Light. Sounds good. Perfect little amp.

Reviewed in the United States on February 2, 2018

Great little amp. Light, packed full of great tones that are easy to get to. I use this as a practice amp and when I go to a friends for a quick jam. At home I rarely take it off of the 0.5 watt setting, it's plenty loud enough for the girlfriend at that volume. I rarely even use the 100 watt setting when jamming 50 watts on this thing are like 100 watts on my old solid state fender 2x12. Despite being light it is very well made. Definitely deserves the Boss name. I have used the tone studio software and I set the amp up with what I like and I haven't plugged it back into the computer. I bought the GA-FCRoland GA-FC Foot Controller for GA-112 and GA-212and I basically have 9 channels to choose from at my feet. 8 are programmed into the amp and I use the panel setting as my acoustic setting, and boy does this thing let my PRS P24 sing. It sounds nearly as good as my Helix for the acoustic patch. This amp has some really good core sounds that I have come to enjoy and even emulate in my Helix.

(The amp comes with 2 really nice textured stickers to place over the GA-FC to cover the difference in the Boss vs Rolnad amps.

Boss Tone Studio NOT Working With macOS Catalina

Reviewed in the United States on October 22, 2019

The Boss Katana is a fair sounding amp. The biggest selling point for this amp is the ability to use Boss Tone Studio to make changes to the amp modeling, create chains of effects to get the sound you want. With the latest release of MacOS 10.15 Catalina, the Boss Tone Studio software will not connect to the amp. So, you are stuck with whatever sounds you currently have in your bank of presets. I went to the Boss website to get a software update. After 2 weeks, they still do not have a software update. Really ? No software updates? And this is Boss big selling point for this amp, to be able to use Tone Studio to either create sound presets or be able to download sound patches from others. Knowing the importance of this feature, it seems that Boss should have been more proactive in having their software "ready to go" within a short time of the MacOS software release. And their support says they should have it ready in about a "month". Well, glad I'm not a traveling musician playing different venues and depending on this amp for the sounds I need. Very poor planning from Boss / Roland Corporation. This is NOT the kind of support that people who buy your products depend on. I will probably sell the one I have and go to another brand.

If you’re looking for the biggest bang for your buck look no further!

Amazing amp! As loud and as quiet as you want I while maintaining that crystal clear tone. And I use a pedal board with a good bit of pedals and the effects loop works flawlessly as well as my dirt and overdrive and wah and etc going straight to the front of the amp! Previously bought a Marshall code and I did not like it and felt limited with only being able To use the onboard effects, with katana you can use the existing effects along with pedals and it sounds crystal clear! Amazing amp and an amazing price!

Sweet amp for electric and acoustic guitars

Reviewed in the United States on November 27, 2017

Verified Purchase

After much research, I purchased this amp and it is sweet. Great sound and simple to use - also like the laptop connectivity to create, modify or download tones whenever I want to play with this feature. The acoustic channel also allows the amp to easily handle acoustic, which further broadens the appeal and flexibity of this great machine.

Upgrade over the Katana 50

Reviewed in the United States on September 4, 2018

Verified Purchase

I considered both but if you want an effects loop and to use the GA-FC (foot controller) you need this vs the 50. At the .5 watt setting it works great as a home practice amp. At the 50 or 100 watt setting you can play to a crowd or with a band. The amp is simple to use and many will say it behaves similar to a tube amp but lighter and with more features. The good news is the features are easy to use, though are enhanced if you connect to a lap top. I found most of the internal Boss Pedal effects are pretty awesome and save you money since you don’t have to buy them. However, not every pedal is available and some of the options are only ok. I ended up buying a looper and a reverb pedal to complement the amp. Overall, I really like the amp. The best part is just how easy the control panel is to use. You get a few amp types including Accoustic, Clean (my favorite), Crunch, Lead and Brown. You can modify the sounds on the panel with the internal pedal options or use a preset (up to 8 which you can change). A few pedal upgrades and this would be a 5 Star. Way better than my Fender Mustang amp it replaced. There are online forums to get sound patches and there is a “sneaky amp”patch which lets you mod most of the coveted amps out there.

Best combo amp under $500

Reviewed in the United States on October 27, 2017

Verified Purchase

Really nice combo amp, not tube driven, but definitely doesn't sound like a typical solid state/cheesy modeling app. I read/watched several reviews on this amp before buying it, and it lives up to expectations. Very versatile sounding app, connect it your computer and download/tweak tones using Boss studio.
With a recent update, you can now store up to 8 onto the amp itself (was four previously, now can switch between the 2 banks of 4 by holding down the Panel button)

Amp is capable of producing quite a lot of volume, but has a switch that allows you to set it to .5w, 50w or full on 100w. Even at the half a watt setting, it is plenty loud for practicing and doesn't really change the tone when switching between the different power modes.

Quality, Feature-Packed Amp

Reviewed in the United States on April 10, 2019

Verified Purchase

We’re living our new Katana 100w amp! We haven’t even gotten to use half of the features, but the sound and ease of use is great! We especially like that you can use a foot pedal (you can’t on the 50amp) and that we can turn it down yet still keep the same tone as when it’s loud. We have even started looping now... It’s great! It’s loud enough and light enough that you could gig with it too. Plus, it has 50 customizable Boss effects as well. The possibilities are endless... I’m so glad we didn’t spend any more on buying the same pedals as we have in this one amp now!

One amp to rule them all

Reviewed in the United States on April 20, 2020

Verified Purchase

The only time this app does not amaze me is when it is off. Since purchasing this amp, I really have not used my other ones. The simplicity and the versatility of the boss katana has made showing up to gigs and practice so much easier, because I don't need a ton of pedals and different amps to get the sound and quality that I am looking for. Whether I am playing worship music for church or rock music for a gig, Blues Rhythm and Lead, classical guitar or classic rock guitar, and even some experimental sounds I can easily get the right tone I am looking for out of this amp. Absolutely no buyer's remorse whatsoever

Great amp, but has 2 usability issues

Reviewed in the United States on March 1, 2017

Verified Purchase

Pros - Sounds great. More power than you'll ever need and it can configured as a half-watt, 50 watt or 100 watt. The overdrives all sound good and the effects, especially the plate reverb, are terrific. Price is amazing, but you need to add $100 for the footswitch, as you'll see.

Cons - You really can't appreciate what the amp can do until you hook it up to a computer. You can't edit the effects or store your own patches without downloading their "Tone Studio". Also, unless you're a one-tone player, you can't gig with this amp without the footswitch unless you like touching your amp alot. The footswitch doesn't come with the amp and none of the big online music stores will have them in stock until April 2017. Oh, and it's kinda pricey ($99.99) for an aluminum box with 4 or 5 stomp switches in it.

Perfect Solid State

Reviewed in the United States on July 18, 2019

Verified Purchase

One of the best solid state amps on the market, needs little to no setup and is very straightforward with a 10 minute YouTube video background. Highly recommend for a bedroom amp and for a gigging amp. Has lots of options for sounds and all of them of good expect for the whammy. You pay for what you get, it’s not a tube amp but for $360 you can’t go wrong
