When Japanese engineer Susumu Tamura designed the Maxon OD808 overdrive, he could hardly have known that it and its export twin, the Ibanez TS808 Tube Screamer, would become perhaps the most influential and, probably, imitated pedals in stomp box history. In fact, upon its introduction in 1979, the Tube Screamer, whose smooth sound is characterized by a bass roll off, midrange bump, and slight high-end attenuation, was not an instant success. But as the pedal was adopted by players as disparate as Stevie Ray Vaughan and Kirk Hammett, it gradually became a ubiquitous presence on pedalboards of all persuasions.
Tumura, a guitarist himself, spent several of the intervening decades working on wireless designs. In recent years, however, he began modifying Tube Screamers for Japanese guitar stores. But now in his seventies, he found the pace—almost 1,000 pedals annually—exhausting. Why not, he thought, just make a pedal that incorporated all his refinements? Enter the TWA SC-01 Source Code, which is exactly that. Handmade in the U.S., the SC-01 features improvements on the TS design, including 18V operation via an internal regulator, a +6 dB boost, anop amp that claims toinject “complex harmonics and an amp-like feel,” and, most importantly, a “Bite” control that can mix in asymmetrical, tube-like clipping to the symmetrical clipping-based sound of the original.
Source in Session
Using a Stratocaster and Fender Princeton Reverb as my test platform—a made-for-Tube Screamer rig if there ever was one—I first determined whether the Source Code could speak traditional Tube Screamer by A/B-ing it with a recent Ibanez TS-9 reissue. It does, producing tones indistinguishable from the traditional circuit when the bite control is at zero. That said, if your take on Tube Screamers has always been, “if it could only just…,” you’ll find that the bite knob opens up a whole new world. Goosing it adds the extra measure of sizzle, zing, and teeth that more common iterations of the design always lacked. And adjusting the balance of the drive and bite controls dials in an enhanced and expanded range of overdrive tones that truly transcend the original TS.
The Verdict
Whether you deploy Susumu Tamura’s latest refinement of the TS circuit to hit the input of an amp that’s already breaking up or as your primary source of overdrive, you won’t be disappointed. It offers all the essence of the original, but it’s the extra oomph and range that impresses.
The tweedDeluxe circuit sets the gold standard in tone for many of us. And for good reason. It’s simple and responsive, with a warm, compressed, midrange-forward voice that’s perfect for jazz and country lines at low to moderate volumes—and a distinctive, saturated gnarliness in the upper reaches of its output that’s hard to beat for rock. If that’s the sound you hear in your head, many would say a vintage model is still the one to have.
If anyone could top that with a true “tweed killer,” I’d put my money on George Alessandro. That’s not just because his clientele reads like a Mount Rushmore of guitar tone—David Gilmour, Derek Trucks, and Warren Haynes are just a few who’ve cited Alessandro in current gear lists in PG. It’s the combination of his deep firsthand knowledge of the history of guitar amp circuits and his tireless quest to source the finest components that not only land him those rock-star devotees, but easily place his name among mythical amp wizards like Alexander Dumble and Ken Fisher, and make him the guy for the job.
I’ve had the good fortune to play one of Alessandro’s 5E3 copies, and it was so familiar, it felt like what I imagine one of those amps must have sounded like fresh out of the factory in the late ’50s. With his new combo, The Dane, he’s used that circuit as a jumping off point—with a nod toward Dumble as well—and optimized it for a modern pedal-using player. Not only does the 14-watt The Dane deliver the same sonic hallmarks as the 5E3, it offers more headroom and an even wider range of touch-sensitive response.
Do the Evolution
Despite all the tweed Deluxe talk, the Dane is no clone. Instead, it’s inspired by the 5E3 circuit and a Dumble Tweedle Dee—that legendary amp builder’s own tweed Deluxe mod—that landed on Alessandro’s bench for service. From there, Alessandro evolved the design, creating a unique preamp circuit, which uses a pair of ECC83MG/12AX7s. On the user end, the most recognizable change might be the inclusion of a 3-band EQ. Alessandro paired his preamp with a ’50s-style output section that employs a pair of 6V6s. Together, and in conjunction with Alessandro’s signature Eminence GA-SC59, they evoke a vintage vibe, achieving the tube compression and harmonic complexity tweed Deluxe players know well, but with more clean volume.
