Boss Slicer
boss.info
One of my favorite gear discoveries in recent years is the original Boss Slicer SL-20. A friend hipped me to its wild percussive magic and what I call “big vibe.” When the first dual-pedal version came out as part of the company’s 20 series, I was under the impression it was a fancy tremolo. That might be the closest classic guitar effect, but the Slicer lives in its own world: The effect chops a signal into preset rhythmic patterns and applies filters and pitch shifters to create everything from propulsive grooves and melodies to glitchy, warbled tones.
Lead parts played in the single and dual settings with the tempo cranked and a lower attack setting evoke a broken-Leslie kind of sound, especially in 3D modes.
The Slicer is a unique effect that’s more in line with what you might find on synths and drum machines than a pedalboard. That, plus an original production run that lasted just a few years, has made it kind of a deep-cut, sleeper favorite. What a surprise, then, that Boss is reissuing the effect in their standard—and much more compact—enclosure.. Even better, the new SL-2 features deeper functionality. So, does it live up to the hype surrounding the original?
Clip 1 – High attack and duty settings, single type.
Clip 2 – High attack and low duty settings, full wet, harmonic type.
Clip 3 – Low attack and high duty settings, tremolo type.
Clip 4 –High attack and low duty, various tempo settings, sfx type.
Clip 5 – Example of how the Slicer can fit into a track. Recorded with two guitars (each with various other effects) each with different Slicer modes (rhythm is stereo, lead is mono).
Deep Functionality, Limited Space
The SL-2 fits a lot of functionality in very little space. It would be impressive just to squeeze all the features of the much larger original unit into the new one. Yet the SL-2’s 88 preset rhythms exceed the original’s 50, and they can be swapped out via USB with Boss’ Tone Studio app. Two stacked knobs cover balance (mix) and tempo as well as attack and duty (sample length). Another single-function knob selects effect type. These include options for a single signal-slicing path, dual signal-slicing paths, tremolo, a harmonic mode (pitch modulated rhythmic patterns), and an SFX mode (multiple effects on each pattern). Another knob selects 11 possible variations on each effect. The Slicer also features dual-jack stereo ins and outs, a MIDI input for syncing with external devices, and an expression/footswitch input.
That extensive list still doesn’t cover all the Slicer’s functions. And to access the rest, things get trickier. Using the pedal’s stereo functionality is critical to making the most of the effect, but to access those seven settings, you may need to keep the manual nearby. For example, if you turn the first four knobs to the right, the type knob to the eighth position, and power up while holding down the footswitch, you can use the variation knob to choose a corresponding stereo setting. Sound confusing? It can be. And there are several of those footswitch tricks to master. Another example: you can set the output volume can range from -7 dB to a very hot 20 dB, which is helpful. But as I learned the hard way, you can easily set the too hot, and it can only be adjusted by holding down the footswitch and turning the tempo knob, which gives you no visual reference for the setting. You’ll also do a lot of footswitch tapping to access tap-tempo settings.
Flying Blind Is Fun
The best way to understand what the Slicer is capable of is to try everything. It’s not particularly intuitive, and it can feel hard to discern differences in some sounds. But there’s some method to the madness. Starting with the relatively straightforward single setting—which chops the signal without additional effects—and trying each variation explains a lot. But there’s no comprehensive list of what effects or rhythms each setting will feature, so you’re flying blind when you work through the variation and type knobs. This led to lots of fun discoveries, though. And I rarely failed to find a pattern that inspired something new in my playing.
Plugging into a stereo rig opens up the Slicer’s capabilities. There are seven stereo settings: fixed (both amps get the same signal), efx/dir (wet/dry), random, ping-pong, auto (which pans across the stereo field), 3D cross, and 3D rotation. The two 3D settings are the most psychedelic, creating the illusion of a forward/backward kind of movement as sounds pan across the field. Any of these settings can change the feel and impact of a pattern or setting, so there’s a lot of room for experimentation.
Inspiration Machine
With such a wide range of capabilities, the Slicer is an inspiration machine, and it can be used in a lot of ways. For the most part, I found myself playing sparsely and letting the Slicer do most of the work, especially when using delay or reverb.
Each effect type offers a wide range of fun. Using harmonic and tremolo effects with slow to medium tempos creates lots of ambient space. Using the ping-pong stereo setting, sometimes feels like multiple guitars. Lead parts played in the single and dual settings with the tempo cranked and a lower attack setting evokes a broken-Leslie kind of sound, especially in 3D modes. But for recording, I preferred this kind of sound in mono, where I captured more direct, glitchy sounds.
The Verdict
The Slicer is a fun effect, and if you’re into exploring ambient ideas, glitchy rhythms, minimalism, or any other kinds of sounds with room for movement, you’ll probably find sounds you love. You also might find new ideas to refresh your playing, like I did, which I think is the ultimate reward. The many pedal and knob combinations that you’ll need to remember in order to access key features can make the SL-2 confusing. I’d prefer the larger footprint of the original with the added functionality of the new model. But at $169, there’s not much room for complaint. The SL-2 is a powerful, creative effect that delivers.

