Welcome to the tube zoo, where you’ll get to know about the nature and habits of output and preamp tubes. And how they perform in the wilds of amplification—and in your own amp.
Of all the tonally tweakable elements in the extensive chain of components that define your sound as a guitarist, the tubes tucked into your amplifier might be the most enigmatic. Working symbiotically with the circuits and transformers housed alongside them, these tubes help to determine the way your playing is translated, from the signal produced at the guitar’s pickups to the sound waves ultimately pumped into the air by the speaker and broadcast to listeners’ ears. Given their role in the signal chain, tubes can greatly influence the feel of your playing, as well as the sound.
Alternative guitar amp options have threatened to bury tubes for six decades—since the arrival of solid-state amps in the 1960s to the proliferation for modeling amps in recent years. Yet the rumors of the tube amp’s death have been greatly exaggerated, and they continue to be used by more pro and hobby players around the world than any other type of amplifier. Even the sounds of modeling rigs are based on the tone and playing feel of myriad classic tube circuits.
Didacts will occasionally argue that tubes themselves don’t have a sound. Certainly, that’s true as far as the silence you’ll hear if you unplug a tube and hold it up to your ear. So, sure, the design and circuit of the amp in which any tube is used sets the foundation of its overall tone. But tubes do very much enhance or define certain sonic characteristics of amps, which is something you discover pretty quickly when you swap one tube type for another (in amps that allow this)—only to discover a distinct shift in your amp’s tonal personality.
“A survey of many classic and boutique amps usually reveals specific tube types enhancing distinct sonic characteristics time and again.”
It’s probably best, therefore, to think of many classic amps and traditional tube types as working hand-in-hand to present familiar sonic templates. For that reason, throughout this guide we’ll nod to a handful of familiar amplifier makes and models when referencing many tubes—and output tubes in particular, since the most common preamp tubes are often interchangeable between drastically different amp designs.
Also, while it might be true that a good amp designer can coax nearly any tone out of any conventional type of output tube, a survey of many classic and boutique amps usually reveals specific tube types enhancing distinct sonic characteristics time and again. For example, Dick Denney might have built the most famous iterations of the Vox AC15 and AC30 around EL84s, because they were plentiful and affordable, but now that those sounds have been blueprinted, we know which tubes to turn to for consistently achieving them.
Let’s start our guide with a look at the main output tube types used in guitar amps, then we’ll move on to common preamp tubes. Per-tube prices quoted are for current or recently manufactured examples made in Russia, Eastern Europe, and China, as surveyed at reputable dealers such as Mojotone, Antique Electronic Supply, Sweetwater, Telefunken, the Tube Doctor, EHX, and the Tube Store. Tags for special or limited versions of tubes are typically a little higher.
Output Tubes
Output tubes (also called power tubes) are the larger of the tube types within your amp and are usually found toward the opposite end of the chassis from the amp’s input. These tubes receive the guitar signal that the preamp tubes have already amplified slightly and amplify it much more, into a signal that can be pumped through a speaker via an output transformer. Let’s take a family-by-family look at these tubes
6L6 Types
Tone Template: Big American
Price: $25 to $50 street

Used in pairs for 35 to 50 watts or quads for 80 to 100 watts, 6L6s are the classic big American tube, probably best defined by the sound of the larger, legendary Fender amps of the ’50s and ’60s: the tweed Bassman, the black-panel Twin Reverb, the Super Reverb, and more. This tube has a bold, solid voice with firm lows and prominent highs. The sound can almost be strident in loud, clean amps that were designed for maximum headroom, or silkier and more rounded in smaller amps—like many of the tweed era—that allow for easier and earlier clipping.
Different 6L6s offer varying types of tonal performance. The 6L6GB and 6L6GC, for example, are a little softer/rounder and firmer/bolder, respectively, while the latter is also capable of handling higher voltages and delivers later breakup with increased headroom. (Note: These aren’t better/best distinctions. Either tube may be preferable according to your sonic needs, or might be required by your amp’s specifications.) A “W” designation on either of these denotes a more rugged tube originally intended for military use.
“6L6s are the classic big American tube, probably best defined by the sound of the larger, legendary Fender amps of the ’50s and ’60s.”
The original 5881 tubes manufactured in the U.S. in the ’50s and ’60s are a tougher sibling of the 6L6. They put out a little less power and break up a little earlier than the 6L6GC. Currently manufactured 5881s, however, are usually 6L6 types that have been relabeled, and therefore don’t vary greatly in their characteristics. If you’re lucky, you might find some new old stock (NOS) originals (see sidebar at bottom of page).
