In a career defined by evolution, Joe Bonamassa is ready to turn the page once again. The blues-rock virtuoso has just announced Breakthrough, his most adventurous and genre-blending studio album to date, out July 18th via his own J&R Adventures.
At the heart of the announcement is the release of the album’s powerful title track—“Breakthrough' —a soulful, hard-hitting anthem about letting go, moving forward, and finding your fire again, available today on all streaming platforms.
Crafted across multiple continents and infused with a world’s worth of inspiration, Breakthrough marks a bold new chapter for Bonamassa—one that leans on fiery solos, emotionally rich storytelling, groove-driven arrangements, and stylistic exploration. Produced by longtime creative partner Kevin Shirley (Iron Maiden, The Black Crowes, Journey), the album was shaped by sessions in Greece, Egypt, Nashville, and Los Angeles, resulting in a vibrant sonic tapestry that shifts effortlessly from funky blues and Texas swing to acoustic ballads and swaggering hard rock.
Joe Bonamassa “Breakthrough” - Official Lyric Video
Watch the official lyric video for "Breakthrough" by Joe Bonamassa
“I think this album, Breakthrough, marks a shift in the styling of Joe Bonamassa’s recording output,” says Shirley. “While there are plenty of guitar solos on this record, his emphasis has been on songs primarily. Each time Joe undertakes a new recording project, he seems to access a different part of his vast library of music genre from the jukebox-in-his-head! This album is a round-the-world musical trip—from Little Feat funkiness to Texas swing, from hard rock power to acoustic singer/songwriter-style songs.”
The newly released single “Breakthrough,” co-written with longtime collaborator Tom Hambridge (Buddy Guy, ZZ Top, Lynyrd Skynyrd), captures the emotional core of the record—an uplifting anthem about transformation, persistence, and letting go of the weight that holds us back. With gritty vocals, melodic guitar lines, and lush instrumentation, the track embodies Bonamassa’s signature blend of power and finesse while ushering in a bold new direction.
“Breakthrough” follows the success of Bonamassa’s recent singles “Still Walking With Me” and “Shake This Ground,” both of which hinted at the adventurous spirit behind the full album. “Shake This Ground” delivered a moody, introspective edge, while “Still Walking With Me” leaned into warmth, gratitude, and classic soul. Each track reflects a different facet of Bonamassa’s evolving songwriting approach, rooted in emotional honesty and anchored by his unmistakable guitar work.
The album announcement caps a stretch of extraordinary momentum for Bonamassa. Next up, Bonamassa recently began his extensive *European Spring Tour, followed by a June run with his powerhouse supergroup Black Country Communion* (featuring Glenn Hughes, Jason Bonham, and Derek Sherinian). After another round of summer dates across Europe—including sold-out shows in Ireland—he’ll return stateside for his just-announced* 2025 U.S. Summer Tour*, a limited amphitheater run featuring stops at The Greek Theatre, Red Rocks, and more iconic venues.
With over 50 albums, 28 #1 Billboard Blues albums, and a lifelong commitment to evolving the genre, Bonamassa shows no signs of slowing down. Whether headlining iconic venues, mentoring rising artists through Journeyman Records, or supporting music education via his Keeping the Blues Alive Foundation, Bonamassa continues to shape the future of blues-rock with every note.

