You can get a surprising amount of tonal variety simply by getting creative with mic placement.
This month, we're going to look at an underused recording technique that can add depth and dimension to your guitar tone. This technique involves two mics: placing one in front of your open-back combo amp or open-back speaker cabinet (like normal) and one behind. A closed-back cabinet (like a 4x12) won't work for this technique, for obvious reasons. This may seem counterintuitive, but, as you'll see, this technique can be very useful—especially when trying to get a more full-bodied sound from a smaller, single-speaker, low-wattage combo amp like a Fender Princeton, Blues Junior, Champ, etc. The Dojo is now open. Let's get started.
Let's talk about the mics first. This technique is extremely flexible and doesn't require that your mics be a matched pair (same make and model). In fact, I've had better results by mixing and matching all kinds of mics! I highly encourage you to experiment and be creative. For this example, I'm going to use a dynamic mic (Shure SM57, $109 street) and a ribbon mic (Rode NTR, $799 street), but, again, any two mics will work regardless of price.
This technique is extremely flexible and doesn't require that your mics be a matched pair.
Mic 1: Shure SM57.
Of the two mics, the mic you use for the front of your amp should be the one you normally use and are most familiar with when recording (Photo 1). This way, you'll be able to have a point of reference as we move forward. After you've gone through this a couple of times, then switch it up, swap mics, and compare the differences.
Mic 2: Rode NTR.
Before placing the rear mic, there is something of critical importance you must do: flip the phase on the recording channel for mic 2. Because this rear microphone is pointed in the opposite direction, it is 180 degrees out of phase relative to mic 1 (Photo 2). We must correct that by flipping the phase on mic 2's mic pre or recording channel. If you don't, when you pull up both mic 1 and mic 2 and listen to them together, you'll find that your guitar tone will sound thin, hollow, and weak—which defeats the whole point of this technique!
Photo 2
I'll explain why this happens in the simplest way I can. When sound waves hit the diaphragm of a microphone (which is a transducer), those waves are converted into a tiny electrical signal with alternating positive and negative charges. When using two microphones pointed in opposite directions with the sound source (your amp's speaker) in the middle, mic 1 will receive a positive (+) charge while mic 2 will receive a negative (-) charge (Fig.1). This is because your amp's speaker can only move in one direction at a time, and it can't send a positive value in both directions simultaneously. This is what causes the phasing issue and why we need to flip the phase of mic 2 so that both mics add their energy together rather than subtracting from each other. Further, if you forget to flip the phase and just listen to only a single mic (mic 1 or mic 2 only), you won't hear the phase issue, but if you listen to both at the same time you will! So … flip the phase.
Fig. 1
Finally, where to place mic 2? There's not a right answer here, because there are too many variables: the dimensions of the amp itself, how open the back is, where the speaker is located (center, off to the left or right), etc. But I've consistently had good luck with placing the mic outside of the amp in the open space about four to six inches away from the back panel of the amp (Photo 3).
Photo 3
This will give you much more low-end information and beef up your sound. Typically, I'll use an SM57 (or similar) on the front of the amp and a ribbon for the rear, as in this column's example. Ribbon mics naturally have a beautiful low end with significant high-end roll-off the further we go up the frequency spectrum. By placing the darker mic on the back of a small combo amp, I can make it sound like a much bigger amp and get some added mojo as well.
See you next month!

