I've been researching amps for a couple months before buying one, and read a lot about BOSS Katana amps being a good, affordable beginner amp that is also useful as you advance. After buying the BOSS Katana 50W Gen 3, I am very happy with the amp. I just recently bought my first electric guitar and amp and this amp lived up to all my expectations. It has a huge range of tone, and I've been able to dial in the right kind of sound that I want. I only need something for playing at home, so it is plenty loud. I also opened the BOSS Tone Studio, which was very nice. It was helpful to watch a tutorial to figure out how to download it, and to intially figure out some of the dials. I was very satisfied with all the sounds that were on it already, so I didn't really change much except for adding a fuzz effect on the booster knob. Before buying this amp I had tried two other amps, one was a tube and the other was a modelling amp, both older Marshalls, and this BOSS Katana was definetly a better choice because of the range of effects and volume for a good price. Even though it's not a tube amp, I think it sounds very nice and works great. The only thing I wish had been added to the Gen 3 was bluetooth without the extra accessory. Thats a pretty standard thing now so it's a little odd for it not to be added, but otherwise I am very happy. I feel that I will be able to learn and grow on guitar with this amp for years and not want to replace it.

Great amplifier, easy to use and has a bunch of settings so you can get a lot of different sounds, plenty of distortions, crunchy metal, 50's old goldies sounds, I still have a bunch of setting to try out, I can also setup sounds in a software app that you can download and it works with the amp. Worth the money,

I am PLEASED! I recently went through a bit of an identity crisis and sold all my guitar stuff, total mistake. Now that I'm trying to get equipment enough back to get back into guitar without going bankrupt I have made purchase decisions based on more research than emotion (unlike before.) This is a great amp for beginners all the way up to intermediate and I'd argue in the right circumstance even beyond. This is the same Boss that makes the iconic stomp boxes so you have so many amp modeling avenues, multiple power stances, perfect size IMO for practice or smaller gigs, sounds great, has a wide breadth of functions, dunno what else to say. Happy to be back at it with my Boss Katana 50.

A rock solid blue-collar players amp the tones you get out of it are as close to a tube amp as I’ve found in a solid state amp it does shine in small venues. I’ve been playing over five decades it’s a budget friendly quality amp.

this is a cool amp that has a lot of cool features that i like...........i have this amp and the Fender mustang Gtx 50 with the foot pedal...........I'm a classic 50's Rockabilly player and the Fender is better for that sound/style..............this amp can get close to those sounds too ..........this isn't really a modeling amp like the Fender.......the Katana is more like a real tube amp and the Fender models tons of vintage amps............i also have the Fender mustang lt40s 40 watt amp and it also sounds a little more authentic for classic 50's Rockabilly........if you want a amp that actually sounds like a real tube amp without having real tubes the Katana get you very close to the real thing..........

Was looking for an amp to replace a Line 6 spider 20w that has developed issues with the preset controler that forced me to always connect my tablet to be able to view the presets settings. Didn’t really need a 50w amp but didn’t see any I liked in the 20 to 30w range that offered similar features, except another Line 6 but didn’t want to go with one of those again. The presets are nice and the controls are easy to learn. Haven’t even connected my tablet to it yet and don’t see any reason to rush to do so. Pros: The built in output attenuator allowing me to set the output power level is very nice. The controls are simple to use. The six presets all sound good and modifying them is easy. Cons: Standard price. I got it for a $30 discount plus another $39 for the BT attachment. If I had to pay the full price and add the BT adapter, I would have looked hard at the Fender Mustang 50GTX that would be about the same $ with built in BT. Didn’t like the rear/top mounted controls as they force me to stand up and lean over the amp to get to them. Would have preferred a top/ front control layout, but I’m getting used to this and it’s becoming less of an issue. Plus most amps of this type also have the same rear/top layout (except Line 6 and didn’t want to go there again) So I happy with the purchase and hope for years is use and would recommend.

Excellent beginner amp, especially for the price. It’s got amazing features and is more than loud enough for anyone really. It’s super functional with lots of options, but the free app you can get on your computer really takes this thing to the next level. Any tone sounds amazing on this thing from clean to crunchy distortion, this amp can do it all, and at a great price.
