The past and future of hexaphonic pickups.
But back to those six strings. The normal output signal of our standard pickups is a combined signal of any or all of the six strings. Six pole pieces, six strings. Wouldnāt it seem like a logical next step to separate the output signal of each string? In the long and varied history of guitar pickups it seems as if nearly every combination of materials has been tried and every shape and configuration explored. So how about this six-signal concept? It has been done, for various reasons and with varying levels of success. The beast in question is called the hexaphonic pickup.
The prefix hexa means six. Phonic means of, or relating to, sound. Six sounds. Just as a standard pickup does, the hexaphonic pickup captures the individual vibrations of each of a guitarās six strings. The difference is, rather than having a single output signal, the hexaphonic pickup has six. So who did it first, and whatās it good for? And why arenāt we all playing with hexaphonics?
In questions of firsts, I have two go-to sources: the US Patent Office and my friend and pre war-era guitar historian Lynn Wheelwright. An immediate problem in researching hexaphonics is that the word itself is a bit of a red herring in that it has not been the industry standard term. So in this particular case, I called Lynn first just to see if he remembered anything like it. He told me that the earliest pickup he had seen with anything similar to hexaphonic construction was on a Regal guitar from circa 1935ā36. This particular axe had a pickup unit with six individual coils, one for each string. It was not actually hexaphonic, though, because even with the six poles the pickup produced just a single output signal. On to the Patent Office where the earliest patent I could find using the specific terms āhexaphonic pickup systemā was awarded to Gibson in 1990 ... which seemed pretty late. We know that Bartolini Pickups founder Bill Bartolini was producing hexaphonics for public sale as early as 1973. Additionally, experimentation with polyphonic pickups for the purpose of hooking up guitars to synthesizers began in the early days of synthesizer development in the 1960s.
A hexaphonic pickup can have a number of uses. The most obvious is to send separate signals to separate places. In the analog realm, this might take the form of sending the bass strings to one amp, the treble to another. That effect was achieved in the mid-1950s by Ray Butts, who designed a split-coil pickup for Chet Atkins. Theoretically, separate signals for each string could be sent to individual inputs in the same amp where each input had its own volume control, compression, etc. Itās easy to see how rapidly the complexity quotient snowballs and how a standard amplification system might not be able to handle such an increased amount of information.
The first Roland synthesizer guitar, the GS-500, was introduced in 1977. It was with the Roland series of synth guitars, which continues to this day, that the hexaphonic pickup found its most widespread use. As a transducer for analog-to-digital sound, the hexaphonic pickup is the only way to go. For a guitar to control a synthesizer module (thereby allowing it to make sounds far beyond the normal guitar or guitar effects palette) each stringās signal needs to be isolated. An analog-to-digital converter requires that sounds be isolated, from string to string, in terms of pitch, and note start and stop. Converted to a digital signal, the Roland systems take the information from the guitar and turn it into sounds such as percussion, keys, saxophone, etc. The latest synth pickups on the market, such as the Roland GK-3 and the Axon PU100 designed in conjunction with Seymour Duncan, represent the latest technology in the field.
Some purists may balk, but my opinion is that synth guitar and its tonal possibilities would have been very popular with the players of yesterday. Alvino Rey used to have a sight gag in his act where he would ādeliverā a baby lap steel. Iād bet he would have loved to hook his lap steels up to a unit that could make each note sound exactly like a crying baby. Taking it in another direction, I think of hexaphonic pickups and wonder what it would have been like if one of the gods of guitar like Hendrix had had a separate Marshall stack for each string of his Strat. Perhaps cacophony; maybe brilliance. Either way, hexaphonic pickups and their ultimate utilization may be one of the last frontiers in the quest for the ultimate electric guitar tone.

The luthierās stash.
There is more to a guitar than just the details.
A guitar is not simply a collection of wood, wire, and metalāit is an act of faith. Faith that a slab of lumber can be coaxed to sing, and that magnets and copper wire can capture something as expansive as human emotion. While itās comforting to think that tone can be calculated like a tax return, the truth is far messier. A guitar is a living argument between its componentsāan uneasy alliance of materials and craftsmanship. When it works, itās glorious.
The Uncooperative Nature of Wood
For me it all starts with the wood. Not just the species, but the piece. Despite what spec sheets and tonewood debates would have you believe, no two boards are the same. One piece of ash might have a bright, airy ring, while another from the same tree might sound like it spent a hard winter in a muddy ditch.
Builders know this, which is why youāll occasionally catch one tapping on a rough blank, head cocked like a bird listening. Theyāre not crazy. Theyāre hunting for a lively, responsive quality that makes the wood feel awake in your hands. But wood is less than half the battle. So many guitarists make the mistake of buying the lumber instead of the luthier.
Pickups: Magnetic Hopes and Dreams
The engine of the guitar, pickups are the part that allegedly defines the electric guitarās voice. Sure, swapping pickups will alter the tonality, to use a color metaphor, but they can only translate whatās already there, and thereās little percentage in trying to wake the dead. Yet, pickups do matter. A PAF-style might offer more harmonic complexity, or an overwound single-coil may bring some extra snarl, but hereās the thing: Two pickups made to the same specs can still sound different. The wire tension, the winding pattern, or even the temperature on the assembly line that day all add tiny variables that the spec sheet doesnāt mention. Donāt even get me started about the unrepeatability of āhand-scatter winding,ā unless youāre a compulsive gambler.
