This is not my only amp but it fills a nice niche. Overall sound and feel are very much like a tube amp and I have 2 tube amps sitting beside me. However, if volume is a concern the Katana will actually turn down to a level that makes tube amps sound iffy. The volume at 50 watts is more than adequate. Coupled with the software any sound is possible using the 50+ built in effects. I tried some Boss stomp boxes with it and it's difficult to tell the difference between the amp built in effects. 4 presets is great and the footswitch to toggle between them is only $60 so it's very giggable. If you want an amp that yu can tweak to eternity this is it. I love playing around with it and the overall EQ allows you to dial out any boxiness from the relatively small box. The USB out does a good job for recording and even this is tweakable, if such a word exists. That is this amp, tweakable and it sounds way better than the $200 price tag would have you believe.
