I purchased this beauty to go with my amazing Krakenheart Uni-Vibe, which is superb! There are a wide range of sounds and colours in this flanger, from subtle chorus to swirling jet plane. I love it! 🤩.

The Royalbreaker is absolutely fantastic.
The build quality is outstanding, from the pedal itself to the small instruction booklet. The screen printing and the embossed chassis details are a classy touch, and the overall quality is excellent. The sound is incredible — it can go from a light and soft overdrive all the way to fuzz-like textures, and it always feels musical and inspiring. The presets suggested in the manual are also spot on.
Customer care and professionalism are at the highest level — without a doubt the best pedal and buying experience I’ve ever had!!
Excellent job, Krozz Devices!!🔥

love my flanger

Great Vibe, nice adjustment choices to tweak the throb. Lovely and creamy! Really good company to deal with too. So helpful with shipping enquiry. Highly recommend.

If you are wanting a good sounding flanger, this is the one for you. Nothing 'too' fancy here like a step sequencer or other weird waveforms, but it does have positive/negative feedback and an oxidized knob to tone the frequencies. I would really like to see them add a through zero option to this pedal, but i know that adds a lot more to the equation.

I've been impressed with my other Krozz Devices pedals and wanted one of these Albino Rhinos never finding one on the used market. I snatched up a new one when they were reissued and am blown away. Thick, heavy, raw, smooth, loud, jangly...this pedal can do all of this with massive tweaking options. Highly textured distortion and drive await you. Happy rocking from PA, USA.

Exactly what I've been searching for. Amazing analogue flanging in the family of EH with greater flexibility and "dialability." Doesn't do that horrible analogue modulation pedal thing where it loads down the output and lowers the volume when engaged and the true bypass is perfect with no leaking of the flanged signal after switching the effect out of circuit.

Great pedal with a versatile range. Will definitely be a keeper!

I already had the Krakenheart from Krozz Devices that I really liked. I follow on social media LetsPlayAllGuitar, who makes amazing covers and reviews of great pedals. Saw this pedal for the first time on his channel, and it sounded just soooo good that I started to look after other reviews.
After all those videos, I ordered one by Palf.fr (that I really recommend if you look to order pedals in Europe!!!! Great service! Merci a vous si vous voyez le message du coup 😉).
When I received it and opened that box, just the looks of this pedal are hot! Well built, a nice and solid case! The design is just super but I already saw that on the internet. But still in real, it's just amazing! Then, I putted this beauty on my new pedalboard, where I left a place open for this Royalbreaker. I've set the knobs on a setting that I saw in a video of LetsPlayAllGuitar when he plays a Foo Fighter song. Amp on, pedal on, 1 strum on my guitar and 🔥🔥🔥 DAMN!!!! What a sound. There's a crown on this pedal, and it really deserves it in my opinion! It growls, the sound... well difficult to describe it, but if you're hesitating, go watch some YouTube videos, and if that's the sound you're looking after, order one! You won't regret it 😎
It's also nice how you can have a kind of different sound by playing with the voltage (my preference is 9v to have more that 🐀 sound from it, but in 18v it sounds killer too!).
Thanks Krozz Devices to made such a good pedal, looks are hot, sound is even more incredible. Can't wait what you'll bring out in the future !
And yeah, thanks @LetsPlayAllGuitar (insta or letsplayall youtube) for the super lessons and videos that you make !
And merci to Palf.fr for the service when you order a pedal from their site!
And sorry for the long texts, but it's over, I'm leaving to have some fun on

🔥🔥🔥 THE ROYALBREAKER !!!!!🔥🔥🔥

This pedal is very well build. Nice graphic. But what set it apart from the myriad of other overdrive/distortion pedal is the sound. Or should I say soundS. The « Rising » knob with the voice switch can cover a lot of ground. Works well with a clean amp by itself or combine with other pedals. I am impress.

This is an amazing vibe. Me and Krozz had a back and forth conversation about it because I couldn't exactly get the sound I was looking for, because compared to another vibe I have, this definitely has a lot more throb and even with the extra controls it will still be more of a square wave when you crank that depth knob. So I would keep that in mind. But nonetheless I think the addition of a ramper on a univibe is very unique, and this pedal has a lot of headroom, and is great for bass given the internal trim pot. I recommend actually dialing the bass back on the pot so your amp doesn't get too woofy. I still deifnitely think krozz should come out with a v3 that has a symmetry control that lets you sweep from a sine wave to a square wave and is completely independent from the depth control, so that way the throb can be dialed way back when you just want light/smooth modulation, but it still is a really fantastic pedal.

Pro's: Clean, Natural tambres that can slice thru a mix. No strident here. Controls are intuitive and useable sounds come with ease.

Cons: maybe, some more tweakability maybe adding an option to put the effect a bit back more in the mix.

I have used more expensive Flangers but the airborne to me may be the
Best Flanger for price point and easily challenges those that are hundreds more.

As a happy Airborn Flanger owner it was easy to pull the trigger on the Krakenheart. I guessed a preset I would like it and it was almost spot on with how I set my vibes pedals. I've owned many vibes and this tops em all in my opinion. Great work Krozz team!

… this one might still be the one!
To be honest, I do like the flanging effect, but only in very few specific forms. Tried some pedals, certainly the classics, liked them more or less, but none was really perfect for me.
This one is different ! Totally love it, easy to dial in the settings I want! And since it’s super versatile, it will probably satisfy lots of people, no matter, if your totally into Flanging anyways or if you are a kind of „flanger-snob“, like me.
This one does the trick!

Full disclosure… this is my 8th univibe I currently own. I have a real problem.

Great tweak ability, excellent tone/eq balance through the range of knobs, and just generally sounds great.

My only beef is that in chorus/dry mode (traditional univibe Hendrix-esque mode) the waveform is a little too balanced for my liking. It doesn’t have that super lopsided throb vibe of the original univibe circuit; it’s closer to a sine wave. This probably won’t translate in text… but think wah-wah-wah-wah vs old school wuh-wah, wuh-wah, wuh-wah. Still a very usable and toneful swirl, just a different character and I find myself missing the older style tone.

BUT the same symmetry that you hear in chorus mode, is present in vibe/wet mode. And it’s phenomenal. This pedal in vibe mode, with speed set to 25% and depth set to 50% has been an absolute revelation to my clean/slightly dirty tone. I put it in the effects loop and literally have left it on for the last week. It yields a subtle warble-shimmer that no one hears until I turn it off. A rare piece of gear that inspires you to create new music and play things you wouldn’t have otherwise.

So, overall, I don’t use this pedal how I expected to, but it’s been worth every penny and then some.
