Line 6 DL4 MkII
line6.com
Many guitarists reach a crossroads where they have to decide to either totally embrace their influences or shun them and find a new path. That applies to gear as well as playing style. Back in the mid ’00s, the Line 6 DL4 started popping up on pedalboards and I ran away. Sure, its extensive array of delay options and cool looper function were tempting. But while forward-thinking artists like Bill Frisell, Mary Halvorson, Battles, Lightning Bolt, and Reggie Watts used this green beast to create the most compelling sounds, the DL4 became ubiquitous. For whatever reason, I—and plenty of players like me—avoided the pedal in an odd attempt to stay clear of a trend.
Fast forward to the present and the DL4 is a modern classic. Its ubiquity diminished as new fleets of modern digital pedals came along offering endless delay-based possibilities. And yet some players still hang onto their trusty green pedals, despite their clunky, anachronistic, pedalboard real estate-hogging enclosures. There must be something special there, right? Luckily for all of us—those who are new to the DL4 or those devotees who want some upgrades—Line 6 has delivered the thoroughly modern DL4 MkII, with all the sounds and functionality of the original and plenty more.
Modern Times
Most reissues of old classics come with some kind of caveat—maybe they lack the essential capacitors of the original, tape has been replaced with DSP, or it’s a PCB version of a hand-wired circuit. A fun thing about the DL4 MkII is it’s just an updated version of the original, so there’s no compromising.
The MkII is immediately recognizable as a DL4, but it’s a little slimmer and sleeker, and its matte finish seems to boast about its modernity. Of course, it still takes up a lot more space on a pedalboard than lots of delay units that perform similar functions. With only six knobs and four switches, plenty of other pedal designers would choose to squish things up into a smaller enclosure. There’s a lot going on around back—stereo ins/outs, a mic in and level control, expression pedal out, MIDI in/out, micro SD slot (for saving loops and extending loop time), USB in, and power—so maybe that’s why they need all that space. I prefer to think that the folks at Line 6 decided that players simply need more space to think. As soon as I got started, I noticed how luxurious it feels to step on the MkII’s switches and not risk hitting another one by mistake. And grabbing the inset knobs doesn’t require a lot of precision or dexterity, so on-the-fly changes are as smooth as can be.
In a world of complex pedals, the DL4 design seems simple. A single knob controls a menu of 30 delay sounds. 15 of these are new, and a “legacy” button switches the function of that knob so you can access the original 15 options. There is also, of course, a looper function. The time, repeats, and mix knobs function as advertised, while the tweak and tweez knobs change function depending upon the selected delay voice. With so many delay-voice options, there is a lot to internalize in those latter two knobs, and I found myself consulting the enclosed paper guide more than I’d like. I’m sure that over the course of continued use and a few gigs I’d memorize some settings for easier control. But the three preset switches offer good starting points that get you close to where you want to be. That should get you going with minimal tweaking/tweezing.
Instant Tones and More
As an inexperienced DL4 user, I was pleasantly surprised at how easy it was to find the sounds I associate with the pedal. I’m mostly talking about the looper function that is utilitarian by today’s standards. Start/stop and overdubbing is simple, and the half-speed/reverse switch gave me insight into some of the most classic Frisell looping tricks.
I couldn’t find a bad delay sound in the bunch. The glitch voice would fit nicely within a Daniel Lanois production and feels reminiscent of the underrated DL4 contemporary, the Boss Slicer (albeit with simpler controls). The tunable harmony voice is of the same milieu and I felt encouraged to attempt my best Terry Riley-on-guitar impression. The auto-vol voice is an approximation of a Slow Gear-style effect and delivers the same sort of kosmische-like bliss, but also found me attempting faux-pedal-steel things that are candy for my ears.
Those are some of the MkII’s more experimental voices. Elsewhere, more straight-ahead delay tones such as the digital/vintage digital, analog mod, and lo res delay deliver exactly what they promise. Each is a unique voice that is easy to access and sounds solid across its settings.
