Guitarists are familiar with the tube amp stacks that sound amazing when turned up loud on a big stage, and with combo amps that are a perfect fit for smaller venues and rehearsal. THR ignored the convention that a practice amp should simply be a smaller version of a larger amplifier, creating a new “third amp” category designed around what players need when they’re playing at home.
All THR-II models feature Bluetooth connectivity for audio playback, the “THR Remote” mobile editor app, and third-party footswitch support.
THR10II Wireless and THR30II Wireless also feature a built-in rechargeable battery and Line 6 wireless receiver. Just grab your THR, your guitar, and a Line 6 Relay G10T transmitter (sold separately), and play anywhere your music takes you.

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.

The “THR Remote” mobile editor provides users with convenient remote amplifier operation from your smartphone. 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.

The THR30II Wireless and THR10II Wireless feature a built-in wireless receiver. A Line 6 Relay G10Ttransmitter (sold separately) is required.

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.

Yamaha’s patented Virtual Circuitry Modeling (VCM) technology simulates each circuit down to the component level. By modeling these components and the interactions between them, VCM realistically recreates the nuances that give boutique tube amplifiers their unique sound and feel.

Three banks of five guitar amp models offer everything from shimmering cleans through bluesy overdrive and crushing high gain. Each bank also features a unique bass amp model, mic model for electric-acoustics, and a flat voicing without any modeling, for anything else you might want to connect.
In addition, THR features dual circuits providing 8 natural, ultra-musical effects. One circuit handles stompbox-style modulation effects while the other provides delays and reverbs.
A compressor and noise gate are also available via the THR Remote editor software.

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.

THR incorporates Yamaha’s new Extended Stereo Technology to create a wide, spacious stereo audio image. Stereo tracks and studio-quality reverb combine to add a depth to your sound that belies such a small enclosure.

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.

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.

All THR-II models are bundled with Cubase® AI and Cubasis LE. 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®.

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.
