PG tests a trio of powerful new designs—from Carl Martin's plug-and-play Octa-Switch Mk3 to RJM's tricked-out Mastermind PBC and Boss' deep-but-accessibly priced ES-8.
We treasure our pedals for the unique tone shaping capabilities they give us—for the individuality they lend to our sounds and music. We also get so attached to those little buggers that it can be hard to consider alternatives.
Such sentimental attachments can make a pedal collection less than the sum of its parts. For one thing, an in-series pedal set up is inherently limited in relation to the possible sounds that set of pedals can make when reshuffled, reordered, and reconfigured. Then there’s the issue of on-the-fly switching. Unless you’re capable of Houdini-meets-Baryshnikov contortions you’ll never be able to switch on five pedals simultaneously.
Pedal switchers make such magic tricks as easy as pressing a single switch. Many switchers eliminate the limitations of in-series pedal setups by enabling the creation of unique pedal sequences via switchable loops. Some also offer features like amp channel/effects switching and MIDI connectivity that help maximize the potential of the pedals that are already the foundation of your sound.
For this roundup, we check out three of the latest switchers: the Carl Martin Octa-Switch MK3, Boss ES-8, and RJM Mastermind PBC. They cover a fairly wide spectrum in terms of cost, functionality, and design emphasis. But each offers the opportunity to relate the pedals you already love in ways you may never have considered or expected.

RJM Mastermind PBC
RJM Music Technology is best known for rack switching devices, and players from Beck to Billie Joe Armstrong to John Petrucci all use the company’s high-end systems. The new, U.S.A.-built Mastermind PBC, however, shrinks RJM’s rack mount technology into a compact format designed to fit on a pedalboard and be more accessibly priced to players without Learjet budgets.The Mastermind PBC is ostensibly a control station for your pedals, but it can do much more than that—certainly more than we can cover in this review. The unit features 10 loops with insert points in between groups, which offers copious routing options. You can even run some pedals straight into the amp and others through your amp’s effects loop.

RJM Music Mastermind PBC

RJM clearly considered just about every scenario pedal junkies are likely to face. So the Mastermind PBC offers simple solutions for the most common problems. While the unit is true bypass, there are three switchable buffers that can be saved as part of any given preset. The last four loops, meanwhile, have an internal mixer so you can route pedals in series or parallel. The Mastermind PBC can also be configured for a stereo setup or for A/B routing to different amps. I took advantage of the latter option and connected one end to my shimmery clean blackface Fender Deluxe Reverb and the other to my Mesa/Boogie Trem-O-Verb. It was a pairing made in heaven.
There is room to store up to 768 presets so it’s very unlikely you’ll run out of space. The readout is sizeable but not too huge—the right balance of compact and easy on the eyes. There’s even a built-in tuner (although there’s no dedicated tuner out on the back panel). Other standout features are USB connectivity, a flash storage option, and PBC Editor (for use on a Mac or PC). One of my biggest gripes with anything multi-effects related is scrolling through screens to adjust every little parameter. The PBC Editor gives you much more control over the Mastermind’s internal control parameters.
Though downloading and hooking up the editor is easy, it’s not immediately intuitive. It took a little bit of time to get my bearings, and I think many guitarists coming from a world of analog pedals will have the same experience. Successfully navigating the editor comes with a significant payoff, however. The level of control is astounding, especially if you use MIDI capable pedals like the Strymon TimeLine or Mobius, or the Line 6 M series. The sound sculpting potential opened up by the editor and the seamless way it will interface with MIDI pedals is enormous.
At $999 street, the Mastermind PBC is the priciest switcher in our roundup, but there’s little sticker shock when you realize how much it can do and the exponential way in which it expands the possibilities of your rig. It’s perfectly suited for a professional touring musician. But the sound shaping possibilities and the excellent MIDI and digital workstation interfacing options could just as easily make it the centerpiece of a home recording rig.

Boss ES-8
I’ve owned several Boss multi-effects units over the years and have always been impressed with how configurable and adaptable they tend to be. Boss’ emphasis on practical, real-world utility and user friendliness remains intact in the ES-8. And it offers a ton of flexibility at a very reasonable price.At a glance, the ES-8 looks like a compact multi-effects unit. But there’s a lot of functionality jammed into a little package. The back panel almost looks like a studio patch bay for all the jacks crammed onto such a small space. All told there’s—count ’em—33 1/4" jacks and a pair of MIDI in/out jacks. There are eight send/return jacks (the seventh provides mono send and stereo return, and the eighth offers stereo send and return), control jacks to let you switch amp channels and turn on reverb, jacks for connecting expression pedals, and a plethora of additional connections. With that many I/Os, real estate is at a premium so it’s vital to use straight 1/4" cables.

