9 to 6. The place is a bit funky and dusty, and it is filled with instruments, amps (some classics, like a mid-’60s Princeton Reverb and a tweed Champ), and other tools accumulated over many decades—in spite of the many times that certain ones had to be sold to keep bread on the table.
When he’s not composing, scoring films, recording other artists, or gigging with the bands he has been in or led for the last several decades (Mofungo, Carbon/Orchestra Carbon, SysOrk, Terraplane, The Bootstrappers, Aggragat), Elliott tinkers with guitars, pedals, mandolins. Elliott is, to me, the king of guitar transformation, and his tinkering is stunningly Frankensteinian as he guts, rebuilds, and alters all kinds of stringed instruments, both electric and acoustic. He recently told me that in the ’60s he built fuzz boxes out of tobacco tins to make money. How cool would it be to have one of those now?? If one does a search on Elliott Sharp, many photos will reveal what I'm talking about: the handcrafted doubleneck he was most often seen playing in the ’80s (there was maybe more than one), 8-string guitars, modified Strat-type guitars with completely different pickups.. He also has a fancy guitar or two, such as his Koll fanned-fret 8-string, upon which he has played many a solo recital. During Covid time,, things were a little slow in the cash-flow department and, as a family man with twins, a little extra income was needed. So Elliott started building really cool-looking guitars out of cheap
ones and parts from wherever and refinishing them in hip and attractive ways and called them Mutantu. He sold them to friends and friends of friends. Yours truly basically only changes strings on his guitars, appealing helplessly to experts to do any kind of work on his guitars and amps, afraid of costly errors. The maverick and multifaceted among us, like Elliott, possess no such fear.
Even a leader in experimental 6-string gets a little guitar face now and then—especially when he’s playing blues.

So, back to that promised day in the life of Elliott Sharp (as imagined, with some degree of knowledge, by me): It’s early morning, and there is family to contend with. No bohemian lollygagging! So it’s feed the kids breakfast, do what parents must do. Then it’s off to the office (his studio), so Elliott dons a fine gray shirt (is that silk?), dark trousers, coat, and hat, and walks north from the family apartment on nearly the lowest point of eastern Manhattan to the East Village. The traffic and endless refurbishing of the Williamsburg Bridge roars familiarly overhead, the East River flows, and eventually a river of another kind, Houston Street, is crossed. Up the stairs to the fifth floor and the studio door is unlocked. Espresso is made. (There will be more of this.) The computer is turned on. And then ... who knows? Anything could be on the docket, but some sort of work will ensue for a good eight hours. Maybe a new graphic score for a German symphony is in the works (some of these have become visual artworks, too), or maybe it's time to try another mix of that Terraplane track, the one with Elliott’s friend, hero, and inspiration Hubert Sumlin—the one Elliott recorded not long before the famed Howlin’ Wolf guitarist joined his ancestors in the Great Beyond. Or maybe he’s recording a variation on his trio ERR Guitar (where he was originally joined by Marc Ribot and Mary Halvorson), called ERE Guitar Today, with Sally Gates and Tashi Dorji. Could happen—and it did. You can see Elliott’s studio in the ERE Guitar CD booklet.
Or maybe it’s guitar tinkering/building time. Where’s that delightfully chunky neck from China that would be awesome on that fake Tele body that was just refitted with no-name humbuckers (“sounded good once I removed the pickup covers,” Elliott observes) and a resophonic guitar tailpiece? By 5 or 6 it’s time to go home, maybe cook dinner tonight. And then ... my little imagined epic ends with a tasteful cinematic cliché: the dissolve.
The E# Way
Elliott Sharp has techniques that, in some cases, are all his own. No stranger to open tunings, prepared guitar, and other extended techniques, he often utilizes rhythmic, two-hand tapping to create spiraling, hypnotic patterns. His composing over these many years has employed and embraced genetics, Fibonacci numbers, algorithms, and fractal geometry. Though a mathematics and physics know-nothing myself, I see and hear a relationship between these elements as he has applied them to his uncompromisingly avant-garde compositions and these tapping patterns often heard in his solo work. Once he kicks in signal processing, stand back! What one hears sounds like four people (or other species and life forms), and the sensation is exhilarating. Sure, there could also be evidence of (here it comes) skronk (I can't believe I used that word), but Elliott certainly does not reside permanently in that world. Enjoying all kinds of sounds, from the lonesome moan of a resonator guitar to the aleatoric sputterings and squeals of a tormented electric guitar, is something he and I share, after all. Take, for example, two of his latest recordings on his zOaR imprint, Mandorleand Mandocello, which document his solo work on the two instruments, respectively. Both recordings investigate the instruments’ acoustic characteristics before, about half-way through, switching suddenly to electric, ultra-processed sounds. It’s a bracing experience that explains a few things about this man and the breadth of his aesthetic sweep. The sounds bring up images of recombinant DNA (information on which he has also imbued into his work), roiling lava, and the ever-expanding universe. Recommended!
Sharp applies his wicked two-handed-tapping technique to his 8-string, fanned-fret guitar built by Saul Koll.

