Click here to watch our 2-part video tutorial on replacing your amp speakers.
Analyzing every aspect of your signal chain is a common pastime of many tone-hungry guitarists. From strings and picks to pickups and stompboxes, we swap elements in and out of our rigs, guitars, and/or signal chains, hoping for some magical new combination. At the very end of the line, however, is a component that guitarists and bassists often overlook as a means of improving or altering tone—speakers. And the fact that speakers are swapped out far less than pickups, pedals, and complete amps is rather odd, considering that the speaker is the final component that physically creates our tone. Here we aim to help change that.
Perhaps one of the reasons we don’t change speakers as much as other stuff is that some of the related technical specs can be confusing—and either dangerous or damaging to our gear if we don’t get them right. Depending on the number of speakers and intended use, speaker swapping can require an understanding of phasing and impedance, as well as the relationship between series and parallel wiring. But these concepts really aren’t so complicated that they should deter us from fine-tuning the tones coming out of those paper cones.
For this demonstration, we’re installing a quartet of 25-watt, 16 Ω Celestion G12M Greenback speakers in a vintage 1968 Marshall basketweave cabinet, which we’ll configure for a 16 Ω impedance using series/parallel wiring. (To view the wiring diagram for this project, visit premierguitar.com/4x12-wiring.) We’ve chosen a 4x12 cab because it offers the most complex example of speaker replacement. For example, re-outfitting a half-stack requires dealing with impedance and matching phase, as well as exploring the classic Marshall series/parallel wiring. (In smaller projects—say, 1x12 combo—all you need to worry about is getting a speaker with the right impedance/ohm rating and connecting the wire leads in the correct polarity.) All right—let’s get to it!
Rafiq Bhatia’s guitar is a Flip Scipio Flippercaster with vintage Teisco and DeArmond pickups and has a strikingly original voice, even without effects or processing.
“Where [neuroscience and economics] intersect is the science of decision making,” explains Bhatia. Back when he was a new student at Oberlin College, “the lab that I was the most interested in being a part of was focused on decision making under various levels of risk and uncertainty, and trying to pick apart aspects of what happens in the brain before cognition kicks in. What are the precognitive aspects of decision making, and do they predict in any way the decisions that you will actually make?
“And that, I think, is part of the same underlying spirit of inquiry that making music, and especially improvised music with other people, is born of,” he continues. “You’re in these situations where there is uncertainty and there is also risk—and if there’s not enough risk, then it’s not that compelling.”
Bhatia’s latest solo release—his first in five years—is the EP Each Dream, A Melting Door, made in collaboration with pianist Chris Pattishall. The duo improvise their way through the five-track record, unwinding an extended impressionistic world wherein dreamlike piano underscores a range of guitar tones that glimmer in an abstract light. It’s clear that Bhatia has no intention of conveying a traditional sonic image of a guitar, instead preferring to manipulate the instrument as a device for painting colors of sound.

Of course, before even getting into the methods of how he achieves those sounds, Bhatia says, “I think it’s less important how I get the sounds out of the guitar than the reasons why I might choose to go looking for them. And the way I get them out of the guitar today might be drastically different than the way I get them out of the guitar tomorrow. I care deeply about the sounds that are made, but I’m so not about the perception that you have to acquire all these ‘things’ to make it.”
His prized 6-string, the Flippercaster, was designed by the reclusive-yet-storied luthier Flip Scipio, who’s built and worked on guitars and basses for Paul McCartney, Bob Dylan, Paul Simon, and many others. After coming to recognize Scipio’s trademark on builds he came across in various New York studios, Bhatia sought him out in an effort he compares to the search for the legendary swordsmith, Hattori Hanzō, in Kill Bill. “He’s the nicest dude ever; it just took me a while to find him. But if you go visit him, he’ll make you either an amazing AeroPress coffee or a mug of smoky lapsang tea and then sit and talk with you,” Bhatia adds, smiling.
The guitar is equipped with vintage Teisco and DeArmond pickups wired to a blend knob in place of a switch, which Bhatia loves. “I usually don’t want half and half; I want a little bit of one and mostly all of the other. And to me it’s very dependent on what the room sounds like and what musical context I’m in,” he explains. The Flippercaster goes into a small pedalboard, the brain of which is a custom Eventide H90. Bhatia collaborated with the pedal manufacturer on the development of the device’s design.
The duo improvise their way through the five-track record, unwinding an extended impressionistic world wherein dreamlike piano underscores a range of guitar tones that glimmer in an abstract light.
“I was really excited,” Bhatia shares. “I was like, ‘Can you make it switch other pedals in and out of the chain like one of those pedalboard controllers? And let’s say I’m using one of your reverbs, but I want to put distortion on it. Can you make it only affect the wet signal?’ I thought they’d maybe do 10 percent of what I asked, and they did basically all of it,” he concludes, laughing.
Aside from his expression and volume pedals, his pedalboard is otherwise made up of a Klon KTR and a ZVEX Fat Fuzz Factory, the latter of which he has particular fun with. “I’m very jealous of saxophone players because they have breath,” he prefaces. “But what I’ve found is that if you play in such a way where you flirt with the edge of the [Fat Fuzz Factory’s built-in] gate, you can get the ends of notes to crackle and decay, almost like when you hear a saxophone player breathe out at the end of the note.”
His pedalboard then goes through a Universal Audio Apollo Twin MkII interface, which connects to Ableton Live on his MacBook Pro. Bhatia then uses two MIDI controllers—one on the floor with a digital display, and one with knobs that he controls with his left hand—that are both color-coded to match the lanes of his session in the DAW. “I can then grab these little bits of things that I’m playing, and bring them in and out and manipulate them while I’m also playing the guitar and generating other ones. I’m excited about it because it’s a process that is helping me erase the line between what I’ve been doing on the guitar and what I’ve been doing away from the guitar. I feel like I’m getting a little bit closer to where I can play, and the sound is saying who I am.”

