Kartakou Colossus Tube Preamp

When the time comes, you feel the urge to let your guitar voice beyond the confines of your bedroom walls. You are looking for the perfect tone to share your message with the world and conquer new horizons, whether it's live performances or recordings.

Colossus was engineered to handle the most aggressive and adamant messages. Six tube cascades work in sequence to filter out any unnecessary junk while simultaneously magnifying every important detail.

An indecisive whisper will transform into a powerful scream, while a confident speech will turn into a bloody roar, and a palm mute will sound like the impact of a multi-ton press. Colossus will assuredly take its position in the mix and keep steady till you end your line.

Independent EQ for each channel with an additional Sweep knob for the Lead allows you to precisely tune your tone for any power amplifier and a cabinet.

When the line-in is only an option, using an IR-based cabsim will give you a feel of playing through a real guitar stack.

Colossus Identities

Entire Tube Architecture

We believe tubes hold their unique place in incalculable setup variations. With six triode sequence Colossus delivers all of the achievable gain on this Planet right to your amp.

Authentic Tubes Voltage

Don't be misled with a low-voltage Colossus power adapter. Internal voltage converter generates more than three hundred volts to reveal all tube potential.

Lead / Clean Channels

Lead channel delivers a gut-punching solid wall of gain. However, even the most aggressive guys need a recovery. Turn on Clean channel for this purpose. EQ is independent for each channel.

IR Cabsim Simulation

Colossus has an outstanding CabSim based on Impulse Response technology. Load up to four IRs into internal Flash memory to play with the feel of a real cabinet.

FX Loop

Colossus has a switchable FX loop and provides you the possibility to engage or disengage all of the devices connected to the FX Loop with one click.

Hand Built

We believe machines are good. However human beings are unbeatable. Handcrafting adds a certain feel to every assembled device. All of our creations have lots of human work.
