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!

John Petrucci, St. Vincent, James Valentine, Steve Lukather, Tosin Abasi, Cory Wong, Jason Richardson, Fluff, and more are donating instruments for contributors, and contributions are being accepted via this LINK.
The L.A. wildfires have been absolutely devastating, consuming more than 16,200 structures, and tens of thousands of people–including many members of the LA music community–have been displaced, as well as 29 persons killed. Historic gear company Ernie Ball has stepped up with a large-scale fundraiser, for MusicCares and the Los Angeles Fire Department Foundation, to assist those impacted by the fire and responders on the front line. The company kicked off the initiative with a $50,000 donation.
“We are absolutely crushed by the devastation Los Angeles has endured over the past few weeks,” CEO Brian Ball said in a statement. “As a California-based company with origins as a small retailer in LA County, seeing the impact of these fires in our community is heartbreaking.
Message from Tim Henson
Tim Henson is donating one of his own Ibanez TOD10N guitars for the cause.
“That’s why we’re partnering with our family of artists to give back in a unique way. In addition to our donation, Ernie Ball artists are stepping up to donate personal guitars and gear—truly one-of-a-kind pieces that money can’t buy. Here’s how you can help: Donate any amount and we will randomly give these items away. Every dollar goes directly toward helping those affected by these devastating fires. If you can’t donate, sharing this message can still make a huge impact,” Ball declared.
The fundraiser will continue until February 14.

The past year was full of new sounds and discoveries. Ariel Posen and Jeremy Jacobs join the PGteam to highlight what popped out to them over the last 12 months.
Q: What was your biggest guitar discovery of 2024?
Guest Picker - Ariel Posen
A: Twenty-twenty-four was a year of discovery and re-discovery for me. I tend to come back to records and artists that I haven't listened to in a long time and get back into them with a new-found excitement. In regards to guitar discovery, at the end of 2023 I got into Paramore for the first time, specifically their last album, This is Why. I don't really listen to guitar music these days, but I'm always infatuated by the extreme detail of finely crafted guitar parts that help serve the song, and that album is full of that stuff. In terms of rediscovery, I spent a lot of time digging back into early George Harrison, Christopher Cross, and some specific Steely Dan records. Seems to be a theme there. I love all that stuff but haven't really given it time in a while; that changed this past year.
Obsession: Doechii. Watch her Tiny Desk video. She's incredible and the band is too. I get goosebumps every time I watch it, and I watch it once a day.
Reader of the Month - Jeremy Jacobs
A: I was turned on to Mk.Gee after seeing his performance on SNL and immediately fell in love with the vibe. I’m always trying to keep an ear to the ground for new, innovative guitar sounds, and his unique approach to creating guitar tones was really refreshing and inspiring. I love the blend of retro ’80s synth sounds and modern digital guitar production.
Obsession: Jim Lill’s video series on YouTube experimenting with guitar tone. He’s like the Mythbusters of the guitar community and it’s really shaking things up! He’s taking a very scientific deep dive into commonly held beliefs about what makes certain equipment “sound good” and has returned some truly shocking results. I’m thinking about guitar gear in a totally different way thanks to his work.

A: Big delays and reverbs finally got to me in 2024. Typically, I would favor a modest spring or room setting, but a few gigs this year pushed me into more ambient territory. It’s incredible how the sound of space affects your touch on the instrument. My playing has become more melodic and intentional—but I’m still not digging the shimmer vibe.
Obsession: Noel Johnston’s YouTube videos from his Creative Fundamentals class have been warping my brain. Fair warning: They do require a bit of theoretical knowledge to get the most out of them. However, his triad workouts are a great way to start to visualize different shapes all over the neck—no matter what key.

