Stratocaster
Want a vast sonic palette at your fingertips? Here’s a way to get 10 unique sounds from one guitar.
Exactly 10 years ago, I wrote my first column for the publication that evolved into Premier Guitar, and as you can imagine, this is a landmark for me. To celebrate this decennial anniversary, I've cooked up something special. Fair warning: This is a complex mod, so it may not be for everyone. But even though the wiring resembles a circuit from the Apollo 12 mission, it's worth the work if you dream of having a vast sonic palette at your fingertips. The goal of this wiring is to create two independent switching stages: a standard Stratocaster setup mated with a typical PRS scheme. This “Strat-PRS crossover" will give you the best of both worlds in one guitar.
Overview and considerations.
For this project, you need a guitar with three pickups—neck and bridge humbuckers, plus a middle single-coil—wired to a special 5-way switch and master volume and master tone controls.
To get the required HSH configuration, you can take an existing dual-humbucker guitar and add a middle single-coil or replace a Strat's neck and bridge single-coils with humbuckers. For most guitars, this will necessitate body routing (a job for a pro) as well as a new pickguard.
A few other things to bear in mind: While it's possible to use single-coil-sized humbuckers, you'll get the best results using standard humbuckers with a middle single-coil. In particular, it's the PRS tones that benefit from this pickup mix.
Although the middle pickup can be any standard single-coil of your choice, both humbuckers must have 4-conductor wiring. If you have traditional 2-conductor humbuckers, you can either convert them to 4-conductor wiring or simply replace them with modern 4-conductor types. I suggest considering the latter, because converting a 2-wire humbucker to a 4-wire design entails removing the cover, and this exposes the extremely delicate coil wires. In this state, it's easy to damage the pickup. Unless you're comfortable with such an operation, take the pickups to your local tech or send them to a pickup manufacturer and ask them to do the conversion for you. Again, the safest option is to use stock 4-wire humbuckers, which are readily available from dozens of companies.
Also, when wiring two pickups together and splitting a humbucker, it's easy to get lost in all kinds of out-of-phase issues when you mix pickups from different makers. To avoid inadvertent phase problems, I highly recommend using all three pickups from the same manufacturer. This will ensure that both the polarity of the magnets and polarity of the individual coils—and this is especially critical for the humbuckers—are correct in relation to each other. (In future columns I'll go into this topic in greater detail and show you how to avoid any phase troubles right from the get-go.) If you intend to combine pickups from different companies, contact the manufacturers' service departments and explain what you want to do so they can guide you through the pickup selection process.
The nitty-gritty. For this mod, you'll need a 5-way switch with four, instead of the standard two, independent switching stages. The open-framed version of this switch is available from Fender as a 5-way Super Switch, but there are also PCB-based versions of this switch. To find out more about these switches, read "Introducing Fender's 5-Way Super Switch" and "Exploring Fender's 5-Way Super Switch."
Even though the wiring resembles a circuit from the Apollo 12 mission, it's worth the work if you dream of having a vast sonic palette at your fingertips.
This project also requires an additional switch to toggle between standard Strat and PRS modes. You can either add a 4PDT mini-toggle switch or replace one of the pots with a Fender S-1 push/push switching pot. I opted for the S-1 to keep the control layout as clean as possible, but if you want to install an additional switch instead, you can convert the S-1's switching matrix to your 4PDT switch.
Another item you'll need for this project is a 500k-ohm resistor. Any type and wattage will do; I use a 1/4-watt metal film resistor because it's small and easy to work with.
Both the master volume and tone pots are 500k, a value that makes sense for the PRS mode. For the Strat mode, we have a neat little trick I'll show you in a moment. As for the tone cap, a standard 0.022 µF value will work fine. If you want a little less capacitance, try a 0.015 µF or 0.01 µF value. Either will work great for the Strat mode. If you want, you can also incorporate the typical PRS treble bleed network between the volume's input and output to keep the high-end alive when rolling back the volume. This will work for the Strat mode as well, but not perfectly—give it a try and see what you think. The official PRS method is a 180 pF "cap only" wiring.
