Enjoying the innovative features of digital guitar amplifiers comes with a tradeoff, they simply do not resemble the sound of the old school tube amplifiers which, lets face it, we guitar players love. But the world moves forward and the innovative R&D minds at BOSS found a way to enjoy both worlds. They called it the Katana series. The Katana-Artist is the flagship of this series. With 100 watts, custom made WAZA 12 inch speaker, innovative Tube Logic design circuit and over 50 on board BOSS effects the Katana-Artist is a great sounding, multi purpose amplifier. Three features we found extremely helpful are the different amplifier characters, tone setting memory feature and the power control switch. With the amp character feature you can choose between five amp characters, its like having five amplifiers in one. When you get to a sound you like, instead of trying to memorise it use the tone setting memories for storing it, you have eight slots. Lastly in case needed, use the power control switch to drop the amp's wattage and gain a more cranked tone.
