Our columnist recounts what he’s learned about getting the sound of a projection cone to an audience, and his ultimate solution: two mounted mics and his faithful Super Reverb.
In my July 2022 column, “Acoustic Guitars and Fender Amps,” I talked about using acoustic 6-strings with classic black-panel amps—particularly the bigger models with wide EQ possibilities. This month, let’s take it a step further and talk about Fender amps and resonator guitars. I will share what I have discovered by experimenting with various microphones, pedals, and more.
In a resonator, the metal cone underneath the front plate functions as a base for the bridge saddle and vibrates like a loudspeaker to project sound. Because of the instrument’s directional character and ease of feeding back, resonator guitars are difficult to use in live bands with loud stage volume. The goal is to get enough volume resonator onstage and in the room without feedback. Since it’s an important part of the instrument’s character, it’s necessary to capture some of that metal-cone voice within an overall balanced guitar tone that sits well in the mix. And you need to be able to achieve this in a way simple enough to reproduce the same tone night after night, and focus on your music, not technical problems.
The easiest way to mic a resonator guitar is to place a microphone on a stand about a foot in front of the guitar and run the signal into the mixer. But this pure acoustic route only works well in low volume situations—due to feedback—and requires you to play sitting down or standing still.
“Because of the instrument’s directional character and ease of feeding back, resonator guitars are difficult to use in live bands with loud stage volume.”
You can also use the type of clip-on microphone (often used for violin) made by Neumann and DPA, among others, to make you mobile, but if you get too close to the monitors or mains, feedback ensues. I recommend the microphones that come with a preamp and volume dial, to give you the most control. If you use one of these, point the mic directly toward the metal cone. Finding a nice tone will require some experimentation.
Another option is a piezo pickup. Some newer resonator guitars come with factory-installed piezos. It’s not very difficult to install a passive piezo yourself. You need to file and sand the bridge piece, detach the metal cone for wiring and soldering work, and, finally, drill a hole in the guitar where the jack plug goes in through the strap button. Getting the string tension correct over the entire length of the bridge saddle is the key to success. Lately, I have used hard oak as bridge material, which creates a smooth and mellow tone with bronze strings.
The author’s resonator “kit.”
Piezo pickups are less prone to feedback than acoustic microphones, so they are better for high-volume stage scenarios. But piezo pickups alone will not fully capture the tone of the resonator cone, so if you’re looking for more of that, add an acoustic clip-on microphone. That’s what I do. Both the piezo and the clip-on go to my Fender Super Reverb, and I use the normal channel for the feedback-sensitive acoustic microphone while the piezo goes to the vibrato channel with reverb. For dirty tones, I sometimes use an overdrive pedal for the piezo pickup. There are independent EQ and volume settings on both channels.
The third and last microphone technique I have experimented with is a humbucker. I bought one from 12 Bar Blues Pickups that is only 6 mm tall and built specifically for resonators. It fits nicely under the strings with enough clearance. The advantage with a passive magnetic pickup is obviously the simplicity. The installation process is easy if you simply tape or glue the pickup to your guitar and let the wire run externally on top of your resonator’s body. The kit I bought contains a small volume and tone box with jack input, and requires no battery. The result is, essentially, a hollow-body electric guitar suited for pedals and regular amps. It is also more resistant to feedback than both piezo and acoustic microphones. When I want to add some of the “bluegrass” flavor of the resonator cone, I add the acoustic microphone as mentioned earlier.
One drawback with conventional magnetic pickup technology is that bronze strings have a lower output, since bronze is less responsive to magnetic fields than nickel. I have kept the bronze strings on my resonators because of the great tone. To get even output on the bass strings, the bridge height measures a little higher on the bass side than the treble side.
So, there we have several different techniques for capturing modern resonator guitar tones, including a few options with guitar amps. Now, go experiment!
The North Carolina amp builder is famous for his circuit-blending soundboxes, like the Rambler, Sportsman, and Telstar. Here, he tells us how he got started and what keeps him pushing forward.
Steve Carr started building amps because he loved playing guitar. He and his friends cobbled together a band in Michigan City, Indiana, in high school in the mid-’70s, and the gear they played with seemed like a black box. In the pre-internet days, getting information on amp voicings and pickup magnets was difficult. Carr was fascinated, and always wanted to know what made things tick.
After college, he moved to Chapel Hill, North Carolina, where he met an amp repairman that he started hanging around. He wanted to apprentice under the fellow and soak up his wisdom, but the guy wasn’t interested in taking on a student. “Finally, he said, ‘I don’t have time to have anybody around here, but you should do what I did when I was a kid, which is build a Fender tweed Champ,’” remembers Carr. He’d have to track down the schematic, figure out how to read it, source the necessary parts, then assemble the amp. Flipping through issues of Vacuum Tube Valley and Angela’s Instruments, he got on his way.
Building that Champ clone taught him how to navigate industrial parts suppliers, valuable know-how that would come in handy later on. At the end of the build, he flicked it on, and nothing happened. The amp wouldn’t sing. “I was super depressed,” Carr says. “I couldn’t believe it.” But he didn’t quit—he spent the next few weeks troubleshooting the circuit and got it to go. By then, in his mind, he was a bona fide amp repairman. Between Chapel Hill, Raleigh, Durham, and Greensboro, there were tons of young gigging bands who needed their amps in working order, so Carr got a breakneck crash course in amp repair over a few years. It wasn’t long before he thought: “Maybe I can make my own amp.”
Carr’s lineup has included 22 different amplifier models over its 26 years of business. Clockwise from top left, we have the Skylark, Rambler, and two Mercury Vs.

