Capable of the characteristic cleans and light overdrive that made its predecessors famous, the amp is also able to achieve high gain at less-than-ear-splitting volumes.
Ampeg Amplification’s guitar amplifiers of the ’70s were designed to stay clean at high volumes—a notion that set them apart in an era when it seemed everyone was trying to get overdriven tones at lower volumes. Despite Ampeg’s efforts, players quickly realized that pushing those clean Ampegs into overdriven territory yielded some very unique tones, and their sound quickly became a mainstay in the rock and pop music of that decade.
Fast-forward a few decades later, Ampeg has introduced the new GVT series a range of amps including the GVT15H reviewed here. It’s designed with a slightly different mindset than its ancestors—so while it’s capable of the characteristic cleans and light overdrive that made its predecessors famous, it’s also able to achieve high gain at less-than-ear-splitting volumes.
Honey, I Shrunk the V4
The GVT15H is a clear nod to Ampeg’s second golden age, even if it isn’t based on any specific model from the late ’60s or ’70s. Still, the tiny, 12 lb head looks like a shrunken V4 model with a similar control layout to match.
The amp’s all-tube circuit is driven with the help of a pair of 6V6 power tubes and a pair of 12AX7s in the preamp. There’s only one channel in the GVT15H, and simplicity and straight-forward tone is clearly the aim here. But there’s still a lot of tone-shaping potential, starting with controls for Gain, Treble, Midrange and Bass. Output is controlled by a simple master volume control and options for 15 watt or 7.5 watt output, which you can select with the standby switch.
Interestingly—and this is a high point if you’re a fan of vintage Ampeg amps—the three-band EQ section utilizes a Baxandall EQ configuration. If you’re like most players, you’ve probably rarely heard of this type of EQ, but when well executed the type is typically much more interactive than more common multi-band stack. Dropping the highs and lows can actually boost the midrange in a Baxandall EQ, and while it can take some getting used to, when used properly it makes the amp sound much more distinct. It was a hallmark in old Ampeg amp designs, and a big reason why so many players gravitate toward those classic pieces of gear.
Ampeg also managed to cram a small spring reverb tank into the chassis, along with a series effects loop. Both can be switched in and out (hard bypass) of the circuit via an optional two-button footswitch that can be ordered from Ampeg.
Blast from the Past
The GVT15H is a great-sounding amp that can cover a lot of musical ground, but it really excels at ’70s hard rock tone and ’60s clean jangle with a hint of edge and grittiness. It’s not capable of fire-breathing molten metal, but if your tastes gravitate towards muscular rhythm work and detailed cleans, it’s a powerful little amp.The head was tested through the amp’s matching closed-back cabinet—a GVT112E—which was loaded with a 12” Celestion Vintage 30 speaker. The combination of Celestion’s tried-and-true Vintage 30 with the Ampeg’s luscious voice was a great match—full of detail in the highs and lower midrange and infused with that classic vintage Ampeg clean tone that’s moderately bright with a trace of darkness that tames the high end.
With a 2011 Fender American Stratocaster out in front of the GVT15H, gingerly picked, arpeggiated chord progressions were warm and enveloping. As I delved into more country and rock oriented fills and progressions, the snappy, staccato picking style coaxed juicy grit in the mids while the amp displayed remarkable touch sensitivity.
A Gibson Les Paul Traditional coaxed both fluid gain and brawny midrange from the little Ampeg. Nudging the gain control makes the tone beefier and adds sting in the high end that becomes more vicious the higher I went. The added low end can make things surprisingly bottom heavy too, and I had to be careful to keep the Bass control around noon at higher volumes and gain settings to keep from washing out the rest of the tone spectrum.
The amp really kicks into high gear when you crank the master volume above two o’clock, pushing the power section into beautiful, velvety overdrive that works in tandem with the amp’s preamp gain. Thrash metal guitarists need not apply, but heavy rockers who appreciate high gain rhythm tones, ranging from classic ’70s raunch to early ’90s grunge, will be psyched. The only problem with achieving higher gain tones at maximum wattage is that the GVT15H can be surprisingly loud. The option to bump volume down to 7.5 watts is invaluable.
