Dynamic duo: Andy Timmons and Robert Keeley collaborated on the versatile, spanking new Super AT MOD, from Keeley Electronics.
Ever wonder how a manufacturer and an artist collaborate on a signature model? Here’s the story of the Keeley Super AT MOD Overdrive.
In the world of guitar gear, artist signature products are a time-honored tradition. When the chemistry works just right, they’re as potent and attention-grabbing as a well-struck power chord.
But if you’ve ever wondered how an artist and manufacturer actually work together on a product, the new Keeley Electronics Super AT MOD overdrive provides a striking case study in the mind-meld process.
While the new Super AT MOD looks like a classic 3-knob overdrive, the mode toggle is the pedal’s secret sauce, and the AT setting adds a particularly shimmering quality to the harmonically rich overdrive.
The versatile pedal is the latest creative partnership between ace guitarist Andy Timmons (known for his solo work and touring/recording with Danger Danger, Olivia Newton-John, Kip Winger, and many more) and Robert Keeley, a pioneer and leading presence in the realm of guitar effects.
In a collaboration spanning more than three years, Timmons and Keeley have become great friends, mutual provocateurs, and culinary kindred spirits. (More on that later.) They began working together in early 2020, when Timmons and Keeley teamed up on the wildly successful HALO dual echo pedal.“We spent more than a year-and-a-half really fine-tuning that pedal,” says Timmons. “It was a wonderful collaboration. We couldn’t have imagined how it would resonate with so many people.” Keeley adds with a laugh “I have found that my customers like what Andy’s ears like. It resonates so much with our customers that the Halo has become 25 percent of our business. Andy’s ears are really golden.”
Buoyed by the HALO collaboration, in late 2022 the creative process resumed in a new direction: a signature overdrive. In conceiving the new Super AT MOD overdrive, Timmons knew exactly what he was looking for: a flexible, highly responsive overdrive that can beef up a guitar’s tone but also offers an option to achieve high-end clarity and shimmer.
The initial inspiration for the Super AT MOD came from Timmons’ love of a classic Keeley mod for the Boss BD-2. “The modded BD-2 goes from clean to mid-gain, and it’s very responsive to touch,” Timmons notes. “But I was always reaching for this crystalline, glassy gain with just a little bite. So, with the new pedal we have two modes: a ‘phat mode’ which alludes to Robert’s original modded circuit, and then there’s the AT ‘modded modded’ side.”
Keeley Electronics Super AT Mod Overdrive - Video Demo Review with Robert Keeley and Andy Timmons
Andy Timmons and Robert Keeley talk about their collaboration for the new Super AT MOD, and Timmons displays its versatility and powerful dual-mode gain. You’ll also hear the guitarist use his other Keeley signature pedal—the HALO Dual Echo.
Sometimes Less Is More
Keeley took a different angle in designing the Super AT MOD. In contrast to his normal modus operandiof boosting certain frequencies, this pedal’s “modded modded” AT Mode is based on a subtractive method for sculpting the pedal’s tone.
“The original phat mod was designed to push up the bridge pickup of a Strat or Tele and give it a bit more girth,” Keeley explains. “But Andy pointed out that if we carve away some of the frequencies, his guitar will stand out more. Andy was approaching this from the opposite direction, playing with a pickup that’s much more akin to a humbucker, with a bigger dynamic range, so it doesn’t need that push on the low- and mid-bass.”
During the development and testing phase, Timmons relied primarily on his main guitar–his Ibanez ATZ100 signature model with three humbucking pickups–and his beloved Mesa/Boogie Lonestar 2x12 combo. But the final version of the pedal offers an expansive versatility that makes it a fine companion for just about any rig.
“I’m lucky to find these cohorts in tone. We enjoy the process and hopefully that comes through in the final product.”
