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!

Ungodly, sinister, and maliciously menacing guitar tones erupt from the Kentucky hardcore band’s 7-string Ibanez models, providing the soundtrack to the summer’s biggest mosh pits and nastiest breakdowns.
If hell had a guitar tone, it’d be what Knocked Loose’s Isaac Hale and Nicko Calderon conjure up from their Ibanez 7-string beasts. The band’s mission since day one has been to pummel listeners with the most extreme form of hardcore music. Over the past decade they’ve throttled through all limits, making each breakdown, each riff, each scream, and each performance outdone by the next. A more recent (and seemingly) conflicting goal has been to infect the mainstream with their brutality. Their brand-new third album, You Won't Go Before You're Supposed To, paired them with pop producer Drew Fulk (Kevin Gates, NLE Choppa, Disturbed, Lil Wayne), and over the last two years, they’ve played Coachella and Bonnaroo, partnered with hip-hop duo $uicideboy$ for a sold-out tour, and were announced as direct support for Slipknot’s 25th anniversary tour. Both of the band’s goals are being accomplished, as their sound has never been more punishing or popular.
Before Knocked Loose’s sold-out show at Nashville’s Marathon Music Works, guitarists Isaac Hale and Nick Calderon invited PG’s Perry Bean onstage for a fresh conversation about their updated mercenary squad. During our time with the Hale and Calderon, we learn about their custom 7-string Ibanez doom brooms, Hale explains moving on from tube amps and pedalboards to Quad Cortex units and MIDI switching, and Calderon details finding his place in the band and adjusting to an extra low-B string.

Isaac's Iceman
When we spoke with the Oldham County crew five years ago, cofounding guitarist Isaac Hale was using an Ibanez RGDIX7MPB. He’s still in the Ibanez family and strictly uses 7-string instruments, but he’s gravitated to the iconic Iceman shape for his pit-provoking duties. This white custom configuration features a lighter nyatoh body, DiMarzio Fusion Edge 7 ceramic humbuckers, a single master volume knob, and a smaller neck profile. If all goes well, he uses this guitar onstage all night. He uses a custom set of D’Addario NYXL strings with the current low-B string a thick .070 gauge.
Nicko's No.1
Before joining Knocked Loose in 2020, guitarist Nicko Calderon had never played a 7-string guitar. (“It was a huge learning curve for me,” he says.) Like Isaac, if all goes as planned, Nicko will only play the above Ibanez Prestige AZ24047 all set. One of the requests Nicko had for Ibanez was to keep it simple with a single Seymour Duncan Nazgul Bridge 7-string humbucker and a lone volume knob. He goes with a D’Addario NYXL (.011–.064) 7-string set.
Beautiful Backups
If things go sideways, both Isaac and Nicko have safety nets: Hale has a custom-painted Ibanez Iron Label Iceman ICTB721, and Calderon goes with another single-pickup Ibanez Prestige AZ24047.
Less Is More
Both guitarists have downsized to the Neural DSP Quad Cortex, and they have a pair of mirrored setups for both on and offstage. Hale and Calderon are both modeling 5150 III heads, but Calderon is going with the EL34 flavoring for a slightly different sonic distinction. Core sounds are built off the 5150 IIIs and other ingredients sprinkled in throughout the set include some slight chorus, heavily modulated “evil chorus” with an added semitone above the base sound, and each has an Electro-Harmonix (in the rack) that provides a layered octave sound for pure chaos. The EHX Freeze pedal onstage is put in place so they can hold a note and tune underneath it. They roam the stage untethered thanks to the Shure GLXD16+ digital wireless guitar pedal system.
Bring the Pain
The two Quad Cortex units work with Seymour Duncan PowerStage 200 amps to hit Orange PPC412-C cabs onstage that are loaded with Celestion Vintage 30 speakers.

Watch Tom Butwin demonstrate Keeley’s super versatile 4-in-1 overdrive pedal series: the Blues Disorder, Angry Orange, Super Rodent and Noble Screamer.
The newest pedals from Keeley Electronics each offer two independent effects featuring classic overdrive/distortion circuits. The effects are carefully paired together and allow you to mix-and-match their respective clipping sections (one hard clipping and one soft clipping) and tone sections. The Noble Screamer combines a Nobels ODR-1 (hard clip) and Ibanez Tube Screamer (soft clip). Angry Orange unites a mighty Big Muff (soft clip) and Boss DS-1 (hard clip). Blues Disorder pairs a Marshall Blues Breaker (soft clip) with a Fulltone OCD (hard clip). And the Super Rodent combines a Boss SD-1 (soft clip) with the venerable Rat pedal (hard clip). The fun really begins when you experiment with mashups: you can link the overdrive section from Circuit A with the tone section of circuit B, and vice versa. These “hyrbrid” modes offer unusual and unexpected delights. Suddenly you have four pedals in one.
Based in Oklahoma, industry icon Robert Keeley and his team have channeled 25-plus years of know-how into this 4-in-1 series…and they’re always working on new innovations. For more information visit robertkeeley.com.
Rhett and Zach end almost every episode of Dipped In Tone with a rig dip—where they discuss and rate a guitar, amp, and pedal setup submitted by a listener—but this time, they’re assembling and critiquing dream rigs of their own, on a budget.
Rhett and Zach end almost every episode of Dipped In Tone with a rig dip—where they discuss and rate a guitar, amp, and pedal setup submitted by a listener—but this time, they’re assembling and critiquing dream rigs of their own, on a budget.
They each get to brainstorm a $1000 rig followed by a $10,000 rig, using toys and prices found on Reverb. When you’ve only got 10 Benjamins to spend, what pieces of kit should you prioritize? Rhett throws most of his budget behind his guitar and amp head, with just a few bucks left for a bargain-bin cab and a couple cheap pedals, but Zach spreads his grand out fairly evenly, opting for affordable offerings from Epiphone and Vox for his base tone.
Things get spicy in the upper range. Rhett takes Zach to task over prioritizing a $1300 vintage TS-style pedal, but they both opt for high-dollar amps from the same manufacturer for their ten-grand stage setup.Who created the better rig at each price point? Which components did they fumble? And what would you do with each budget? Let us know in the comments.