Warm Audio introduces the Fen-tone, a modern ribbon microphone inspired by a classic 50s Danish design.
Warm Audio, the industry-leading manufacturer of classic-inspired professional recording products, microphones, and guitar pedals, today introduces the Fen-tone, an instrument ribbon microphone inspired by a classic 50s Danish design, but built with modern components to deliver powerful bass & rich midrange, true to the sound profile of the most sought-after small-format ribbon microphone. Premium components, including a custom Japanese ribbon, Neodymium magnet, and CineMag USA transformer, along with a 26 dB JFET in-line preamp that enables active use with low-gain preamps ensure that the Fen-tone captures the most popular tones heard on guitars, overheads, horns, and more. The Fen-tone is available as a single mic ($699 | 749 € incl. VAT | £639 incl. VAT) and stereo pair ($1199 | 1349 € incl. VAT | £1159 incl. VAT), available now at authorized retailers worldwide.
“This style of microphone has been around for a long time and the tone has evolved since the original, we're excited to deliver an affordable version of its most contemporary tones,” said Bryce Young, founder and President of Warm Audio. “We’re all familiar with the body style of this mic, but not everyone knows it originally comes from a design from the 1950s. While other B&O-inspired designs have used upgraded ribbons & components like ours to deliver that guitar tone we all know & love, we’ve also upgraded the original switch that cycled between various modes for “Talk”, "Music", and “Orchestra”, to now being an active inline preamp to offer even more value. We revived the trademark to keep it authentic to its history while bringing the Warm formula of premium components to the build to deliver today’s most sought-after guitar & instrument tones.”
Like the original design, the Warm Audio Fen-tone recreates the popular, pencil-style design with ventilated sides that can easily be placed in crowded recording environments. Unlike the original 1950s mic, the Warm Audio Fen-tone features modern upgrades including a custom Japanese ribbon, rare-earth Neodymium magnet, and custom CineMag USA transformer to deliver the iconic ribbon tones made popular in contemporary music.
The Fen-tone, with its Figure-8 polar pattern, excels on loud sources that require detail while handling high SPLs, like electric guitar cabs, overheads, and horns. The upgraded components in Fen-tone deliver intricate midrange detail that helps guitars shine in dense mixes. In addition to the bass and midrange emphasis, Fen-tone shows off its warm “forgiving” tone by taming top-end harshness above 15 kHz for smooth presence without exaggerated sibilance or harshness.
The Warm Audio Fen-tone takes the value a step further by adding an all-analog 26 dB JFET in-line preamp, allowing for active use. This feature is critical for those users who plan on plugging their ribbons directly into audio interfaces or inferior preamps without volume, tone, and frequency loss. This active circuit is true bypass and does not impact the integrity of the passive ribbon mic circuit.
The Fen-tone is available as a single mic ($699 | 749 € incl. VAT | £639 incl. VAT) and stereo pair ($1199 | 1349 € incl. VAT | £1159 incl. VAT), available now at authorized retailers worldwide.

The Mick Ronson Cry Baby Wah, meticulously recreated from his own pedal, offers fixed-wah tones with a custom inductor for a unique sound.
The Mick Ronson Cry Baby Wah taps into the vibrant, melodic character of one of rock ’n’ roll’s most gifted songwriters. Few guitar players have been able to combine a keen musical instinct with a profound grasp of how to bring a composition together like Mick Ronson. Laden with expressive resonance, his arrangements layered deliberately chosen tones and textures to build exquisite melodies and powerful riffs. The Cry Baby Wah, set in a fixed position to serve as a filter, was key to the tone-shaping vision that Ronson used to transform the face of popular music through his work with David Bowie and many others as both an artist and a producer.
We wanted to make that incredible Cry Baby Wah sound available to all players, and legendary producer Bob Rock—a friend and collaborator of Ronson’s—was there to help. He generously loaned us Ronson’s own Cry Baby Wah pedal, an early Italian-made model whose vintage components imbue it with a truly singular sound. Ronson recorded many tracks with this pedal, and Rock would go on to use it when recording numerous other artists. With matched specs, tightened tolerances, and a custom inductor, our engineers have recreated this truly special sound.
“You place the wah, and leave it there, and that's the tone,” Rock says. “It's all over every record he ever made, and I’ve used it on every record since I got it. Dunlop’s engineers spent the time and sent me the prototypes, and we nailed that sound.”
Mick Ronson Cry Baby Wah highlights:
- Tailor-made for Ronson’s signature fixed-wah tones• Carefully spec’d from his own wah pedal
- Custom inductor replicates higher frequency response and subtler peak
- Fast initial sweep with Instant reactivity
- Distinctive EQ curve from period-accurate components
- Special finish inspired by Ronson’s monumental work
The Mick Ronson Cry Baby Wah is available now at $249.99 street from your favorite retailer.

