HatreD Series
The amp KAOS is known for. All-tube modern metal with no compromises — from the full 100-watt head to the pocket-sized Sludge, and everything a custom 2×2 can be.
One circuit philosophy. No compromises.
The HatreD is an original high-gain design — not a hot-rodded copy of anyone else's amp. Tight, saturated and brutally responsive, it's the build KAOS is best known for, and the one that put these amps into collections beside the world's famous names.