As a tweed Deluxe player who also loves pedals, I’ve often found myself a little bit conflicted. There’s a weird imaginary line I feel like I cross every time I plug a fuzz—or even worse, a digital pedal—into my 1949 5A3. But if I want to use my prized amp on as many gigs as I do, it’s a necessity. With The Dane, not only is there no conflict, it actually feels more welcoming to pedals. That’s not just about headroom, though that certainly helps—the 3-band EQ really goes the distance when it comes to shaping your sound.
Much like the dynamic interplay between the tone and volume controls on a vintage Deluxe, each of The Dane’s EQ controls seems to shape the whole of the sound. I found this to be especially helpful with dialing in dirt tones. Over the course of a few sessions with The Dane, I plugged in a wide range of gritty pedals, including a Klon KTR, Analog Man King of Tone, EHX Ripped Speaker (there’s some comedy here in using a fuzz that’s supposed to sound a little broken), and an Analog Man Sun Fuzz. In each, I found that I was able to shape their tones with the EQ more than I would ever expect from other amps. And that goes for using those to push The Dane into overdrive as well, which, as ruthlessly delightful as it is to do on a tweed Deluxe, is not especially sculpt-able. With the KTR adding some gain and heading into cranked volume territory, the mid control alone added a heft to my Creston JM-style that felt resolutely heavy and thick—much more so than I would expect from JM-style pickups. And at more polite volumes, I could use the pedal alone to get my overdrive, while still preserving the character and voice of the amp.
Full Control at Your Fingertips
While reviewing The Dane, there’s a quote that kept coming back to me from when I interviewed Alessandro a few years ago: “If I can make it a limitless journey, then I did my job right.” With The Dane, he’s managed to take the tweed Deluxe sound and remove the limits.
I think there are a lot of ways Alessandro gets there, and one of those is through his next-level component sourcing. With the fervor of a hi-fi aficionado, Alessandro has most of his components custom built, with quality control that goes well beyond the consumer-grade level.
The result is that The Dane, like every Alessandro amp I’ve played, responds like a performance sports car: It runs silently, has an ultra wide dynamic range, a broad frequency range, and is fast and articulate, all of which keeps control in the player’s hands. That might be daunting if you’re used to an amp that heavily colors your phrasing by limiting the window of control (though pedals can help with that). But if you want to keep that window wide open, The Dane will get you there.
What, exactly, does that mean? The response, dynamics, and EQ keep the controls in your hands. Playing intensity and attack have more noticeable results. Sustain is there when you need it. In short, The Dane is a thrill to play.
The Verdict
As a devoted tweed Deluxe user, I’m genuinely taken by The Dane. Alessandro has preserved the character of the original while opening it up with more dynamic range, control, and possibility. But it goes beyond that, because The Dane isn’t just a 5E3-style amp—it’s a solution. Whether you’re playing clean articulate lines (I didn’t have an archtop handy, but I can assure you this amp would be the perfect transparent companion for jazz hits) or cranking with abandon, The Dane has the harmonic range and firepower for the gig. Its 14 watts are not only bold and powerful, this combo maintains its composure through its entire output, making it fully usable at all levels. At $3,000, The Dane, handmade by one of the ultimate legends of amp building, is an unrivaled feat.
Running two effects of the same kind concurrently can yield amazing results. Stacked fuzzes or RATs? I’m in heaven. Other effects work less reliably well in pairs. Two reverbs, for instance, can sound killer but can turn an otherwise carefully crafted signal to smog. Twin phasers, in my experience, can be counted among the effects that are delicious together. It takes just two simple one-knob phasers to get very weird. Build two phasers into one, though, and add a few extra tone shaping controls, and the weird gets weirder fast.
