Here's how to make your mono-tracked guitar solos—and more—sound larger than life.
Welcome back to the Dojo! This month I'm going to explain the Haas effect and how to use it on exposed parts (like your solo) and get it sounding wider than your speakers! I call it the "Haas Solo Effect"—a pun in tribute to my lifelong love of Star Wars. Tighten up your belts, we're going to throw around galactic-size audio. The Dojo is now open.
In 1949, Dr. Helmut Haas discovered a curious psychoacoustic phenomenon based on how our brains perceive the directionality of sound (also known as the "precedence effect"). This is based on what acousticians call HRTF (head-related transfer function), and it has everything to do with the time it takes for a sound wave to reach one ear and then the other ear that is the furthest away from the sound source. The longer the time, the more "hard panned" the sound becomes.
Try this: close your eyes, snap your finger at arm's length in front of you. The sound waves are reaching your ears at roughly the same time and your brain interprets this sound location as center (or directly in front of you). Now, do the same thing with your arm out to the side. Depending on which arm you used, the sound is either hard left or hard right. The last component to mention here is intensity (aka loudness). Obviously, the sound has greater intensity to the ear closest to the sound source and less so for the other ear. This makes up the two components we use to determine the directionality of sound: intensity (loudness) and timing (HRTF).
We can take advantage of this in our audio recordings—morphing a simple mono track to make it sound stereo, and then stretch it even wider. Try this on your lead vocal, guitar solo, or any mono track. Just be careful not to do this on every track, otherwise you'll get what I call "Big Mono," and nothing sounds like it's in stereo anymore. For our purposes, we're going to do this with a guitar solo.
"We can take advantage of this in our audio recordings—morphing a simple mono track to make it sound stereo, and then stretch it even wider."
Find your mono recorded guitar solo in your DAW session. Now duplicate it. Take the original and pan it hard left, and then pan the duplicate hard right. On the duplicate track, instantiate a delay [Fig. 1]. I'm using Soundtoys EchoBoy ($199 street), but any delay plug-in will work. Set the mix control to 100 percent wet. If it isn't already, set your delay time to milliseconds. For the Haas effect to work best, you can adjust the delay time anywhere between 1 and 40 milliseconds. (I used 27.4 ms in this case.) If you go over 40 milliseconds, you will gradually lose the ability to perceive the solo as one wide sound and you'll start hearing the duplicate track as a simple delay of the original, panned hard right.
To make sure it's working, bypass the delay altogether and listen to how everything immediately collapses back into the center of the stereo field, even though both tracks are panned hard left and right. Play around with the delay time of the duplicate track until you get it right where you want it.
Depending on what plug-in you choose, you may be able to score some Jedi bonus points here by playing around with other parameters. One thing I like to do is adjust the modulation properties of the delay (wow, flutter), which adds some analog tape artifacts. I'll also adjust the bit rate to give it a more lo-fi, bit-crushed kind of vibe. Waves H-Delay and, for the truly obsessed, FabFilter's Timeless, are good choices.
One last thing to add to your skill set: Remember the intensity component? I like playing with this one as well. Especially when I violate the Haas effect and go above 40 ms. When I do this, I can make it sound like the solo moves behind the beat and comes back into time in cool ways.
I did this on a song I wrote called "Making the Faith" on my new album Madrigals for Mongrels (coming soon). I used some choice lines from James Joyce's Finnegans Wake and peppered them in between guitar solos. You're welcome to come by my website, bryanclarkmusic.com, to hear it in action even before the album is released.
Until next time, stay creative, healthy, and keep experimenting. Namaste.

For anyone serious about mixing their own recordings, it’s a tool worth considering.
In the world of music production, the tools we choose profoundly influence the final sound of our recordings. I want to make the case for adding one tool that is rarely, if ever, in the “must have” or “sexy gear” spotlight but can deliver huge results to your mixes: the console summing mixer. Tighten up your belts—the Dojo is now open.
While digital audio workstations (DAWs) have revolutionized music production, offering unparalleled editing and flexibility, many producers, including me, still mix back into an analog console for the sonic character and three-dimensionality that it imparts. But buying a professional console isn’t cheap! This is where console summing boxes come into play, offering a unique way to enhance your mixes and elevate them to a professional level.
How Does It Work?
Very simply put, recording consoles have two basic sections: an input section (all the channels of mic pres, and EQ) and a center section (that sums all of the channels together and routes those signals to various configurable outputs such as inserts and aux buses). A console summing mixer is essentially the center section of a console and is designed to sum the individual audio channels, aux buses, stems, and submixes from your DAW in an analog domain.
In a DAW, digital summing—the process of combining multiple tracks and buses into a stereo mix—is handled through complex binary algorithms that, while precise, can sometimes lead to a mix that feels lifeless and one-dimensional, lacking the warmth, depth, and cohesion that analog consoles impart.
One of the most significant advantages of using a summing box is the introduction of harmonic distortion, a natural byproduct of analog circuitry. This isn’t like amp or pedal distortion, but rather a subtle harmonic saturation that adds richness and character to the sound. Low-end frequencies gain girth and definition, while high frequencies have a smooth, silky quality. You can achieve natural compression through subtle variations in phase and amplitude, but that depends on how hard you push the summing mixer box.
But the best benefit, in my opinion, is its ability to produce an undeniably open stereo image. Digital summing, while accurate, often lacks dimension or a sense of space. Analog summing introduces subtle variations in phase and amplitude, creating a sense of width and depth that makes each instrument feel like it occupies its own space in a more 3-D stereo field, which results in a more engaging and polished mix. I’ve also found summing boxes encourage a more deliberate and thoughtful approach to mixing, as it requires submixing certain elements.
