Yamaha THR10II

It sounds amazing and dialing a good tone has never been easier. It also has bluetooth and can be used as a wireless speaker to play along or just listen to music. I can't tell you how good it sounds but there is certainly some magic going on because the sound that comes our of this tiny speaker is so spacious and clear that it blew my mind away. It sounds much, much better than the Katana IMHO.
I expected more features though, it has all the basics but lacks some nice effects that I would've wanted especially a looper. There are some features hidden in the software provided by them so you have to use it to access those features, this might be off-putting for some people but it's easy enough to do it either wirelessly from your phone or with a usb-b cable from your PC so I don't really mind.
The amount of presets to choose from is good and it's even more when using the software and all of them sound amazing.
The quality however is worse than on the previous generation, the body is now made from plastic too and is not completely metal. You can't power the amp from batteries anymore feature that I would've liked and I miss the old power switch.
Overall I would highly recommend this amp, it might not the best bang for the buck but it's certainly the most convenient solution for home use and practicing since it's so small that it fits anywhere without any compromise to the sound and it's use extends beyond guitar practice since it can be used as an amazing bluetooth speaker.

This is such a great little combo/speaker! It looks great and sounds great for a guitar and good for other audio (a bit thin in my opinion, but hey...). Very versatile product: I use it as PC speaker, bluetooth speaker and, of course, guitar combo. Also, it si quite loud - I haven't even tested it to it's full loudness in my apartment.

The only thing I miss is the Modern/Boutique/Classic switch of the bigger brother, but than again, I could buy that one. Besides, you can set this up via an app in your phone or on computer.
Oh, and maybe an effect loop would be great too, but this is marketed as a practice amp anyway.

Honestly, I haven't abused all the sounds yet, but the ones I've tried I use all the time. They are really stunning and wanting me to play all the time. What more can you ask of the guitar combo?

Use: I use this Amp as a practice amp at home, but it's powerful enough for other uses.
I love this Amp. I'm 30+, and I wanted something a little more subtle that would fit in nicely in any living room. I find it very nice looking and solid. The more I use it the more I discover about it. Now i have it set up with the USB out going to an iPad, which I use to read tabs, and I use Tonebridge for effects that go with the song I'm learning, and the sound comes back from the iPad to the Amp, with no delay, I notice. It's possible to have the Guitar input, iPad input (through USB), Aux Input and Bluetooth input at the same time!
Pros: Great look, light (but feels and is well built), sounds great, has enough effects and settings to keep anyone happy while practicing. Impressive input/output configuration.
Con: It would be nice to have the Lithium Battery one, so I could play power cable fee. It is still 100 euro more, and if I was going to buy a battery version with wireless capability, the Yamaha THR30IIW is only a little more.

I had the first THR, and now I have the second.
For home use they are great, really easy to dial in a nice tone without any menu diving. The sounds can be great with the right settings. Best of all it feels right under the fingers.

As an old skool valve head person these are just a nice easy way of pootle-ing about at home at sensible volumes and still getting cracked amp sounds and sensations.

Bluetooth is a useful addition, I rarely use the app once I have set up a few presents.
1 point deducted for having to use the app to switch the overall voicing from Normal/Boutique/Rock etc... One external button would not have broken the bank at Yamaha.

The Philip Sayce demo on Youtube is phenomenal and shows the settings he used to get those sounds. It works the same on the THRII as well :)
Never had any kind of reliability issue, if I lost it I would buy another.
This is for the THR10II without wireless, but the sounds are the same in all the range, just more volume and wireless options.
People like to compare to the Boss Katana, but really they are aimed at different customers to me.