Great Eastern FX Co. Focus Fuzz Deluxe
Adding octave, drive, and boost functions to an extraordinary fuzz yields a sum greater than its already extraordinary parts.
One should never feel petty for being a musical-instrument aesthete. You can make great music with ugly stuff, but you’re more likely to get in the mood for creation when your tools look cool. Great Eastern FX’s Focus Fuzz Deluxe, an evolution of their très élégantFocus Fuzz, is the sort of kit you might conspicuously keep around a studio space just because it looks classy and at home among design treasures likeRoland Space Echoes, Teletronix LA-2As, andblonde Fender piggyback amps. But beneath the FFD’s warmly glowing Hammerite enclosure dwells a multifaceted fuzz and drive that is, at turns, beastly, composed, and unique. Pretty, it turns out, is merely a bonus.
Forks in the Road
Though the Cambridge, U.K.-built FFD outwardly projects luxuriousness, it derives its “deluxe” status from the addition of boost, overdrive, and octave functions that extend an already complex sound palette. Unfortunately, a significant part of that fuzzy heart is a Soviet-era germanium transistor that is tricky to source and limited the original Focus Fuzz production to just 250 units. For now, the Focus Fuzz Deluxe will remain a rare bird. Great Eastern founder David Greaves estimates that he has enough for 400 FFDs this time out. Hopefully, the same dogged approach to transistor sourcing that yielded this batch will lead to a second release of this gem, and on his behalf we issue this plea: “Transistor hoarders, yield your troves to David Greaves!”
The good news is that the rare components did not go to waste on compromised craft. The FFD’s circuit is executed with precision on through-hole board, with the sizable Soviet transistor in question hovering conspicuously above the works like a cross between a derby hat and B-movie flying saucer. If the guts of the FFD fail to allay doubts that you’re getting what you paid for, the lovingly designed enclosure and robust pots and switches—not to mention the pedal’s considerable heft—should take care of whatever reticence remains.
Hydra in Flight
Just as in the original Focus Fuzz, the fuzz section in the Deluxe deftly walks an ideal path between a germanium Fuzz Face’s weight and presence, a Tone Bender’s lacerating ferocity, and the focus of a Dallas Rangemaster. You don’t have to strain to hear that distillate of elements. But even if you can’t easily imagine that combination, what you will hear is a fuzz that brims with attitude without drowning in saturation. There’s lots of dynamic headroom, you’ll feel the touch responsiveness, and you’ll sense the extra air that makes way for individual string detail and chord overtones. It shines with many different types of guitars and amps, too. I was very surprised at the way it rounded off the sharp edges made by a Telecaster bridge pickup and AC15-style combo while adding mass and spunk. The same amp with a Gibson SG coaxed out the Tony Iommi-meets-Rangemaster side of the fuzz. In any combination, the fuzz control itself, which boosts gain while reducing bias voltage (both in very tasteful measure) enhances the vocabulary of the guitar/amp pairing. That range of color is made greater still by the fuzz’s sensitivity to guitar volume and tone attenuation and touch dynamics. Lively clean tones exist in many shades depending on your guitar volume, as do rich low-gain overdrive sounds.
The drive section is similarly dynamic, and also quite unique thanks to the always versatile focus control, which adds slight amounts of gain as well as high-mid presence. At advanced focus levels, the drive takes on a fuzzy edge with hints of Fender tweed breakup and more Black Sabbath/Rangemaster snarl. It’s delicious stuff with Fender single-coils and PAFs, and, just as with the fuzz, it’s easily rendered thick and clean with a reduction in guitar volume or picking intensity. The boost, meanwhile, often feels just as lively and responsive—just less filthy—lending sparkle and mass to otherwise thin and timid combo amp sounds.
Among this wealth of treats, the octave function is a star. It works with the fuzz, drive, or boost. But unlike a lot of octave-up effects, you needn’t approach it with caution. Though it adds plenty of the buzzing, fractured, and ringing overtones that make octave effects so wild and distinct, it doesn’t strip mine low end from the signal. The extra balance makes it feel more musical under the fingers and even makes many chords sound full and detailed—a trick few octave effects can manage. With the fuzz, the results are concise, burly, and articulate single notes that lend themselves to lyrical, melodic leads and power chords. In drive-plus-octave mode, there are many hues of exploding practice-amp trash to explore. The boost and the octave may be my favorite little gem among the FFD’s many jewels, though. Adding the octave to boosted signals with a generous heap of focus input yields funky, eccentric electric-sitar tones that pack a punch and are charged with character in their fleeting, flowering state.
The Verdict
It’s hard to imagine adding extra footswitches to the Focus Fuzz Deluxe without sacrificing its basic elegance and proportions, and without elevating its already considerable price. Certainly, there would be real utility in the ability to mix and match all three excellent gain modes. On the other hand, the output level differences between fuzz, drive, and boost are pretty uniform, meaning quick switches on the fly will shift texture and attitude dramatically without delivering an ear-frying 30 dB boost. And though it’s hard not be tantalized by sounds that might have been, from combining the fuzz and/or boost and drive circuits, the myriad tones that can be sourced by blending any one of them with the superbly executed octave effect and the varied, rangeful focus and output controls will keep any curious tone spelunker busy for ages. For most of them, I would venture, real treasure awaits.
Why is Tommy’s take on “Day Tripper” so hard? And what song would Adam Miller never play with him? Plus, we get Adam’s list of favorite Tommy Emmanuel records.
We call guitarist Adam Miller in the middle of the night in Newcastle, Australia, to find out what it’s like to play with Certified Guitar Player, Tommy Emmanuel. Miller tells us just how famous Tommy is in Australia, and what it was like hearing him play from a formative age. Eventually, Adam got to open for Emmanuel, and they’ve since shared the stage, so we get the firsthand scoop: Why is Tommy’s take on “Day Tripper” so hard? And what song would Miller never play with him? Plus, we get Adam’s list of favorite Tommy Emmanuel records.
Adam’s newly released trio album, Timing, is out now.
Plus, we’re talking about new recordings from Billy Strings and Bryan Sutton, as well as Brooklyn Mediterranean surf party band Habbina Habbina.
Patterns can be viewed as boring or trite, but a little bit of creativity can turn them into bits of inspiration.
Chops: Intermediate Theory: Intermediater Lesson Overview: • Learn different ways to arrange scales. • Combine various sequences to create more intersting lines. • Solidify your technique by practicing unusual groupings of notes. Click here to download a printable PDF of this lesson's notation. |
I want to offer some food for thought on making sequences musical. Using sequences in our playing helps develop our musicianship in various ways. It can help us tune into the fretboard, develop melodic ideas all around the neck, and further our improvisation and compositional skills. So, spending time with sequences is certainly not time wasted. Please note that I sometimes use the word “rule" in this column, this is only a pointer to keeping on track of our exploration of these concepts. The intellect is very useful, but intuition is where the creativity comes from. When in balance lots of great things can be done. Let's get stuck in!
It's simple to play a scale from bottom to top, or top to bottom, but we can develop a sequence by shuffling these notes around. In Ex. 1 we have a C Major scale (C–D–E–F–G–A–B) played in thirds followed by a sequence highlighting the diatonic triads of the major scale. By following a “rule" we can develop many different sequences. The options are endless and a little overwhelming.
Click here for Ex. 1
Lets start by simply combining an interval sequence with an arpeggio sequence. In Ex. 2, the first two beats of the first measure feature ascending thirds. This is then followed by a triad arpeggio starting from the third note on the string. The next set of thirds then starts on the “and" of beat 4. The entire sequence is a seven-note pattern that is created by combining two thirds and a triad. It gives us a nice bit of rhythmic displacement as the phrase is now starting in a different place in the measure.

