Fender’s Jack White Collection dropped this week, and it includes what might be the most exciting tube amp design in decades. Fender’s Stan Cotey shares some firsthand insight into this unique amp’s design.
This week, Fender and Jack White dropped a new line that spun heads across the guitar-gear universe, proving that the Third Man’s brain knows no bounds. White has been blowing minds with Third Man Hardware’s line of collaboratively conceived gear. Working with makers of all sizes, each yellow-and-black piece is as unique as White himself.
Hooking up with Fender for the Jack White Signature Collection—which includes the Signature model hot-rod Jack White TripleCaster Telecaster and the stunning Jack White TripleSonic Acoustasonic—is as big as it gets, and this week’s announcement is proportionately epic.
The all-new Jack White Pano Verb amp looks to be one of the most forward-thinking advances in tube amps we’ve seen in … well, a very long time! Although it’s roughly inspired by three vintage Fender models—a 1964 Vibroverb, a 1960 Vibrasonic, and a 1993 Vibro-King—the Pano Verb is a rare all-new design that is poised to thrill. The single-channel stereo amp delivers 70 watts of combined power and features stereo harmonic tremolo and stereo reverb circuits, with unique routing options through the hip pair of 15" and 10" speakers. If you haven’t checked out Fender’s video announcing the amp, prepare to have your mind blown by the possibilities.
“It wasn’t based on what we could or couldn’t do, or what even was or wasn’t possible. It was just what Jack was looking to accomplish.”
Fender Vice President of Research and Development Stan Cotey, who worked closely with White to develop the prototypes for the Pano Verb, says, “There were no restrictions as far as how wild something could be. It wasn’t based on what we could or couldn’t do or what even was or wasn’t possible. It was just what Jack was looking to accomplish.” Putting those goals into action was a kick for Cotey. “I love the fact that we’re still pushing the idea of vacuum tubes and that there are things remaining to be done,” he says. “And [the Pano Verb] is a really crazy thing. It’s fun when one of the larger companies tackles a big crazy thing and releases it in a bold manner.”
We rang up Cotey to get the scoop on designing the amp as we wait to get our hands on one.
Cotey calls the Pano Verb “a really crazy thing,” and says, “It’s fun when one of the larger companies tackles a big crazy thing and releases it in a bold manner.”
The Pano Verb has a refreshingly unique and adventurous set of features.
Stan Cotey: There’s two separate power amps, there’s two separate preamps, there’s a reverb circuit. There are two separate harmonic vibrato circuits. There’s two full, separate amps in it—there’s one power supply, but everything else, there’s at least two of.
There are several different kinds of stereo interaction that could happen. The harmonic vibrato could be stereo. The reverb, even though it’s a mono tank, could be steered to the speakers differently, which kind of gives a stereo-imaging thing. So, that opens up myriad possibilities for how things could work.
How involved was Jack in the design?
Cotey: He was completely hardcore. He cared in great detail, exactly down to fine decimal points, how it worked. He was very particular about the voicing. He was very particular about the features he knew. He’s pretty studio savvy, so he had a sense of routing, how he wanted the stereo interaction of the sections to work together. He very much had an idea of stereo-ness for the amp at the outset of it. He talked early on about miking both speakers and panning them—he wanted to be able to do sort of startling things with each speaker’s content.
I think my role was to take the stuff that he wanted to do and figure out how we could do it. So, the stereo-ness of the amp, the 10" speaker versus the 15" speaker, the routing stuff you could do where the reverb goes to one speaker or both, all that stuff came from Jack.
Jack’s Vibrasonic was a touchstone for the Pano Verb.
Cotey: That amp lived with me for quite a while. He knew that he liked the harmonic tremolo.
The stereo harmonic tremolo, that’s a fairly part-intensive circuit, even in a normal brown amp. In this amp, there’s two full circuits in it, so it is literally double the parts of one of the more complicated earlier ’60s amps, just for that part of the amp. I worked out how that works. That’s two harmonic tremolos that are in sync, but opposite polarity. So, when one’s going up, the other is going down, and vice versa.
Stan Cotey is Fender’s Vice President of Guitar Research and Development and worked with White to design the prototypes for the Pano Verb.
The reverb mix on the Pano Verb is rooted in some vintage designs, but it’s handled a little differently here.
