I’ve always been the kind of player who avoided going direct to the mixing board or FOH whenever I could. But lately, the stage reality has forced me to make peace with the direct setup. Seeing a real guitar amp onstage now feels like stumbling across a rare oasis. I often end up borrowing a friend’s Boss IR-200 just to blend in with this new stage normal. Not because it’s the ultimate box, but because it’s what I can get my hands on. If all I could find was a cheap Sonicake IR loader, I’d still take it—anything to save the gig.Then my five-year-old son started learning guitar and asked for a stompbox. I first thought of getting him a multi-fx—cheap, practical, a good way to explore sounds. But he had one condition: everything had to be blue. Finding a blue multi-fx was harder than I expected—Boss ME units are rare, the Zoom MS series wasn’t “blue enough”—so I got him a DigiTech Screamin’ Blues. Affordable, with a cab-sim out that might come in handy for me, too. I tried it, and to my surprise, I loved its raw, simple tone.Part of me wanted to get him something digital signal processing (DSP)-based for consistency and versatility, but I found myself overwhelmed by the sheer number of options. It felt like buying a mystery box. And that made me realize—this personal dilemma is just a microcosm of a bigger trend. Digital technology is reshaping not only how we play and hear but also how we define guitar tone.We are living in the golden age of digital emulation. Amps, pedals, mixers, even speakers—nearly everything that was once purely analog has been distilled into algorithms. As with every revolution, mass adoption comes with pushback. The “amp sims vs. real amps” question still rages on, a never-ending debate.But strip away the nostalgia of glowing tubes and “the warmth of the amp,” and one fact stands out: DSP leaps forward year after year. We’re now in the age of AI and machine learning.Flashback to 2011 when the Kemper Profiler dropped like a bomb on the guitar universe, offering the first device that could capture the “DNA” of an amp and recreate it so convincingly that most players couldn’t tell the difference. With IR loading built in, players could now carry studio-grade tone straight to the stage.Of course, such tech came at a price, and not everyone could afford a Kemper. Slowly, alternatives emerged: IR loader pedals like the Two Notes Torpedo Cab, multi-fx units like the Line 6 Helix and Boss GT-1000, and even software plugins that approached hardware-level realism for a fraction of the cost.“Are we heading toward an oversaturated market, maybe even a bubble burst?”This perfectly illustrates Moore’s Law: as technology advances, production costs drop. What once required a computer-killing amount of processing power can now fit inside a compact pedal. Today, a stompbox can run hundreds of high-res IRs with sub-2 ms latency. DSP devaluation has made pro-level tone available to everyone: flagship rigs like the Neural DSP Quad Cortex, Fractal Axe-Fx, and Fender Tone Master Pro; mid-tier units like the Line 6 Helix, Boss GX-100, Boss IR-200, Headrush MX5, and IK TONEX; and budget-friendly gear from Mooer, NUX, Valeton, Joyo—even open-source IR loaders. What used to be reserved for high-end studios, pro musicians, or crazy rich hobbyists is now in the hands of bedroom players with nothing more than a laptop or smartphone.Impulse responses became the cornerstone of cab simulation, allowing us to “photograph” the sonic fingerprint of a cab, mic, and room, then swap between them at will—Marshall 4x12 to Fender 2x12, studio ribbon mic to SM57, even legendary room captures—all just a file change away.If profiling is like a still photograph, capture is like a moving picture. Capture technology, as seen in the Quad Cortex and TONEX, uses machine learning to model non-linear behaviors like sag, clipping, and dynamic response, producing results almost indistinguishable from the real gear. Many touring pros are now comfortable leaving their amps at home and going direct with digital rigs and IEMs—something that would’ve been unthinkable 15 years ago.And yet, despite how good this tech has become, purists still argue that amps and cabs have a soul that can’t be cloned. They talk about speaker interaction, power-amp sag, and the physical push of air. The other camp counters that consistency, portability, and reliability outweigh the romance of hauling heavy tube amps.This paradox fascinates me. Sometimes I wonder if all these breakthroughs are just ways to solve logistics and efficiency problems. Why do so many of our algorithms seem stuck in a loop of chasing “perfect emulation?” Because in the end, emulation is still just imitation. I find myself longing for innovation that pushes us forward—toward creativity that truly inspires. I think back to the first time I tried the EHX Freeze and Superego pedals —not amp simulators at all, but they gave me a true “eureka” moment.And so I keep coming back to a phrase that feels both inevitable and frightening: saturation point. Every year brings dozens of new products, but the differences between them get smaller and smaller. Are we heading toward an oversaturated market, maybe even a bubble burst? Perhaps now is the perfect moment for the industry to step away from the arms race of “better emulation” and offer something beyond—an oasis of new ideas that encourage players to create, explore, and be inspired to make music.