The following chart details the 10 pickup selections in our crossover wiring scheme.
The Strat mode yields five classic single-coil tones—bridge, middle, and neck pickups solo, plus a pair of dual-pickup settings. For the latter, the humbuckers are split and the active coil is wired in parallel to the middle single-coil to achieve the Strat's signature cluck in positions 2 and 4. Depending on the humbuckers, this can work quite well.
Pushing the S-1 down gives you the switching matrix of a modern PRS equipped with two humbuckers. Position 4 sounds similar to a Telecaster's middle position, with bridge and neck single-coils in parallel, and when you add that to the available Strat and full humbucker settings, you have a lot of tonal possibilities.
Hookup tips.
Because there are so many wires to connect, I recommend approaching this in two stages. Start by soldering all the jumper wires on the 5-way Super Switch (Fig. 1) and the S-1 pot (Fig. 2). It's much easier to solder these wires before mounting the components in the guitar.
Notice the additional 500k resistor on the S-1 switch, soldered between the switch and the lug that will ultimately connect to ground. This is a cool little gimmick to get a more classic Strat tone. Here's the lowdown: A standard Strat has three 250k pots, yet here we have two 500k pots—a configuration that gives the middle single-coil more highs than we're used to hearing on a Strat. By adding this 500k resistor in parallel, the middle single-coil will sound like it's in a 250k environment when the S-1 is in Strat mode.
Fig. 3 is the full schematic. I used Seymour Duncan's color code—a standard for such drawings. If you're using pickups from a different manufacturer, simply convert the color code of the wires, following the manufacturer's instructions. To keep the schematic as clean as possible, whenever multiple wires lead to the same spot, I combine them in the drawing. In such a complex wiring, it's very easy to mix something up, so be patient and work methodically. Go one step at a time and double-check each connection.
Next time, we'll begin investigating pickup parameters to learn how to interpret them and what they can tell us about a given unit's sound. Until then ... keep on modding!

An ode, and historical snapshot, to the tone-bar played, many-stringed thing in the room, and its place in the national musical firmament.
Blues, jazz, rock, country, bluegrass, rap.… When it comes to inventing musical genres, the U.S. totally nailed it. But how about inventing instruments?
Googling “American musical instruments” yields three.
• Banjo, which is erroneously listed since Africa is its continent of origin.
• Benjamin Franklin’s Glass Armonica, which was 37 glass bowls mounted horizontally on an iron spindle that was turned by means of a foot pedal. Sound was produced by touching the rims of the bowls with water-moistened fingers. The instrument’s popularity did not last due to the inability to amplify the volume combined with rumors that using the instrument caused both musicians and their listeners to go mad.
• Calliope, which was patented in 1855 by Joshua Stoddard. Often the size of a truck, it produces sound by sending steam through large locomotive-style whistles. Calliopes have no volume or tone control and can be heard for miles.
But Google left out the pedal steel. While there may not be a historical consensus, I was talking to fellow pedal-steel player Dave Maniscalco, and we share the theory that pedal steel is the most American instrument.
Think about it. The United States started as a DIY, let’s-try-anything country. Our culture encourages the endless pursuit of improvement on what’s come before. Curious, whimsical, impractical, explorative—that’s our DNA. And just as our music is always evolving, so are our instruments. Guitar was not invented in the U.S., but one could argue it’s being perfected here, as players from Les Paul to Van Halen kept tweaking the earlier designs, helping this one-time parlor instrument evolve into the awesome rock machine it is today.
