It is a good amp, however it has a few negatives. I play mainly rock, r'n'b, blues, funk etc. so I mostly focus on the clean and crunch sounds.
Let's start with the positive things. The amp is really light and it looks really good. So you can keep it in your living room on the bookshelf of wherever. Since it also works as a bluetooth speaker, you can use it as a speaker for the room. The sound of a bluetooth speaker when playing music is ok and it is loud enough. The amp has many features, mobile app, USB recording and all that. So, packed with features.
Sound of the amp is ok. To be honest, I expected more after reading and watching the reviews on the internet. Maybe small, BT amps with small speakers are just not for me. To my ears, Boss Katana 50 sounded much better. As did the Fender Tone Master Deluxe, but that one is much more expensive. But again, sound is not bad, it was just not as good as I expected. A little bit too artificial.
The other problem with the sound is that volume levels really differ between channels. Clean is really quiet, Crunch is louder, and the others are much louder. I expect that for same master volume/gain/volume settings to be the similar loudness. But that's not the case. Again, this is not a big problem, since you won't be switching amps all the time.
The mobile app could use some UX improvements. Not everything is logical or user friendly, but you get used to it pretty quickly.
My biggest problem with the amp was that mine was defective. It has a loud high frequency squeaking sound, especially audible on single coil guitars. On humbuckers you can still hear it but barely. I read that it happens on some of the yamaha amps, but not too often. So I was probably unlucky.
Fortunately, I bought it at Thomman, so I didn't have any problems returning it.