So, this might fit into the aforementioned TMI category, but Elliott Sharp puts out a staggering amount of recordings. Every time I see him (which is not often enough), he has a little pile of compact discs for me, often on zOaR. I saw somewhere recently that he has released 165 recordings, but I think there are probably more than that. It’s hard for even the data lords to keep up! But it’s not always Elliott Sharp pieces or improvisation/collaborations on these albums. Other artists whom Elliott knows and respects can be represented, such as Spanish electric guitarist/conceptualizer A. L. Guillén, late bassist/producer Peter Freeman, Italian voice and guitar duo XIPE, or Hardenger fiddle player Agnese Amico—all articulate and singular musicians whom Elliott assists by releasing their music. I am grateful for this. It’s obviously more “work” for Elliott, and he accomplishes it, along with everything else he takes on or imagines doing, with elegant aplomb. Though obviously a nose-to-the-grindstone worker, Elliott is generally low-key and relaxed, even after those espressos.
The last thing I want to write about is Elliott's interpretations of the music of Thelonious Monk. Are you surprised, even after everything else you have just read, that something like that exists? In 2003, Elliott released a solo acoustic guitar recording called Sharp? Monk? Sharp! Monk!, and stunned the world (well, those few who pay attention to such things). However, my first exposure to Elliott's Monk interpretations was the more recent Monkulations, expertly recorded live in Vienna in 2007. (You can hear it on Bandcamp). These recordings are, justifiably I suppose, controversial in certain corners, because they do not adhere to Monk's exact written particulars note-for-note. Yet the mood, gestures, rhythmic wonders, and even the harmonic depth of Thelonious Monk often emerges, and frequently in astonishing ways. I understand why some would take issue with this approach because it departs significantly from the jazz tradition, but I find it remarkably fresh, bold, and so delightfully E#. They reveal an aspect of Elliott’s thinking and playing that is surprising in some ways, but also so him. It is clear to me that Elliott has seriously examined and internalized Monk’s repertoire.
Spring(s) in the garden: Sharp can use just about any tool in his improvisations.

Elliott is an artist who plays more than one instrument, plays them all in unique, startling, and often innovative ways, composes rigorous conceptual works from chamber music to operas, makes electronic music with no guitar, plays mean blues guitar like a swamp rat, authors books (I highly recommend his mostly memoir IrRational Music, and a second book is emerging this fall), builds and modifies guitars and other devices, is stunningly prolific, and is an elegant gentleman. The planet is a better place with him and his work in it. The maverick and multifaceted often have a rough road to tread, as we all know. So check out Elliott Sharp's vast world if any of this seems interesting to you. Thanks, Elliott!

The least exciting piece of your rig can impact your tone in a big way. Here’s what you need to know.
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.
Diagram courtesy Professor Manfred Zollner (https://www.gitarrenphysik.de)
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.
Diagram courtesy Professor Manfred Zollner (https://www.gitarrenphysik.de)
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!
Do you overuse vibrato? Could you survive without it?
Vibrato is a powerful tool, but it should be used intentionally. Different players have different styles—B.B. King’s shake, Clapton’s subtle touch—but the key is control. Tom Butwin suggests a few exercises to build awareness, tone, and touch.
The goal? Find a balance—don’t overdo it, but don’t avoid it completely. Try it out and see how it changes your playing!
By refining an already amazing homage to low-wattage 1960s Fenders, Carr flirts with perfection—and adds a Hiwatt-flavored twist.
Killer low end for a low-wattage amp. Mid and presence controls extend range beyond Princeton or tweed tone templates. Hiwatt-styled voice expands vocabulary. Built like heirloom furniture.