A: Last year, I discovered germanium. This isn’t strictly true; I’ve used germ pedals in the past, but I never connected with the transistors until I picked up the Death by Audio Germanium Filter. Now, all I want is sweet, gnarly, splatty germanium grossness on whatever I play. The problem is it doesn’t really fit with my band’s sound. I predict many arguments in 2025.
Obsession: Figuring out ways to make, share, and celebrate music outside of the too-powerful platforms that have monopolized our arts and culture. Thankfully, there are loads of people way smarter than me working with each other to build new networks and meanings for music, including some that would be musician-owned. The future is bright—if we want it!
The author found this one-of-a-kind tremolo/vibrato/sound-altering modulation box at Quattro Music Company in Thomas, West Virginia.
Producer and roots-guitar veteran Michael Dinallo pens his unabashed love letter to tremolo, with fond recollections of vintage Fender and Gibson amps, Dunlop’s TS-1, and a one-of-a-kind mystery modulator.
Tremolo is my favorite effect to modulate a guitar’s sound (and I love vibrato, too). I love it so much that it’s part of the moniker of the production team I had with the late Ducky Carlisle—the Tremolo Twins—as well as our Trem-Tone Records label. You might recognize Ducky from his many engineering credits, including Buddy Guy, or our work together on albums like Stax veteran Eddie Floyd’s heralded Eddie Loves You So, from 2008.
For me, the golden period of tremolo was the early 1960s. The brown-panel Fender amps of that period have astounding harmonic tremolo, as do the Gibson amps from that period. I have a 1963 Gibson GA-5T Skylark that has a tremendous tremolo circuit. I used that amp for all the guitar parts I cut on my new album, The Night’s Last Dance,as well as all the records I’ve worked on over the last four years, either as producer or player. My favorite, though, is the 1963 2x10 Fender Super—also a brown-panel amp. It can be so soupy that, if multi-tracked, it can almost induce seasickness.
But there are so many choices and classic sounds. The Magnatone and Lonnie Mack jump to mind, or the use of a Leslie cabinet for guitar, which is another sound I love as both player and producer. Two of the most distinct and famous uses of tremolo, to my ears, are Link Wray’s “Rumble” and Reggie Young’s arpeggiating opening chord on “The Dark End of the Street” by James Carr. There is a shimmery quality to big chords drenched in a slow tremolo, especially if the part is doubled. From a production standpoint, it adds depth to a track, even if it’s mixed way in the back.
Let’s talk about doubling a tremolo part. Once in a while you can get lucky and have the amp cycle the wave at just the right time as you hit the record button. But most often not. Usually this is not a big deal and adds to the depth of the bed part being recorded. Sometimes, though, it has to be a tight double. That’s when I’ve spent much time guessing at the cycling and trying to hit it just right. It’s a blast when you do.
One of my favorite experiments with tremolo was setting up two amps—a brown-panel Fender Vibroverb and a brown-panel Fender Concert—in a V-shape. The amps were set to the same volume and approximately the same tone settings. Using a stereo mic in the middle of the V, we recorded it to one track. We had to keep tweaking the individual tremolo settings in an effort to not have them cancel each other out. But what a huge, lush sound!
“There is a shimmery quality to big chords drenched in slow tremolo, especially if the part is doubled.”
There are many tremolo pedals and recording plugins these days, and they’re all good, but nothing quite captures the sound of an internal tremolo circuit. You can avoid chasing their cycles, too, if a pedal has a tap-tempo function. But what fun is that?
The one tremolo pedal, for me, that comes the closest to an in-amp circuit is the now-vintage Dunlop TS-1. Thirty years ago, I needed a tremolo pedal for my road amp—at the time, a 1994 Fender tweed Blues DeVille. I found Dunlop’s big, honking purple metal box with “tremolo” written across the front in wavy yellow letters. You can get wide, sweeping tremolo or set it to a hard, choppy setting where the volume completely disappears. I’ve used both applications effectively. The hard trem is great for the last chord of a song, especially live, hitting like a boxer sparring with a weighted, hanging bag—especially if you’re diving into a psychedelic ending. And, of course, mixing in other modulation effects, such as flanging or phasing, adds another twist.
I found the most unique tremolo/vibrato/sound-altering modulation box I have at Quattro Music Company in Thomas, West Virginia. It’s not a pedal per se; it’s circuitry housed in a cigar box with so many knobs and switches and variations that I still have not exhausted all the possibilities. It’s a one-off. I was told it was the only tremolo box the inventor made. Combining it with a front-end boost and diming an amp produces otherworldly sounds. I’ve used it on a couple of recordings: “Never, No More (A Reckoning)” by Keith Sykes and me, and “Time Machine” by the Dinallos (where we were joined by Nashville’s famed singing siblings, the McCrary Sisters). With the latter, it’s most obvious as a tremolo device, and on the former it’s as a sound-altering gizmo that enhances the guitar leads.
Of all the toys in the arsenal that guitarists have, I’ve gotta say, long live tremolo!
