What is the YAMAHA THR series? Its appeal and evolution

The YAMAHA THR series is"A desktop guitar amplifier that lets you enjoy authentic sound at home"It first appeared in 2011 as a amp for home use, separate from the large stage amps and rehearsal studio amps. It was a huge hit, and inspired other companies to develop competing products, creating a new category in the industry.

Its sleek design and compact size that blends in with your home decor are also reasons for its popularity.

The original THR had a cream-colored retro body with built-in stereo speakers, reproducing realistic tube amp sound even at low volume. It also had a wide variety of amp types and effects using modeling technology, and even USB audio functionality, and was described as "an innovative amp that overturns the common sense that small amps = poor sound." When you turn on the power inside, an orange light that resembles a vacuum tube lights up, which is a nice touch.

The long-awaited second-generation THR-II series was released in 2019. It has been significantly upgraded by brushing up on the well-established sound and design of the previous model, while also adding new functions such as wireless functionality (guitar wireless and Bluetooth) and a built-in rechargeable battery."You'll want to play it anytime, you'll want to play it forever."It has become even more popular as an amplifier.

THR Series | Features and reviews of each model

YAMAHA THR5 (current smallest model)

Product Features

Ultra compact and battery powered
Its small body is 27cm wide and weighs 2.0kg, making it easy to carry around. It can run for about 8 hours on 6 AA batteries, so you can easily take it with you between rooms or when traveling. Its versatility makes it easy to use at home, in waiting rooms, and outdoors.
Simple design and intuitive operation
It has five amp types and effects, and the tone can be adjusted with just one tone knob. Some say that the ease of being able to start playing the guitar without having to make detailed EQ adjustments is irreplaceable. The ease of being able to pick up the guitar and make sounds right away is popular with beginners.
Good sound even at low volumes
Despite its small size, the stereo speakers deliver a realistic sound. Even when you turn down the volume, the sound doesn't get thin, so you can enjoy a rich tone even at home. It has a reputation for being "well-packed for its size," and it also has a full range of built-in effects. The clean sound is very good with little noise, and the distortion sound is also well-played.

The THR5 is a classic mini amp that continues from the original THR series. Equipped with the minimum necessary functions in a compact body, it pursues convenience as if "small is justice". It is easy to handle for home practice and can be battery-powered, so it is perfect for those who want to play outside of their rooms. Although the freedom of sound creation is inferior to the higher-end models, it is designed to produce good sounds intuitively, meeting the needs of those who have just started playing guitar or who want to play without complicated settings. The stereo effect of the 8cm x 2 speakers and Yamaha's unique acoustic technology realize three-dimensional sound even at low volume. It is an introductory amp that many people say is "worth buying".

Positive reviews

"The clean tone is excellent and there is no noise. It produces a solid sound even at low volumes, making it perfect for practicing at night."
"I was surprised at the sound quality for something this size. The sound is incomparable to small amplifiers with only so-called AUX inputs."
"The overwhelming advantage is the ease of playing without having to connect to a PC or smartphone. If you're not satisfied with the price and sound, there's nothing else to buy."

Negative reviews

"Because the device is small, there is a limit to the bass it can produce. Physically, an 8cm speaker cannot be denied as being weak in terms of deep bass."
"It's difficult to create detailed sounds with just one tone knob. You can edit on a PC, but it's unfortunate that you can't save presets on the unit, which makes it hard to use."
"Some people said the body lacked a sense of luxury and felt cheap. Some people also felt the sound was digital (hard), and some said it was difficult to capture the nuances of picking."

YAMAHA THR5A (Acoustic model)

Product Features

Acoustic guitar microphone simulation
Five types of microphone models are built in (condenser/dynamic/tube microphone style, etc.) to make the line sound of an acoustic guitar more vivid. It suppresses the piezo smell and gives you a natural and clear acoustic guitar sound as if it was recorded with a high-end microphone. It also has a nylon string mode and a clean setting for electric guitars, and is excellent for delicate expression.
Lightweight and easy to carry
The basic structure is the same as the THR5, and it is compact in size and weighs just 2.0kg. The design is champagne gold, giving it a stylish look. Of course, it can also be powered by batteries, and its ease of use for outdoor street performances is a major benefit. It is small enough to fit in a backpack, making it ideal for traveling or for small concerts.
Highly functional interior design
Its tasteful design, reminiscent of an antique radio, is popular because it blends in with the interior of a room without looking like an instrument. When it's turned on, a warm orange light shines out from inside, satisfying the desire to own it. It also comes with a metal handle, making it both good looking and practical.