His initial idea was to combine two amps that he loved, his black-panel Fender Deluxe Reverb and 50-watt non-master-volume Marshall. He wanted to marry the Fender’s cleans and reverb with the roaring drive of the Marshall. The Frankenstein experiment produced Carr Amplifiers’ first amp: the Slant 6V. It was just intended for Carr’s personal use. But it wasn’t too long until his friends encouraged him to build more, and in the fall of 1998, he made his first two sales.
Eddie Berman was working at the Music Loft in Wilmington, North Carolina, when a local musician called him up to say that a friend of his was building amplifiers, and wanted to bring one by the shop. Carr brought those first two Slant 6Vs by, and Berman and his colleagues jammed on them at rehearsal that evening. “I went, ‘Oh my goodness, we have to have these amplifiers,’” says Berman. The clean channel was unbelievable, Berman continues—broad, cinematic, and sweet-sounding, free from any top-end harshness or “nails on the chalkboard” overtones. It was so intoxicating that he used to tease Carr: The clean channel was so good, why did he bother to put a dirty channel on, too?
There was more to the amps than just rich tone. Berman remembers that the first amp had the same electrical plug as one might find on hospital emergency room equipment. “We know anything that he touches is going to be golden,” says Berman. There was one other element, too: Steve Carr was just a good dude. Ph
From his very first build, Carr has manufactured his amps to impressive, durable specs—two different sources mentioned independently how robust and secure that even the amplifiers’ power cords are.