Cotey: In the video, he talked about the reverb tank in front of the amp, which forms the Vibro-King, and that he liked the idea. I think he liked the idea of having a more comprehensive, dedicated reverb circuit in an amp, not where it’s just kind of spread on the top, like margarine or something.
In a traditional Fender amp, there’s a feed that comes off the preamp circuit that goes to a driver, which is a tube and a little transformer, and that drives the reverb tank. Then, the output of the reverb tank goes into a recovery amp, a little gain stage with a tube, and that gets mixed with the output of the channel and shoved into the power amp. So, the reverb kind of occurs between the preamp and the power amp. It largely takes the tonality of the preamp on because the tone controls are upstream of it.
Jack has an old Fender amp from the early ’60s that had reverb added. I don’t know who modified it, but they actually used the second channel of the amp as the reverb return, which I think is really super clever. Then you get tone controls for the reverb. So that’s where that idea came from. He didn’t necessarily want the reverb circuit in front. He liked it between the preamp and the power amp, but he wanted to have it be more comprehensive than what would be on a typical mid-’60s Fender amplifier.
What was the most exciting feature for you to create?
The stereo harmonic tremolo was really fun, and the journey that we went on to get there was really cool. I have a tweed amp from the late ’50s from Guild that has tremolo in it, and it’s a stereo amp. It has two separate everythings. The tremolo only works on one side, and that gives the apparent sound that it’s kind of going back and forth between the speakers. We tried having just the harmonic tremolo on one side of this, and it really wanted to have two complete full circuits. So that was one of the changes that got made.
Getting the power amps to work well together was fun too. That was more about transformer and tube selection and working the power supply parts out, getting the amps where they would distort in the right way at the right times or right level. But the harmonic tremolo was definitely the elephant dancing on the bucket with the streamers going off.

Get back to center in musical and ear-catching ways.
A turnaround chord progression has one mission: It allows the music to continue seamlessly back to the beginning of the form while reinforcing the key center in a musically interesting way. Consider the last four measures of a 12-bar blues in F, where the bare-bones harmony would be C7-Bb7-F7-F7 (one chord per measure). With no turn around in the last two measures, you would go back to the top of the form, landing on another F7. That’s a lot of F7, both at the end of the form, and then again in the first four bars of the blues. Without a turnaround, you run the risk of obscuring the form of the song. It would be like writing a novel without using paragraphs or punctuation.
The most common turnaround is the I-VI-ii-V chord progression, which can be applied to the end of the blues and is frequently used when playing jazz standards. Our first four turnarounds are based on this chord progression. Furthermore, by using substitutions and chord quality changes, you get more mileage out of the I-VI-ii-V without changing the basic functionality of the turnaround itself. The second group of four turnarounds features unique progressions that have been borrowed from songs or were created from a theoretical idea.
In each example, I added extensions and alterations to each chord and stayed away from the pure R-3-5-7 voicings. This will give each chord sequence more color and interesting voice leading. Each turnaround has a companion solo line that reflects the sound of the changes. Shell voicings (root, 3rd, 7th) are played underneath so that the line carries the sound of the written chord changes, making it easier to hear the sound of the extensions and alterations. All examples are in the key of C. Let’s hit it.
The first turnaround is the tried and true I-VI-ii-V progression, played as Cmaj7-A7-Dm7-G7. Ex. 1 begins with C6/9, to A7(#5), to Dm9, to G7(#5), and resolves to Cmaj7(#11). By using these extensions and alterations, I get a smoother, mostly chromatic melodic line at the top of the chord progression.
Ex. 2 shows one possible line that you can create. As for scale choices, I used C major pentatonic over C6/9, A whole tone for A7(#5), D Dorian for Dm9, G whole tone for G7(#5), and C Lydian for Cmaj7(#11) to get a more modern sound.
The next turnaround is the iii-VI-ii-V progression, played as Em7-A7-Dm7-G7 where the Em7 is substituted for Cmaj7. The more elaborate version in Ex. 3 shows Em9 to A7(#9)/C#, to Dm6/9, to G9/B, resolving to Cmaj7(add6). A common way to substitute chords is to use the diatonic chord that is a 3rd above the written chord. So, to sub out the I chord (Cmaj7) you would use the iii chord (Em7). By spelling Cmaj7 = C-E-G-B and Em7 = E-G-B-D, you can see that these two chords have three notes in common, and will sound similar over the fundamental bass note, C. The dominant 7ths are in first inversion, but serve the same function while having a more interesting bass line.