Keeley’s new U.S.-made, digital Oaxa twin phaser can feel nearly as simple and straight ahead as two Small Stones running side by side, and honors the elegance and ease of that solution in many ways. There’s just three knobs—for rate, feedback, and depth. A small 3-position toggle switches between 10-stage phase, 4-stage phase, and a Uni-Vibe-style mode. Two footswitches select between the individual phaser or a combination of the two. If you want to keep things simple, you can dive in no further than that and have a great time. But Oaxa bears many secrets for deeper diggers.
Working the Waves
The phase effect is fun to use intuitively. And adding it in and out can be low stakes. Feeling that a riff sounds lifeless? Add a phaser and twist the rate. Maybe it’ll be exactly what a song needs. Maybe it will sit like rotten mayonnaise. But it won’t have taken much effort to try, and you’ll probably have fun along the way. The Oaxa is deeply satisfying in this manner.
The brilliant, big rate knob can be adjusted with precision using just a toe (provided you have the right shoes). And while the depth and feedback controls might be an affront to Phase 90 and Small Stone users, Oaxa’s controls open up useful phase possibilities without leaving you feeling doomed to get lost in the weeds. The depth control, for instance, has so much range it can render the phaser all but subliminal—making it a killer always-on sweetener that can be nudged in and out of prominence via the depth knob. Those just-barely-there depth settings can also be subtly re-shaped by the similarly rangey feedback control, which acts like a filter, adding wah-like focus at mild depth. At more intense depths, the feedback adds appreciably more vowelly “wow” tonalities that give Oaxa more than a hint of a Mu-Tron’s beautiful vintage essence. This variation—and interactivity—among depth and feedback colors alone makes Oaxa a great production, arrangement, and guitar layering tool, particularly in spacious arrangements.
Bear in mind that all the phase phenomena I’ve described here were observed in the 4-stage phaser voice—my most natural and familiar phase space. But the 3-way toggle can also be configured for 10-stage voicing or as a Uni-Vibe-style phase effect. The 10-stage voice is a little more binary than the 4-stage, and can obscure some overtone nuance in the wash. At extreme depth settings it can even sound almost tremolo-like. For a lot of players, the more focused modulation waves in the 10-stage voice will be a perfect fit for rhythmic delays or staccato passages begging for a little extra wobble and a more interesting tail. The Uni-Vibe style setting, meanwhile, is a pretty authentic version of the effect and delivers a recognizable take on the drippy “whoop”-like phase created by a Uni-Vibe’s optical circuit. Like the real deal, it sounds fantastic with fuzz.
Multiplied by Two ... and More
When both phasers are on, Oaxa’s jewel lamp flashes blue and red, and the visual suggestion of a party is apt. There are deep and crazy sounds here that can take you deep into the wee hours. But not all combinations are magic. Certain pairings of modulation rate and harmonic peaks can obscure details that might make a single phase voice pleasing. But the option to run the two phasers in parallel or series enables more or less detailed versions of a compound phaser voice, respectively. And just-right phase-rate relationships combined with contrasting voices, depth, and feedback can yield fantastic results. Fast-throbbing U-Vibe style modulations combined with slow, deep 4-stage phases are extra dimensional—as are just about any two high-contrast rates. Nailing these combinations and hearing them via stereo—the other great force multiplier on Oaxa—can pull you deeper still into the pedal’s capacities.
The Verdict
Do you remember what I said at the top about the Oaxa being simple? It’s true. It’s just that Oaxa’s elegant design also has a lot in store for troublemakers willing to dig a bit. And if the stereo and dual-phase settings aren’t trouble enough, you can use the footswitches and knobs to introduce compression or extra filtering, or reconfigure the toggle to include 2- and 6-stage phaser voices. I’d venture that using the most basic functions will make the $199 price well worth it over time. But you’ll likely celebrate the day you stumble across one of Oaxa’s more complex finds. I suspect such days will be many in number, too.
