The BOSS Katana KTN 50 amplifier cuts the way for your guitar in a sharp and powerful way. With 50 watts of power and a custom 12-inch speaker.

The name of the classic Japanese sword rests to perfection because the KTN 50 is a work of precision, mastery and art. The KTN 50 is for guitarists who want to get the most out of their sound and power without losing dynamics and subtlety. In addition to the traditional 3-frequency controls, you can choose from five amplifier profiles, ranging from the most traditional and organic to the most modern and aggressive tones, especially made for those who play in heavier genres.

Clean is a clear profile, and an excellent base for the range of effects available on the Katana. There is also an Acoustic profile to connect your electro acoustics, which maintains the natural sound of the guitar. The most saturated profiles are the Crunch, full of attitude and grain, Lead for anyone who wants sound definition and sustain for solos, and Brown, overwhelmed with strength for greater presence, but tuned to cut violent riffs with precision.

But with the Katana KTN 50 you can expand your range of sounds in such a way that the pedals can stay at home. In BOSS Tone Central you will find ready-to-use effects for various styles that can be downloaded to your amplifier and edited to your liking. Accessing the effects is very easy using the two memory banks available on the KTN 50, and selecting them using the front panel or a footswitch.

The effects included in the Katana KTN 50 are some of the most mythical and popular of the BOSS: the Roland DC-30 Analog Chorus-Echo, BOSS GE-10 Graphic Equalizer, and the 95E wah pedal all in one piece of equipment. The Katana can even be connected via USB to the BOSS Tone Studio to be able to use 61 customizable effects.

BOSS has always taken into account the evolution of the work environment and has designed the KTN 50 to think of the digital recording tools, providing a ¼ jack input with capture emulator to send the signal to a DAW, or to model the sound to a PA or headphones.

BOSS's Katana amplifiers offer defined and aggressive rock sounds, outlined by generations of BOSS dedication and experience. With its own circuit designs and meticulous tuning, the Katana range combines traditional construction with innovative functions to produce new generation rock amplifiers. Few amplifiers are so easy to use, with so many possibilities, and so responsive to the needs of the most demanding musicians.

Born from the development of the Waza, the Katana KTN 50 is the most effective weapon for guitarists seeking both strength and elegance with the least equipment, the best quality and enormous sonic versatility. The weapon does not make the warrior, but the Katana elevates the sound art of any guitaris
