State of the stump: Our columnist built this dub-inspired oscillator inside the shell of an old walkie-talkie bearing Radio Shack's Realistic brand name.
My phone has become a repository of gut shots and glamour shots of my pedal builds. Once a year or so, when it gets full, I dump the photos onto a hard drive for safe keeping. Every time I do, it turns into an all-day trip down memory lane. I go back—all the way back—to when I first started building pedals, and I look at my progression from then until now. I find it so rewarding to have a visual journal of all the work, love, and intention that I put into them. It's a representation of my learning journey and a reminder of how many friends I have made along the way.
Recently, as I was scrolling through, I found photos of what remains my favorite build to this day. I want to share my experience building it. As some of you know, I love to make guitar pedals out of broken, old electronic equipment. It's honestly my passion. In particular, I enjoy gutting busted walkie-talkies and building fun things inside. The old steel cases just look so cool! This particular Realistic Rover-1500 walkie-talkie became a dub-siren-turned-guitar-pedal. I named it the Loe-Fi Dub Siren. You can hear it on Instagram.
A dub siren is a type of synthesizer used predominantly in dub reggae. It is usually a relatively simple oscillator, housed in a box, often allowing for a variety of waveforms to be altered by turning potentiometers controlling pitch, rate, and other parameters. Dub sirens are frequently activated by a button and sometimes have the functionality to toggle between continuous synthesis with one button press or sound-emission-only when the button is held.
I just love it when there is an uninterrupted, smooth flow to a rather complicated build.
I built this oscillator circuit and added a small delay circuit to it as well. It sounded really cool and was fun to jam on during testing. I decided to take it one step further and add a sweep filter so that it could sound just like the King Tubby records I took my inspiration from. After I had it all finished, I had a thought: What if I add an input jack? Then, I could play guitar, or whatever, through it and play along with the oscillator. It took some figuring out, but eventually I got it all working. It was a pretty complicated build in the end.
I took my string-of-many-circuits that was ready to go and began the process of figuring out where everything was going to fit inside the walkie-talkie enclosure. This is probably the biggest challenge of all when building inside salvaged enclosures. They are often molded and, therefore, have a lot of odd protrusions to work around when considering where all of the circuit boards can be mounted. I also needed to figure out where the controls would go.
Next, came the drilling. Let me tell you, drilling steel is no fun! Not for me, anyway. Why did I have to put so many controls on this thing? After about an hour of careful drilling, the walkie-talkie was ready for population. I carefully followed my notes and built a little city inside. Then, I moved onto wiring. Many folks who build electronics loathe the wiring process, but I love it and enjoy the challenge of doing it neatly. Nothing gets me as excited as a gut shot with really tidy wiring.
This cool, jungle-themed badge on the side of Aisha Loe's Loe-Fi Dub Siren was painstakingly made from Shrinky Dinks. It took about 20 tries to get right.
After all the hardware and circuit boards were mounted, I tested the finished work. I made a few little last minute tweaks and deemed it ready for knobs. I ridiculously obsess over knob selection. I think it's a pretty common thing among pedal builders, actually. The knobs tie the whole thing together visually. A lot of thought goes into not only aesthetics, but also how they feel. They're going to get touched a lot, so they should feel nice!
As a finishing touch, I made a name badge for the finished pedal … out of Shrinky Dinks! (If you don't know that these are, google them. They're cool!) Yes, you read that correctly. I don't know why that idea popped into my head, but it did. So, I went with it. I learned that it takes about 20 tries to get it right! I vowed to never do that again. It does look pretty sweet, though.
I learned so much in the process of putting this pedal together. Sometimes my experiments lead me down paths that dead end. I learn a lot, whether it becomes a pedal at the end of my journey or not. This one gave me a win at every turn. Every idea and modification I had for it worked out so well. I just love it when there is an uninterrupted, smooth flow to a rather complicated build. The experience of building this dub siren is a cherished memory, and the pedal now belongs to one of my favorite musicians of all time. Dreams do come true! This build will always remind me of that.

Listen to visionary reggae producer King Tubby work the dub siren in his composition "Real Gone Crazy Dub." The sound is addictive, freaky, and psychedelic.

Elliott Sharp is a dapper dude. Not a dandy, mind you, but an elegant gentleman.
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!

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!