I’m a purist when it comes to pedal design. And I prefer a pedal’s functions to be visible and relatively easy to manipulate. When a pedal has a secret function, it can feel like a cute Easter-egg bonus feature rather than a practical one. The surprise here is that the MkII comes loaded with 15 secret reverb sounds, which is a lot of hidden functionality. While a big part of the charm of the pedal is its simple control set, an extra knob or two would make access to these reverb voices much easier. There are a lot of reverb sounds here to explore, and I was drawn to the ducking, particle verb, and searchlights settings, But, again, the hidden functionality meant I mostly used the delay functions I could see.
The Verdict
The DL4 MkII is a fine update of a classic pedal. All the classic sounds are easily discoverable, as are all the new ones. The design is simple and easy to use. The hidden reverb function is a nice bonus, but it sounds so good that I’d like to use it more easily on the fly. That said, it’s hard to fault this pedal for that one flaw. The MkII offers a load of functionality in one unit that will appeal to experimenters and those with simpler delay cravings. This green machine is a classic for a reason and the MkII is going to keep it that way.

The luthier’s stash.
There is more to a guitar than just the details.
A guitar is not simply a collection of wood, wire, and metal—it is an act of faith. Faith that a slab of lumber can be coaxed to sing, and that magnets and copper wire can capture something as expansive as human emotion. While it’s comforting to think that tone can be calculated like a tax return, the truth is far messier. A guitar is a living argument between its components—an uneasy alliance of materials and craftsmanship. When it works, it’s glorious.
The Uncooperative Nature of Wood
For me it all starts with the wood. Not just the species, but the piece. Despite what spec sheets and tonewood debates would have you believe, no two boards are the same. One piece of ash might have a bright, airy ring, while another from the same tree might sound like it spent a hard winter in a muddy ditch.
Builders know this, which is why you’ll occasionally catch one tapping on a rough blank, head cocked like a bird listening. They’re not crazy. They’re hunting for a lively, responsive quality that makes the wood feel awake in your hands. But wood is less than half the battle. So many guitarists make the mistake of buying the lumber instead of the luthier.
Pickups: Magnetic Hopes and Dreams
The engine of the guitar, pickups are the part that allegedly defines the electric guitar’s voice. Sure, swapping pickups will alter the tonality, to use a color metaphor, but they can only translate what’s already there, and there’s little percentage in trying to wake the dead. Yet, pickups do matter. A PAF-style might offer more harmonic complexity, or an overwound single-coil may bring some extra snarl, but here’s the thing: Two pickups made to the same specs can still sound different. The wire tension, the winding pattern, or even the temperature on the assembly line that day all add tiny variables that the spec sheet doesn’t mention. Don’t even get me started about the unrepeatability of “hand-scatter winding,” unless you’re a compulsive gambler.
“One piece of ash might have a bright, airy ring, while another from the same tree might sound like it spent a hard winter in a muddy ditch.”
Wires, Caps, and Wishful Thinking
Inside the control cavity, the pots and capacitors await, quietly shaping your tone whether you notice them or not. A potentiometer swap can make your volume taper feel like an on/off switch or smooth as an aged Tennessee whiskey. A capacitor change can make or break the tone control’s usefulness. It’s subtle, but noticeable. The kind of detail that sends people down the rabbit hole of swapping $3 capacitors for $50 “vintage-spec” caps, just to see if they can “feel” the mojo of the 1950s.
Hardware: The Unsung Saboteur
Bridges, nuts, tuners, and tailpieces are occasionally credited for their sonic contributions, but they’re quietly running the show. A steel block reflects and resonates differently than a die-cast zinc or aluminum bridge. Sloppy threads on bridge studs can weigh in, just as plate-style bridges can couple firmly to the body. Tuning machines can influence not just tuning stability, but their weight can alter the way the headstock itself vibrates.
It’s All Connected
Then there’s the neck joint—the place where sustain goes to die. A tight neck pocket allows the energy to transfer efficiently. A sloppy fit? Some credit it for creating the infamous cluck and twang of Fender guitars, so pick your poison. One of the most important specs is scale length. A longer scale not only creates more string tension, it also requires the frets to be further apart. This changes the feel and the sound. A shorter scale seems to diminish bright overtones, accentuating the lows and mids. Scale length has a definite effect on where the neck joins the body and the position of the bridge, where compromises must be made in a guitar’s overall design. There are so many choices, and just as many opportunities to miss the mark. It’s like driving without a map unless you’ve been there before.
