Learn how classic Fender amplifiers can be tweaked and retrofitted to give you smooth, vintage bass tones.
Those of you who have read my earlier columns know I am a diehard fan of the classic Fender tube amps, particularly the black- and silver-panel-era Fenders. They’re great tone platforms that can take you in many directions with various guitars and pedals, and they work just as well for harmonica, electric piano, and bass guitar due to their natural, straightforward tone. In this column, I’ll share my experiences and tips for running a bass through different Fender guitar amps.
Guitar amps and speaker cabinets are normally built much lighter than typical closed bass-amp cabinets. High-wattage bass amps require dense, robust construction that can handle serious air pressure. They’re often closed cabinets with air intakes called bass reflex systems, which control airflow from the speaker vibration and enhance the lower frequencies. But even without a bass reflex system, some guitar amps can produce a nice bass-guitar tone. Obviously, they’re not capable of doing what an 8x10 Ampeg cabinet can do, but for me, that’s not relevant. The music that I listen to and play (mostly ’60s and ’70s rock, soul, and blues) has a laid-back yet articulate bass tone.
I grew up listening to a lot of Donald “Duck” Dunn’s Jazz and Precision bass-guitar playing on recordings by Otis Redding, Booker T. & the M.G.’s, and other legendary artists from Stax records in the ’60s. For Dunn’s tone—which drives the groove and forms a significant part of the mix—you don’t need an extremely deep or punchy bass. With classic Fender guitar amps, you can get a mellow bass tone with medium-low frequencies that blend in smoothly with a band.
Fittingly, the first amp I’d like to mention is the Fender Bassman. The black-panel version—a 50-watt head with a diode rectifier, negative feedback loop, and dual 6L6 tubes—shouts “clean headroom.” The 2x12 speakers in the matching, closed piggy-back cabinet sound bassy and tight, and offer more low end than any of the open-back Fender amps. The amp has two channels, one voiced for bass and one for guitar. The bass channel offers a deep switch to better tune in or out the lowest frequencies, and you can unlock more tone options by installing a 25k mid switch in the normal channel, a mod I explain in my May 2023 column, “Why Did I Ever Sell These Amps?” The mid switch acts like a fat boost that can trigger the amp to distort if you play at the threshold of the amp’s breakup point.“With classic Fender guitar amps, you can get a mellow bass tone with medium-low frequencies that blend in smoothly with a band.”
Another trick I like to do is jump channels. I dial in a full, relaxed tone on the bass channel, and a brighter tone on the normal channel with the bright switch on. (Sometimes I add some overdriven tones using the mid switch and volume on the normal channel.) If you’re after more volume, consider installing louder, more efficient speakers. The original Oxford, Jensen, or Utah speakers in vintage Fender amps are modest compared to modern ceramic or Neodymium speakers, which can help lighten the heavy speaker cabinet. Plus, you can use other external speaker cabinets with the 4-ohm Bassman head for more punch and different tones. The speaker impedance should be between 2 and 8 ohms, but 4 ohms will give you the most clean headroom.
The Fender Showman and Dual Showman are two other piggy-back amps worth mentioning. Compared to the Bassman, these models have some advantages. They boast almost twice the power for bigger stages and rooms, and the Dual Showman’s flexible impedance allows you to use a variety of speaker cabinets. (I prefer 10" and 12" speakers over the original 15" Showman ones for their faster response and lighter weight.) That said, they lack the Bassman’s deep switch, dedicated bass channel, and ability to jump channels.
Finally, we have the Tweed Bassman and the Super Reverb. By specs alone, the black-panel Super Reverb is the heir of the narrow-panel Tweed Bassman. Both have open-back 4x10 cabinets and a 40-watt, dual 6L6 power amp section in push/pull configuration. With four 10" speakers working together, the cabinet doesn’t necessarily need to be enclosed to achieve a nice bass tone. These amps will work well for bass guitar in practice and in smaller settings, but be careful with older 10" speakers. The dry, porous paper speaker cone and thin copper wires can easily be damaged at higher volumes, so for bass usage, I’d recommend replacing them with newer speakers. Since I use my amps for both guitar and bass, I like regular guitar-voiced speakers, but if you’re using the amp exclusively for bass, you might consider using bass-specific speakers.- Fender Bassman TV Fifteen Combo Amp Review ›

“Practice Loud”! How Duane Denison Preps for a New Jesus Lizard Record
After 26 years, the seminal noisy rockers return to the studio to create Rack, a master class of pummeling, machine-like grooves, raving vocals, and knotty, dissonant, and incisive guitar mayhem.
