The Original Acoustic Desktop Amp  

Your Acoustic Experience, Amplified

The THR30IIA Wireless amplifier is designed specifically for acoustic guitarists. Realistic microphone modeling and onboard effects offer inspiring tones as though your guitar’s sound was captured in a professional studio and the compact size and classic style fit naturally into any environment. With Bluetooth support, a rechargeable battery, and a built-in Line 6 Relay wireless receiver, you don’t have to worry about wires. Just focus on the music, wherever you want to play.

Acoustic Mic Modeling

Realistic models of boutique condenser, dynamic, and tube microphones make your guitar sound like it was recorded in a professional studio. There is also a voicing optimized for nylon-string guitars, and a flat mode without additional coloration.


Stereo Imager

The Stereo Imager switch widens the signal from the Guitar input providing an atmospheric stereo field. The Wide and Wider settings increase the effect, accentuating vocals as the signal from the Mic/Instrument input remains in the center of the stereo field.

Hi-Fi Audio Technology

The THR guitar amps were developed with Yamaha’s award-winning AV division to offer true hi-fi stereo sound. The exclusive, specially-designed speaker enclosure is optimized to handle both guitar and audio playback sound, making the THR uniquely capable of giving you amazing tone for both your guitar and your favorite music from a compact, portable amp.

Microphone Input

The Mic/Instrument input makes the THR30IIA Wireless amplifier ideal for singer-songwriters.

Connect a microphone and adjust the independent volume and reverb controls to balance perfectly with your guitar for an inspiring ‘fully produced’ sound.

Bluetooth Support

All THR-II models feature Bluetooth functionality for audio playback, the mobile editor app, or third party controllers (sold separately) to call up your own customized presets without the need for any manual parameter adjustment or cable connection.

Integrated Audio Interface

The new THR-II series amps are USB Class Compliant, allowing easy connection with PC/Mac and mobile devices without the need to install drivers, so that you can easily use your THR-II as an audio interface for recording.

*ASIO driver for Windows can also be used.

Line Outputs

Among original THR owners, one of the most frequent requests was for the ability to take the THR tones they loved anywhere. The THR30II Wireless feature stereo 1/4” outputs that offer additional flexibility for recording and performance.


Built-In Wireless Receiver

THR30IIA Wireless features a wireless guitar receiver, providing seamless, high-quality wireless capability when used with a Line 6 Relay G10T or G10TII transmitter (sold separately).

Rechargeable Battery

THR10II Wireless and THR30II Wireless feature a built-in rechargeable lithium ion battery, giving you up to five hours of play time when you’re on the go.

All THR-II models include an AC adaptor.
