I was seconds away from buying a Boss Mini Katana before I seen this. I played the two side by side and this one was louder. Plus this amplifier has more tones (10 on the Vox vs. 3 on the Mini Katana). The final decision was the AC adapter was included where the Boss Mini Katana didn't include one and it cost more than the Vox. The tones are pretty cool and even plugged in my acoustic electric guitar to it and it sounded good. I just wanted a smaller amp to use so I don't offend my neighbors at night. The salesman at Sam Ash was very nice and patient with me as I tested both amps out, asking questions and any other needs I had.