That flexibility is due, in large part, to the aforementioned tone-shaping method that Timmons encouraged Keeley to employ. “To me, the subtractive approach is a great way to arrive at a better tone,” Keeley says. “You can take away some of the excess and it leaves you with something more natural. With that in mind, the AT mode changes the tone control and what it allows to pass through. It takes out some of the bass tones, so it clears up that range and makes humbuckers less bloated. We also added a little bit of sparkle—some high frequency response from letting the natural stuff go through.
“We also tried to get a more tube-like sound, with the diodes and asymmetrical clipping,” Keeley adds. “The Super AT MOD gives Andy that nice chimey top end and that tube-amp-type growl and distortion because it uses JFET transistors. They’re the closest thing we have to tubes.”Creativity and Camaraderie
The Timmons/Keeley partnership is a testament to technology—and to a friendship that blossomed during the long, sometimes grueling playing/listening sessions that punctuated the development process.
Timmons is based in McKinney, Texas, about a three-hour drive from Keeley headquarters in Oklahoma City, Oklahoma. That proximity allowed for frequent visits to the Keeley shop and made it easier for Timmons and the Keeley team to work together on the successive HALO and AT MOD prototypes. “You’ve really got to be able to be in a room together and feel what’s happening,” Timmons says. “Because we were all in the same room, we were able to go beyond what we had ever envisioned. That’s the blessing of them being just a few hours away.”
“The initial inspiration for the Super AT MOD came from Timmons’ love of a classic Keeley mod for the Boss BD-2.”
A key member of the creative team was Aaron Pierce, artist relations guru at Keeley Electronics. Pierce was deeply involved in the Timmons/Keeley collaboration right from the beginning, and he helped jump-start the process of designing the Super AT MOD.
“During the two years that we were working on the HALO,” says Pierce, “we were always talking with Andy about what he was looking for in an overdrive. So, we were working on ideas for at least a few months before getting Andy back into the process. We had learned a lot about his preferences during the HALO development.”
Timmons greatly appreciates what Pierce brought to the undertaking. “I can’t stress enough: Aaron was really the third side in the triangle. It was so important to have his ears in the room. Even if I couldn’t articulate to Robert what I was hearing, Aaron was able to do it, because he could hear it and put it into words in a way that Robert could act on. Aaron was the perfect translator between Robert’s methodology and what I was going for.”
The HALO design journey took two full years, but thankfully the AT MOD’s development was relatively brisk—perhaps three or four months, and three visits from Timmons. On each visit, Keeley would offer hospitality by cooking for the crew. Keeley is well known among his friends as a fantastic cook.
“It took more than three sessions—probably about six meals together,” Keeley says as all three burst into laughter. “The food really does stand out,” adds Timmons. “We didn’t lose any weight during the sessions.”
Ultimately, the Super AT MOD benefited greatly from the spirit of friendship and shared passion. “I was able to be really demanding because they were willing to go down the path with me,” says a grateful Timmons. “Their willingness to be open and do things differently was the key. I’m lucky to find these cohorts in tone. We enjoy the process and hopefully that comes through in the final product.”Lasting Impact for All

Asked if the collaboration with Timmons has opened a new approach for future designs, Keeley answers emphatically: “Most certainly. I’m going to use the subtractive process and implement that design philosophy on future pedals. That’s one of the reasons it’s so rewarding working with Andy: developing more and more chops to get nuanced sounds.”
Pierce agrees: “Working with Andy makes us better on the engineering front and the manufacturing front. Every time we collaborate with him it pushes us on our technology, and we discover things that we never would’ve found without him.”
At the end of the process—and a bunch of great meals with the Keeley team—Timmons is thrilled with the results: the Super AT MOD overdrive delivers the tone and versatility he sought. “I haven’t had a pedal feel like this before. It has such a natural thing about it. The dynamic range just coming from the fingers is incredible. It’s the delicate, mild gain that I’ve been seeking for a long time. But if I want to crank it up, it has incredibly powerful full-on gain.”