Any effect can color a guitar’s personality and language. But Boss’ new XS-1 Poly Shifter literally stretches the instrument’s vocal range. With the ability to shift input by +/-3 octaves or semitones, it can turn your guitar into a bass, a synth, or a baritone, or function as a capo. It also seamlessly generates harmonies for single note leads and keeps up with quick picking without any apparent latency. Furthermore, the pedal is capable of stranger fare that stokes many out-of-the-box ideas. But if you’re a guitarist that plays more than one role in your band—or musical life in general—the XS-1 can be a utilitarian multitool, too. It’s a pedal that can live many lives.

The XS-1, which was released alongside its bigger, more intricate sibling, the XS-100, is an accessible route to exploring pitch shifting’s potential. Housed in a standard Boss enclosure, it doesn’t consume a lot of floor space like the XS-100 or DigiTech’s Whammy. And while it achieves this spatial economy in part by forgoing a built-in expression pedal (which could be a deal breaker for some potential customers) it’s still capable of +/- seven semitones and a +/- three-octave range that can be utilized in momentary or latching applications.
Slipping, Sliding, and Twitching
Though digital pitch shifters have always been capable of amazing things, early ones sounded very inorganic at times. High-octave sounds in particular could come across as artificial, like the yip of a robot chihuahua plagued by metal fleas. Some very creative players use these colors—as well as the most sonorous pitch shift tones—to great effect (Nels Cline and Johnny Greenwood’s alien tonalities come to mind). In other settings, though, these older pitch devices can be downright cringey.
“The pedal clearly represents several leaps forward from first-generation pitch shifters.”
The XS-1 belies digitalness in some octave-up situations. But the pedal clearly represents several leaps forward from first-generation pitch shifters. Tracking is excellent and shines in string bending situations. Semitone shifts can provide focused harmony or provocative dissonance depending on the wet/dry mix and which semitones clash or sing against the dry signal. At many settings the XS-1 feels alive and organic, too, with legato lines taking on many of the touch characteristics of a violin-family instrument. You get far less of a note-to-note “hiccup,” and glissandos take on a beautifully fluid feel—with or without a slide—letting the XS-1 deliver convincing pedal- and lap-steel-style textures when you add a single octave up. (Such applications sound especially convincing when you kick back on guitar tone and restrict your fretwork to the 3rd through 5th strings, which keeps digital artifacts at bay.)
Mixmaster Required
The most crucial XS-1 control is the mix. For the most convincing bass, baritone, and 12-string tones, you’ll want a fully wet signal. But composite sounds can be awesome, too. You can use the control’s excellent sensitivity and range to highlight or fine tune the prominence of a consonant harmony. But it’s sensitive enough to make blends with dissonant harmonies sound a lot more intentional and integrated. And many of these eerie, wonky, off-balance textures are extra effective when introduced in quick bursts via the momentary switch. (That switch can also deliver great flashes of drama with more consonant harmonies—like dropping in a 3rd or 5th above a resolving chord in a verse.)
You can get creative in other ways using dissonant blends. Droney open tunings can yield fields of overtones that sound extra fascinating with delay, reverb, or 12-string guitar… or all of them! Dialing in blends that really work takes some trial and error, and you’ll definitely hit a few awkward moments if you’re navigating by instinct alone. But those same experiments often uncover real gems—especially in the pitch-down modes, which tend to produce more mysteriously atmospheric textures than their pitch-up counterparts.
The Verdict
Boss’ most straightforward pitch shifter covers a lot of ground. If you play in a duo, trio, or small band, it can expand that collective’s stylistic and harmonic range. It’s small, at least relative to treadle-equipped pitch shifters, so if you’re not a pitch shift power user, you don’t sacrifice a lot of room for an effect you might only employ occasionally, and you can still use the expression pedal jack to hook up a pedal for dynamic pitch control. The $199 price puts it in line with competitors of similar size and feature sets, but the XS-1 is a great value compared to more elaborate, treadle-equipped pitch shifters. If you’re taking your first forays into pitch shifting, or know that you need only the most straightforward functions here, it will ably return the investment. And along the way, it might even unlock a whole cache of unexpected tonal discoveries.