The last time the Jesus Lizard released an album, the world was different. The year was 1998: Most people counted themselves lucky to have a cell phone, Seinfeld finished its final season, Total Request Live was just hitting MTV, and among the year’s No. 1 albums were Dave Matthews Band’s Before These Crowded Streets, Beastie Boys’ Hello Nasty, The Miseducation of Lauryn Hill, Korn’s Follow the Leader, and the Armageddonsoundtrack. These were the early days of mp3 culture—Napster didn’t come along until 1999—so if you wanted to hear those albums, you’d have to go to the store and buy a copy.
The Jesus Lizard’s sixth album, Blue, served as the band’s final statement from the frontlines of noisy rock for the next 26 years. By the time of their dissolution in 1999, they’d earned a reputation for extreme performances chock full of hard-hitting, machine-like grooves delivered by bassist David Wm. Sims and, at their conclusion, drummer Mac McNeilly, at times aided and at other times punctured by the frontline of guitarist Duane Denison’s incisive, dissonant riffing, and presided over by the cantankerous howl of vocalist David Yow. In the years since, performative, thrilling bands such as Pissed Jeans, METZ, and Idles have built upon the Lizard’s musical foundation.
Denison has kept himself plenty busy over the last couple decades, forming the avant-rock supergroup Tomahawk—with vocalist Mike Patton, bassist Trevor Dunn (both from Mr. Bungle), and drummer John Stanier of Helmet—and alongside various other projects including Th’ Legendary Shack Shakers and Hank Williams III. The Jesus Lizard eventually reunited, but until now have only celebrated their catalog, never releasing new jams.

Back in 2018, Denison, hanging in a hotel room with Yow, played a riff on his unplugged electric guitar that caught the singer’s ear. That song, called “West Side,” will remain unreleased for now, but Denison explains: “He said, ‘Wow, that’s really good. What is that?’ And I said, ‘It’s just some new thing. Why don’t we do an album?’” From those unassuming beginnings, the Jesus Lizard’s creative juices started flowing.
So, how does a band—especially one who so indelibly captured the ineffable energy of live rock performance—prepare to get a new record together 26 years after their last? Back in their earlier days, the members all lived together in a band house, collectively tending to the creative fire when inspiration struck. All these years later, they reside in different cities, so their process requires sending files back and forth and only meeting up for occasional demo sessions over the course of “three or four years.”
“When the time comes to get more in performance mode, I have a practice space. I go there by myself and crank it up. I turn that amp up and turn the metronome up and play loud.” —Duane Denison
the Jesus Lizard "Alexis Feels Sick"
Distance creates an obstacle to striking while the proverbial iron is hot, but Denison has a method to keep things energized: “Practice loud.” The guitarist professes the importance of practice, in general, and especially with a metronome. “We keep very detailed records of what the beats per minute of these songs are,” he explains. “To me, the way to do it is to run it to a Bluetooth speaker and crank it, and then crank your amp. I play a little at home, but when the time comes to get more in performance mode, I have a practice space. I go there by myself and crank it up. I turn that amp up and turn the metronome up and play loud.”
It’s a proven solution. On Rack—recorded at Patrick Carney’s Audio Eagle studio with producer Paul Allen—the band sound as vigorous as ever, proving they’ve not only remained in step with their younger selves, but they may have surpassed it with faders cranked. “Duane’s approach, both as a guitarist and writer, has an angular and menacing fingerprint that is his own unique style,” explains Allen. “The conviction in his playing that he is known for from his recordings in the ’80s and ’90s is still 100-percent intact and still driving full throttle today.”
“I try to be really, really precise,” he says. “I think we all do when it comes to the basic tracks, especially the rhythm parts. The band has always been this machine-like thing.” Together, they build a tension with Yow’s careening voice. “The vocals tend to be all over the place—in and out of tune, in and out of time,” he points out. “You’ve got this very free thing moving around in the foreground, and then you’ve got this very precise, detailed band playing behind it. That’s why it works.”
Before Rack, the Jesus Lizard hadn’t released a new record since 1998’s Blue.