In many amps, all of the tubes mentioned in this 6L6 section can be swapped for each other, with some caveats. Always refer to your amp manufacturer’s instructions before doing so, and be aware that higher-powered amps designed with 6L6GCs in mind might run at voltages too high for 6L6GBs or 5881s.
For a further sonic reference point, 6L6 types also appear in many vintage Gibson, Silvertone, Danelectro, and Valco amps, plus early Marshall JTM45s, many Mesa/Boogie Mark Series models, Dumbles, many powerful Soldano and Bogner amps, and boutique favorites like the Carr Rambler and Dr. Z Z-28 MkII.
EL34s
Tone Template: British Stack
Price: $23 to $50 street

EL34s, used in pairs for 45 to 60 watts or quads for 100 to 120 watts, are responsible for the archetypal 50- and 100-watt tone from across the Atlantic, as delivered by the classic Marshall plexi variations. It is characteristically thick and mid-forward, with round lows, crispy highs, and a slightly granular texture overall—and smoothly compressed and aggressive when driven hard. The EL34 can also deliver tighter and bone-crunchingly punchy sounds to arena-rock stages in amps that can be pushed up to 120 watts with sets of four tubes, such as the Hiwatt DR103. That’s thanks to this tube’s ability to handle very high plate voltages.
The EL34 is featured in post-1967 Marshalls like the JMP50 and JMP100 plexi and metal-panel amps, later Master Model 2203s and 2204s, JCM800s, and the majority of modern models. These tubes are also used by (as mentioned) Hiwatt, Orange, and Sound City, and in Vox’s AC50 and AC100, as well as several amps from Selmer and Traynor. Contemporary makers seeking that Brit-stack kerrang! at full volume usually turn to EL34s, so they are also part of the formulation of high-gain-design builds from Rivera, Bogner, Friedman, and Mesa/Boogie, as well as the Matchless Clubman, TopHat Emplexador, and Komet K60.
KT66s
Tone Template: Bold British
Price: $45 to $70 street

This large, imposing Coke-bottle of a tube was Britain’s response to the American 6L6. As such, it has broadly similar characteristics and produces roughly the same wattage in pairs and quads, although it can handle higher voltages and adds its own sonic personality to the brew. Given this, the KT66 can be used in place of 6L6GCs in many amps, although you should check your manufacturer’s guidelines just to be safe.
The KT66 is probably best known, in vintage amps, for its use in many Marshall JTM45s of the early ’60s, which started with 6L6s and 5881s (following their inspiration of Fender’s tweed Bassman circuit) before moving to the British-made tube when the American “valves,” as the Brits call tubes, became scarce in the U.K. In recent decades, the KT66 has been rediscovered by many boutique amp makers. It’s the tube of choice for the Dr. Z Route 66 and the original single-ended Carr Mercury, among others. Along with its good balance and clarity throughout the frequency range, the KT66 generally offers a slightly bolder low end than the 6L6, and what some players hear as a sweeter, juicier midrange response—making it something of a good blend of the 6L6GC and the EL34.
6550s and KT88s
Tone Template: Punchy, Powerful, and Surprisingly Versatile
Price: $50 to $80 street

A big, powerful tube capable of producing massive wattage in the right circuit, the 6550 has also been used somewhat against type by a surprising number of creative boutique amp makers. In the late ’60s and ’70s, the 6550 was more likely to be found in bass amps—six of them created the original Ampeg SVT’s stadium-rumbling tones—but was also used, for a time, in Marshall guitar amps exported to the U.S. because its ruggedness and greater availability eased servicing issues.
Sonically, the 6550 is bold, clear, tight, and well-composed, with very little compression when pushed, but an aggressive, muscular crunch when it does begin to break up. Some makers—George Alessandro, for one—have cleverly used it to achieve more nuanced tones, but usually it’s a tube that’s employed when massive wattage is the ultimate goal.

Although not identical to the 6550, the KT88 is a common substitute that presents many of the same characteristics. Sonically, it leans somewhere between the 6550 and EL34, but with the tighter low end and massive output of the former. It can usually be swapped directly for a 6550, and often for an EL34, with some slight modifications (as ever, consult your manufacturer or a good amp tech). The mighty 200-watt Marshall Major is the best vintage reference point for this output tube, but it has also been used more recently in the RedPlate BluesMachine and Fryette Sig:X, among others—generally amps seeking either high headroom or a greater proportion of preamp-tube overdrive to output-tube distortion.