You can hear Timmons putting the pedal to great use on his brand-new series of singles under the title Bitter Suites: The Outlier Nocturne. Beginning with the first one, “Here Lies The Heart,” the ongoing solo series features Timmons’ playing in a spacious, dynamic setting, inspired by the Super AT MOD’s tonal range. “That AT mode is what I needed. Since that pedal was created, I’ve gotten the next two tracks because this was the sound I was waiting for.” Timmons attests.

Last year, Taylor Guitars capped its 50th Anniversary by introducing a new guitar collection celebrating the contributions of co-founders Bob Taylor and Kurt Listug to the guitar world. The Legacy Collection revives five of Bob Taylor’s classic acoustic models, curated by the legendary luthier and innovator himself. “To imagine that we’re doing guitars that harken to our past, our present and our future all at the same time,” Bob says, “I really like that.”
In developing the collection, Bob preserved the essence of his originals while integrating performance and playability upgrades introduced during his tenure as designer-in-chief. “It’s an up-to-date version of what those guitars would be,” Bob explains, “but with the same sound.”
Visually, these guitars feel classic—clean, understated and unmistakably Taylor. While Bob’s original aesthetic preferences are showcased in his Legacy models, the nod to the past runs deeper than trade dress.
From his earliest builds, Bob favored slim-profile necks because he found them easier to play. That preference set a design precedent that established Taylor’s reputation for smooth-playing, comfortable necks. Legacy models feature slim mahogany necks built with Taylor's patented New Technology (NT) design. “My first neck was a bolted-on neck but not an NT neck,” Bob says. “These are NT necks because it’s a better neck.” Introduced in 1999, the NT neck allowed for unprecedented micro-adjustability while offering a consistent, hand-friendly Taylor playing experience.
What makes this collection unique within the Taylor line is Bob’s use of his X-bracing architecture, favoring his time-tested internal voicing framework over more recent Taylor bracing innovations to evoke a distinctive tone profile. Since Andy Powers—Taylor’s current Chief Guitar Designer, President and CEO—debuted his patented V-Class bracing in 2018, V-Class has become a staple in Taylor’s premium-performance guitars. Still, Bob’s X-bracing pattern produces a richly textured sound with pleasing volume, balance and clarity that long defined the Taylor voice. All Legacy models feature LR Baggs VTC Element electronics, which Bob says “harkens back to those days.”
The team at Taylor thought the best way to demonstrate the sound of the Legacy guitars was to ask Andy Powers, Bob’s successor, to play them. A world-class luthier and musician, Andy has spent the past 14 years leading Taylor’s guitar innovation. In addition to V-Class bracing, his contributions include the Grand Pacific body style, the ultra-refined Builder’s Edition Collection, and most recently, the stunning Gold Label Collection.
Below you’ll find a series of videos that feature Powers playing each Legacy model along with information about the guitars.
Legacy 800 Series Models
First launched in 1975, the 800 Series was Taylor’s first official guitar series. Today, it remains home to some of the brand’s most acclaimed instruments, including the flagship 814ce, Builder’s Edition 814ce and new Gold Label 814e.
The Legacy 800 Series features the 810e Dreadnought and two Jumbos: the 6-string 815e and 12-string 855e. Each model serves up a refined version of the Dreadnought and Jumbo body shapes Bob inherited from Sam Radding—the original owner of the American Dream music shop where Bob and Kurt first met. “I was making my guitars in the molds that Sam had made at American Dream,” Bob recalls. “There was a Jumbo and a Dreadnought. That’s all we had.”
All three Legacy 800 Series guitars feature one of Bob’s favorite tonewood combos. Solid Indian rosewood back and sides are paired with a Sitka spruce top, yielding warm lows, clear trebles and a scooped midrange.
Aesthetic appointments include a three-ring abalone rosette, mother-of-pearl Large Diamond inlays, white binding around the body and fretboard, and Bob’s “straight-ear” peghead design. Both Jumbo models also showcase a mustache-style ebony bridge—a nod to Bob’s early Jumbo builds.