AI, which generated this image in seconds, can obviously do amazing things. But can it actually replace human creativity?
Technology has always disrupted the music biz, but we’ve never seen anything like this.
AI has me deeply thinking: Is guitar (or any instrument) still valid? Are musicians still valid? I don’t think the answer is as obvious as I’d like it to be.
As a professional musician, I’ve spent the vast majority of my days immersed in the tones of tube amps, the resistance of steel strings under my fingers, and the endless pursuit of musical expression. Each day, I strive to tap into the Source, channel something new into the world (however small), and share it. Yet, lately, a new presence has entered the room—artificial intelligence. It is an interloper unlike any I’ve ever encountered. If you’re thinking that AI is something off in the “not-too-distant future,” you’re exponentially wrong. So, this month I’m going to ask that we sit and meditate on this technology, and hopefully gain some insight into how we are just beginning to use it.
AI: Friend or Foe?
In the last 12 months, I’ve heard quite a bit of AI-generated music. Algorithms can now “compose,” “perform” (with vocals of your choosing), and “produce” entire songs in minutes, with prompts as flippant as, “Write a song about__in the style of__.” AI never misses a note and can mimic the finer details of almost any genre with unnerving precision. For those who are merely curious about music, or those easily distracted by novelty, this might seem exciting … a shortcut to creating “professional” sounding music without years of practice. But for those of us who are deeply passionate about music, it raises some profound existential questions.
When you play an instrument, you engage in something deeply human. Each musician carries their life experiences into their playing. The pain of heartbreak, the joy of new beginnings, or the struggle to find a voice in an increasingly noisy and artificial online world dominated by algorithms. Sweat, tears, and callouses develop from your efforts and repetition. Your mistakes can lead to new creative vistas and shape the evolution of your style.
Emotions shape the music we create. While an algorithm can only infer and assign a “value” to the vast variety of our experience, it is ruthlessly proficient at analyzing and recording the entire corpus of human existence, and further, cataloging every known human behavioral action and response in mere fractions of a second.
Pardon the Disruption
Technology has always disrupted the music industry. The invention of musical notation provided unprecedented access to compositions. The advent of records allowed performances of music to be captured and shared. When radio brought music into every home, there was fear that no one would buy records. Television added visual spectacle, sparking fears that it would kill live performance. MIDI revolutionized music production but raised concerns about replacing human players. The internet, paired with the MP3 format, democratized music distribution, shattered traditional revenue models, and shifted power from labels to artists. Each of these innovations was met with resistance and uncertainty, but ultimately, they expanded the ways music could be created, shared, and experienced.
Every revolution in art and technology forces us to rediscover what is uniquely human about creativity. To me, though, this is different. AI isn’t a tool that requires a significant amount of human input in order to work. It’s already analyzed the minutia of all of humanity’s greatest creations—from the most esoteric to the ubiquitous, and it is wholly capable of creating entire works of art that are as commercially competitive as anything you’ve ever heard. This will force us to recalibrate our definition of art and push us to dig deeper into our personal truths.
“In an age where performed perfection is casually synthesized into existence, does our human expression still hold value? Especially if the average listener can’t tell the difference?”
Advantage: Humans
What if we don’t want to, though? In an age where performed perfection is casually synthesized into existence, does our human expression still hold value? Especially if the average listener can’t tell the difference?
Of course, the answer is still emphatically “Yes!” But caveat emptor. I believe that the value of the tool depends entirely on the way in which it is used—and this one in particular is a very, very powerful tool. We all need to read the manual and handle with care.
AI cannot replicate the experience of creating music in the moment. It cannot capture the energy of a living room jam session with friends or the adrenaline of playing a less-than-perfect set in front of a crowd who cheers because they feel your passion. It cannot replace the personal journey you take each time you push through frustration to master a riff that once seemed impossible. So, my fellow musicians, I say this: Your music is valid. Your guitar is valid. What you create with your hands and heart will always stand apart from what an algorithm can generate.
Our audience, on the other hand, is quite a different matter. And that’s the subject for next month’s Dojo. Until then, namaste.
Joni Mitchell’s rich, colorful altered-tuning chord voicings have set her work apart in its own musical universe, where the rest of us guitarists either scratch our heads in wonder or have to do dissertation-level research to unpack just how she gets her sound.
Joni Mitchell’s rich, colorful altered-tuning chord voicings have set her work apart in its own musical universe, where the rest of us guitarists either scratch our heads in wonder or have to do dissertation-level research to unpack just how she gets her sound. Dawes guitarist and songwriter Taylor Goldsmith gained firsthand experience with Mitchell’s songs when he joined her on stage—just check out 2022’s “Joni Jam” from the Newport Folk Festival, which also included Brandi Carlile, Blake Mills, Jon Batiste, and others.
Goldsmith joins us on this episode of the 100 Guitarists podcast. Together, we talk about Mitchell’s chord voicings and progressions, her tunings, what it’s like to share a stage with her, and Goldsmith wonders: Was Bob Dylan’s “Tangled Up in Blue” a nod to the songwriter’s 1971 album?
When we wrap up our conversation, we cover a new release of energetic, forward-leaning guitar cumbia by Los Pirañas and an album of Bach Partitas for Telecaster by guitarist Noel Johnston.

Some names you’ve heard, others maybe not. But they all have a unique voice on the instrument.

• Open your ears to new influences.
• Understand how to create interlocking rhythm parts.
• Develop a new appreciate for the rhythmic complexity of Wayne Krantz, the effortless bebop of Biréli Lagrène, and the driving force that is David Williams.
The guitar has been a major factor in so many styles of music over the last 70 years, and any experienced musician can tell you that playing any one of those styles with authenticity takes countless hours of dedication. As we learn the instrument, we seek out music that we find inspiring to help guide us toward our voice. The legends we all know in the guitar pantheon have inspired millions of players. In my musical journey over the years, I’ve always been thrilled to discover unique musicians who never attained the same recognition as their more famous counterparts. With so much music at our disposal these days, I thought this group of guitarists deserved a little more spotlight. The inspiration and knowledge they have provided me were paramount in my development, and I wouldn’t be the player I am without them.
Biréli Lagrène’s Bombastic Bop
Standards was the first jazz guitar record I really listened to, and his playing on this entire album is devastating. There is so much groove, joy, and ferocity in every note. The way he lays ideas out on the fretboard made a lot of sense to me, his rhythms were intentional and clear, and it was surprisingly easy to dig into as a rock guitarist at the time. He has an extensive catalog of jazz, gypsy jazz, and fusion records with some of the best in the world, and he’s also a killer bass player who can sing just like Frank Sinatra! Ex. 1 is over the first eight measures of “Stella by Starlight.” I stole so much vocabulary from this solo that I can still play bits from memory 20 years later. Lagrène’s treatment of two-measure chunks to play his ideas was significantly helpful. Whether it was an engaging rhythmic phrase, constant eighth-notes, or just cramming in as much as he could, I stopped worrying so much about catching every chord change after I learned this one.

