Last week I sold my Mustang III v2 to a bandmate and got a Katana 50; after hurting my back again a couple of months ago, the Fender was too heavy to carry to and from band practice. I like the Katana a lot--I took it to band practice for the first time last night and found I could basically just use one tone with my Tele (most playing at about half volume on the guitar, then dimed for solos). The band is a rotating cast, but yesterday was me on electric, 2 acoustics and a bassist. I'd spent some time trying to dial in some progressively louder and dirtier tones, but found that I could do everything I need with just one sound. I really like how long the amp sustains notes. Oh, and I used the octave setting on one song to play "faux" bass. For what it's worth, I stayed on the 25 watt setting all night (the drummer wasn't there), and felt that there was definitely volume to spare if I needed it. Love the light weight, for sure!