Denison’s guitar also serves as the foreground foil to Yow’s unhinged raving, as on “Alexis Feels Sick,” where they form a demented harmony, or on the midnight creep of “What If,” where his vibrato-laden melodies bolster the singer’s unsettled, maniacal display. As precise as his riffs might be, his playing doesn’t stay strictly on the grid. On the slow, skulking “Armistice Day,” his percussive chording goes off the rails, giving way to a solo that slices that groove like a chef’s knife through warm butter as he reorganizes rock ’n’ roll histrionics into his own cut-up vocabulary.
“During recording sessions, his first solo takes are usually what we decide to keep,” explains Allen. “Listen to Duane’s guitar solos on Jack White’s ‘Morning, Noon, and Night,’ Tomahawk’s ‘Fatback,’ and ‘Grind’ off Rack. There’s a common ‘contained chaos’ thread among them that sounds like a harmonic Rubik’s cube that could only be solved by Duane.”
“Duane’s approach, both as a guitarist and writer, has an angular and menacing fingerprint that is his own unique style.” —Rack producer Paul Allen
To encapsulate just the right amount of intensity, “I don’t over practice everything,” the guitarist says. Instead, once he’s created a part, “I set it aside and don’t wear it out.” On Rack, it’s obvious not a single kilowatt of musical energy was lost in the rehearsal process.
Denison issues his noisy masterclass with assertive, overdriven tones supporting his dissonant voicings like barbed wire on top of an electric fence. The occasional application of slapback delay adds a threatening aura to his exacting riffage. His tones were just as carefully crafted as the parts he plays, and he relied mostly on his signature Electrical Guitar Company Chessie for the sessions, though a Fender Uptown Strat also appears, as well as a Taylor T5Z, which he chose for its “cleaner, hyper-articulated sound” on “Swan the Dog.” Though he’s been spotted at recent Jesus Lizard shows with a brand-new Powers Electric—he points out he played a demo model and says, “I just couldn’t let go of it,” so he ordered his own—that wasn’t until tracking was complete.

He ran through various amps—Marshalls, a Fender Bassman, two Fender Super-Sonic combos, and a Hiwatt Little J—at Audio Eagle. Live, if he’s not on backline gear, you’ll catch him mostly using 60-watt Blackstar HT Stage 60s loaded with Celestion Neo Creambacks. And while some boxes were stomped, he got most of his effects from a Line 6 Helix. “All of those sounds [in the Helix] are modeled on analog sounds, and you can tweak them endlessly,” he explains. “It’s just so practical and easy.”
The tools have only changed slightly since the band’s earlier days, when he favored Travis Beans and Hiwatts. Though he’s started to prefer higher gain sounds, Allen points out that “his guitar sound has always had teeth with a slightly bright sheen, and still does.”
“Honestly, I don’t think my tone has changed much over the past 30-something years,” Denison says. “I tend to favor a brighter, sharper sound with articulation. Someone sent me a video I had never seen of myself playing in the ’80s. I had a band called Cargo Cult in Austin, Texas. What struck me about it is it didn’t sound terribly different than what I sound like right now as far as the guitar sound and the approach. I don’t know what that tells you—I’m consistent?”

The Australian-American country music icon has been around the world with his music. What still excites him about the guitar?
Keith Urban has spent decades traveling the world and topping global country-music charts, and on this episode of Wong Notes, the country-guitar hero tells host Cory Wong how he conquered the world—and what keeps him chasing new sounds on his 6-string via a new record, High, which releases on September 20.
Urban came up as guitarist and singer at the same time, and he details how his playing and singing have always worked as a duet in service of the song: “When I stop singing, [my guitar] wants to say something, and he says it in a different way.” Those traits served him well when he made his move into the American music industry, a story that begins in part with a fateful meeting with a 6-string banjo in a Nashville music store in 1995.
It’s a different world for working musicians now, and Urban weighs in on the state of radio, social media, and podcasts for modern guitarists, but he still believes in word-of-mouth over the algorithm when it comes to discovering exciting new players.
And in case you didn’t know, Keith Urban is a total gearhead. He shares his essential budget stomps and admits he’s a pedal hound, chasing new sounds week in and week out, but what role does new gear play in his routine? Urban puts it simply: “I’m not chasing tone, I’m pursuing inspiration.”
