This New Practice Amp is so Stunning, You'll Want to Display it in Your Living Room
Positive Grid's new Spark Pearl – a limited version of their best-selling smart amplifier – delivers both brilliant looks and tones
Picture this. You've just come home from a long day at work. It's time to kick back, plug in, and let off some steam while playing your guitar.
How do you typically play for fun while at home? Lug out your half stack? Grab that tin-y sounding practice amp from the closet that you purchased 20 years ago?
With Spark Pearl, there's a way to practice, jam and record in style – right there in your living room – and sound great while doing it with access to an endless well of inspiring tones. Positive Grid's brilliantly limited version of one of the industry's most popular desktop amplifiers, Spark Pearl offers all of the same crowd-pleasing smart features of the original amp, like Smart Jam, Auto Chords, and access to over 10,000 tones.
Plus, with its snowy white tolex, gold piping and contrast-stitched custom strap, you'll proudly display it in your living room or home studio. (I mean, just look at that thing!) Spark Pearl is a Bluetooth speaker too, perfect for streaming your favorite tunes to liven up any social gathering.
On its own, Spark Pearl offers seven high-quality amp settings to choose from, including hi-gain, clean and crunch. These sounds can be customized further with bass, mid and treble tone stack controls, plus mod, delay and reverb effects. Users can also save up to four tones directly to the amp for later use.
However, Spark Pearl's inspiring tone creation capabilities go way beyond the amp itself. With the companion Spark app, players can access the same tone engine that put the original Spark on the map. Here, guitarists can craft tones virtually using 30 tube amps and 40 effects powered by Positive Grid's BIAS technology, for perfecting that signature tone of their favorite player or discovering a unique sound of their own. They can also share their sounds using Positive Grid's online ToneCloud, which is home to over 10,000 tones created by famous guitarists, session players, engineers and producers from around the world.
Most pieces of guitar gear are designed with one person in mind -- the guitarist. As a result, thousands of amps and pedals have suffered the fate of being banished to basements, home offices and other designated practice areas. With a compact design highlighted by custom white tolex and gold piping, Spark Pearl looks like it could be a piece of modern home décor just as much as a guitar amp. So whether you want to jam in your living room, bedroom, kitchen, or anywhere else in your house, take comfort knowing that you'll look good in the process - so much so that you'll finally not get yelled at for leaving your gear sitting out in the living room!

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.

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.
