Outstanding Acoustic Tone in a Compact Package

Boasting three microphone models, onboard effects, Bluetooth, wireless input capabilities, and selectable stereo imaging, the Yamaha THR30 II A packs plenty of functionality into an ultra-portable form factor. This 30-watt combo amp is loaded with a pair of 3.5-inch speakers, which are laid out in a stereo configuration with selectable imaging options. The Bluetooth support allows you to stream hi-fi backing tracks from your smartphone. While you play along, plug a microphone into the high-quality preamp and belt out some killer vocals. The Yamaha THR30 II A includes plug-and-play USB connectivity for recording and playback, along with a built-in wireless receiver for performing cable free. Read on: there's plenty more to discover within the Yamaha THR30 II A.

Choose from great microphone models

To help you get the perfect tone, the THR30 II A has five selectable voices for you to play through. You get three excellent microphone models that shape your pickup's raw sound into a convincing reproduction of a studio sound. Whether you prefer the sound of a tube, dynamic, or condenser microphone, you can take it with you for your next performance. There are also settings for nylon-stringed guitars and a Flat setting for a pure amplified tone.

Bluetooth support for playback, preset editing, and much more

The THR30 II A's Bluetooth support lets you take advantage of some seriously impressive capabilities. You can stream audio from a music service, thereby allowing you to play along to your favorite tracks. And with Yamaha's THR Remote app, you can dive into the THR30 II A's settings, craft your own presets, tweak the EQ, and assign effects. Since the amp has five settings recall buttons, you can take five of your favorite tones with you anywhere you go.

Take your music anywhere

If you ask the product testers at Sweetwater, one of the most useful features of the Yamaha THR30 II A is its rechargeable internal battery. With it, you can grab your smartphone, amp, and guitar and head out — you can jam in the car, under a tree in the park, and anywhere else you can imagine. And since it's equipped with an XLR input, a high-quality microphone preamp, and stereo line outputs, the Yamaha THR30 II A is a mobile performer's best friend.

Wireless made simple

Thanks to its built-in wireless receiver, the THR30 II A Wireless Acoustic amplifier, makes cutting the cord blissfully simple. Fire up your Line 6 Relay G10T transmitter (sold separately), and you’re ready to go. There's no setup fuss, fumbling with batteries, or menus — just plug-and-play simplicity. You can even charge the G10T in the amp's input jack!

Wow!!

I have not plugged into any other amp since I received my Yamaha two weeks ago. This amp is so versatile I can use it for home practice and band rehearsal, as well as plug it into a PA for performing. Love the rechargeable battery that lasts up to 8 hours - certainly long enough for either practice or a gig. Very easy to haul around as well. I highly recommend the nylon case made for the amp.

Easy access to the controls. Storage for easy access to five presets. PLENTY of volume. Love the retro look of the backlit cream colored chassis as well.

I did my research - hours of reading and watching 'tabletop' amp comparison videos. In this class, this is the amp you want.

Great for our intended use.

I've had this unit for over a month and really enjoy it and so does my girlfriend. We primarily use it in the house to enjoy playing songs with different sound variations. Given that and all of its features, it is well worth the money (IMHO). But like any product; use it outside of its capability and you get some of the harsh reviews on it. I think some people fall into the advertising trap as well and expect more than the product actually delivers. And no, it is not perfect. My personal thoughts:

* overall great sound quality
* volume was more than adequate for indoor use, while outdoor was acceptable given its size
* sound variations are plentiful (and using headphones really becomes immersive)
* Bluetooth is great for use like background tracks or just for streaming music
* G10T works great, though as with any wireless device of this type, I had some interference pending on playing location
* The app is simple to use and offers more sound flexibility over the dials
* microphone and singing along...OK, my girlfriend singing since I can't sing for shi* sounds great with the options to alter the sound (which still does not help my voice).
* portability and battery life is a bonus

If you take the unit as designed and all of its features, it deserves nothing less than a 4-5 star rating. Can the app be better; yes and I expect updates (like every app out there). Would I prefer dials over using an app; somewhat, but you can only have some many dials for the form factor, so kudo's to Yamaha for provided us a means for more sound flexibility. Do I wish it had more bass...yes, but this is a personal preference and the target is for acoustics after all.

Oh and Sweetwater as a company...it's truly the best. They worked over a month on an issue I had (turned out to be user error) and even did an exchange. This company exemplifies what customer service and satisfaction is all about.

guitar tone is not what I expected

I had high hopes for this amplifier, having previously owned a THR5A, as well as a THR10C, and a THR10ii. During the past year, I've been using the 10C as a home PA, utilizing a small mixer plugged into the line input jack. It has worked very well in that capacity, with the 10ii amplifying my electrics and the 5A for the acoustics. I purchased the THR30iiA in the hope that it would provide a battery operated portable system to use at small social gatherings.

The vocal channel is rich sounding, even without the mixer, but the tone on the guitar channel is very brittle sounding when compared to the THR5A. The low end is very disappointingly thin and lacking in body, even when utilizing a Fishman or LR Baggs preamp to color the tone. I spent a couple of hours making adjustments in THR remote, in an attempt to duplicate the tone I get from the THR5A, but I've been unable to come anywhere close to finding a match.

I do get a decent tone with an electric in the flat setting, using a TC Electronics G System to color the tone to my liking. Hopefully, continued experimentation will find a better acoustic tone.

Updated Review

I'd like to update a segment of my previous review. The Bluetooth issue (not going to zero) seems to have been resolved. I personally don't know what changed as two separate devices exhibited this anomaly. But hey... it works now. Also, upon reading my previous review, I may have been overly harsh, namely the 30 watt point. In all, it's fine for it's intended purpose. And I do think making it a modular system is feasible even with some of the preamp noise, which I'll probably end up doing once we're all out gigging again.
Seeing how it's essentially several things all crammed into one elegant housing, I DO recommend it (another change from my previous review) now with some of the teething issues resolved.
Happy playing.

Not what I expected

After owning one of Yamaha's older models the THR10 (which I still love) I had high hopes when I bought this one.

I was expecting since it has more wattage then the THR10 it would be louder. But after playing them side by side it really isn't. Which is super bizarre considering one is 10watts and the other is 30.
So don't expect this to be a loud amp. It works best as a desktop amp and it does that well.
Now I have used it busking on the street I had to turn it all the way up, gain 100% and volume. And it still barely hung in there. My friends Roland street cube blew it out of the water.

The tone is alright if you are just using it for acoustic guitar, still found the the THR10 to be better. However I never found any use for the other sound settings (nylon, tube, etc). The "Flat" setting is the best for acoustic guitar in my opinion granted everyone's pickups are a little different. But also in the flat setting you can get the most volume.

I mean the main con I guess is the volume, I just expected more from such an expensive amp. It does alright just jamming away in your room, it's not a great busking amp. If you plan on just using this strictly as a practice amp I think you'll be pretty happy with it. If you plan on playing out at all the lack of volume might let you down.