āOne piece of ash might have a bright, airy ring, while another from the same tree might sound like it spent a hard winter in a muddy ditch.ā
Wires, Caps, and Wishful Thinking
Inside the control cavity, the pots and capacitors await, quietly shaping your tone whether you notice them or not. A potentiometer swap can make your volume taper feel like an on/off switch or smooth as an aged Tennessee whiskey. A capacitor change can make or break the tone controlās usefulness. Itās subtle, but noticeable. The kind of detail that sends people down the rabbit hole of swapping $3 capacitors for $50 āvintage-specā caps, just to see if they can āfeelā the mojo of the 1950s.
Hardware: The Unsung Saboteur
Bridges, nuts, tuners, and tailpieces are occasionally credited for their sonic contributions, but theyāre quietly running the show. A steel block reflects and resonates differently than a die-cast zinc or aluminum bridge. Sloppy threads on bridge studs can weigh in, just as plate-style bridges can couple firmly to the body. Tuning machines can influence not just tuning stability, but their weight can alter the way the headstock itself vibrates.
Itās All Connected
Then thereās the neck jointāthe place where sustain goes to die. A tight neck pocket allows the energy to transfer efficiently. A sloppy fit? Some credit it for creating the infamous cluck and twang of Fender guitars, so pick your poison. One of the most important specs is scale length. A longer scale not only creates more string tension, it also requires the frets to be further apart. This changes the feel and the sound. A shorter scale seems to diminish bright overtones, accentuating the lows and mids. Scale length has a definite effect on where the neck joins the body and the position of the bridge, where compromises must be made in a guitarās overall design. There are so many choices, and just as many opportunities to miss the mark. Itās like driving without a map unless youāve been there before.
Alchemy, Not Arithmetic
At the end of the day, a guitarās greatness doesnāt come from its spec sheet. Itās not about the wood species or the coil-wire gauge. Itās about how it all conspires to either soar or sink. Two guitars, built to identical specs, can feel like long-lost soulmates or total strangers. All of these factors are why mix-and-match mods are a long game that can eventually pay off. But thatās the mystery of it. You canāt build magic from a parts list. You canāt buy mojo by the pound. A guitar is more than the sum of its partsāitās a sometimes unpredictable collaboration of materials, choices, and human touch. And sometimes, whether in the hands of an experienced builder or a dedicated tinkerer, it just works.

MT 15 and Archon 50 Classic amplifiers offer fresh tones in release alongside a doubled-in-size Archon cabinet
PRS Guitars today released the updated MT 15 and the new Archon Classic amplifiers, along with a larger Archon speaker cabinet. The 15-watt, two-channel Mark Tremonti signature amp MT 15 now features a lead channel overdrive control. An addition to the Archon series, not a replacement, the 50-watt Classic offers a fresh voice by producing retro rock āclassicā tones reminiscent of sound permeating the radio four and five decades ago. Now twice the size of the first Archon cabinet, the Archon 4x12 boasts four Celestion V-Type speakers.
MT 15 Amplifier Head
Balancing aggression and articulation, this 15-watt amp supplies both heavy rhythms and clear lead tones. The MT 15 revision builds off the design of the MT 100, bringing the voice of the 100ās overdrive channel into its smaller-format sibling. Updating the model, the lead channel also features a push/pull overdrive control that removes two gain stages to produce vintage, crunchier āmid gainā tones. The clean channel still features a push/pull boost control that adds a touch of overdrive crunch. A half-power switch takes the MT to 7 watts.
āSeven years ago, we released my signature MT 15 amplifier, a compact powerhouse that quickly became a go-to for players seeking both pristine cleans and crushing high-gain tones. In 2023, we took things even further with the MT 100, delivering a full-scale amplifier that carried my signature sound to the next level. That inspired us to find a way to fit the 100's third channel into the 15's lunchbox size,ā said Mark Tremonti.
āToday, Iām beyond excited to introduce the next evolution of the MT15, now featuring a push/pull overdrive control on the Lead channel and a half-power switch, giving players even more tonal flexibility to shape their sound with a compact amp. Canāt wait for you all to plug in and experience it!ā
Archon Classic Amplifier Head
With a refined gain structure from the original Archon, the Archon Classicās lead channel offers a wider range of tones colored with gain, especially in the midrange. The clean channel goes from pristine all the way to the edge of breakup. This additional Archon version was developed to be a go-to tool for playing classic rock or pushing the envelope into modern territory. The Archon Classic still features the originalās bright switch, presence and depth controls. PRS continues to stock the Archon in retailers worldwide.
āThe Archon Classic is not a re-issue of the original Archon, but a newly voiced circuit with the lead channel excelling in '70s and '80s rock tones and a hotter clean channel able to go into breakup. This is the answer for those wanting an Archon with a hotrod vintage lead channel gain structure without changing preamp tube types, and a juiced- up clean channel without having to use a boost pedal, all wrapped up in a retro-inspired cabinet design,ā said PRS Amp Designer Doug Sewell.
Archon 4x12 Cabinet
As in the Archon 1x12 and 2x12, the mega-sized PRS Archon 4x12 speaker cabinet features Celestion V-Type speakers and a closed-back design, delivering power, punch, and tight low end. Also like its smaller brethren, the 4x12 is wrapped in durable black vinyl and adorned with a British-style black knitted-weave grill cloth. The Archon 4x12 is only the second four-speaker cabinet in the PRS lineup, next to the HDRX 4x12.