“If you’re curious about the sonic effects of variations in 12AX7s that can be used in your amp, it’s worth trying a few to check out the phenomenon for yourself.”
6V6GTs
Tone Template: Juicy, Smaller American
Price: $22 to $55 per tube
Courtesy of Telefunken
Originally an American-made tube (though later produced elsewhere), the 6V6 is often thought of as the little brother of the 6L6. But, despite its use in the smaller- to medium-sized amps made by golden-age American companies of the ’50s and ’60s—who used 6L6s in their larger amps, it really has a sonic signature all its own. A pair will generate around 15 to 18 watts in a cathode-biased amp (think tweed Deluxe) or upwards of 22 watts in a fixed-bias circuit (Deluxe Reverb), and they were also sometimes used in quads to produce 30 to 50 watts. Their sonic personality? Round, rich cleans and a juicy, relatively mid-forward sound when pushed into distortion, with notable compression and a hint of granularity at the core.
In addition to the notable Fender models the 6V6 appeared in, these tubes were also deployed in the most popular Gibson amps of the ’50s and have been used in near-countless reissue and boutique models over the past couple of decades. The Tone King Imperial, Bogner Goldfinger 45, Carr Mercury V and Skylark, Divided By 13 CJ 11, and Victoria Silver Sonic all used 6V6s in their output stages.
EL84
Tone Template: British Chime
Price: $17 to $38 per tube
Courtesy of Electro-Harmonix
In something of a parallel to the American 6V6, the EL84 (originally a British and European tube) is often talked of as a “junior EL34,” although, again, it has a personality very much its own. This tube is notable for being the only 9-pin (noval) tube in our selection (most tubes are octal, having 8 pins), and it can look much like a taller preamp tube. The EL84 delivers around 15 to 18 watts in pairs, or from 30 to 36 watts in quads.
Far and away most famous for its use in the Vox AC15 and AC30, the EL84 is known for its sweet, bright, chimey clean tones and succulent, textured, harmonically saturated overdrive. “Shimmer” and “bloom” are among the adjectives players use to describe EL84s in the sweet spot, just at the edge of breakup. In addition to the archetypal original Vox amps and later reissues, the EL84 has been popular with a long list of other companies, including boutique builders who clearly take their inspiration from the British classics.
Popular amps like the Matchless Lightning, Spitfire and DC-30; Dr. Z Carmen Ghia and Maz (the latter has two equivalent 6N14Ns power tubes); 65amps London and Soho; TopHat Club Royale; Friedman JJ Junior; Mesa/Boogie Mark Five: 25 and 35; and Fender Blues Junior and Pro Junior all use this tube.
Preamp Tubes
Generally speaking, preamp tubes are less likely to define the foundational sound of any given amplifier, although swapping one for another—even of the same type, but a variation or a tube from a different maker—can still impose a noticeable change on your tone. One reason we think of preamp tubes as less of a defining element in most guitar amps is because the vast majority of amps use the same preamp tube types. The 12AX7 is far and away the most common preamp tube and has been since the early ’50s. Again, variations on makes of 12AX7s can still stamp elements of their own personality on the sound of any amp, and swapping one manufacturer’s 12AX7 for another might produce dramatic sonic changes, but not the same sort of tectonic shift in the basic characteristics of any given amp as output tubes.
If you’re curious about the sonic effects of variations in 12AX7s that can be used in your amp, it’s worth trying a few to check out the phenomenon for yourself, in order to select a favorite. Otherwise, it’s probably more informative to discuss their different levels of gain available via various preamp tubes. That will alter the sound and feel of most amps, since the proportions of clean and overdriven sound, the point on the volume control at which distortion sets in, and other gain-related factors all play a big part in shaping what we think of as our tone.
Each major type of preamp tube exhibits what we call a “gain factor,” and the relative comparison of this spec gives us some indication of how hard that tube will drive the preamp stage of any amp. To that end, despite the 12AX7’s domination of the market, let’s also look at a few other tubes, too. (Note: We’re only discussing common 9-pin (noval) preamp tubes here, but the lesser-used, octal-based preamp tubes, more common up until the early to mid-’50s, are still enjoyed by some players.)