Ex. 3 is a descending idea in A minor that basically flips the sequence we looked at in Ex. 2. Here, we are starting with two descending thirds before the triad. I'm using pull-offs and economy picking to articulate the triads. This one works well over D minor as well if you want a D Dorian (D–E–F–G–A–B–C) flavor.

You can see the effectiveness of combining different sequences and groupings of notes to create interesting runs. It's also really effective for making phrases. In Ex. 4 we take a small fragment from Ex. 3 and change the rhythm. In the sound example I repeat this a few times over some implied chords in my bass line: Am, F, and Dm. It's great to get more from one line by seeing the different chord types you can play it over.

In Ex. 5 we're going to start using fourths and fifths. It starts with an ascending A minor triad (A–C–E) before leaping to the 9 (B) and then hitting a G major triad (G–B–D). A similar pattern leads into the C major triad (C–E–G). Throwing in these wider intervals alongside triads is very effective for creating a dramatic sounding runs.

For our next example (Ex. 6), we will take fragments from Ex. 5 and space them out a bit. I wanted once again to show how these sequence ideas can also be helpful for developing melodic phrases. Once we have a cool sequence or fragment, all we need to do is be creative with how we play it. We can change the rhythm, harmonic context, dynamic, and much more.
Click here for Ex. 6
Before we move on, it's important to remember that we can add colorful notes to our triads. Let's begin with some seventh-chord arpeggios. Ex 7 features are diatonic seventh arpeggios in G minor (functioning as a IIm chord) to get a Dorian sound.
Click here for Ex. 7
Ex. 8 is a little gratuitous of me. It begins with an idea made of several different concepts. First, we start with an Am7 arpeggio (A–C–E–G), then descend down an A5 arpeggio. I follow that up with diatonic thirds and end with a pedal-point sequence. If that's not enough, we then take this bigger idea and fit it around a chord progression. I move it to G7, Dm7 and then I break my “rule" slightly and outline notes of a C6 arpeggio (C–E–G–A). However, it does keep the same melodic contour of the initial idea. I used my ear and fretboard to guide me. It's always healthy to have a fine balance between intellect and intuition.

We dig into C harmonic minor (C–D–Eb–G–Ab–B-C) for Ex. 9's monster two-measure lick. It sounds evil! In composing this phrase, I kept to the basic concept of finding seventh-chord arpeggios within C harmonic minor in the 8th position. I followed my ear as well as my slowly developing intellect. However, if you look closely you can see I was following a mini chord progression through this line. We start out with a CmMaj9 arpeggio (C–Eb–G–B–D) in the first beat, followed by a G7b9 arpeggio (G–B–D–F–Ab). Here we have a very strong Im-V7 movement in C minor. I then move back to our CmMaj9 arpeggio and in the second measure we start descending down an Eb augmented triad (Eb–G–B). This is then followed by more CmMaj9 goodness.
Click here for Ex. 9
Ex. 10 is now taking Ex. 9 and extending it into a cool flamenco-inspired melody. The rhythms in this were inspired by the incredible Paco De Lucia. I follow the sequence from the previous example almost exactly, but I use a bit of artistic license to repeat certain fragments to fit into a “top line" or “head"-style melody.
Click here for Ex. 10
My aim here isn't to give you one rule to follow but instead to encourage you to take the sequences you know and love and start getting more out of them. Enjoy and stay safe!
