BOSS Katana MkII-50 12-inch Speaker 50-Watt Combo Amp (KTN-50-2)

My nephew turned me on to this amp as a good step up from my Fender Champion 20. The onboard effects eliminate the need for multiple foot pedals. 2 effects channels with 2 banks per channel provide a good basis for experimentation. If you want to setup your own effects combos, you can override the presets either directly from the panel or via the BOSS Tone Central app. The app offers thousands of effects combos you can download and install on the amp. The channels/banks can be selected using a footswitch with a TRS cable (footswitch and cable not included).Power outputs of 0.5W, 25W and 50W provide versatility for a variety of venues, including quiet at-home practice. Jacks for a power amp, aux input and headphones complete the nice features of this amp. I’ve had this amp less than a month and am already thrilled with the ease of use, sound and features.

Great sound, fun to noodle around with and experiment. Excellent practice amp with options to lower the watts and use headphones. Came with original firmware so updated it out of the gate. My only dig is there is feedback or noise when I am in lead/brown modes. I was thinking the amp was defective, but it seems you can turn noise suppression on with the software from a Windows or MacOS device. Would have liked to have a knob for that control. Also picked up a HOSA FSC-385 foot switch and TRS cable. Very affordable switching option for home use. Great price for a nice solid state amp.

I needed a small but high-quality practice amp to keep at a second vacation property (didn't want to haul my expensive gear each time). I really liked the added features of the 100-watt model, but honestly, it was just too much for this application so I settled on the 50-watt.Pros:- Excellent variety of tones possible.- Installing the Boss Tone Studio adds tremendous versatility and tweakability (I would consider it absolutely necessary). The software was simple to install on a Windows 10 laptop. A USB cable must be purchased separately however.- Really an amazing amp- especially for the price.Cons:- I tried for several straight days to duplicate my Marshall tone (which has a few Boss pedals in front). Unfortunately, I just could not get that exact Marshall tone. I can get close however.- I really wish the 50-watt MkII had the ability to save more than 4 presets. For me, this is it's greatest limitation.I highly recommend purchasing a USB cable (not included) to fully utilize this amps versatility. In my opinion, connecting the amp to a laptop is a requirement to fully unlock it's features and potential. I also recommend the Boss FS-7 footswitch which allows for quick/easy switching between the saved presets.Overall, a really fun amp to play with. For the price, this amp offers tremendous versatility and sound quality.

Can't believe this amp is selling for such a low price and still sounds the way it does. I play in a loud-a$$ rock & roll band in some mid-sized to large clubs and still usually leave the power at 25 watts rather than the 50 watt setting. The tone -- while not as warm as, say, a pushed Fender Twin costing as much as a nice, new Buick -- is still so "tube-like" that it's hard to hear the difference, at least in a live situation.A little tweaking brings out some truly luxe tones and the myriad built-in effects are just as good (at least to my ear) as the dozens of Boss pedals they can replace. I'm still using my regular pedal board, however, but only because there's no way to "push" the effects like boost and distortion with a volume pedal/guitar volume knob mix. You know what I mean: crank the volume knob but have the volume pedal dialed back at the end of the signal chain so you don't pi** off the wait staff or scare the ladies sitting down front.But even if you're not using the on-board effects, this amp is truly amazing. It seems to be extremely well-made; I'll find out if this is true once it's spent a few months bouncing around in the band trailer. The lead player in my band also has one (which is how I found out about it) and he's had his for a while now without experiencing any issues.It's just a cool, little intuitive amp with simple controls, plenty of power for most clubs and good build quality. Also, the fact it weighs a LOT less than my previous amp is a big plus! I won't go into all the features here; there are millions of vid reviews on YouTube that'll do that for ya. Just buy it and try it. If it's no good for you live, use it for a great practice amp in the living room.

There is so much to love about this amp! The build quality is solid and it’s light enough to carry easily if you need to. This thing has great range! Deep bass and really good treble. It comes with great tone options out of the box but I highly recommend you hook it up to the computer and use the boss sound studio. When you have the studio up, you can change and tweek EVERYTHING to get the tone that suits you. You also get to program the channels to almost all of the pedals offered by boss. It provides great tone at really low volume so you don’t disturb anyone but also can get quit loud! I love this amp and it feels brand new every time I use it! It is worth the money!