Boss ES-8
boss.info
Manual mode lets you turn pedals on and off just like you would on a conventional pedalboard. Memory mode, however, is where the real action is, and here you can access saved loop combinations via 100 banks that provide a total of 800 presets.
At times, you might wonder why there are so many preset options—particularly given how easy the Boss makes it to add effects to existing presets on the fly. Nevertheless, the flexibility afforded by all these options is impressive. And given the Boss’ ability to delve into nuances like effects trails and series and parallel routing (the latter feature in particular can really open up new possibilities for your old effects), you might start crafting presets in the hundreds before you know it!
Thankfully, the Boss is pretty easy to program and edit. Changes in pedal order are represented on the loop structure screen, which provides a very simple numeric representation of the pedal order. Boss has always excelled at creating these kinds of simple interfaces and, in a pedal that can be as complicated as the ES-8, it does wonders in streamlining programming and easing the learning curve. One shortcoming of the readout is that it does not reveal the order of pedals when you select the preset itself. You can only see the order in edit mode. That means you’ll need a pretty good memory, a thorough system of organization, or a lot of practice to navigate a deep library of presets—but that goes for most loopers this complex.
The Boss is thoughtful at the nuts and bolts level, too. Buffers can be turned on and off for each input to compensate for pedals like old wahs and fuzzes that are particular about their positions relative to buffered switches. Better still, these settings can be stored for each preset. It’s a small detail, but it eliminates a lot of the headaches that would ordinarily come with switching pedal order. MIDI capability is useful in cool ways, too. I especially liked the Master BPM, which enables you to assign tempo parameters for compatible effects in a given patch.
There are many switchers on the market, but outside of custom-built units that cost thousands more than the ES-8’s $699 street, you’d be hard pressed to get this level of control over your entire rig at this appealing price.

Carl Martin Octa-Switch MK3
Carl Martin Octa-Switch MK3
Although the Octa-Switch MK2 still feels fresh in our memory, Carl Martin recently released the MK3, a streamlined edition of the popular MK2. At a street price of around $427, it’s easily the most affordable switcher in our roundup.The MK3 is more pedalboard-friendly than the two previous incarnations—primarily because it utilizes two rows of footswitches, rather than one long row. And while Carl Martin has stuffed a lot of functions into less space, the jacks are still spaced out wide enough to patch in the right-angle plugs used for most pedalboard applications (something I wasn’t able to do with the other two switchers in this roundup).
I was a little surprised when I opened the box and didn’t see a power supply. But the Octa-Switch MK3 is compatible with a standard 9V adapter, and I just daisy chained it to my pedalboard’s existing power supply. (Unlike the MK2, the MK3 can’t be powered by batteries.)
The Octa-Switch MK3 offers eight loops (the last loop is stereo) and eight banks—which should be more than enough for most players. In addition to the eight loop footswitches, there’s a switch for bypassing the unit completely.
The MK3 has a decidedly mechanical, analog feel—largely due to the absence of a readout and the eight dip switches above each preset footswitch. The dipswitches correspond to the eight send/returns and the pedal; you route through them. You determine which pedals make up a given preset by turning the dipswitches off or on. I’m not a huge fan of dipswitches, but here the design is more intuitive, and arguably faster, than scrolling through a small screen. On the top corner of the control panel are eight small blue LEDs that correspond to loops 1-8 and light up to show which loop is activated on a selected preset. There are also two rows of dipswitches for external switching of amp channels or amplifier reverb. These, too, can be assigned to work with a selected loop.

Carl Martin Octa-Switch MK3

It took me about a minute to program a relatively simple rig consisting of a Mesa/Boogie Trem-O-Verb and several pedals. For a rhythm preset, I used a Boss CE-2 and Ibanez AD-9 going into the amp’s clean channel. For leads, I created two presets—a Mad Professor Bluebird overdrive/delay going into the amp’s clean channel and an Ibanez TS-9 used as a boost going into the amp’s high gain channel. I also used a Boss TU-2 tuner, though, oddly, there is no dedicated tuner out on the Octa-Switch MK3. The presets all worked flawlessly and switching was immediate and pop free.
The MK3 lacks MIDI, the ability to change the order of pedals in a chain, and the ability to switch on individual pedals while running a preset. But while it may lack some of the features that distinguish and add wow factor to the Boss and RJM, I didn’t mind not having those options. If I knew I’d need an additional boost for a lead preset to suit a different playing environment, I’d simply add the boost to an existing preset or program a new one on the spot. It doesn’t take more than a second to flick the dipswitch. Above all else, the MK3 is fast and easy.
Though it may lack some fancy digital features, the MK3 is capable of a lot more than just switching pedals on and off. You can use it as a killer A/B switcher to route two guitars into two separate amps, with each pair attached to its own group of effects. Just bypass the standard in/out controls and patch everything through the loop jacks.
The mechanical simplicity of the Octa-Switch MK3 is a beautiful thing. The intuitive design means neophytes can get started fast without consulting a manual. And it’s simple enough to make troubleshooting a breeze in performance situations. In an era in which many switchers are as complex as some multi-effects units, the MK3’s what-you-see-is-what-you-get layout cuts through all the frivolities. This bad boy lets you just program the configurations you’ll actually need rather than bog you down with hypothetical possibilities you’ll never actually use.