Carr Skylark Special
carramps.com
Steve Carr could probably build fantastic Fender amp clones while cooking up a crème brulee. But the beauty of Carr Amps is that they are never simply a copy of something else. Carr has a knack for taking Fender tone and circuit design elements—and, to a lesser extent, highlights from the Vox and Marshall playbook—and reimagining them as something new.
Those that playedCarr’s dazzling original Skylark know it didn’t go begging for much in the way of improvement. But Carr tends to tinker to very constructive ends. In the case of the Skylark Special, the headline news is the addition of the Hiwatt-inspired tone section from theCarr Bel-Ray, a switch from a solid-state rectifier to an EZ81 tube rectifier that enhances the amp’s sense of touch and dynamics, and an even deeper reverb.
Spanning Space Ages
With high-profile siblings like the Deluxe, Bassman, Tremolux, and Twin, Fender’s original Harvard is, comparatively, a footnote in Fender’s wide-panel tweed era (the inclusion of Steve Cropper’s Harvard in the Smithsonian notwithstanding). But the Harvard is somewhat distinctive among tweed Fenders for using fixed bias, which, given its power, makes it a bridge that links in both circuit and sound to the Princeton Reverb. The Skylark Special’s similar capacity for straddling tweed and black-panel touch and tone is fundamental to its magic.
Like the Harvard and the Princeton, the Skylark Special’s engine runs on two 6V6 power tubes and a single 12AX7 in the preamp section. A 12AX7 and 12AT7 drive the reverb and the reverb recovery section, respectively, and a second 12AT7 is assigned to the phase inverter. (The little EZ81 between the two 6V6 power tubes is dedicated to the rectifier). Apart from the power tubes and the 12AX7 in the preamp, however, the Skylark Special deviates from Harvard and Princeton reverb templates in many important ways. Instead of a 10" Jensen or Oxford, it uses a 50-watt 12" Celestion A-Type ceramic speaker, and it includes midrange and presence controls that a Harvard or Princeton do not. It also features a boost switch that manages to lend body and brawn without obliterating the core tone. There is also, as is Carr’s style, a very useful attenuator that spans zero to 1.2 watts. Alas, there is no tremolo.
“I’d wager the Skylark Special will be around every bit as long as a tweed Harvard when most of your printed-circuit amps have shoved off for the recycler.”
It goes without saying, perhaps, that the North Carolina-built Skylark Special is made to standards of craft that befit its $3K-plus price. Even still, Carr upgraded nine of the coupling capacitors to U.S.-made Jupiters. They also managed to shave six pounds from the Baltic birch cabinet weight—reducing total weight to 35 pounds and, in Steve Carr’s estimation, improving resonance. Say what you will about the high price, but I’d wager the Skylark Special will be around every bit as long as a tweed Harvard when most of your printed-circuit amps have shoved off for the recycler.
Sweet Soulful Bird
Fundamentally, the Skylark Special launches from a Fender space. But this is a very refined Fender space. The bass is rich, deep, and massive in ways you won’t encounter in many 12-watt combos, and the warm contours at the tone’s edges lend ballast and attitude to both clean tones and the ultra-smooth distorted ones at the volume’s higher reaches. All of these sounds dovetail with the clear top end you imagine when you close your eyes and picture quintessential black-panel Fender-ness. The presence and midrange controls, along with the 50-watt speaker, lend a lot in terms of scalpel-sharp tone shaping—providing a dimension beyond classical Fender-ness—especially when you bump the midrange and turn up your guitar volume.
The tube rectifier, meanwhile, shifts the Skylark Special’s touch dynamics from the super-immediate reactivity of a solid-state rectifier to a softer, more-compressed, more sunset-hued kind of tactile sensitivity. But don’t let that lead you to worry about the amp’s more explosive capabilities. There is more than enough high-midrange and treble to make the Skylark Special go bang.
Anglo and Attenuated Alter Egos
The Hiwatt-inspired setting is still dynamic, but it’s a little tighter than the Fullerton-voiced setting. There’s air and mass enough for power jangling or weighty leads. The differences in the Bel-Ray’s tube selection (EL84 power tubes as well as an EF86 in the preamp) means the Skylark Special’s version of the Hiwatt-style voice is—like the amp in general—warm and round in the low-mid zone and softer around the edges, where the Bel-Ray version has more high-end ceiling and less mellow glow in the bass. It definitely gives the Skylark Special a transatlantic reach that enhances its vocabulary and utility.
Attenuated settings are not just practical for suiting the amps to circumstances and size of space you’re in; they also offer an extra range of colors. The maximum 1.2 watt attenuated setting still churns up thick, filthy overdrive that rings with harmonics.
The Skylark Special’s richness and variation means you’ll spend a lot of time with guitar and amp alone. Anything more often feels like an intrusion. But the Skylark Special is a friend to effects. Strength in the low-end and speaker means it humors the gnarliest fuzzes with grace. And with as many shades of clean-to-just-dirty tones as there are here, the personalities of gain devices and other effects shine.
The Verdict
Skylark Special. It’s fun to say—in a hep-cat kind of way. The name is très cool, but the amp itself sounds fabulous, creating a sort of dream union of the Princeton’s and Harvard’s low-volume character, a black-panel Deluxe’s more stage-suited loudness and mass, and a zingier, more focused English cousin. It can be sweet, subdued, surfy, rowdy, and massive. And it works happily with pedals—most notably with fuzzes that can make lesser low-mid-wattage amps cough up hairballs. The price tag smarts. But this is a 12-watt combo that goes, sonically speaking, where few such amps will, and represents a first-class specimen of design and craft.
