Re: Boss Katana 100 vs 50
I tried first the Katana 100w (mainly because I wanted the option a the fx loop) and returned it, not able to get a good sound out of it. Then I read Gearpage mega-thread (
https://www.thegearpage.net/board/index.php?threads/boss-katana-amplifiers.1744135/) and figured the problem should be me not the amp. So I bought the Katana 50w because I wanted something small and lightweight as I have other amps. I learned how to create very good presets out of it. If someone cannot get a usable sound out of the Katana it's because, as any piece of gear, they don't take the time to learn how to do it.
The sound of the Katana is basically around the power section, so crank the master volume (at 0.5w/25w/50w) and set gain/channel volume to taste. The speaker in the K50 is pretty stiff, so plug an mp3 player in the aux-in and let it play loud for 24 hours. The K50 doesn't have a presence knob, so depending of the guitars or the pedals in front, you may have to connect to a computer to lower it using Boss Tone Studio or Gumtown's FxFloorBoard.
Just take into account that Katana 50w will never be on par with a boutique rig and being a 1x12" open back combo it will never sound like a 4x12" close back stack, that was not the intended design. But it can be an excellent additional amp when you don't want to take that expensive tube amp for a jam with friends. Cheap ($229), light (25lbs), good sound, responsive, built-in effects, 4 presets (which is enough in my case for a quick jam with 2-button footswitch), aux-in with an impressive 0.5w mode for late at night practice when you cannot crank the tubes.
