Boss Katana-Artist MkII Guitar Combo Amplifier (100 Watts, 1x12")

A Katana amp built for pro players! The Boss Katana Artist MkII combo amplifier brings a host of Boss effects to the table along with a 12" Waza speaker.

The Katana-Artist MkII elevates the premier model in the Katana lineup with next-generation features and flexibility. Newly voiced variations for all five amp characters double your tone choices, while onboard effects categories have been expanded from three to five. Exclusive front-panel controls provide even more sound-shaping options, including a three-way Contour switch, Global EQ with three customizable curves, and a Solo boost with adjustable level. And with powerful new dual amp functionality, it's easy to link and control two Katana-Artist MkIIs for massive, ultra-wide tones.

Refined Sound for Professional Performers:

Just like its predecessor, the Katana-Artist MkII has been designed with extra detail for discerning pro players. BOSS's custom Waza speaker puts the ultimate vintage rock sound under your fingers, while the cabinet's wide baffle and semi-closed back provide focused, punchy tones with rich low end and big midrange fullness. In addition, every Katana-Artist MkII amp character has been specially voiced for optimum response with the speaker and cab.

Waza Speaker: Legendary Tone, Modern Power:

A key element to the Katana-Artist MkII's powerful sound is the 12-inch Waza speaker, developed by BOSS to deliver the wide dynamic response, smooth midrange, and rich harmonic overtones of the benchmark 25-watt British stack speaker from the 1960s. Through detailed analysis of original speakers and careful selection of the magnet, cone material, and other read more elements, the Waza speaker embodies the full mojo of this legendary speaker while boosting power capacity to 100 watts.

Expanded Amp Characters and Effects:

The Katana-Artist MkII features the same core updates introduced with the Katana MkII amps. Variations are now available for the five amp characters, providing 10 different tone options to choose from. And with five simultaneous effects categories, you have the sound-shaping power of a massive pedalboard right inside your amp. Connecting to BOSS Tone Studio lets you dive much deeper if you want-customize the sections with over 60 different effect types, change the order with four different chains, and much more.

What an excellent amp, really I’m astonished! If your debating on getting the 50 or 100 watt MKII’s just spring for the Artist, it’s worth it. I bought the 50 watt version and really liked it, I just wanted to upgrade the speaker. The only thing is with what’s out there for speaker replacement things can get pretty pricey, since the artist has the Waza speaker it seemed like a no brainer. Plus the presence knob, cab sim, and global eq.... This thing takes pedals well and the onboard delay and reverb are superb. Seriously, this thing screams!