Dual-Triode Preamp Tubes
12AX7s (aka ECC83s), 5751s, 12AT7s, 12AY7s
Price: $18 to $35
Each of these tube types contains two triode gain stages within one bottle—hence, the “dual-triode” name—and they can perform their duties in two parts of the preamp circuit simultaneously using each triode. [Each triode gain stage consists of three electrodes: a cathode filament, anode plate, and control grid. For more background, check out Dan Formosa’s article “Tube-Amp Basics for Beginners,” in the June 2021 issue, or at premierguitar.com.] In theory, any one of these tubes—listed above in descending gain levels—can be substituted for each other with little chance of damage to your amplifier. Technically, the 12AT7 is usually biased differently than the others, so might not perform optimally in a circuit set up for a 12AX7, but you’re unlikely to damage your amp by trying it out. (If you’re curious, swap it in for a short period of time, and if you like the results, check with your amp’s manufacturer or a good tech before using it full-time.)
By the way, here are the specific gain factor ratings—the measures for how much a tube amplifies the input signal—for these tubes:

12AT7: 60

12AY7: 40

The main effect of swapping between these tubes of descending gain factors will be increased headroom and a later onset of distortion as you run down through the ranks. Each comes with its own nuanced sonic characteristics, too, which are difficult to define when divorced from the specific circuit in which they are used. Note, however, that many players find the 12AT7 (most commonly seen in reverb and phase-inverter positions) to be a little dull or cold-sounding, even as compared to the lower-gain 12AY7.
The 12AY7 is notable for its use in the first gain stage of most tweed Fender amps of around 1952 to ’60. Over the years, many players have swapped these for more common 12AX7s, which delivers earlier breakup and is desirable for some playing styles. This hotter tube can lead to a somewhat “fizzier” distortion when pushed hard in this type of circuit, though, and the 12AY7 is still considered to deliver the proper tone of classics like the 5E3 Deluxe, 5F4 Super, and 5F6-A Bassman.
Pentode Preamp Tubes
EF86, 5879
Price: $35 to $200
Courtesy of The Tube Doctor
Seen far less often but still beloved by some players, the pentode preamp tube houses a single pentode gain stage within a glass envelope that’s otherwise identical to the 12AX7 and the others above. As you might guess, pentode tubes have five electrodes, with screen and suppressor grids added to the 12AX7 family’s three. These are not, however, interchangeable for dual-triode tubes, so don’t even try it!
The most common pentode preamp tube is the EF86 (aka 6267), found in the classic iteration of the early ’60s Vox AC15. This tube reputedly has an even higher gain factor than the 12AX7—although the exact number is debated—and is characterized by a fat, rich sound. It’s prone to less self-distortion than the dual-triodes, too, meaning it passes a full-frequency signal along to the next stage in the amp without adding much of its own fizz or sizzle, although it can certainly contribute to tube overdrive. It also resists collapsing into mush when hit by an overdrive pedal in front of the amp. Boutique amps that employ the EF86 include the Matchless DC-30 (in channel 2, for high gain), the Dr. Z Z-28, and the Matchless DC-30.
Another pentode tube is the American-made 5879, which has similar characteristics to the EF86, although it also has different internal pin connections and therefore cannot be used in place of it. Probably best known for its use in the Gibson GA-40 Les Paul amp of the late ’50s, this one has most notably been employed in several current models from Divided By 13.
The Skinny
Okay, now you know all the basics about tubes. Use it as you will—to experiment, to hold your own in debates with fellow gear nerds, or as another stepping stone on your path to becoming a tone sensei.
Follow Your NOS

As you get deeper into the world of replacement tubes for guitar amplifiers, and particularly if you fuel your knowledge by perusing online forums, you’re likely to come across the term “NOS” again and again, along with the recommendation that those are the tubes you need to buy. Short for “new old stock,” NOS tubes are those that were manufactured many years ago—usually during the golden age of American and European tube production—but have never been used. They are old stock, but are essentially new because they have never been installed in an amplifier.
The demise of the vacuum tube industry in the U.S. and Europe began in the late 1960s and early ’70s, when transistors took the reins for just about all amplification duties other than those of guitar amps. Production dwindled through the ’70s and all but disappeared after, although a few tubes were made in the U.S. (the 6550, in particular) in relatively small numbers right up until 1993. More to our point, though, since the early ’80s all new tubes have been manufactured in Eastern Europe and China, particularly because these regions still needed them for use in military equipment that was slower to update to new tech. It’s worth remembering that once the technology in military and consumer electronics moved forward, the guitar-amp and audiophile markets weren’t enough to sustain the tube industry.
Guitarists have been plundering whatever stocks of NOS tubes they could find for a good three decades or more. So, there aren’t a whole lot of genuine NOS tubes left, and those that remain are very expensive. Beyond this, the bigger issue with acquiring NOS tubes today revolves around quality and verification: a lot of sub-par tubes that were rejected during testing over the years have ended up being recycled as NOS, as have a lot of used tubes pulled from old amps and polished up. Buying NOS from a reputable dealer can help mitigate these issues, but, once again, you will pay a premium. For example, we recently spotted an Amperex Bugle Boy 12AX7 for sale at $349.95. Is it that much better than a JJ Electronic 12AX7 for 20 bucks?