Legacy 810e
The 810 Dreadnought holds a special place in Bob Taylor’s heart. “My first 810, the one I made for myself, was a thrilling guitar for me to make,” he says. “It’s the one and only guitar I played. It didn’t matter how many guitars we made at Taylor, that’s the one I took out and played.” The Legacy 810e brings back that bold, room-filling Dreadnought voice along with the easy playability expected from a Taylor.

Legacy 855e
Taylor’s first 12-strings found an audience in 1970s Los Angeles. “I was making guitars that would find their way to McCabe’s in Santa Monica and Westwood Music,” Bob says, “and these guitars were easy to play. Twelve-strings were a popular sound in that music. It was a modern country/folk/rock music genre that was accepting our guitars because they were easy to play. They also liked the sound of them because our guitars were easier to record.” The Legacy 855e, with its resonant Jumbo body, slim neck and gorgeous octave sparkle, carries that tradition forward.

Legacy 815e
The Legacy 815e revives Taylor’s original Jumbo 6-string, delivering a big, lush sound with beautifully blooming overtones.
Legacy Grand Auditoriums
In the early 1990s, Bob Taylor heard a consistent refrain from dealers: “Not everybody wants a dreadnought guitar anymore.” Players were asking for something with comparable volume but different proportions—something more comfortable, yet still powerful. This feedback inspired Bob to design a new body style with more elegant curves, more accommodating proportions and a balanced tonal response. The result was the Grand Auditorium, which Taylor introduced in 1994 to celebrate its 20th anniversary.
Thanks to its musical versatility and easy playability, Bob’s Grand Auditorium attracted a wide variety of players. “We came into our own with our Grand Auditorium,” he says. “People were describing it as ‘all around.’ It’s a good strummer and good for fingerstyle, but it’s not totally geared toward strumming or totally geared toward fingerstyle.” Also referred to as the “Swiss-Army Knife” of guitars or the “Goldilocks” guitar, the GA quickly became a favorite among guitarists across playing styles, musical genres and different playing applications including recording and live performance. “That guitar made studio work successful,” Bob says. It gained a wider fanbase with the debut of the “ce” version, which introduced a Venetian cutaway and onboard electronics. “That became one of our hallmarks,” says Bob. “If you want to plug in your guitar, buy a Taylor.”
Today, the Grand Auditorium is Taylor’s best-selling body shape.
The Legacy Collection features two cedar-top Grand Auditoriums inspired by past favorites: the mahogany/cedar 514ce and rosewood/cedar 714ce. Both models incorporate Bob’s original X-bracing pattern for a tonal character reminiscent of their 1990s and 2000s counterparts. Shared aesthetic details include a green abalone three-ring rosette, ebony bridge pins with green abalone dots, a faux-tortoiseshell pickguard and Taylor gold tuning machines.

Legacy 514ce
The Legacy 514ce features solid mahogany back and sides paired with a Western Red cedar top, yielding a punchy midrange and dry, woody sonic personality that pairs beautifully with cedar’s soft-touch sensitivity and warmth. It’s a standout choice for fingerstyle players and light strummers who crave nuance and depth. Distinct visual details include faux-tortoise body and fretboard binding, black-and-white top trim, and mother-of-pearl small diamond fretboard inlays.

Legacy 714ce
The Legacy 714ce also features a cedar top, this time matched with solid Indian rosewood back and sides. The result is a richly textured sound with deep lows, clear trebles and a warm, mellow response. Inspiring as it is, this specific wood pairing isn’t currently offered in any other standard Taylor model. Additional aesthetic details include green abalone dot fretboard inlays, black body and fretboard binding, and black-and-white “pinstripe” body purfling.
While the Legacy Collection spotlights Taylor’s past, newer models from the Gold Label, Builder’s Edition and Somos Collections show the company’s legacy is always evolving. Explore the Legacy Collection at taylorguitars.com or visit your local authorized Taylor dealer.
