KARTAKOU BEASTBOX | HANDMADE TUBE PREAMP

Beastbox is a two-tube preamp that speaks in many voices: from rich, lightly compressed cleans to a biting crunch to a lead that holds its ground. A fully analog tone path, precise EQ, and gain that responds to your touch — this is what lets Beastbox stand strong both in the mix and on stage. Both 12AX7 tubes are fed high voltage, unlocking the full dynamic potential with nothing left untapped.

With MIDI control, external footswitch input, and a built-in USB IR loader for cabs and amps, Beastbox integrates into any guitar rig. You can set dedicated IRs for Clean, Crunch, and Lead channels so each one sounds exactly as you want.

Trails mode in the FX loop lets your delay and reverb fade out naturally. When playing loud isn't an option, the Headphone section with AUX input and balance control lets you practice along to backing tracks.

Beastbox is small enough to fit any pedalboard at only 145×120×55 mm, so everything stays compact.