No matter how much chat-room pundits rave that you must use NOS tubes, current (or at least recent) tubes provide good tone and excellent reliability in the vast majority of guitar amps in use today. It’s also worth considering the fact that contemporary amp makers are usually designing and fine-tuning their circuits with current-manufacture tubes in mind, so while a rare and expensive NOS substitute might get a little more out of them, that is by no means guaranteed.

Billy Corgan shining with his Reverend Z One.
The Smashing Pumpkins frontman balances a busy creative life working as a wrestling producer, café/tea company owner, and a collaborator on his forward-thinking, far-reaching line of signature guitars. Decades into his career, Corgan continues to evolve his songcraft and guitar sound for the modern era on the band’s latest, Aghori Mhori Mei.
“Form follows function,” explains Billy Corgan when asked about the evolution of his songwriting. These three words seem to serve as his creative dictum. “Early Pumpkins was more about playing in clubs and effecting a response from the live audience, because that’s where we could get attention.
When the Smashing Pumpkins formed in 1988, they were ripping in rock clubs with psychedelic-inspired sets that drew on ’60s-rock influences like Blue Cheer, Jimi Hendrix, and Led Zeppelin. But by 1992, after the breakout success of the previous year’s swirling alt-rock masterpiece, Gish, “Suddenly, we’re on a major label,” recalls Corgan. “Pearl Jam sold a gazillion records. Nirvana sold a gazillion records. Alice in Chains is selling a gazillion records. And somebody puts a finger up to my temple and says, ‘You better figure out how to write pop songs or you’re going to go back to working at a record store.’
“So, how do I translate this kind of hazy psychedelic vision into something that sounds like pop-rock radio? I’d better figure this out, and fast.” On 1993’s Siamese Dream, Corgan had obviously gone far beyond simply figuring out how to fit his vision into a radio-ready format; he’d pushed alternative rock to new heights, masterfully crafting hooks fit for the band’s unique, massive guitar-driven sound.
More than three decades later, Corgan hasn’t stopped evolving his artistry to fit the times. On the firm foundation of his extremely well-developed, instantly recognizable musical voice, he’s made his career one of the most interesting in rock music, branching out into unpredictable trajectories. In 2017, he launched a new career as a professional wrestling producer when he purchased the National Wrestling Alliance, the source of the limited TV series Billy Corgan’s Adventures in Carnyland.The Smashing Pumpkins - "Edin"
And he’s applied that knack for spectacle—a de facto pre-req for anyone in the pro wrestling biz—to the band’s social media presence. In January 2024, when guitarist Jeff Schroeder split with the Smashing Pumpkins, they turned to the internet for an open call. Not only did the band eventually find new-hire Kiki Wong, but they effectively got every guitarist on the internet dreaming about joining the Pumpkins.
Corgan has also found a creative outlet as a guitar conceptualist. His four signature Reverends—the Billy Corgan Signature, Terz, Z-One, and Drop Z—were created in collaboration with Joe Naylor, the company’s visionary builder. Taken together, these models go well beyond standard signature artist instruments protocols. Not content to just design his own dream guitar, Corgan is equally concerned with contributing to the guitar community. The Billy Corgan Signature and Z-One models are forward-thinking electric guitars well-outfitted with hip, futuristic aesthetics and custom pickups; the Terz and Drop Z break new ground in guitar design. The Terz is a 21 1/2"-scale model meant to be tuned one and a half steps up—G to G—and the Drop Z model, at 26 1/2" scale, is intended for D standard or lower tunings. In the case of these alt-tuned guitars, the instruments are specifically voiced for their tunings, with custom pickups.
“In that quiet solitude of just you and the guitar, this communication can happen that sort of expresses something about yourself that is surprising.”
With all this action—plus signature Yamaha acoustics and his Highland Park, Illinois, café, Madame Zuzu’s, which he owns with his wife, Chloé Mendel—Corgan must be dialing into a deep, super-focused state when working on music, because he’s been prolific. In 2023, the Pumpkins released the epic ATUM: A Rock Opera in Three Acts, the third part of the trilogy that began with the Pumpkins’ smash-hit Mellon Collie and the Infinite Sadnessin 1995, followed by 2000’s Machina/The Machines of God. In 2024, the band released Aghori Mhori Mei. Pitched as a stripped-down guitar record, and exempt from the former’s grandiosity, the songs are often riff-centric guitar jams, full of dark, in-your-face tones. But that pitch might belie the album’s rich compositional complexity and intense emotional breadth. Corgan’s writing on Aghori exemplifies all the nuance and finesse of his broader work, as do the dynamic, thoughtful guitar arrangements and hard-hitting performances.