That was more than 26 years ago. Carr Amplifiers, located in Pittsboro, North Carolina, has grown into one of the most respected companies in the boutique amplification market, thanks to their versatility, exacting construction, and, of course, beautiful sounds.
In his first builds, Carr pioneered a combination that would become a signature for all his models: expensive polypropylene capacitors and more classic, old-school components like carbon-composition resistors. “Those two items have a certain sound that is a family trait in the amps, which is a very dynamic, open, transparent, but also a very warm and liquid sound, at once,” says Carr. “They’re sort of in a way opposite concepts, but they come together.”
Carr attributes his success in part to the initial demise of Matchless, the amp builder that helped carve out the beginnings of the boutique amp niche in the 1990s. When Matchless went out of business in 1998 (they returned some years later), Carr realized that their dealers would probably be looking for replacement amps in their shops to appease the boutique crowd, so he phoned them up and pitched his amps.
“Those two items have a certain sound that is a family trait in the amps, which is a very dynamic, open, transparent, but also a very warm and liquid, sound at once.” - Steve Carr
The business grew, and in May 1999, the Carr brand launched its second amp, the Rambler. Carr describes it as “a collage” of a black-panel Princeton Reverb and a tweed Pro. By this point, the rising amp-maker had solidified another characteristic: He liked squeezing two amps into one box, without sacrificing fidelity on either end. “At first, they don’t really want to work well together,” says Carr. There’s a whole lot of prototyping to get to the point where the circuits can behave copacetically, and represent both elements of their parent amplifiers without causing problems. But succeeding in that analog alchemy is one of Carr’s greatest achievements. “It’s got influences,” he continues, “but it becomes a new, unique amp.”
Working with expensive components, like choice capacitors and near-obsolete resistors, drives the price of Carr amps up, but Steve Carr insists that they make an audible difference. Here, Carr builder David Quick assembles a Mercury V.

Carr started building his noiseboxes out of the spare bedroom of his wife’s home in southern Chapel Hill, and after his first sales, he sprang for a wooden-floored barn in the woods. It had electricity, but that was about it: no HVAC, no water, no bathrooms. But the price was right, so he rented the spot and hired his first employee. The operation lasted a year there, where they built Slant 6Vs and Ramblers, the latter of which became the company’s first perennial seller and a favorite of Nashville session players. “The names of these folks, people may not know, but you’ve probably heard a lot of these session guys who’ve got Ramblers,” says Carr.
The “barn era” lasted about a year and a half, until Carr and his wife relocated to Pittsboro. He got a tip that some space was up for rent in an old chicken hatchery downtown, where they leased two rooms initially. When the business in the neighboring units moved out, Carr Amplifiers expanded to 4,500 square feet. They’ve remained in that building since, growing the operation to fill the high ceilings and spacious rooms.
One of the major additions to the business was in-house cabinetry building. In the early years, Carr hired carpenters from around the state who built cabinets for the amps. At one point, he was picking up cabs from a woodworker named Peter Mather in Virginia Beach, Virginia, loading up a van with 30 of the wooden frames. Even though it was wintertime, Carr drove with the windows down, because the glue applied to adhere the Tolex to the wood was still fresh, and the fumes were potent. Eventually, Mather, who passed away in 2023, offered to travel to Pittsboro to teach Carr and his staff how to manufacture the boxes. The onsite cabinet-making started in 2003, and in the two-decades-plus since, the team has developed their distinctive cabinet design into a key piece of their identity. It’s important that Carr cabs both look great and fit the physical needs of the circuitry inside.
At Carr, the name of the game is cutting cabs, not corners. Here, a stack of naked Bel-Ray frames show off the shop’s woodworking and design prowess.

“We have a certain aesthetic sense,” says Carr, naming 1920s through ’60s design and art trends, chiefly art deco, as major influences. “I’ve always wanted to have that in the cabinets, because so many guitar amps are very basic-looking, and if somebody’s buying something that’s handmade with great care, it seems to me that you want to make it fun-looking, too. You want to take that same care with the whole aesthetic look of it and make it a real pleasure to have. That’s been a goal from the beginning, and it’s part of why we decided to take the extra expense. There are a lot of machines you’ve got to buy to create a cabinet shop. But now we have control over the beauty of the design.”
But the box is only as good as what comes out of it. Carr says it takes roughly nine months of process between when he brainstorms a design and when it comes to life, but it always starts with a classic amp—or a few. “I often joke that it’s kind of a sonic divining rod, where I’ll start off somewhere and the amp eventually becomes what it wanted to become,” says Carr. “I’m just along for the ride.”

