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 orpopular.
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, Kentucky, 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 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.

...There's a lot more to it than whether Billy Gibbons or SRV was "right."
Greetings, tone hounds! I'd like to discuss two terrific YouTube videos Rick Beato and Rhett Shull recently made regarding string gauges. In Rick's video, a group of players recorded themselves playing the same Les Paul and Marshall JCM2000 setup with the only variable being four different gauged sets: .011, .010, .009, and .008. Both videos reveal the differences in tone between different gauges, and I'd like to expand on this by adding a few observations I've discovered over the years.
Everything affects everything.
In Rick's video, he mentions a discussion he had with Dave Friedman of Friedman Amps. Dave said because lighter strings produce less bass, they help tighten up the tone—and this was one of the catalysts for Rick deciding to make a video demonstrating the phenomenon.
Dave Friedman is an old friend, and we've had countless discussions about tone. He has a great saying: "Everything affects everything." In other words, each link in your signal chain impacts the overall tone: cables, pickups, amps, woods, pedals, and, of course, strings.
Each link in your signal chain impacts the overall tone: cables, pickups, amps, woods, pedals, and, of course, strings.
In Rick's video test, they went for a classic, raunchy rock 'n' roll tone with the Les Paul/Marshall setup. Had they used, say, a Stratocaster with single-coils, or even a P-90-equipped Les Paul, the results would have varied. If you prefer the tone of .009s in the video, it's possible you may have preferred .010s had they used a Strat. It's all a recipe.
Expanding on this thinking a bit, what if they'd used a 4x10 Bassman for a bluesy overdrive? The results would also vary. A hotter alnico-5 pickup would also change the tone, and if you were to use a ceramic magnet humbucker, the bass, mids, and treble would completely change! Remember to consider these things when contemplating a different string gauge.
You’re Probably Using The WRONG Guitar Strings
Let's talk SRV.
In my estimation (and Rick mentions this too), it was Stevie Ray Vaughan who inspired many guitarists to use heavier strings. But Stevie played a single-coil-equipped Strat, mainly through Fender amps. He didn't use much preamp gain because he cranked these relatively low-gain amps until they broke up naturally. His tone formula consisted of a heavy right hand and heavy strings, combined with relatively low-output single-coils into a Tube Screamer that would add mids and cut bass. The amps he used are known for their scooped mids, so you see where I'm going with this? It's all part of the formula.
My takeaway analysis:
If you're after a fat, bluesy, loud, low-gain tone, the SRV formula—heavy strings, single-coils, a Tube Screamer, and a relatively clean, cooking, low-gain amp with scooped mids—works great. On the other hand, for a Marshall-style, midrange-heavy, tight-crunch tone, lighter strings with humbuckers and a gain-y amp—without too much bass in the preamp—will get you there.
Playability, bending, vibrato.
One last thing to consider: String gauge can have a huge effect on your bending and vibrato. Heavy strings can actually make players who have a tendency towards a "nervous" vibrato and over-bending sound more controlled. Rhett Shull commented that .008s made him feel a little more tentative on the guitar. I'm sure he could get used to them over time, but his preference for overall tone and feel were .009s. That's something to consider when switching gauges.
I Was DEFINITELY Using The Wrong Guitar Strings
Thanks to Rick and Rhett for producing useful YouTube content like this. I encourage all guitarists to follow their example of learning through experimentation. Don't just assume—discover what works for you. Until next month, I wish you great tone!
