    • Pretty good amp
I replaced a Peavey Classic 30 tube Amp with this. Mainly because it was too heavy to haul around anymore. Turns out this katana is festooned with so tone and effects options I'll probably never discover them all. 100 watts is powerful enough for my purposes. Sounds great, lighter than the boat anchor that is the Peavey, with a lot of options. You can even hook it up to your computer and download more tones and store them into the Amp. I haven't done that yet. Update: after about three weeks I still haven't found "my sound. " It's not the amp's fault though Maybe I need less gain and more reverb and delay. I play in an open mic scenario each week. Most of the guys in the house band have this Amp. Clearly they knew something I didn't until I got this Amp. I just learned that you can boost the Amp's power from 1 watt, 50%, to 100% 100-watt output. I was playing at low power at the jam sessions and didn't know it. Couldn't figure out why it wasn't getting loud enough. Now I know ... show more

    • Great amp with great tone!
Great amp! Most importantly, is the sound quality. It has a nice warm tone...almost as good as an all-tube amp...very close. I'm using this for Pedal Steel Guitar & I get a great tone from it....& plenty of power. I'll occasionally use headphones (it has a headphone jack, audio in, etc.)...& the sound quality is also great with headphones. I try not to use headphones too much, as I get hearing fatigue if using too long...& I like it loud. It has a ton of great effects in the panel...& also on the 8 channels. The Boss Tone Studio is great, but can be complex & stressful at times...especially if you're not computer savvy. Yet, once you set up an effect for a channel using the Boss Tone Studio...it's really nice. I also have the Boss GA-FC EX foot controller & it's great to have. It, is also complex at first...& takes some time getting to know exactly how to use it. If you buy the controller pedal, & need advice...there's a great group on Facebook for that...as well as videos on YouTube. There's also groups for Katana amps as well. In closing, I'm very happy with the amp....especially it's warm, silky tone. Not harsh at all....I can't stand a harsh tone! I also use effects pedals...& have a pedal board....& I always will. I appreciate the simplicity of effects pedals vs. the built in effects to be quite honest. All in all...I love my Boss Katana 100 Gen 3, & definitely recommend buying it. Great amp, that is in my price range! Oh...I definitely recommend spending a few more dollars & buying the 100 watt Katana...instead of the 50 watt Katana. You'll be happy you did! The extra 50 watts makes a huge difference. ... show more

    • Great with electric-acoustic guitars.
Purchased for my kids who are enjoying destroying our peace and quiet with it. Easy to set up and use and we appreciate the setting for electric-acoustic guitars (which is the only kind we've connected to it so far).

    • Great amp
Adding to my Katana 50 Mk2 this is a real step up it has many more sounds and a USBC connection for control. I like the sound and it's a good size for many things. I bought this over the other modelling amps based some good experience with the last one. Apparently I can even hook the old one into it for stereo effects which is kind of neat. ... show more

    • Overall awesome amp but wireless with the adapter isn’t the best
Very user friendly and sounds great. I got it to upgrade from 2012 75w spider line 6, and the sound blows it away. Even in the crunchiest settings, my notes ring clearly. It comes with a bunch of pedal adding so you can daisy chain everything together and get the sound you want and run it straight through them amp, or add something extra on top through the amp. Gives really good volume and sounds awesome even at room playing with the 0.5 watts. I’m taking away one star because you have to buy a separate wireless adapter to download user-created tones, and the app is pretty bad considering it’s from a major brand. For this price point, the wireless should just be built in I feel. ... show more

    • Great amp
Great amp, sounds great. I wish I had bought it sooner. There is a Bluetooth adapter sold separately that plugs into back of amp, it allows you to download tones from their website. I would recommend this amp

    • I’m REALLY Impressed
I LOVE this amp! It sounds incredible in my apartment through headphones or at a 1/4 watt and it sounds equally as good at a 100 watts and running through a PA. I couldn’t design a better amp for my needs!