Alchemy, Not Arithmetic
At the end of the day, a guitar’s greatness doesn’t come from its spec sheet. It’s not about the wood species or the coil-wire gauge. It’s about how it all conspires to either soar or sink. Two guitars, built to identical specs, can feel like long-lost soulmates or total strangers. All of these factors are why mix-and-match mods are a long game that can eventually pay off. But that’s the mystery of it. You can’t build magic from a parts list. You can’t buy mojo by the pound. A guitar is more than the sum of its parts—it’s a sometimes unpredictable collaboration of materials, choices, and human touch. And sometimes, whether in the hands of an experienced builder or a dedicated tinkerer, it just works.

MT 15 and Archon 50 Classic amplifiers offer fresh tones in release alongside a doubled-in-size Archon cabinet
PRS Guitars today released the updated MT 15 and the new Archon Classic amplifiers, along with a larger Archon speaker cabinet. The 15-watt, two-channel Mark Tremonti signature amp MT 15 now features a lead channel overdrive control. An addition to the Archon series, not a replacement, the 50-watt Classic offers a fresh voice by producing retro rock “classic” tones reminiscent of sound permeating the radio four and five decades ago. Now twice the size of the first Archon cabinet, the Archon 4x12 boasts four Celestion V-Type speakers.
MT 15 Amplifier Head
Balancing aggression and articulation, this 15-watt amp supplies both heavy rhythms and clear lead tones. The MT 15 revision builds off the design of the MT 100, bringing the voice of the 100’s overdrive channel into its smaller-format sibling. Updating the model, the lead channel also features a push/pull overdrive control that removes two gain stages to produce vintage, crunchier “mid gain” tones. The clean channel still features a push/pull boost control that adds a touch of overdrive crunch. A half-power switch takes the MT to 7 watts.
“Seven years ago, we released my signature MT 15 amplifier, a compact powerhouse that quickly became a go-to for players seeking both pristine cleans and crushing high-gain tones. In 2023, we took things even further with the MT 100, delivering a full-scale amplifier that carried my signature sound to the next level. That inspired us to find a way to fit the 100's third channel into the 15's lunchbox size,” said Mark Tremonti.
“Today, I’m beyond excited to introduce the next evolution of the MT15, now featuring a push/pull overdrive control on the Lead channel and a half-power switch, giving players even more tonal flexibility to shape their sound with a compact amp. Can’t wait for you all to plug in and experience it!”
Archon Classic Amplifier Head
With a refined gain structure from the original Archon, the Archon Classic’s lead channel offers a wider range of tones colored with gain, especially in the midrange. The clean channel goes from pristine all the way to the edge of breakup. This additional Archon version was developed to be a go-to tool for playing classic rock or pushing the envelope into modern territory. The Archon Classic still features the original’s bright switch, presence and depth controls. PRS continues to stock the Archon in retailers worldwide.
“The Archon Classic is not a re-issue of the original Archon, but a newly voiced circuit with the lead channel excelling in '70s and '80s rock tones and a hotter clean channel able to go into breakup. This is the answer for those wanting an Archon with a hotrod vintage lead channel gain structure without changing preamp tube types, and a juiced- up clean channel without having to use a boost pedal, all wrapped up in a retro-inspired cabinet design,” said PRS Amp Designer Doug Sewell.
Archon 4x12 Cabinet
As in the Archon 1x12 and 2x12, the mega-sized PRS Archon 4x12 speaker cabinet features Celestion V-Type speakers and a closed-back design, delivering power, punch, and tight low end. Also like its smaller brethren, the 4x12 is wrapped in durable black vinyl and adorned with a British-style black knitted-weave grill cloth. The Archon 4x12 is only the second four-speaker cabinet in the PRS lineup, next to the HDRX 4x12.