• Open your ears to new influences.
• Understand how to create interlocking rhythm parts.
• Develop a new appreciate for the rhythmic complexity of Wayne Krantz, the effortless bebop of Biréli Lagrène, and the driving force that is David Williams.
The guitar has been a major factor in so many styles of music over the last 70 years, and any experienced musician can tell you that playing any one of those styles with authenticity takes countless hours of dedication. As we learn the instrument, we seek out music that we find inspiring to help guide us toward our voice. The legends we all know in the guitar pantheon have inspired millions of players. In my musical journey over the years, I’ve always been thrilled to discover unique musicians who never attained the same recognition as their more famous counterparts. With so much music at our disposal these days, I thought this group of guitarists deserved a little more spotlight. The inspiration and knowledge they have provided me were paramount in my development, and I wouldn’t be the player I am without them.
Biréli Lagrène’s Bombastic Bop
Standards was the first jazz guitar record I really listened to, and his playing on this entire album is devastating. There is so much groove, joy, and ferocity in every note. The way he lays ideas out on the fretboard made a lot of sense to me, his rhythms were intentional and clear, and it was surprisingly easy to dig into as a rock guitarist at the time. He has an extensive catalog of jazz, gypsy jazz, and fusion records with some of the best in the world, and he’s also a killer bass player who can sing just like Frank Sinatra! Ex. 1 is over the first eight measures of “Stella by Starlight.” I stole so much vocabulary from this solo that I can still play bits from memory 20 years later. Lagrène’s treatment of two-measure chunks to play his ideas was significantly helpful. Whether it was an engaging rhythmic phrase, constant eighth-notes, or just cramming in as much as he could, I stopped worrying so much about catching every chord change after I learned this one.

Old-School Swing!
George Barnes is a unique jazz guitarist who was a contemporary of Charlie Christian, Johnny Smith, and Django. A significant part of his early work was writing and arranging for radio and television, for NBC, and he also wrote the very first electric guitar method book in 1942. A friend in Austin gave me two CDs of his: a collection of his playing from the Plantation Party radio show and an overview of his octet recordings. The octet recordings sound like unhinged cartoon music with guitar and orchestral instruments and are highly enjoyable. Ex. 2 is a line I lifted from a recording of him playing “Ain’t Misbehavin.” It was one of the hippest endings I have ever heard on a jazz tune, and although I can’t find the recording anywhere, I still use it all the time. I love the intention in George Barnes’ playing. Swinging and mischievous, he always sounds like he was having fun.

“Thrilling” Rhythm Solos
David Williams is one of the greatest rhythm players of all time. He is responsible for most of the memorable guitar moments on Michael Jackson’s records, and all his parts have an infectious nature. He is the primary reason I got interested in rhythm guitar, and he is still an inspiration on that front. One of my favorite examples of his playing is the breakdown in Michael Jackson’s “Thriller” (where Vincent Price does the rap). His signature thunderous right-hand approach to single-note rhythm parts is in full effect, and the natural accents between the two rhythm parts are infectious on their own but weave perfectly together. Ex. 3 is my interpretation of two interlocking parts in this style. He’s said in interviews that his concept as a player was to develop “rhythm solos” that could stand out front in a song, and this is a perfect example of that.

(Better than) Average Riffs
Though Hamish Stuart is most known for being an original member of the Average White Band, the singer/guitarist/composer/producer also did extensive work with heavyweights such as George Benson, Paul McCartney, Chaka Khan, and Aretha Franklin. Though AWB was still working until 1983, Hamish was doing sessions with various artists as a sideman in the early ’80s, including this excerpt from “Move Me No Mountain” off Chaka Khan’s Naughty from 1980 (Ex. 4). I’ve always loved the interplay between these two parts, range-wise and rhythmically. The lower pick line hits some unusual 16th-note placements, and the higher dyads have a churn to them that is amazing. Both parts together feel different rhythmically from anything I have ever heard but sound so cool and unique.

Wayne Krantz
Wayne Krantz is one of those guys that hit me like a lightning bolt. Upon hearing him, I felt like I had “permission” to play more with the fingers of my right hand, use jagged and intentional rhythms, and above all, to play more naturally. Wayne has always played like himself. His control over rhythm and articulation alone is legendary, not to mention the vast body of unique work he has created. Ex. 5 is an excerpt from the only solo I ever learned of his, from “Infinity Split” off 1999’s Greenwich Mean. I love this solo because it is incredibly engaging rhythmically and melodically, but almost 100 percent inside the harmony. This solo taught me more about rhythmic placement and articulation than anything.
Ex. 5
Wayne Krantz - Infinity Split
Though I could only grab a certain percentage of these guys’ “vocabulary,” learning these parts over the years helped me find my sound. The result was an attempt to emulate some of their musicality in my way, rather than outright imitating them. Anything you hear that grabs your interest is probably worth sitting down and figuring out. While we might not mention the guitarists above alongside Hendrix or Van Halen, they have all done their part to put a brick in the cathedral, furthering music, and the instrument.