Pedal steel evolved from lap steel, which began in Hawaii when a teenage Joseph Kekuku was walking down a road with his guitar in hand and bent over to pick up a railroad spike. When the spike inadvertently brushed the guitar’s neck and his instrument sang, Kekuku knew he had something. He worked out a tuning and technique, and then took his act to the mainland, where it exploded in popularity. Since the 1930s, artists as diverse as Jimmie Rodgers and Louis Armstrong and Pink Floyd have been using steel on their records.“The pedal steel guitar was born out of the curiosity and persistence of problem solvers, on the bandstand and on the workbench.”
Immigrants drove new innovations and opportunities for the steel guitar by amplifying the instrument to help it compete for listeners’ ears as part of louder ensembles. Swiss-American Adolph Rickenbacker, along with George Beauchamp, developed the first electric guitar—the Rickenbacker Electro A-22 lap steel, nicknamed the Frying Pan—and a pair of Slovak-American brothers, John and Rudy Dopyera, added aluminum cones in the body of a more traditional acoustic guitar design and created resophonic axes. The pedal steel guitar was born out of the curiosity and persistence of problem solvers, on the bandstand and on the workbench.
As the 20th century progressed and popular music reflected the more advanced harmonies of big-band jazz, the steel guitar’s tuning evolved from open A to a myriad of others, including E7, C6, and B11. Steel guitarists began playing double-, triple-, and even quadruple-necked guitars so they could incorporate different tunings.
In Indianapolis, the Harlan Brothers came up with an elegant solution to multiple tunings when they developed their Multi-Kord steel guitar, which used pedals to change the tuning of the instrument’s open strings to create chords that were previously not possible, earning a U.S. patent on August 21, 1947. In California, equipped with knowledge from building motorcycles, Paul Bigsby revolutionized the instrument with his Bigsby steel guitars. It was on one of these guitars that, in early 1954, Bud Isaacs sustained a chord and then pushed a pedal down to bend his strings up in pitch for the intro of Webb Pierce’s “Slowly.” This I–IV movement became synonymous with the pedal-steel guitar and provided a template for the role of the pedal steel in country music. Across town, church musicians in the congregation of the House of God Keith Dominion were already using the pedal steel guitar in Pentecostal services that transcended the homogeneity of Nashville’s country and Western clichés.
Pedal steels are most commonly tuned in an E9 (low to high: B–D–E–F#–G#–B–E–G#–D#–F#), which can be disorienting, with its own idiosyncratic logic containing both a b7 and major 7. It’s difficult to learn compared to other string instruments tuned to regular intervals, such as fourths and fifths, or an open chord.
Dave Maniscalco puts it like this: “The more time one sits behind it and assimilates its quirks and peculiarities, the more obvious it becomes that much like the country that birthed it, the pedal steel is better because of its contradictions. An amalgamation of wood and metal, doubling as both a musical instrument and mechanical device, the pedal steel is often complicated, confusing, and messy. Despite these contradictions, the pedal-steel guitar is a far more interesting and affecting because of its disparate influences and its complex journey to becoming America’s quintessential musical instrument.”The author dials in one of his 20-watt Sonzera amps, with an extension cabinet.
Knowing how guitar amplifiers were developed and have evolved is important to understanding why they sound the way they do when you’re plugged in.
Let’s talk about guitar amp history. I think it’s important for guitar players to have a general overview of amplifiers, so the sound makes more sense when they plug in. As far as I can figure out, guitar amps originally came from radios—although I’ve never had the opportunity to interview the inventors of the original amps. Early tube amps looked like radio boxes, and once there was an AM signal, it needed to be amplified through a speaker so you could hear it. I’m reasonably certain that other people know more about this than I do.
