The Miku was introduced about 10 years ago and is based on the vocal stylings of Hatsune Miku, a virtual pop icon. But it does much more than artificial vowels and high-pitched words.
It’s tempting to think of this pedal as a joke. Don’t.
It all started a few years ago through a trade with a friend. I just wanted to help him out—he really wanted to get a fuzz pedal but didn’t have enough cash, so he offered up the Korg Miku. I had no idea then, but it turned out to be the best trade I’ve ever made.
Here’s the truth: The Korg Miku is not your typical guitar pedal. It won’t boost your mids, sculpt your gain, or serve up that warm, buttery overdrive you’ve always worshipped. Nope. This little box does something entirely different: It sings! Yes, sings in a Japanese kawaii accent that’s based on the signature voice of virtual pop icon Hatsune Miku.
At first glance, it’s tempting to dismiss this pedal as just a gimmick—a joke, a collector’s oddity, the kind of thing you buy for fun and then forget next to your Hello Kitty Strat. But here’s the twist: Some take it seriously and I’m one of those people.
I play in a punk band called Cakrux, and lately I’ve been working with a member of a Japanese idol-style girl group—yeah, it’s exactly the kind of wild mashup you’d imagine. Somewhere in the middle of that chaos, the Miku found its way into my setup, and weirdly enough, it stuck. It’s quirky, beautiful, occasionally maddening, and somehow … just right. After plenty of time spent in rehearsals, studio takes, and more sonic experiments than I care to admit, I’ve come to appreciate this pedal in unexpected ways. So here are a few things you probably didn’t know about this delightfully strange little box.
It’s Not Organic—and That’s OK
Most guitar pedals are chasing something real. Wah pedals mimic the human voice—or even a trumpet. Tube Screamers? They’re built to recreate the warm push of an overdriven tube amp. Cab sims aim to replicate the tone of real-world speaker setups. But the Miku? It breaks the mold. Instead of emulating reality, it channels the voice of a fictional pop icon. Hatsune Miku isn’t a person—she’s a vocaloid, a fully digital creation made of samples and synthesis. The Miku doesn’t try to sound organic, it tries to sound like her. In that sense, it might be the only pedal trying to reproduce something that never existed in the physical world. And honestly, there’s something oddly poetic about that.
A World-Class Buffer
Here’s a fun fact: I once saw a big-name Indonesian session guitarist—you know, the kind who plays in sold-out arenas—with a Miku pedal on his board. I was like, “No way this guy’s busting out vocaloid lines mid-solo.” Plot twist: He only uses it for the buffer. Yep, the man swears by it and says it’s the best-sounding buffer he’s ever plugged into. I laughed … until I tried it. And honestly? He’s not wrong. Even if you never hear Miku sing a note, this pedal still deserves a spot on your board. Just for the tone mojo alone. Wild, right?
“The Miku is one of those pedals that really shouldn’t work for your music, but somehow, it just does.”
Impossible to Tame
Most pedals are built to make your life easier. The Miku? Not so much. This thing demands patience—and maybe a little spiritual surrender. First off, the tracking can be finicky, especially if you’re using low-output pickups. Latency becomes really noticeable and your picking dynamics suddenly matter a lot more. Then there’s the golden rule I learned the hard way. Never—ever—put anything before the Miku. No fuzz, no wah, no compressor, not even a buffer! It gets confused instantly and says “What is going on here?” And don’t even think about punching in while recording. The vocal results are so unpredictable, you’ll never get the same sound twice. Mess up halfway? You’re starting from scratch. Same setup, same take, same chaotic energy. It’s like trying to recreate a fever dream. Good luck with that.
Full Range = Full Power
Sure, it’s made for guitar, but the Miku really comes to life when you run it through a keyboard amp, bass cab, or even a full-range speaker. Why? Because her voice covers way more frequency range than a regular guitar speaker can handle. Plug it into a PA system or a bass rig, and everything sounds clearer, richer, way more expressive. It’s like letting Hatsune Miku out of her cage.
The Miku is one of those pedals that really shouldn't work for your music, but somehow, it just does. Is it the best pedal out there? Nah. Is it practical? Not by a long shot. But every time I plug it in, I can’t help but smile. It’s unpredictable, a little wild, and it feels like you’re jamming in the middle of a bizarre Isekai anime scene. And honestly, that’s what makes it fun.
This thing used to go for less than $100. Now? It’s fetching many times that. Is it worth the price? That’s up to you. But for me, the Korg Miku isn’t just another pedal—it’s a strange, delightful journey I’m glad I didn’t skip. No regrets here.