The line in Ex. 4 uses E Dorian over Em9, A half-whole diminished over A7(#9)/C#, D Dorian over Dm6/9, G Mixolydian over G9/B, and C major pentatonic over Cmaj7(add6). The chord qualities we deal with most are major 7, dominant 7, and minor 7. A quality change is just that… changing the quality of the written chord to another one. You could take a major 7 and change it to a dominant 7, or even a minor 7. Hence the III-VI-II-V turnaround, where the III and the VI have both been changed to a dominant 7, and the basic changes would be E7-A7-D7-G7.
See Ex. 5, where E7(b9) moves to A7(#11), to D7(#9) to G7(#5) to Cmaj9. My scale choices for the line in Ex. 6 are E half-whole diminished over E7(#9), A Lydian Dominant for A7(#11), D half-whole diminished for D7(#9), G whole tone for G7(#5), and C Ionian for Cmaj9.
Ex. 7 is last example in the I-VI-ii-V category. Here, the VI and V are replaced with their tritone substitutes. Specifically, A7 is replaced with Eb7, and G7 is replaced with Db7, and the basic progression becomes Cmaj7-Eb7-Dm7-Db7. Instead of altering the tritone subs, I used a suspended 4th sound that helped to achieve a diatonic, step-wise melody in the top voice of the chord progression.
The usual scales can be found an Ex. 8, where are use a C major pentatonic over C6/9, Eb Mixolydian over Eb7sus4, D Dorian over Dm11, Db Mixolydian over Db7sus4, and once again, C Lydian over Cmaj7(#11). You might notice that the shapes created by the two Mixolydian modes look eerily similar to minor pentatonic shapes. That is by design, since a Bb minor pentatonic contains the notes of an Eb7sus4 chord. Similarly, you would use an Ab minor pentatonic for Db7sus4.
The next four turnarounds are not based on the I-VI-ii-V chord progression, but have been adapted from other songs or theoretical ideas. Ex. 9 is called the “Backdoor” turnaround, and uses a iv-bVII-I chord progression, played as Fm7-Bb7-Cmaj7. In order to keep the two-bar phrase intact, a full measure of C precedes the actual turnaround. I was able to compose a descending whole-step melodic line in the top voice by using Cmaj13 and Cadd9/E in the first bar, Fm6 and Ab/Bb in the second bar, and then resolving to G/C. The slash chords have a more open sound, and are being used as substitutes for the original changes. They have the same function, and they share notes with their full 7th chord counterparts.
Creating the line in Ex. 10 is no more complicated than the other examples since the function of the chords determines which mode or scale to use. The first measure employs the C Ionian mode over the two Cmaj chord sounds. F Dorian is used over Fm6 in bar two. Since Ab/Bb is a substitute for Bb7, I used Bb Mixolydian. In the last measure, C Ionian is used over the top of G/C.
The progression in Ex. 11 is the called the “Lady Bird” turnaround because it is lifted verbatim from the Tadd Dameron song of the same name. It is a I-bIII-bVI-bII chord progression usually played as Cmaj7-Eb7-Abmaj7-Db7. Depending on the recording or the book that you check out, there are slight variations in the last chord but Db7 seems to be the most used. Dressing up this progression, I started with a different G/C voicing, to Eb9(#11), to Eb/Ab (subbing for Abmaj7), to Db9(#11), resolving to C(add#11). In this example, the slash chords are functioning as major seventh chords.
As a result, my scale choices for the line in Ex. 12 are C Ionian over G/C, Eb Lydian Dominant over Eb9(#11), Ab Ionian over Eb/Ab, Db Lydian Dominant over Db9(#11), and C Lydian over C(add#11).
The progression in Ex. 13 is called an “equal interval” turnaround, where the interval between the chords is the same in each measure. Here, the interval is a descending major 3rd that creates a I-bVI-IV-bII sequence, played as Cmaj7-Abmaj7-Fmaj7-Dbmaj7, and will resolve a half-step down to Cmaj7 at the top of the form. Since the interval structure and chord type is the same in both measures, it’s easy to plane sets of voicings up or down the neck. I chose to plane up the neck by using G/C to Abmaj13, then C/F to Dbmaj13, resolving on Cmaj7/E.