With so much going on, how does Corgan keep his artistic vision focused and in step with the times? How does he find time to tap into the creative essence that has made his music so special? What drives his process? The only way to find out is from Corgan himself.
The Smashing Pumpkins’ Aghori Mhori Mei was pitched as a more stripped-down guitar record, but don’t let that description, fitting as it may be in comparison with their recent work, belie its majesty.
The premise of Aghori was to be more of a stripped-down guitar record. How did you approach this album from a compositional perspective?
Corgan: The idea was to return to the early language of the band and see if it had a modern application. If you were making a movie, it would be akin to: We’re going to shoot this on VHS cameras and edit in an old analog bay and see if you can make something that a modern audience would actually enjoy and appreciate.
The way most rock records are made these days is “in the box,” which is Pro Tools or whatever people use. You can hear that the digital technology is very important to the way modern rock music, whether it’s metal or alternative, is made. It’s become the fifth band member—you know what I’m saying? They’re able to do things and effect changes and musically innovate in a way that you wouldn’t if you were just on a floor with the band playing in a circle, like we used to. So, for us, we could continue down this digital path, and I’m not that interested in gridding out my guitars.
When you go listen to a Pumpkins record, that’s live playing. That’s not all chopped up—99% of what you hear is literally from our hands and mouths—we’ll still fly in a chorus here and there. If you’re at a particular crossroads, do you continue to move forward and with technology as your ally? Or do you kind of go back and see if that old way still has something magical about it? That becomes the sort of the existential debate of the record, both internally and publicly, which is: Is there a there, there?
But to clarify, this isn’t an analog recording.
Corgan: We record to Pro Tools. It’s using the technology of Pro Tools to make your records that we don’t do. I’m not trying to make a point. I’m saying using the technologies that are present to write your music or using it to do things that you can’t humanly do—that we don’t do.
Listen to your standard metal record. Everything is gridded to fuck: All the amps are in the box, all the drums are in the box, there’s not a missed note, everything’s tuned to fuck. You know what I mean? That’s modern metal, and I like it. It’s not like I turn up my nose at the thing, but that’s a way of making music for many people in 2024. We decided to try and go back and make a record the old-fashioned way, not to make some sort of analog point.
“There’s a certain loneliness in the way I play because I didn’t have anybody else to play guitar with.”
You write mostly on acoustic and piano. Where do the guitar arrangements come in?
Corgan: The fundamental process, going back to the beginning, is to create the basic track; the vocal then becomes the next most important thing, and then the icing on the cake is the guitar work over the top of that, basically to support and supplement the vocal and create more melodic interaction.
I got a lot of that from Queen and Boston and some Beatles—the idea that the guitar takes on a lead voice of its own that’s distinctive and almost becomes another lead singer in the band.
That stuff doesn’t show up literally until the last day working on the song. It’ll come off wrong, but we don’t spend a ton of time on it. And I don’t know what that means other than it seems to be like everything is done, and then you go, “Okay, time for the guitar work.” You’ll spend three hours, six hours just going through and trying stuff. Then it sort of just appears, and you go, “Oh, that sounds cool,” and you move on. It benefits from being fresh or feeling kind of like an emotional reaction.
I remember being in a car circa 1975 or ’76 and “Killer Queen” by Queen was on the radio. You’re listening to a song, the song sounds cool, and there’s flange vocals, and I’m 10 years old, in the backseat. All of a sudden, that lead break comes in; it’s just fucking loud. It has that feeling of somebody stepping forward into a spotlight. It’s not a show-off thing. It’s the way it makes you feel. It’s like a lighter type of moment. We’ve always chased that feeling.

Guitar starts out for so many of us as this really personal thing that we spend all our time doing, and then as life gets more complicated, you just have less time. What is your relationship with the guitar like in 2024? Do you have a day-to-day relationship with guitar playing?
Corgan: I do not. I don’t really pick up the guitar much unless I’m working.
When you do pick up the guitar, is it with intent? Do the ideas come inspired by the guitar, inspired by something you play? Or are they up in your head, and then you’re grabbing a guitar to realize it?
