However, you do need to adjust settings between those scenarios and this is where the Katana falls flat a bit. You only get to save a few presets. And, when you are in a specific preset, you can't know where exactly your EQ pots are dialed in, so rotating one of them makes your settings jump to an extremely different location. I move to this amp after my starter amp, a little (and also great for what it is) NUX Mighty Air, and I'm very happy with the much it provides for my specific use cases. On a sidenote, the head version of the Katana MkII also features a MIDI input.

Better yet; unlike regular tube amps, the Katana MkII 100-212 combo amp features Power Control so you get incredible sound at any output level.I find the Pros of this amp are the four chanel selections that you can save for your own personal tones and sounds. This feature allows you to play TWO Katana MKII amps side-by-side, connected by a single cable, and gives you access to an array of stereo-compatible effects - such as chorus, delay, reverb, and more!