The line in Ex. 14 was composed by using the notes of the triad for the slash chord and the Lydian mode for the maj13 chords. For G/C, the notes of the G triad (G-B-D) were used to get an angular line that moves to Ab Lydian over Abmaj13. In the next measure, C/F is represented by the notes of the C triad (C-E-G) along with the root note, F. Db Lydian was used over Dbmaj13, finally resolving to C Ionian over Cmaj7/E. Since this chord progression is not considered “functional” and all the chord sounds are essentially the same, you could use Lydian over each chord as a way to tie the sound of the line together. So, use C Lydian, Ab Lydian, F Lydian, Db Lydian, resolving back to C Lydian.
The last example is the “Radiohead” turnaround since it is based off the chord progression from their song “Creep.” This would be a I-III-IV-iv progression, and played Cmaj7-E7-Fmaj7-Fm7. Dressing this one up, I use a couple of voicings that had an hourglass shape, where close intervals were in the middle of the stack.
In Ex. 15 C6/9 moves to E7(#5), then to Fmaj13, to Fm6 and resolving to G/C. Another potential name for the Fmaj13 would be Fmaj7(add6) since the note D is within the first octave. This chord would function the same way, regardless of which name you used.
Soloing over this progression in Ex. 16, I used the C major pentatonic over C6/9, E whole tone over E7(#5), F Lydian over Fmaj13, and F Dorian over Fm6. Again, for G/C, the notes of the G triad were used with the note E, the 3rd of a Cmaj7 chord.
The main thing to remember about the I-VI-ii-V turnaround is that it is very adaptable. If you learn how to use extensions and alterations, chord substitutions, and quality changes, you can create some fairly unique chord progressions. It may seem like there are many different turnarounds, but they’re really just an adaptation of the basic I-VI-ii-V progression.
Regarding other types of turnarounds, see if you can steal a short chord progression from a pop tune and make it work. Or, experiment with other types of intervals that would move the chord changes further apart, or even closer together. Could you create a turnaround that uses all minor seventh chords? There are plenty of crazy ideas out there to work with, and if it sounds good to you, use it!
Many listeners and musicians can tell if a bass player is really a guitarist in disguise. Here’s how you can brush up on your bass chops.
Was bass your first instrument, or did you start out on guitar? Some of the world’s best bass players started off as guitar players, sometimes by chance. When Stuart Sutcliffe—originally a guitarist himself—left the Beatles in 1961, bass duties fell to rhythm guitarist Paul McCartney, who fully adopted the role and soon became one of the undeniable bass greats.
Since there are so many more guitarists than bassists—think of it as a supply and demand issue—odds are that if you’re a guitarist, you’ve at least dabbled in bass or have picked up the instrument to fill in or facilitate a home recording.
But there’s a difference between a guitarist who plays bass and one who becomes a bass player. Part of what’s different is how you approach the music, but part of it is attitude.
Many listeners and musicians can tell if a bass player is really a guitarist in disguise. They simply play differently than someone who spends most of their musical time embodying the low end. But if you’re really trying to put down some bass, you don’t want to sound like a bass tourist. Real bassists think differently about the rhythm, the groove, and the harmony happening in each moment.
And who knows … if you, as a guitarist, thoroughly adopt the bassist mindset, you might just find your true calling on the mightiest of instruments. Now, I’m not exactly recruiting, but if you have the interest, the aptitude, and—perhaps most of all—the necessity, here are some ways you can be less like a guitarist who plays bass, and more like a bona fide bass player.
Start by playing fewer notes. Yes, everybody can see that you’ve practiced your scales. But at least until you get locked in rhythmically, use your ears more than your fingers and get a sense of how your bass parts mesh with the other musical elements. You are the glue that holds everything together. Recognize that you’re at the intersection of rhythm and harmony, and you’ll realize foundation beats flash every time.“If Larry Graham, one of the baddest bassists there has ever been, could stick to the same note throughout Sly & the Family Stone’s ‘Everyday People,’ then you too can deliver a repetitive figure when it’s called for.”
Focus on that kick drum. Make sure you’re locked in with the drummer. That doesn’t mean you have to play a note with every kick, but there should be some synchronicity. You and the drummer should be working together to create the rhythmic drive. Laying down a solid bass line is no time for expressive rubato phrasing. Lock it up—and have fun with it.