Filmmaker David Lynch has been a powerful influence on Bhatia—a cover of “The Voice of Love,” from Lynch’s Twin Peaks: Fire Walk with Me, appears at the end of Each Dream, A Melting Door—as have a number of hip-hop producers and jazz musicians. Bhatia shares, “If you listen to Madlib beats, sometimes he’s doing a lot and it’s a million different small elements that have been collaged together, but other times it’s just a sample that he flipped and he didn’t change anything except for the loop point. But whether it’s something he made while fussing over all these little ingredients, or it’s just something he looped, you hear two seconds of it and it’s like, ‘Oh, that’s Madlib.’”
He mentions how that effect similarly belongs to icons such as Thelonious Monk and Jimi Hendrix. “Those are all the heroes, and they say something that’s so personal and honest to who they are and their experience that right away, you just know [snaps fingers]—it’s them. To me it sounds like honesty, and it sounds like an expression in many cases of hybridity.
“I was in class in 9th grade when the planes hit the Twin Towers, and it was on our school news channel,” he continues, emphasizing the discomfort it created for him as someone of Muslim origin, which drew unwanted speculation from his non-Muslim peers. “That was the backdrop to how I got into playing the guitar and listening to music. So, when I would hear folks who seemed to be able to take all these different aspects of who they were and what their experience was and distill it into a way of communicating through sound, that was really inspiring. It just felt like therapy to engage in trying to figure out how to do that.”
For the release of his last solo album, Breaking English, Bhatia performs here with a trio, showcasing his uniquely creative approach on the instrument in a more traditional context.
Duane Betts enjoys a control set modification that was preferred by his father, the late, legendary Dickey Betts.
Guest Picker - Duane Betts
Betts’ 1961 ES-335 has its toggle and volume-dial positions switched.
A: My favorite mod is the one on my 1961 Gibson ES-335. The toggle switch and neck volume knob positions have been switched so the volume knob is more accessible for volume swells using your pinky finger. This is something my dad had done when he obtained the guitar in the ’90s as he loved using the volume swell effect.
A pedal primed for vintage fuzz sounds.
Obsession: My current obsession is this DanDrive Secret Machine fuzz that JD Simo gave me a few years ago. I don’t use fuzz often but I’ve loved it as a way to change things up and give the listener something fresh. My normal tone is very natural with the amp turned up. This is just a great fuzz tone that gives me a new angle that I really enjoy pursuing both live and in the studio.
Reader of the Month - Steve Nowicki
A: A push/pull knob for humbucker coil split. It’s a sneaky little mod I throw on my tone pots. You won’t get amazing Strat tone, but the ability to instantly swap between Les Paul chunk and Fender twang during a jam opens a ton of possibilities tonally. Plus, no extra switches or routing needed—even though it’s fun to hack guitars apart.
Obsession: The EVH 5150 Iconic EL34 amp. Owning an 80-watt half-stack in a Brooklyn apartment might be overkill, but damn this amp is awesome. It delivers insane amounts of gain and distortion, yet every little nuance of your playing comes through crystal clear. I pair it with a Bugera Power Soak so I can crank the head and get that warm “Brown Sound” tone at lower volumes.

John Bohlinger and his Lukather-ized Strat.
A: I’ve hacked up a bunch of guitars over the years, but my favorite mod remains the highly intrusive, expensive, and quixotic B-bender install. It is the equivalent of open heart surgery, and there’s no going back—but the first time you play the Clarence White “You Ain’t Goin’ Nowhere” intro right, it’s totally worth it.
John at work. When it comes to mods, he know the drill!
Obsession: I recently filmed a PG video where we swapped pickups in my ’90s Strat with an EMG Lukather set. I never thought I’d go active, but what gets me is how smoothly the volume and tone work. I’m rethinking all my gear biases. Like maybe there’s been some progress since 1957.

Let it bleed: Jon dials back the treble on his Tele.
A: Installing a treble bleed on my volume pots has changed how I play electric guitar. Previously, I never dialed back my volume knob because it dulled my sound. Now I can fine-tune loudness and gain while retaining tone—it’s a game changer. I still swap pickups and hardware, but one mod always comes first: the humble treble bleed.
Did you know both John Paul Jones and Jimmy Page played on Shirley Bassey’s iconic recording of “Goldfinger?”
Obsession: John Paul Jones. I’ve always loved his bass (and other instrumental contributions) with Led Zeppelin. But after seeing the Zep documentary [Becoming Led Zeppelin] I searched his session work from 1964–1968, which includes Shirley Bassey, Lulu, Donovan and more. What an amazingly versatile and talented artist he is!