API’s ASM164 ($3,195 street) is wildly flexible, offering VU meters, multiple inserts, two separate stereo mix options, and more.
For those who work “in-the-box” and aren’t in the market for a summing box, let alone a console, incorporating a summing box can also serve as a valuable learning tool. By running stems through a summing box and comparing the results to an entirely digital mix, you can train your ear to recognize the subtle qualities that make a mix feel warm, cohesive, spatial, and dynamic. This heightened awareness can then inform your in-the-box mixing decisions, even when you’re not using a summing box.
“Whether you want to add depth and dimension to your tracks, enhance your stereo image, or bring a touch of analog magic to your mixes, a summing box can be a gamechanger."
It’s important to choose the right summing box for your needs and budget, as different models offer varying sonic characteristics. Good summing mixers typically start around $2,000, such as Rupert Neve Design’s 5057 Orbit Summing Mixer. While more expensive, API’s ASM164 ($3,195 street) is wildly flexible, offering VU meters, multiple inserts, two separate stereo mix options, and more. The key here is to understand your needs.
Pairing a summing box with high-quality outboard processors, such as compressors or EQs, will allow you to shape your mix in ways that are impossible within a purely digital setup.
Whether you want to add depth and dimension to your tracks, enhance your stereo image, or bring a touch of analog magic to your mixes, a summing box can be a gamechanger. For anyone serious about mixing, it’s a tool worth considering—one that can make the difference between a mix that’s good and one that’s truly exceptional. Until next month, namaste
Guest columnist Dave Pomeroy, who is also president of Nashville’s musicians union, with some of his friends.
Dave Pomeroy, who’s played on over 500 albums with artists including Emmylou Harris, Elton John, Trisha Yearwood, Earl Scruggs, and Alison Krauss, shares his thoughts on bass playing—and a vision of the future.
From a very young age, I was captivated by music. Our military family was stationed in England from 1961 to 1964, so I got a two-year head start on the Beatles starting at age 6. When Cream came along, for the first time I was able to separate what the different players were doing, and my focus immediately landed on Jack Bruce. He wrote most of the songs, sang wonderfully, and drove the band with his bass. Playing along with Cream’s live recordings was a huge part of my initial self-training, and I never looked back.
The electric bass has a much shorter history than most instruments. I believe that this is a big reason why the evolution of bass playing continues in ways that were literally unimaginable when it began to replace the acoustic bass on pop and R&B recordings. Players like James Jamerson, Joe Osborn, Carol Kaye, Chuck Rainey, and David Hood made great songs even better with their bass lines, pocket, and tone. Playing in bands throughout my teenage years, I took every opportunity I could to learn from musicians who were more experienced than I was. Slowly, I began to understand the power of the bass to make everyone else sound better—or lead the way to a train wreck! That sense of responsibility was not lost on me. As I continued to play, listen, and learn, a gradual awareness of other elements came to the surface, including the three Ts: tone, timing, and taste.
I was ready to rock the world with busy lines and bass solos when I moved to Nashville in the late ’70s, and I was suddenly transported into the land of singer-songwriters. It was a huge awakening when I heard the lyrics of artists like Guy Clark, whose spare yet powerful stories and simple guitar changes opened up a whole new universe in reverse for me. It was a reset for sure, but gradually I found ways to combine my earlier energetic approach in different ways. Playing what’s right for a song is a very subjective thing.
“If the song calls for you to ramp up the energy and lead the way like Chris Squire, Bootsy Collins, Geddy Lee, Sting, Flea, Justin Chancellor, or so many others, trust yourself and go for it.”
Don Williams, whom I worked with for many years, was known as a man of few words, but he gave me some of the best musical advice I ever received. I had been with him for just a few months when he pulled me aside one night after a show, and quietly said, “Dave, you don’t have to play what’s on the records, just don’t throw me off when I’m singing.” In other words: It’s okay to be creative, but listen to what’s going on around you. I never forgot that lesson.
As I gradually got into recording work, in an environment where creativity is combined with efficiency and experimentation is sometimes, but not always, welcome, I focused on tone as a form of expression, trying to make every note count. As drum sounds got much bigger during the ’80s, string bass was pretty much off the table as an option in most situations. Inspired by German bassist Eberhard Weber, I bought an electric upright 5-string built by Harry Fleishman a few years earlier. That theoretically self-indulgent purchase gave me an opportunity to carve out a tone that would work with both big drums and acoustic instruments. It gave me an identifiable sound and led to me playing that bass on records with artists like Keith Whitley, Trisha Yearwood, Alison Krauss, Emmylou Harris, and the Chieftains.
In a world of constantly evolving and merging musical styles, the options can be almost overwhelming, so it’s important to trust yourself. Ultimately, you are making a series of choices every time you pick up the instrument. Whether it’s pick versus fingers versus thumb, or clean versus overdrive versus distortion, and so on … you are the boss of your role in the song you are playing. When the sonic surroundings you find yourself in change, so can you. It’s all about listening to what is going on around you and finding that sweet spot where you can bring the whole thing together while not attracting too much attention.
On the other hand, if the song calls for you to ramp up the energy and lead the way like Chris Squire, Bootsy Collins, Geddy Lee, Sting, Flea, Justin Chancellor, or so many others, trust yourself and go for it. Newer role models like Tal Wilkenfeld, Thundercat, and MonoNeon have raised the bar yet again. The beauty of it all is that the bass and its role keep evolving.
Right now, I guarantee there are young bassists of all descriptions we have not yet heard who are reinventing the bass and its role in new ways. That’s what bass players do—we are the glue that ties music together. Find your power and use it!
