Strap in, mates! True Cuckoo takes the Phase8 from polite to full-blown unruly with wild mods, oddball objects, and a dash of Nordic mischief. If you reckon you’ve heard it all, wait till you see magnets and 3D-printed bits turn this synth into a raving beast. Whether you’re into sonic experiments or just love chaos in your rigs, this one’s a ripper from the synth world’s most creative mad scientist.

True Cuckoo Gets Unruly: Phase8 Mods That’ll Shock Your Sound System
From Tidy to Unruly: The Phase8 Gets a Rethink
Right from the jump, True Cuckoo is on a mission: take the Phase8, a synth that starts off prim and proper, and unleash its inner larrikin. He’s not just fiddling with factory settings—he’s poking, prodding, and giving the thing a fair dinkum workout. It’s the classic Cuckoo move: start normal, then veer off into the unknown like a kangaroo breaking free from the zoo.
You get a taste of Cuckoo’s exploratory spirit as he runs through the basics—velocity, modulation, even the built-in mics—before quickly ditching the manual and going full hands-on. When the usual tweaks hit a wall, he starts touching and tapping the Phase8 itself, pushing past polite sounds into something more chaotic. The message? If you want to get wild, you’ve got to get your hands dirty and your mind open. No point treating this box like fragile porcelain—give it a nudge, see what breaks, and enjoy the surprises.
Odd Objects and 3D-Printed Mayhem
Bored with fingers, Cuckoo raids the odd bits drawer—brushes, crystals, even a nut—turning the Phase8 into a test bench for sound oddities. Gentle touches yield delicate tones, but go in too hard and you’ll cop a bass-heavy thud. It’s like finding the sweet spot on a cricket bat; finesse over brute force.
Not content with random objects, Cuckoo dives into 3D-printed accessories. Cups, weights, and weird little shapes slide onto the resonators, each one altering pitch, muting, and sometimes summoning what he calls the ‘alien’—a mysterious, vocal-like sound that pops up when things get just close enough to the magic electromagnetic field. The upshot? Every object, no matter how light or odd, leaves its mark on the sound, and the Phase8 becomes a playground for DIY sonic weirdness.

"Here we go. We can hear two things happen. The pitch went down and also it got muted a little bit."

Magnets and Resonator Madness

Now we’re cooking with gas—or more like playing with fire. Enter magnets. Cuckoo’s experiments with off-centred and twistable magnets on the resonators lead to rich, bottom-heavy tones and unpredictable behaviour. It’s the kind of sonic chaos that would make any outback thunderstorm jealous. The more magnets, the more the Phase8 morphs, sometimes even magnetising the resonators themselves for unexpected long-term effects.
He doesn’t stop at just plonking magnets on; there are springs, counterweights, and even polarity tricks thrown in for good measure. The result? An endless field of accidental discoveries, where the tiniest move can flip the sound from subtle to savage. You haven’t heard deep, gnarly bass until you’ve seen what happens when Václav’s heavy-handed magnet ideas collide with Cuckoo’s featherweight approach. And if you want to see a synth behave like it’s possessed, this section’s a must-watch.
Cuckoo x Václav: Pushing the Envelope
Just when you reckon things can’t get any wilder, Cuckoo teams up with Václav for a proper experimental jam. Václav brings in heavier magnets, new cup designs, and pitch-bending gadgets that not only stretch the sounds but nearly crack the 3D-printed parts. It’s like a BBQ where someone suggests using the Esky as a drum—risky, but with some brilliant results.
Together, they dream up hovering cups, spring contraptions, and tactile pitch benders that could easily become real-deal accessories if manufactured with tougher stuff. The vibe is pure mad scientist: nothing’s too weird to try, and every failed experiment is just a stepping stone to the next sonic breakthrough. If you want the full effect, you’ll have to check out the video—some of these sound transformations have to be heard to be believed.
Invitation to Go Bonkers
Cuckoo wraps up with a classic call to arms: don’t just watch—get your mitts on the gear and have a crack yourself. He’s sharing his 3D files, but the real point is to inspire viewers to tinker, break, and invent their own tricks. Whether it’s magnets, nuts, or a backyard Bunnings hack, the Phase8’s unruly side is only a mod away. Go bonkers, mates—there’s no wrong way to play.

"shameless self-promotion for your own experiments is encouraged at this point so thank you all for watching this and hope you have a wonderful time exploring this physical kind of they call it acoustic synthesis but physical synthesis physical electromagnetic synthesis whatever you call it go bonkers peace out everyone see you soon"