Old-School Swing!
George Barnes is a unique jazz guitarist who was a contemporary of Charlie Christian, Johnny Smith, and Django. A significant part of his early work was writing and arranging for radio and television, for NBC, and he also wrote the very first electric guitar method book in 1942. A friend in Austin gave me two CDs of his: a collection of his playing from the Plantation Party radio show and an overview of his octet recordings. The octet recordings sound like unhinged cartoon music with guitar and orchestral instruments and are highly enjoyable. Ex. 2 is a line I lifted from a recording of him playing “Ain’t Misbehavin.” It was one of the hippest endings I have ever heard on a jazz tune, and although I can’t find the recording anywhere, I still use it all the time. I love the intention in George Barnes’ playing. Swinging and mischievous, he always sounds like he was having fun.

“Thrilling” Rhythm Solos
David Williams is one of the greatest rhythm players of all time. He is responsible for most of the memorable guitar moments on Michael Jackson’s records, and all his parts have an infectious nature. He is the primary reason I got interested in rhythm guitar, and he is still an inspiration on that front. One of my favorite examples of his playing is the breakdown in Michael Jackson’s “Thriller” (where Vincent Price does the rap). His signature thunderous right-hand approach to single-note rhythm parts is in full effect, and the natural accents between the two rhythm parts are infectious on their own but weave perfectly together. Ex. 3 is my interpretation of two interlocking parts in this style. He’s said in interviews that his concept as a player was to develop “rhythm solos” that could stand out front in a song, and this is a perfect example of that.

(Better than) Average Riffs
Though Hamish Stuart is most known for being an original member of the Average White Band, the singer/guitarist/composer/producer also did extensive work with heavyweights such as George Benson, Paul McCartney, Chaka Khan, and Aretha Franklin. Though AWB was still working until 1983, Hamish was doing sessions with various artists as a sideman in the early ’80s, including this excerpt from “Move Me No Mountain” off Chaka Khan’s Naughty from 1980 (Ex. 4). I’ve always loved the interplay between these two parts, range-wise and rhythmically. The lower pick line hits some unusual 16th-note placements, and the higher dyads have a churn to them that is amazing. Both parts together feel different rhythmically from anything I have ever heard but sound so cool and unique.

Wayne Krantz
Wayne Krantz is one of those guys that hit me like a lightning bolt. Upon hearing him, I felt like I had “permission” to play more with the fingers of my right hand, use jagged and intentional rhythms, and above all, to play more naturally. Wayne has always played like himself. His control over rhythm and articulation alone is legendary, not to mention the vast body of unique work he has created. Ex. 5 is an excerpt from the only solo I ever learned of his, from “Infinity Split” off 1999’s Greenwich Mean. I love this solo because it is incredibly engaging rhythmically and melodically, but almost 100 percent inside the harmony. This solo taught me more about rhythmic placement and articulation than anything.

Though I could only grab a certain percentage of these guys’ “vocabulary,” learning these parts over the years helped me find my sound. The result was an attempt to emulate some of their musicality in my way, rather than outright imitating them. Anything you hear that grabs your interest is probably worth sitting down and figuring out. While we might not mention the guitarists above alongside Hendrix or Van Halen, they have all done their part to put a brick in the cathedral, furthering music, and the instrument.
After surviving a near-death aortic dissection onstage, Richie Faulkner shredder has endured some health challenges. In this exclusive video, he opens up about how the cardiac event impacted his mental health both on- and offstage.
During Judas Priest's the Louder Than Life 2021 performance at the Louisville-based festival, lead shredder Richie Faulkner suffered an aortic dissection onstage. (It's worth noting, the steadfast professional finished the "Painkiller" solo before ending the set—an amazing feat.) He was rushed to the nearby University of Louisville hospital that saved his life. (Serendipitously, the hospital was only a few miles from the festival grounds.)
Faulkner fully recovered from the near-death experience but has endured other health setback stemming from the aortic dissection resulting in several issues including his right-hand coordination and strength. He's powered through the last 3+ years of performances and only now is open to talking about the difficulties he has playing the technical rhythm parts and how that's impacted his mental health both on- and offstage with the massive metal band.
