SCROLL
The difference

The world builds copies.We build originals.

Most "boutique" amps are the same handful of circuits in fresh paint — another JCM800, another Dumble, another Klon, another Tube Screamer. It's easier to ride a name that already has a following.

KAOS doesn't repackage. Every HatreD, every F!, every PornBass is an original design, developed from the first resistor up — because nothing on the market did what it needed to. That's why these amps end up in collections beside the names you already know.

One pair
of hands.

No production line. No shortcuts. Just tone, obsessed over since 2012.

Tell me the sound in your head. I'll build the circuit that makes it real.

KAOSAMP is essentially one builder who got tired of the same reissued circuits and designed a full line that didn't exist yet. Since 2012, every amp is drawn, wired, tuned and signed off by hand — no two identical unless you want them to be.

What you're really buying is intuition: the ability to take the tone you describe and translate it into electronics that deliver it. Clients keep coming back for one reason — how faithfully a KAOS carries their own playing.

Then we'll
build yours.

Different power, different voicing, your tolex, your faceplate, a full custom 2×2 — most of what makes a KAOS a KAOS is that it's built around you. If you can describe the sound, it can be built.