The Verdict
In terms of packing the classic, bright-with-trace-of-darkness Ampeg tones of yesteryear into a compact package, Ampeg did a great job. The cleans have a stark, but full-bodied nature to them, and the overdrive tones can be quite stunning—provided that the bass is adequately dialed back to let the rest of the frequencies shine through. If you’re a fan of the throwback ’70s tones that Ampeg helped define decades ago—but need to keep the volume level in check—it’s a pretty sweet deal.

Line 6’s DL4 Delay Modeler turns 25 and gets a supercharged update.
As long as humans have been creating art, they have also been inventing new tools for expressing that art. From the paintbrush to the synthesizer, new technologies have driven paradigm shifts, providing artists with fresh creative avenues. Technology drives the art, as they say.
That’s certainly been the case with Line 6’s DL4 Delay Modeler. Originally conceived as a humble digital delay, the Big Green Monster has created a niche of its own, serving as ground zero for entire new genres of indie and experimental music. Since its release 25 years ago, the DL4 has enhanced the creative palettes of artists ranging from Joe Perry, Mike Campbell, Dave Grohl, and Joe Satriani to Bill Frisell, Thom Yorke, and Ed O’Brien.
Nearly a quarter century later, Line 6 has introduced the DL4 MkII. The updated version features a smaller footprint, as well as increased delay time, sampling and recording via built-in micro-SD card reader, MIDI functionality, and a host of new effects algorithms from Line 6’s legendary HX family of amp and effects processors.
Inauspicious Beginnings
In the late 1990s, fresh from making a disruptive splash with their eye-catching POD amp modeler, the fledgling startup Line 6 set their sights on creating a series of pedals that would further extend their reach into digital emulations of effects. Plans called for the DM4 distortion modeler, the MM4 modulation modeler, the FM4 filter modeler, and the DL4 delay modeler.
The DL4 would include models of classic delays like the Echoplex and Roland Space Echo, as well as Line 6’s own innovative delay algorithms. But it was the DL4’s other features that would pique the interest of adventurous musicians, including a first-of-its-kind tap-tempo function and, of course, its now-legendary looper.
Jeorge Tripps was running his own boutique pedal company, Way Huge, when he was invited to consult with Line 6 on modeling vintage pedals. A few months into the project he was offered a position with the company. “Line 6 was like college for me,” Tripps recounts. “I had worked on things on my own, but developing a product with a team was really an education. Ideas are easy, but bringing a product to fruition as a team was a whole different experience.”
The team comprised the cream of the Line 6 brain trust, including co-founders Michel Doidic and Marcus Ryle, as well as product developers Greg Westall, Jeff Slingluff, and Patrick O’Connor, engineers Nigel Redmon and Kevin Duca, industrial designer Lucien Tu, and numerous other contributors. As Tripps observes, the input of those different perspectives was critical to the project.
“Most of us were also players, and that made a difference. You can create a product that’s great from an engineer’s perspective, but when you put it the hands of an artist, they might see something completely different in it.”
Keep It Simple
Simplicity was part of the design goal of the DL4. “The idea was to create a digital pedal with analog functionality,” explains Tripps, adding that he had limited input into the design. “Much of it was already planned out by the time I joined the project. The industrial design was there. I had to figure out how to map functions to the existing hardware.”
The interface was straightforward: a 16-position mode selector knob, five knobs to adjust parameters, and four analog-style footswitches: Record/Overdub, Play/Stop, Play Once, and 1/2 Speed/Reverse. It was Tripps who suggested the fourth button be used for tap-tempo function.
The DL4 also incorporated stereo outputs, which was something of a last-minute addition. “When the DL4 first came out, very few guitarists were playing stereo rigs,” Tripps reports. “We put it in there just because it was cheap and easy to implement. Only after it was out for a while did people start discovering it.”
Tripps also played a key role in promoting the looper, which was in some ways almost an afterthought. Of course, looping itself was nothing new. The Echoplex and other tape-based delays had been around for decades. But analog delays were expensive and unwieldy for live work, and the early digital pedals didn’t have a lot of memory—certainly not enough for looping.
In fact, it was digital’s limitations that contributed to another of the DL4’s characteristic sonic features. “Technically, we couldn’t get quite 15 seconds of loop time; it was like 14 and change,” Tripps recalls. “So we decided to take that remaining few hundred milliseconds of delay time and run that through the looper.”