We know Horsegirl as a band of musicians, but their friendships will always come before the music. From left to right: Nora Cheng, drummer Gigi Reece, and Penelope Lowenstein.
The Chicago-via-New York trio of best friends reinterpret the best bits of college-rock and ’90s indie on their new record, Phonetics On and On.
Horsegirl guitarists Nora Cheng and Penelope Lowenstein are back in their hometown of Chicago during winter break from New York University, where they share an apartment with drummer Gigi Reece. They’re both in the middle of writing papers. Cheng is working on one about Buckminster Fuller for a city planning class, and Lowenstein is untangling Austrian writer Ingeborg Bachmann’s short story, “Three Paths to the Lake.”
“It was kind of life-changing, honestly. It changed how I thought about womanhood,” Lowenstein says over the call, laughing a bit at the gravitas of the statement.
But the moment of levity illuminates the fact that big things are happening in their lives. When they released their debut album, 2022’s Versions of Modern Performance, the three members of Horsegirl were still teenagers in high school. Their new, sophomore record, Phonetics On and On, arrives right in the middle of numerous first experiences—their first time living away from home, first loves, first years of their 20s, in university. Horsegirl is going through changes. Lowenstein notes how, through moving to a new city, their friendship has grown, too, into something more familial. They rely on each other more.
“If the friendship was ever taking a toll because of the band, the friendship would come before the band, without any doubt.”–Penelope Lowenstein
“Everyone's cooking together, you take each other to the doctor,” Lowenstein says. “You rely on each other for weird things. I think transitioning from being teenage friends to suddenly working together, touring together, writing together in this really intimate creative relationship, going through sort of an unusual experience together at a young age, and then also starting school together—I just feel like it brings this insane intimacy that we work really hard to maintain. And if the friendship was ever taking a toll because of the band, the friendship would come before the band without any doubt.”
Horsegirl recorded their sophomore LP, Phonetics On and On, at Wilco’s The Loft studio in their hometown, Chicago.
These changes also include subtle and not-so-subtle shifts in their sophisticated and artful guitar-pop. Versions of Modern Performance created a notion of the band as ’90s college-rock torchbearers, with reverb-and-distortion-drenched numbers that recalled Yo La Tengo and the Breeders. Phonetics On and On doesn’t extinguish the flame, but it’s markedly more contemporary, sacrificing none of the catchiness but opting for more space, hypnotic guitar lines, and meditative, repeated phrases. Cheng and Lowenstein credit Welsh art-pop wiz Cate Le Bon’s presence as producer in the studio as essential to the sonic direction.
“On the record, I think we were really interested in Young Marble Giants—super minimal, the percussiveness of the guitar, and how you can do so much with so little.”–Nora Cheng
“We had never really let a fourth person into our writing process,” Cheng says. “I feel like Cate really changed the way we think about how you can compose a song, and built off ideas we were already thinking about, and just created this very comfortable space for experimentation and pushed us. There are so many weird instruments and things that aren't even instruments at [Wilco’s Chicago studio] The Loft. I feel like, definitely on our first record, we were super hesitant to go into territory that wasn't just distorted guitar, bass, and drums.”

Phonetics On and On introduces warm synths (“Julie”), raw-sounding violin (“In Twos”), and gamelan tiles—common in traditional Indonesian music—to Horsegirl’s repertoire, and expands on their already deep quiver of guitar sounds as Cheng and Lowenstein branch into frenetic squonks, warped jangles, and jagged, bare-bones riffs. The result is a collection of songs simultaneously densely textured and spacious.
“I listen to these songs and I feel like it captures the raw, creative energy of being in the studio and being like, ‘Fuck! We just exploded the song. What is about to happen?’” Lowenstein says. “That feeling is something we didn’t have on the first record because we knew exactly what we wanted to capture and it was the songs we had written in my parents’ basement.”
Cheng was first introduced to classical guitar as a kid by her dad, who tried to teach her, and then she was subsequently drawn back to rock by bands like Cage The Elephant and Arcade Fire. Lowenstein started playing at age 6, which covers most of her life memories and comprises a large part of her identity. “It made me feel really powerful as a young girl to know that I was a very proficient guitarist,” she says. The shreddy playing of Television, Pink Floyd’s spacey guitar solos, and Yo La Tengo’s Ira Kaplan were all integral to her as Horsegirl began.

