KARTAKOU COLOSSUS | HANDMADE TUBE PREAMP

Colossus is designed to give your guitar tone the mass of a boulder and the permanence of a monolith. Six tube cascades work in sequence to turn your hand into a hammer that shatters bedrock with every palm-mute.

Both Lead and Clean channels have independent EQ. The added Sweep control allows you to sculpt the Lead from heavy and thick to tight and cutting.

A dedicated IR Cabsim Output means you don't need a power amp or cabinet to get the full stack tone — just load your favorite IRs and plug Colossus straight into a line-in or DAW.