A Slow Build
Despite Line 6’s aggressive advertising, the DL4 and its siblings were not an immediate hit. “People didn’t really know what it was at first,” says Tripps. “It didn’t really explode until a handful of people started doing stuff with it.” Slowly and steadily, artists as varied as Dimebag Darryl, Ed O’Brien, The Edge, and Thom Yorke started squeezing whole new sonic landscapes from the diminutive box.
Minus the Bear’s David Knudson made the DL4 an integral part of the band’s sound. “At first I was mesmerized by the rad stereo sounds. Playing in a hardcore/metal band at the time, in the beginning I was using one half-stack amp. At some point down the line, I realized that as the only guitar player I should get another half-stack for the other side of the stage. Once I plugged in the DL4 to each half-stack and found the Ping Pong delay, my mind was instantly blown. The melodic guitar parts had never sounded so huge and epic. It was the beginning of an epic journey to discover what all the delays were about.”
For Joff Oddie of indie rockers Wolf Alice, the experience was equally liberating. “I actually don’t think I’d even used a delay pedal before and it blew my mind. There were sounds that I expected, and then other settings like the Sweep delay and reverse sounds, which to me sounded so otherworldly yet at the same time organic. I never gave my manager the pedal back. I hope he doesn’t read this.”
As Knudson notes, it was many years later and a happy accident in the studio that led to his discovering the DL4’s looping function. “We were recording some demos after our first LP came out and I think out of boredom I played a little tapping lead into the looper. That song would become “Fine +2 Points,” which features a re-triggered loop section in the bridge that really opened the door for me. After that little successful experiment, for our next record, Menos El Oso, I was in full-on loop and sampler mode. I realized that with multiple DL4s I could emulate some of my favorite cut-up and glitchy sounds coming out of artists like Four Tet, DJ Shadow, Caribou, and other early EDM pioneers. The one-shot function allowed me to re-trigger samples and create riffs that sounded like they should have originated on an MPC. Eight of the 11 songs on that record have sampled riffs and re-defined what guitar playing meant for me.”
Of course, looping was only part of the DL4’s broader appeal, which also offered sounds and tactile control previously unavailable on most effects pedals. “I loved how cranking the feedback knob made it go crazy,” opines Oddie, “how the time knob sounded when you wiggled it and the delays pitch shifted. Part of its charm is how incredibly tactile it is.”
“I’ve yet to find another sampler pedal that works as well as the DL4,” adds Knudson. “It’s super easy to use and so straightforward that it’s perfect for the live setting. I don’t want a bank of digital menus to scroll through, and the fact that it can get everything I need done with four buttons is perfect. If it were any more complicated I don’t think it would have been nearly as successful as it has become.”
Like most legends, the DL4 has spawned a host of imitators. Looping and sampling have become powerful tools for guitarists and other musicians, and while the DL4 may not have been the first, it’s largely seen as the big daddy of the art form.
“The DL4 didn’t really break any new ground, yet it was a major leap,” observes Tripps. “It didn’t improve on existing delays as much as it created a whole new instrument. It put a lot of power on the floor for guitarists, along with a really intuitive interface. Almost by accident, it made looping accessible for live performance.”
It’s hard to believe it’s been nearly 25 years since the DL4 made its debut. Technology has obviously come a long way since then, and Line 6 has recently unveiled a new commemorative 25th Anniversary edition of the iconic pedal. The Mk II version adds to the legend without taking away the features that made it what it is. “The MkII just improves upon an already great pedal,” Knudson observes. “Honestly, one of the best things is just the smaller footprint on the pedalboard. As we know, boards are increasingly becoming competitive as to how much stuff you can squeeze on there! But I love the additional delays and reverbs. The classics are obviously my go-to choices, but I love how it has evolved and elevated with current trends with guitarists but still stayed true to form in what made it so wonderful in the first place.”
The quiet impact of the DL4 is something no one would have foreseen. Much like a band making a record, all the best laid plans won’t predict the public’s response. Will it thud like a tree in an empty forest, or be gone tomorrow like a flash in the pan? Like a hit single, only time will tell if it has the staying power to become a legend. As Tripps concludes, “It was the right combination of great minds, great ideas, and great execution, at the right time.”