Corgan: If I pick up a guitar, I’m looking to play something that surprises me. It’s whatever comes out. And sometimes you hit the wrong chord and go, “Oh, that’s interesting.” Or you find a new inversion or something that you never thought of before. You try to play a different scale run than you’ve played 10,000 times, always landing on the same note. It’s just looking for something just a little bit new. I find oftentimes, in that quiet solitude of just you and the guitar, this communication can happen that sort of expresses something about yourself that is surprising—an emotional feeling or a way of approach.
“You could say to me, ‘Hey, play me some Siamese-type thing that you would’ve done in ’92,’ and in five minutes, I could write you something that would sound like a song that would’ve been a Siamese song in ’92.”
The style of my guitar playing came out of taking care of my disabled brother when I was a teenager, so I was stuck inside a lot. To paint a simple visual, imagine being stuck inside on a summer’s day and watching people play outside through the window as you’re playing the guitar. That was my life for much of my teenage years, because I was in this position where I had to look after somebody who was not so much homebound, but it wasn’t like the type of child at his stage of development that you could take him in the backyard and let him run around. You kind of had to look after him. It often became easier to stick him in front of a television or let him take a nap while you’re practicing.
There’s a certain loneliness in the way I play because I didn’t have anybody else to play guitar with. I developed a style that had a kind of call-and-response aspect to it in the open strings and the drone playing, because it was a way to effect a larger conversation without somebody else in the room.
Then, when it was James [Iha] and I in the early days of the band, James would basically do different versions of what I was playing. That created an even bigger conversation that seemed to create almost like a third guitarist. You can hear that in the whistling harmonics in the background. That’s just two guitars playing, but you create a ghost effect. I’ve done a lot of guitar work in the studio where people would be visiting me, and they look at the speakers, “What’s that sound?” And I’m like, “That’s just two guitars.” They don’t believe me. I literally have to solo the two guitars and just show them. That’s the harmonic effect.
I still have that inner relationship with my playing, where I could just sit down and play and find something that sounds like a bit of a conversation.

When you’re writing, picking up a guitar, looking for those things, like you said, are you still after the same feeling you had initially or has the feeling changed?
Corgan: I think it’s more trying to find something that seems to signify whatever’s happening at the moment. It’s a truthfulness. You could say to me, “Hey, play me some Siamese-type thing that you would’ve done in ’92,” and in five minutes, I could write you something that would sound like a song that would’ve been a Siamese song in ’92. I can dial in any era of the band or my writing at will, because they’re all based on methodologies and certain emotional templates. So, I’m trying to do that for today. What is the 2024 version of that that makes me feel something—anything at all?
There’s this other creative side to your work, which is your signature gear. You have four Reverend guitars, and they’re all very different from each other. You’ve created them with Joe Naylor. Can you tell me about that collaboration?
Corgan: Somehow, Joe is able to go back and listen to what I’m referencing, and then translate that into something that’s physically tangible and consistent.
I don’t think a gimmicky guitar serves anybody. My signature guitars need to be useful to anybody else doing their music, not just my kind of music. And I’m very proud of that. I think that’s what makes a great guitar—it has application to whoever picks it up. And a lot of credit to Reverend to be willing to take these chances that I’ve sort of set them off chasing.
The Reverend Billy Corgan Drop Z is specially voiced in feel and sound for D standard and lower tunings.
They’re all bold guitars, but especially the Terz and the Drop Z, which are built specifically for alternate tunings. What were you looking for when you came up with the idea of those instruments?
Corgan: The thing with the Terz, which is G to G as opposed to E to E—a step and a half higher—was in listening to guitarists like Jonny Greenwood of Radiohead and other guitar players of that generation, I noticed that the function of the guitar for many alternative guitar players was becoming more atmospheric and less elemental. I thought maybe they would like to have a higher tonal range to work in. Because, ultimately, in 2024 logic, you want to get the guitar away from the vocal. If you think of the classic Telecaster sound, well, if you’re playing in the key of G on a Telecaster, that sits exactly where the vocal is. It’s like the worst possible place for a guitar in the 21st century. But if you can increase the harmonic range of the guitar, it does sort of sit, elementally, a little higher.
I don’t think people have figured that out yet about that guitar. But I have a funny feeling that at some point somebody will, much like when Korn took the Steve Vai guitar and took it in a completely different direction and made a whole new genre of music with it. I think the Terz opens a player up to a different tonal range.
“I don’t think a gimmicky guitar serves anybody. My signature guitars need to be useful to anybody else doing their music, not just my kind of music.”