Recently, the two of them have found themselves influenced by guitarists both related and unrelated to the type of tunes they’re trading in on their new album. Lowenstein got into Brazilian guitar during the pandemic and has recently been “in a Jim O’Rourke, John Fahey zone.”
“There’s something about listening to that music where you realize, about the guitar, that you can just compose an entire orchestra on one instrument,” Lowenstein says. “And hearing what the bass in those guitar parts is doing—as in, the E string—is kind of mind blowing.”
“On the record, I think we were really interested in Young Marble Giants—super minimal, the percussiveness of the guitar, and how you can do so much with so little,” Cheng adds. “And also Lizzy Mercier [Descloux], mostly on the Rosa Yemen records. That guitar playing I feel was very inspiring for the anti-solo, [a technique] which appears on [Phonetics On and On].”This flurry of focused discovery gives the impression that Cheng and Lowenstein’s sensibilities are shifting day-to-day, buoyed by the incredible expansion of creative possibilities that setting one’s life to revolve around music can afford. And, of course, the energy and exponential growth of youth. Horsegirl has already clocked major stylistic shifts in their brief lifespan, and it’s exciting to have such a clear glimpse of evolution in artists who are, likely and hopefully, just beginning a long journey together.
“There’s something about listening to that music where you realize, about the guitar, that you can just compose an entire orchestra on one instrument.”–Penelope Lowenstein
“In your 20s, life moves so fast,” Lowenstein says. “So much changes from the time of recording something to releasing something that even that process is so strange. You recognize yourself, and you also kind of sympathize with yourself. It's a really rewarding way of life, I think, for musicians, and it's cool that we have our teenage years captured like that, too—on and on until we're old women.”

Last summer, Horsegirl gathered at a Chicago studio space to record a sun-soaked set of new and old tunes.
Featuring torrefied solid Sitka Spruce tops, mahogany neck, back, and sides, and Fishman Presys VT EQ System, these guitars are designed to deliver quality tone and playability at an affordable price point.
Cort Guitars, acclaimed for creating instruments that exceed in value and quality, introduces the Essence Series. This stunning set of acoustic guitars is designed for musicians looking for the quintessential classic acoustic guitar with fabulous tone all at an exceptional price point. The Essence Series features two distinct body shapes: The Grand Auditorium and the OM Cutaway. Whatever the flavor, the Essence Series has the style to suit.
The Essence-GA-4 is the perfect Grand Auditorium acoustic. Wider than a dreadnought, the Essence-GA-4 features a deep body with a narrower waist and a width of 1 ¾” (45mm) at the nut. The result is an instrument that is ideal for any number of playing styles: Picking… strumming… the Essence GA-4 is completely up for the task.
The Essence-OM-4 features a shallower body creating a closer connection to the player allowing for ease of use on stage. With its 1 11/16’th (43mm) nut width, this Orchestra Model is great for fingerpickers or singer/guitarists looking for better body contact for an overall better playing experience.
Both acoustics are topped with a torrefied solid Sitka Spruce top using Cort’s ATV process. The ATV process or “Aged to Vintage”, “ages” the Spruce top to give it the big and open tone of older, highly-sought-after acoustics. To further enhance those vintage tones, the tops bracing is also made of torrefied spruce. The mahogany neck, back, and sides create a warm, robust midrange and bright highs. A rosewood fingerboard and bridge add for a more balanced sound and sustain. The result is amazing tone at first strum. 18:1 Vintage Open Gear Tuners on the mahogany headstock offer precise tuning with vintage styling. The herringbone rosette & purfling accentuates the aesthetics of these instruments adding to their appeal. Both acoustics come in two choices of finish. Natural Semi-Gloss allows the Sitka spruce’s natural beauty to shine through and classic Black Top Semi-Gloss.
A Fishman® Presys VT EQ System is installed inside the body versus other systems that cut into the body to be installed. This means the instrument keeps its natural resonance and acoustic flair. The Presys VT EQ System keeps it simple with only Volume and Tone controls resulting in a true, crisp acoustic sound. Lastly, Elixir® Nanoweb Phosphor Bronze Light .012-.053 Acoustic Strings round out these acoustics. This Number 1 acoustic guitar string delivers consistent performance and extended tone life with phosphor bronze sparkle and warmth. The Essence Series takes all these elements, combines them, and exceeds in playability, looks, and affordability.