Don’t sleep on the snare. What does it feel like to leave a perfect hole for the snare drum’s hits on two and four? What if you just leave space for half of them? Try locking the ends of your notes to the snare’s backbeat. This is just one of the ways to create a rhythmic feel together with the drummer, so you produce a pocket that everyone else can groove to.
Relish your newfound harmonic power. Move that major chord root down a third, and now you have a minor 7 chord. Play the fifth under a IV chord and you have a IV/V (“four over five,” which fancy folks sometimes call an 11 chord). The point is to realize that the bottom note defines the harmony. Sting put it like this: “It’s not a C chord until I play a C. You can change harmony very subtly but very effectively as a bass player. That’s one of the great privileges of our role and why I love playing bass. I enjoy the sound of it, I enjoy its harmonic power, and it’s a sort of subtle heroism.”
Embrace the ostinato. If the song calls for playing the same motif over and over, don’t think of it as boring. Think of it as hypnotic, tension-building, relentless, and an exercise in restraint. Countless James Brown songs bear this out, but my current favorite example is the bass line on the Pointer Sisters’ swampy cover of Allen Toussaint “Yes We Can Can,” which was played by Richard Greene of the Hoodoo Rhythm Devils, aka Dexter C. Plates. Think about it: If Larry Graham, one of the baddest bassists there has ever been, could stick to the same note throughout Sly & the Family Stone’s “Everyday People,” then you too can deliver a repetitive figure when it’s called for.
Be supportive. Though you may stretch out from time to time, your main job is to support the song and your fellow musicians. Consider how you can make your bandmates sound better using your phrasing, your dynamics, and note choices. For example, you could gradually raise the energy during guitar solos. Keep that supportive mindset when you’re offstage, too. Some guitarists have an attitude of competitiveness and even scrutiny when checking out other players, but bassists tend to offer mutual support and encouragement. Share those good vibes with enthusiasm.
And finally, give and take criticism with ease. This one’s for all musicians: Humility and a sense of helpfulness can go a long way. Ideally, everyone should be working toward the common goal of what’s good for the song. As the bass player, you might find yourself leading the way.Fuchs Audio introduces the ODH Hybrid amp, featuring a True High Voltage all-tube preamp and Ice Power module for high-powered tones in a compact size. With D-Style overdrive, Spin reverb, and versatile controls, the ODH offers exceptional tone shaping and flexibility at an affordable price point.
Fuchs Audio has introduced their latest amp the ODH © Hybrid. Assembled in USA.
Featuring an ODS-style all-tube preamp, operating at True High Voltage into a fan-cooled Ice power module, the ODH brings high-powered clean and overdrive tones to an extremely compact size and a truly affordable price point.
Like the Fuchs ODS amps, the ODH clean preamp features 3-position brite switch, amid-boost switch, an EQ switch, high, mid and low controls. The clean preamp drives theoverdrive section in D-Style fashion. The OD channel has an input gain and outputmaster with an overdrive tone control. This ensures perfect tuning of both the clean andoverdrive channels. A unique tube limiter circuit controls the Ice Power module input.Any signal clipping is (intentionally) non-linear so it responds just like a real tube amp.
The ODH includes a two-way footswitch for channels and gain boost. A 30-second mute timer ensures the tubes are warmed up before the power amp goes live. The ODH features our lush and warm Spin reverb. A subsonic filter eliminates out-of-band low frequencies which would normally waste amplifier power, which assures tons of clean headroom. The amp also features Accent and Depth controls, allowing contouring of the high and low response of the power amp section, to match speakers, cabinets andenvironments. The ODH features a front panel fully buffered series effects loop and aline out jack, allowing for home recording or feeding a slave amp. A three-position muteswitch mutes the amp, the line out or mute neither.
Built on the same solid steel chassis platform as the Fuchs FB series bass amps, the amps feature a steel chassis and aluminum front and rear panels, Alpha potentiometers, ceramic tube sockets, high-grade circuit boards and Neutrik jacks. The ICE power amp is 150 watts into 8 ohms and 300 watts into 4 ohms, and nearly 500 watts into 2.65 ohms (4 and8 ohms in parallel) and operates on universal AC voltage, so it’s fully globallycompatible. The chassis is fan-cooled to ensure hours of cool operation under any circumstances. The all-tube preamp uses dual-selected 12AX7 tubes and a 6AL5 limiter tube.