A lot of these modern alternative guitar players, they don’t play super complicated stuff. Whether they were inspired by Jonny from Radiohead or the guy from Coldplay, it’s more like a tweedle-y guitar, like twilight, vibey.... You look at their pedalboards; it’s a lot of reverbs and bucket delays and stuff like that. I get it.
On the Drop—on making Aghori, I found myself thinking a lot about Mick Mars’s guitar sound and where Mick’s guitar sat in Mötley Crüe. Early Mötley Crüe was basically a guitar tuned down a step. Something about the D range—you could do it on a normal guitar, but it gets a little sloppy with the tuning and certainly the intonation. So, I talked to Reverend about making a D-to-D guitar that doesn’t feel like a baritone guitar, that plays and feels very much like an E-to-E guitar, but gives you range. For a modern guitar player who wants to make music that ends up on the radio, the specificities of where that guitar needs to sit tonally and how it would be mixed is what I was thinking of.
So, these are instruments for the modern player who wants to make music that can reach people vis-à-vis what is the media these days—streaming or whatever. If you want to take an old guitar and tune it down to F and all that … I did all that crazy stuff, too. I wouldn’t discourage anybody from doing it. But these are specific instruments with a very specific purpose, primarily for recording.
On “Edin” [from Aghori Mhori Mei], well, that’s that guitar. I think in that song, it’s dropped, so the low string is a C. But you can hear how that guitar sits so forward in the track. That’s a credit to Joe making that guitar exactly what I wanted, and the pickups really doing their job with how it sits in the track.Corgan has an early memory of hearing Brian May’s lead break on “Killer Queen”: “It has that feeling of somebody stepping forward into a spotlight. It’s not a show-off thing. It’s the way it makes you feel. It’s like a lighter type of moment. We’ve always chased that feeling.”
I want to come back to how that affects your playing. You have these instruments that are now specifically voiced to your vision. When they get in your hands and you’re working on something, how do you exploit the sonics of those guitars? Maybe you wrote a song on acoustic, but now you have this instrument that you’ve helped ideate, and you can do stuff that your other guitars can’t. Where does that come in the creative process?
Corgan: I don’t think I have a romantic answer. For me, it’s more about recording accuracy or clarity. If you compare, let’s call it the “Mellon Collie ’95” guitar sound, where we were mostly a half-step down; it’s clear, but it’s very sludgy—a lot of midrange and not a lot of stuff above, say, 17k, because I was using those Lace Sensor pickups. Modern recording; everybody wants the guitar as far forward as you can get it.
These days, I’m mostly using these Carstens amps, which is a Chicago amp-maker, Brian Carstens. I used one amp that he made for me, the Grace, which he does sell, which is kind of a modern take on the Eddie Van Halen brown sound—a ton of gain, but clear. And then he has another amp called Empire, which is more for a metal player. I use that as well. And in some cases, I stack both amps on top of each other by reamping. He has another amp, called Cathedral, which is like a cross between a Fender Twin and a Hiwatt. Again, very clear.
“Modern recording; everybody wants the guitar as far forward as you can get it.”
The best way I can explain it, and this is my poor language-ing, but if I was to take a vintage Marshall plexi and a Les Paul, like a classic amazing guitar sound, and record the riff for “Edin,” and then I was to take my Reverend Drop Z run through a Carstens amp, and you listen to the two tracks, the modern stuff I’m using, the guitar is like six more feet forward in the track; the vintage stuff sounds kind of back there. You can hear it—a little gauzy, a little dark, and the modern stuff is right in your grill. It’s not harsh; it’s not overly midrange-y. It just sounds really good and present.
So that’s the key. Because I play so distinctively that I kind of sound like me whatever you put me through, my focus is more tonal and how it sits in the stereo field.
Are pedals just pragmatic means to achieve a tone? Or is there exploration involved there?
Corgan: Since Siamese Dream, where we famously used the op-amp Big Muff and EHX Micro Synth, and some MXR stuff, the main sound of the band is just crank through something. Going back to something my father told me many, many moons ago: guitar, chord, amp is the key. I worked in the studio with Tony Iommi. Those hands, a chord, an amp—and when he plays, God’s moving mountains. We get super granular when I’m in the studio; I might play a chord that’s no more than seven-feet long, anything so I can be as close to the amp as possible, so there’s the least amount of chord from the guitar to the amp.
It’s all about driving the amp and moving that air and moving those electrons in the tubes. That’s just the key for me. If there’s pedal work on any Pumpkins albums in the last 25 years, it’s for solos and little dinky things on the top. The main guitar sound is always pure power. We want as much pure power as possible.
