Yamaha THR30IIA Wireless Acoustic Guitar Amplifier

The YAMAHA THR30IIA Wireless Acoustic Guitar 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.

Share Your Inspiration

Unique among THR amplifiers, THR30IIA Wireless has a second input with a microphone preamp, making it an ideal portable practice solution for singer-songwriters. The amp features a class-compliant USB audio interface, so you can record and produce your music using the bundled recording software from Steinberg. It also supports the YAMAHA Rec’n’Share app which lets you record audio and video of your performances and upload them directly from your mobile device to share with friends and fans.

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

It features 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.

Mobile Editor for iOS/Android

The 'THR Remote' mobile editor provides users with convenient remote amplifier operation from their smartphones. There’s no need to be directly in front of your amplifier to dial in your guitar tone. Just open the app and tap to shape your own unique sound while sitting on your sofa. PC and Mac versions of the editor are also available.

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

It features a built-in rechargeable lithium-ion battery, giving you up to five hours of playtime when you’re on the go. All THR-II models include an AC adaptor.

Designed For Your Space

The versatile sound and capabilities of THR amplifiers are reflected in an appearance inspired by decades of iconic amplifiers. Every detail of the design has been meticulously considered, for a form and style that fit perfectly wherever you play.

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.

Cubase AI/Cubasis LE

All THR-II models are bundled with Cubase AI and Cubasis LE. The Cubase AI is Steinberg’s professional music production application that offers full-fledged recording and editing. Cubasis LE is a multi-touch compatible DAW application that allows for music production on the iPad.

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-inch outputs that offer additional flexibility for recording and performance.

Rec ’N’ Share

Capture and upload your performance, Rec’n’Share enhances practicing with your music library. Add a click, change the tempo, and select sections to repeat. You can also record, edit, and mix audio and video combining the sound from your amplifier with backing tracks from your library and upload finished performances directly from your smart device.