For me, the story of guitar amps picks up with early Fenders and Marshalls. If you look at the schematics, amplifier input, and tone control layout of an early tweed Fender Bassman, it’s clear that’s where the original Marshall JTM45 amps came from. Also, I’ve heard secondhand that the early Marshall cabinets were 8x12s, and the roadies requested that Marshall cut them in half so they became 4x12s. Similarly, 8x10 SVT cabinets were cut in half to make the now-industry-standard 4x10 bass cabinets. Our amp designer Doug Sewell and I understand that, for the early Fender amps we love, the design directed the guitar signal into half a tube, into a tone stack, into another half a tube, and the reverb would join it with another half a tube, and then there would be a phase splitter and output tubes and a transformer. (All 12AX7 tubes are really two tubes in one, so when I say a half-tube, I’m saying we’re using only the first half.) The tone stack and layout of these amps is an industry standard and have a beautiful, clean way of removing low midrange to clear up the sound of the guitar. I believe all but the first Marshalls came from a high-powered tweed Twin preamp (which was a 80-watt combo amp) and a Bassman power amp. The schematic was a little different. It was one half-tube into a full-tube cathode follower, into a more midrange-y tone stack, into the phase splitter and power tubes and output transformer. Both of these circuits have different kinds of sounds. What’s interesting is Marshall kept modifying their amps for less bass, more high midrange and treble, and more gain. In addition, master volume controls started being added by Fender and Marshall around 1976. The goal was to give more gain at less volume. Understanding these circuits has been a lifelong event for Doug and me.
Then, another designer came along by the name of Alexander Dumble. He modified the tone stack in Fender amps so you could get more bass and a different kind of midrange. Then, after the preamp, he put in a distortion circuit in a switchable in and out “loop.” In this arrangement, the distortion was like putting a distortion pedal in a loop after the tone controls. In a Fender amp, most of the distortion comes from the output section, so turning the tone controls changes the sound of the guitar, not the distortion. In a Marshall, the distortion comes before the tone controls, so when you turn the tone controls, the distortion changes. The way these amps compress and add harmonics as you turn up the gain is the game. All of these designs have real merit and are the basis of our modern tube–and then modeling—amplifiers.
Everything in these amps makes a difference. The circuits, the capacitor values and types, the resistor values and types, the power and output transformers, and the power supplies—including all those capacitor values and capacitor manufacturers.
I give you this truncated, general history to let you know that the amp business is just as complicated as the guitar business. I didn’t even mention the speakers or speaker cabinets and the artform behind those. But what’s most important is: When you plug into the amp, do you like it? And how much do you like it? Most guitar players have not played through a real Dumble or even a real blackface Deluxe Reverb or a 1966 Marshall plexi head. In a way, you’re trusting the amp designers to understand all the highly complex variations from this history, and then make a product that you love playing through. It’s daunting, but I love it. There is a complicated, deep, and rich history that has influenced and shaped how amps are made today.
Lenny Kravitz’s lead-guitar maestro shares how his scorching hit solo came together.
Hold onto your hats—Shred With Shifty is back! This time, Chris Shiflett sits down with fellow west coaster Craig Ross, who calls in from Madrid equipped with a lawsuit-era Ibanez 2393. The two buddies kick things off commiserating over an increasingly common tragedy for guitarists: losing precious gear in natural disasters. The takeaway? Don’t leave your gear in storage! Take it on the road!
Ross started out in the Los Angeles band Broken Homes, influenced by Chuck Berry, Buddy Holly, and the Beatles, but his big break came when he auditioned for Lenny Kravitz. Kravitz phoned him up the next day to tell him to be at rehearsal that evening. In 1993, they cut one of their biggest hits ever, “Are You Gonna Go My Way?” Ross explains that it came together from a loose, improvisatory jam in the studio—testament to the magic that can be found off-leash during studio time.
Ross recalls his rig for recording the solo, which consisted of just two items: Kravitz’s goldtop Les Paul and a tiny Gibson combo. (No fuzz or drive pedals, sorry Chris.) As Ross remembers, he was going for a Cream-era Clapton sound with the solo, which jumps between pentatonic and pentatonic major scales.
Tune in to learn how he frets and plays the song’s blistering lead bits, plus learn about what amps Ross is leaning on these days.