Connecticut builder Josh Forest’s TreeTone Guitars specializes in retro-inspired designs with hip offset bodies, classic inspired color combos, and an array of electronic options. He’s teamed up with Orangewood to offer an imported version of his Del Sol model—which he produces in a standard-tuning version under his own name—as a baritone. Although the Orangewood Del Sol Baritone hits a price point well below a domestic build, it’s a solidly crafted, handsome guitar that punches well above its $795 tag.
Comfy Feels
The Del Sol Baritone’s slick, unique offset mahogany body evokes retro Fender vibes, but on its own terms. It’s a sleek look, and thanks to its chambered design—with a bass-side f-hole—it’s lightweight.
Playing while seated, the bari has a nice weight distribution and offers a comfortable playing experience. Its 27 1/2" scale length is close enough to a standard scale to feel familiar, giving it a more guitar-like feel than, say, a Danelectro’s 29 3/4" scale or a Bass VI’s 30", which makes it easy to get acquainted with.
Without checking price data first, I guessed it was priced a few hundred bucks above its $795 cost direct from Orangewood.”
A pair of P-90s sit nicely in the 3-ply parchment pickguard. Controls include a master volume and tone with pickup selector, plus a phase switch. Characteristically, the P-90s tend toward warmth more than clarity, but together they have a wide range, from bridge-position twang to thick neck tones. They certainly lean dark, and digging in will push their output enough to drive the amp if you’re already heading in that direction. That’s particularly the case with the neck pickup, though tamping down the bass control on my Deluxe Reverb helped keep it cleaner longer. But the P-90s performed great once overdriven, whether from the amp or with the help of a dirt box, with plenty of sonic space for well-articulated arpeggios and dynamic strumming. I preferred the middle position most, and the phase switch—located on a brushed aluminum control plate between the volume and tone knobs—opens up the possibilities. It’s a helpful control, especially for navigating bass response and finding the line between heaviness and twang.
Jack of All Trades
The Del Sol’s roasted maple neck has a smooth satin finish and a soft C profile. Combined with the 12" radius on its rosewood fretboard, the neck feels great. A rounded heel offers easy access to the upper frets, and has a spoke wheel for truss rod adjustment, which I always find to be a thoughtful and welcome feature. The 43 mm nut width feels naturally spaced for the .013–.072 strings that come stock.
As far as build quality goes, my demo model arrived set up and ready to go. The frets are even and nicely dressed across the neck, and seem to have received a fine level of attention. In fact, from top to bottom, the Del Sol’s build is flawless. Without checking price data first, I guessed it was priced a few hundred bucks above its $795 cost direct from Orangewood.
Though its offset aesthetic gives a bit of a surfy vibe, the Del Sol Baritone is more of a rocker—though I suspect replacing the Tune-o-matic-style bridge with a JM-style vibrato could push it in the former direction. It’s definitely capable of heavier sounds and plays well with distortion. The resonance of the chambered body lends some sustain across its range, and that helps this bari sing. The easy playability of the neck and fretboard open it up to all styles, and knotty, technical passages are easy to execute. That makes the Del Sol a specifically versatile instrument. The other side of versatility, though, is that if you’re looking for specialized sounds—let’s say a Dano-with-lipstick-pickup kind of thing, or a tic tac bass sound—you might not find it. But as a do-it-all baritone under $1,000, the Del Sol is one to consider.
The Verdict
The Orangewood brand model delivers attention to detail in cool aesthetic packages at easy-to-reach prices. Yes, there are less expensive baritones than the Del Sol on the market. But many of those cater toward more specific, if not a bit quirky, tastes. Instead, the Del Sol Baritone can cover a breadth of stylistic ground both sonically and, thanks to its easy playability, from a technical perspective. With a build quality that’s more consistent with a higher price point, it delivers both musical and financial value. If you want a well-rounded bari, this may be all you’ll ever need.