The Bel-Ray, released earlier this year, is Carr’s most ambitious design yet. Previous builds like the Super B and Mercury V incorporated rotary switches that allowed users to change between specific voicings—already a mean feat in a small combo with analog circuitry. But Carr wanted to take it a step further and create a combo amp with a “triumvirate of British amp voices”: classic Vox, Marshall, and Hiwatt noisemakers. It was a big challenge, he admits. The output section was fairly simple—two EL84 tubes—but Carr wanted to incorporate an EF86 pentode in the preamp. It has a distinct flavor from the two other 12AX7s in the preamp, but is so dynamic that the potential for microphonic problems is elevated. That took some finessing.
The tone stacks, though, were the most labor-intensive code to crack. It took Carr a long time to get the feel for Hiwatt’s midrange and treble signatures, which he likens to those of old Valco and Supro amps. While the Marshall and Vox tone architecture were similar enough in structure, the Hiwatt’s was trickier to squeeze in. “The parts just don’t connect in the same places or in the same way, so you’re not able to just change a value here and there; you have to change how it’s all hooked up,” he explains. To accomplish the complex maneuvering, the Bel-Ray uses a number of dual, stacked pots, and the rotary switch changes not just capacitor values, but also which deck of the dual pots the user is manipulating. “There was a lot of massaging and tweaking and thinking to get all three of those vibes there,” he says. “And then, the amp became its own thing. It has characteristics of all those [amps], but it’s not exactly those.”

Part of Carr Amplifiers’ “mojo” comes from Carr’s exacting standards for individual components, which contribute to the significant price tag on his amps. He favors U.S.-made signal capacitors from Ohio-based Jupiter Condenser Co., which are patterned after ’50s and ’60s caps but can cost 10 to 20 times more than the average capacitor. Another parts vendor sources him with his treasured, near-obsolete carbon-comp resistors. Unless you have a backstock (which he has amassed), Carr estimates you won’t be able to find them within a few years. This all might sound a bit over-the-top; how much difference can one tiny component make? Carr insists that when he’s testing components in the circuits, the value (pun intended, I guess) becomes clear.
“There’s a lot of really great amps out there, and I love a lot of amps. I’m not saying this is the only one, but it sure is a good one.” - Bill Frisell
It’s obvious that he’s onto something. In the early 2000s, Bill Frisell was in Nashville recording with bassist Viktor Krauss when Krauss loaned him a Carr Rambler to record with. He loved it. A while later, he played a Carr Mercury during a session in Portland, Oregon. “That’s where I really was like, ‘Oh man, I gotta check this out more,’” says Frisell. His parents were living in Chapel Hill, so during a visit, he popped down to Steve’s shop and picked up a Mercury of his own. When the Sportsman came out, Frisell bought one of those, too.
On the road, Frisell uses mostly Fender amps, but at home, he keeps his prized amplifiers: a small Gibson combo amp from the early ’60s, an early ’60s Fender Princeton, and his Carr Sportsman. “There’s this thing with these older amps,” says Frisell. “There’s a clarity and warmth that’s happening at the same time. I can’t put my finger on it when I try to describe the sound. Whatever it is with the Sportsman, that’s the one for me that has these qualities, these older amps that I love.

“Guitars and rock music have always been a fundamental part of my life,” says Yungblud. “Literally my education. I grew up on the counter of a guitar shop, and I’ve been dusting them since I was three years old. The reason why I play a White ‘64 SG Junior is because, growing up, musicians who were important in my life were Angus Young and Billie Joe Armstrong. I was lucky because I found a guitar that represented both parts of my inspiration and yet has been famously played by no one but me. This SG Junior is entirely my own, and it already looks fucking iconic.
Rock music only survives if we keep evolving the genre, playing it our own way, and passing along the fuckin’ baton. To play for my fan base, hand them my guitars and talk to them about wanting to start bands is the sickest shit ever!! If I play even the tiniest part in their journey, I’m fuckin’ honored. Rock isn’t dead; it’s just different, pass it on.”
The Yungblud SG Junior has a mahogany body and a glued-in mahogany neck with a SlimTaper C profile and a laurel fretboard that is equipped with 22 medium jumbo frets. Epiphone Deluxe Vintage tuners and a Graph Tech nut keep everything solidly in tune, while a compensated wraparound bridge anchors the strings at the other end and contributes to the models’ excellent sustain. The simple yet effective electronics include a single Dogear Epiphone P-90 Pro pickup in the bridge position, wired to CTS volume and tone potentiometers. An Epiphone hardshell case with a hot pink interior is also included, and a Yungblud die-cut bumper sticker is packed inside.

