Line 6 Catalyst 100
line6.com
Line 6’s Catalyst series is the latest in a generation of amplifiers bridging the gap between digital modeling’s enormous possibilities and many players’ desires for old-school simplicity. These amps offer detailed, convincing amp models—but not too many of them—in a compact, vintage-style design that makes avoidance of option fatigue a priority. The very accessible prices also make the series a direct competitor to Boss’ ultra-successful Katana amps. The Catalyst is offered in three models: Catalyst 60 and Catalyst 100 (both of which have one 12" speaker), and the Catalyst 200, which has two 12" speakers. For this review I tested the Catalyst 100, which sells for a very modest $399.
Simple Complexity
The Catalyst has plenty of bells and whistles. On the surface, though, it looks a lot like a simple, conventional 2-channel amp. There are knobs for boost, gain, bass, mid, treble, presence, channel volume, effect, reverb, and master volume. There’s also a knob that lets you choose from six original amp models: clean, boutique, chime, crunch, dynamic, and hi gain. Mini buttons let you save and choose between two channel presets or engage manual mode, where what you see is what you get. Other mini buttons allow you to engage boost, tap tempo, and select effects and a tuner. On the back panel is an output power knob that lets you choose from mute, ½ watt, 50 watts, and 100 watts. There’s also a USB jack, a DI out, and an effects loop.
Six Amps in One
There’s not enough space in this review to cover all the amp models in depth. And I suspect that for many players even just a few used through the full range of their clean and dirty variations will be everything they ever need. Still, the Catalyst’s abilities and potential—especially relative to its price—will excite any potential user.
I started my own experiments with the boutique voicing at the ½-watt output setting. Predictably, there’s not a lot of output in this mode, though it’s a lot of fun as a practice amp. At the 50-watt output setting, though, I could hear and feel the amp in a more complete way. There was headroom to spare and it’s impressively dynamic and responsive to picking nuance. And it was surprisingly easy to get SRV-style bite out of otherwise clean, blues-tinged phrases—again, very impressive. The useful boost knob lets you dial in extra kick, and, thoughtfully, each amp model has a specifically tailored boost voicing. In boutique mode higher boost settings added a lot more gain to the amp model’s cleanish sound, and the saturation sounded and felt organic.
The chime model, loosely inspired by a Vox amp, is warmer and thicker than the boutique model in cleaner settings. But when I engaged the boost (with the knob at noon) and set the gain knob around 11 o’clock, the amp positively screamed—generating an aggressive and at times piercing sound that would reward a player with a commanding approach like Eric Gales or a 1960s-influenced guitarist who loves the potency of single-note lines.
The high-gain model, meanwhile, is a fire-breathing beast. With the gain at 11 o’clock, there is plenty of bottom end, and the sensation of the amp moving air becomes more apparent. Engaging the boost softened the attack slightly, which made soloing more liquid. But there wasn’t much of a difference through the range of the boost knob from noon to max. The amp model is pretty saturated to begin with.
There was headroom to spare and it’s impressively dynamic and responsive to picking nuances.
No Jumping Through Hoops Running Loops
Using the clean model, I ran my Yamaha UD Stomp delay through the effects loop. The results were dimensional and often sublime. The power-amp-in feature lets you plug in a pedalboard and play it directly into the Catalyst 100’s power amp. I used another setup, with a Mesa/Boogie V-Twin preamp pedal, directly through the Catalyst’s power amp and it sounded phenomenal. And even though the preamp is bypassed in this mode, the boost function is still active. Set at 10 o’clock, it added a nice final touch to the Mesa/Boogie preamp’s clean channel, making it sound discernibly richer. In my humble opinion, just the power amp and speaker cabinet alone are worth the $399 price.
Though Line 6’s acclaimed HX technology is embedded in the Catalyst, the company did a good job of keeping options easy to manage and navigate. There isn’t an endless buffet of effects, as you might expect. There’s a standalone reverb, and apart from that you can only use one additional effect simultaneously, unless you bring your pedalboard to the party.
In total there are 18 effects, grouped into three categories: delay, modulation, and pitch/filter—each with a corresponding LED in green, blue, or purple, respectively. If you’ve used Line 6 products before, many of these excellent effects (and the color coding) will be familiar. There’s the fabulous dynamic “ducking” delay, some modulation models based on iconic pedals like the MXR Phase 90 and others, and some classic Line 6 pitch/filter effects like growler synth and synth strings. If you do want to use more effects simultaneously, the effects loop is an excellent way to patch in external effects.
The USB hookup, by the way, enables connection to a computer so you can use Line 6’s editing software, which allows you to dive deep into tone editing or just fine tune a few things. I imagine that, in reality, most users will just figure out how to get a couple of core sounds directly from the amp, save them, and just go with that. But it’s always great to have options, and if you’re someone that actually maximizes the capabilities of modelers and editors, you’ll have a field day with the app.
The Verdict
For any guitarist looking for an all-in-one, plug-and-play setup for practice sessions, live shows, and recording (you can record directly using both USB and the built-in DI with cab simulation), the Catalyst, at $399, is pretty tough to beat. It’s got more features than many players will need, but what will count for most of the target audience is how much you can accomplish without diving too deep. And though the price might suggest otherwise, Catalyst isn’t just for beginners or intermediate players. Any professional guitarist that’s tired of dealing with tube related maintenance and expenses will be happy with many of the sounds here.

AEROSMITH guitarist and songwriter JOE PERRY is set to return to the road for a series of August performances with THE JOE PERRY PROJECT. The 8-date run kicks off August 13 in Tampa, FL and wraps August 23 in Port Chester, New York, with an August 19 performance in PERRY’s Boston hometown (see the itinerary below). For the North American trek—which marks the first solo shows for PERRY this year—the legendary guitarist will be joined by his Aerosmith bandmates Brad Whitford (guitar) and Buck Johnson (keys), along with The Black Crowes’ Chris Robinson (vocals), and Stone Temple Pilots’ Robert DeLeo (bass), and Eric Kretz (drums).
“Well…it’s time to let the music do the talkin again,” PERRY says. “I’m really excited about the JPP line up this year!!!! Most of these guys played with me at The Roxy in L.A. at the debut event for my latest solo album [Sweetzerland Manifesto] in January 2018. They’re all busy as hell but thankfully they’re able to carve out some time for this run. And I’m not only lucky enough to have Brad Whitford onstage with me but Chris Robinson of The Black Crowes! [who sang ‘Fortunate One’ on Sweetzerland Manifesto MKII], Robert DeLeo and Eric Kretz from STP!!! and Buck Johnson who plays keys and sings with Aerosmith, the Hollywood Vampires, and is also a solo artist in his own right.”
For the shows, the Rock and Roll Hall of Fame inductee says “the set list is gonna include my fav JPP cuts, STP, Black Crowes, and with Brad we’ll be hitting the Aero hits and some deep cuts and then ya never know!!!! Gonna be a BLAST, and if you’ve ever been to one of my shows you know the words GARAGE BAND on STEROIDS come to mind! See you there!!!!”

Seasonal changes are tough on your acoustic. Here’s how you can take better care of your prized instrument.
As you read this, spring is in bloom in most of the US, or maybe it has been for some time. I’m timing this column specifically to ask acoustic guitarists, in this season of increasing humidity and comfortable conditions, to prepare for what’s coming. It’s never too soon, and time flies. Before you know it, we’ll be back to the maintenance phase and you might be blowing up the phones of your local guitar shops, luthiers, and techs. I’m here to encourage a decidedly old-school approach to preventative guitar maintenance, and yes, it starts now.
Why, you ask? Well, as the lead luthier at Acoustic Music Works, I can tell you that in my nearly 15 years in this position, this was the worst winter ever for preventable repairs on acoustic guitars. Fret sprout, bridge lifts, top sink, soundboard cracks, back cracks, loose binding, general malaise… These hit us very hard in the winter that spanned 2024 and 2025. Am I complaining? On the one hand, no. This is part of how we make our money. On the other hand, yes! Repair schedules related to dryness and humidity issues can stretch into weeks and even months, and nobody wants to be without their favorite instruments for that amount of time. With a little thoughtfulness, however, you might get through next winter (and every one thereafter) without hefty repair bills or time apart from your musical companion.
Our preparation is going to start with an unlikely but very important guitar accessory: the humble notebook. Plain, lined, grid, day planner… it doesn’t matter. We all need to actively participate in our instrument maintenance, and in my experience, fancy apps that track humidity via Bluetooth breed a kind of laziness, a feeling of safety that might prevent us from actually physically looking in on conditions. Better we keep an analog, well, log, so that we know where things stand, and I suggest checking in daily.
“This was the worst winter ever for preventable repairs on acoustic guitars.”
Track your relative humidity, both in the case and in the room where your instruments mostly reside, but also take notes on your action height, top deflection (StewMac has some great tips for measuring this) and anything related to playability that you believe you can observe empirically.
Dryness is the root cause of most guitar issues that manifest in the fall and winter months. Symptoms of dryness include sharp fret ends, falling action and dead frets, sunken top around the sound hole, and cracks and bridge lifts. With your trusty notebook, you’ll get a feel for the sensitivity level of your instrument, and that knowledge is power!
A few other basic implements will not only assist you in your observations, but may also satisfy your need to buy guitar-related things (at least for a minute). Getting quick and comfortable with a fret rocker is a great skill to have, and is invaluable in diagnosing buzzes due to high frets or frets that have come unseated due to dryness. A well-calibrated relief gauge might seem luxurious, but it can prevent you from making unnecessary or extreme truss rod adjustments. A string action gauge, or even a simple machinist’s rule or set of feeler gauges, will help you keep track of your action. Get a three-pack of hygrometers so you can average their readings, rather than depending on one.
Lest we forget: A guitar can not only be too dry, it can also be too wet. By beginning your maintenance diligence in the spring/summer, you’ll also be able to tell if your instrument is the victim of a too-humid environment. The signs of over-humidification are subtle: Your action may rise from a puffed-up top, and in extreme cases, glue joints could begin to fail. In my experience, an over-humidified guitar will suffer from dulled tone, almost like a sock in the sound hole. If you’re sensing a lack of clarity in your guitar all of a sudden, start with new strings. If it persists, it might be due to over-humidification, and you may want to introduce a desiccant to the case for a time. The more lightly built your guitar is, the more sensitive it will be to seasonal changes.
By getting into these habits early, you’ll be empowered by knowing your instrument more intimately. You’ll understand when and why changes in tone and playability might have occurred, and you’ll hopefully save on repair bills year-round. Feel free to reach out with any questions. Who knows? I might just send you a notebook with an AMW sticker on the cover!