You probably know Ed Helms from his unforgettable turns in The Hangover movies, The Office, and a laundry list of era-defining comedies, but what you might not know is that he shreds bluegrass music, too. (Actually, if you’ve seen The Office, you’ll know about his impressive musicianship.) Helms has played in bluegrass bands since his college days, so he knows a thing or two about writing a great American roots song. And what’s more American than getting too pissed off and ruining nice things?
Helms joins Sean Watkins and Peter Harper for a writing session that centers on a paraphrased version of Abraham Maslow’s law of the instrument: “When all you’ve got is a hammer, everything’s a nail.” The trio use the phrase as a way to look at personal and societal inabilities to approach situations with “the right tool,” like nuance, patience, or grace. Instead, anger—the hammer—seems to be the only tool in our belts. That inevitably means we end up smashing stuff.

He was dubbed “the father of British blues,” but Mayall’s influence was worldwide, and he nurtured some of the finest guitarists in the genre, including Eric Clapton, Peter Green, Mick Taylor, Harvey Mandel, Coco Montoya, and Walter Trout. Mayall died at his California home on Monday, at age 90.
John Mayall’s career spanned nearly 70 years, but it only took his first four albums to cement his legendary status. With his initial releases with his band the Bluesbreakers—1966’s Blues Breakers with Eric Clapton; ’67’s A Hard Road, with Peter Green on guitar; plus the same year’s Crusade, which showcased Mick Taylor—and his solo debut The Blues Alone, also from 1967, Mayall introduced an international audience of young white fans to the decidedly Black and decidedly American genre called blues. In the subsequent decades, he maintained an active touring and recording schedule until March 26, 2022, when he played his last gig at age 87. It was reported that he died peacefully, on Monday, in his California home, at 90.
Mayall had just one radio hit, 1969’s FM staple “Room to Move,” from The Turning Point, a live album that captured his era of experimentation with pop and psychedelic elements in blues. But throughout the decades he remained a profoundly good musician and bandleader, who held his players to the highest standard. And what a coterie of players! He maintained a reputation for cultivating exceptional guitarists, from his early troika of Clapton, Green, and Taylor, to Harvey Mandel, Coco Montoya, and Walter Trout, and, more recently, Buddy Whittington and Carolyn Wonderland.
Eric Clapton described him as “having the air of a favorite schoolmaster who still manages to be cool.”
But it wasn’t just the company he kept that made him legendary. Mayall’s carefully curated choice of material on his early albums—classic, compelling songs by Freddie King, Robert Johnson, J.B. Lenoir, and other giants of the blues—and his own convincing songwriting, which always sounded authentic to the genre, was exceptional. He was also an excellent keyboardist and guitarist in his own right, and possessed a soulful, haunting tenor voice that—on a slow blues—sounded like a wraith from the lyrics of Johnson’s “Me and the Devil Blues.”
Mayall remined loyal to the genre he loved through more than 37 studio albums and 33 live recordings, including a series of archival releases featuring Clapton, Green, and Taylor over the past dozen years. By the time he was making his early recordings with those guitarists, Mayall had amassed one of the largest collections of blues recording in the U.K. which he freely shared with them along with his direct instruction in the music. Clapton described him as “having the air of a favorite schoolmaster who still manages to be cool.” That was a role Mayall relished and played his entire life.
A full-length tribute to Mayall will be published on the premierguitar.com website shortly.