The THR5A is a derivative model optimized for acoustic guitars. The microphone simulation function gives a rich spread to the line sound of the electric acoustic guitar, achieving a natural tone "as if it was recorded with a microphone in a studio". It is lightweight and compact, so you can take it out not only for practicing singing and playing, but also for street performances and cafe performances. It has a high design and looks stylish even when left in a room, so some people use it as a small audio device for music playback and interior decoration. However, since it is mainly in the clean to crunch range, it is not suitable for rock electric performances that require intense distortion (for such purposes, the regular THR5 is recommended).

Positive reviews

"It's great that it's light and compact. It's easy to carry and the weight isn't too heavy to hold in your hand. At worst, you could even fit it in a backpack."
"I love the stylish antique design. It's a look that you'll grow to love even if you just leave it in your room, and when you turn it on, the orange light gives off a nice atmosphere."
"It's battery-powered so you can use it anywhere. It's great that it can work without an outlet in case of emergency (it's great for playing outdoors)."

Negative reviews

"The disadvantage is that it only has one guitar input channel. If you want to sing and play while using a microphone, you can't do that with this amp, so its uses are limited."
"There's nothing particularly bad about it... If I had to say one thing, it would be that the sound is too clean. It doesn't hide any imperfections, so it really tests your skill (laughs). If you want to have fun with rock-style distortion, the THR5 is a better choice."
"The distortion is not enough for use as an electric guitar amplifier. The clean tone is excellent, but if you want a high-gain tone, there are limitations (if you can accept the purpose, there is no dissatisfaction)" (← a common opinion of multiple users)

YAMAHA THR10II (basic current standard model)

Product Features

A wide range of amp sounds
The compact body is equipped with 15 types of guitar amp models, covering all genres from clean to high gain. In addition, it is equipped with a total of 24 sound variations, including bass, acoustic, and flat (full range) settings. Each amp type can be switched between three modes: "MODERN/CLASSIC/BOUTIQUE," so you can enjoy three different personalities with one amp.
Extensive effect functions
Equipped with 4 types of modulation such as chorus, flanger, phaser, tremolo, and 4 types of delay and reverb. Compressor and noise gate can also be used by editing in the app, covering all the necessary effects. You can create a variety of sounds without needing a multi-effector, and some people are happy to say, "There are so many effects!" Once you have created the sound you like, you can save up to 5 presets on the main unit and call them up with one touch.
Bluetooth & Audio Interface Function
This unit supports Bluetooth connection, so you can wirelessly play music from your smartphone or PC and jam, or use the dedicated app "THR Remote" to remotely control the amplifier settings. In addition, all models are equipped with an audio interface function via a USB terminal, so you can easily record by connecting to a computer or iPad. With the Cubase AI / Cubasis LE software included with the purchase, you can also try your hand at full-scale recording and music production.

The THR10II (Ten-R-Ten Mark Two) is the standard model of the current THR series. It has evolved significantly from its predecessor, the THR10, and is characterized by its versatility in responding to the latest needs, such as the variety of amp models and effects, as well as Bluetooth compatibility. With a rated stereo output of 20W, it delivers more than enough volume and power for home practice. The size is a size larger than the THR5, but the low-frequency range is increased, and it is said to have a rich sound that is ``amazing and does not feel cramped like a small amp at all.'' The price is also reasonable considering the functions, and it is a well-balanced model that you can say ``If you are unsure, this is the model to start with.'' Since it is for indoor use only (not compatible with batteries), if you want to play without being tied down by cables or power sources, we recommend considering the higher-end Wireless model.

Positive reviews

"It has a wide range of sounds that can be used for any genre, and sounds great. It can also be used for listening to music and can be taken anywhere, making it a versatile amplifier."
"Even though it's a small speaker, the bass has great extension. It has a wider bass range than the THR5 and doesn't have the dullness that's typical of small amplifiers. It's amazing."
"The amp distortion is natural and not overly artificial. It has a natural drive feel like a real tube amp, and doesn't feel like it's modeled."

Negative reviews

"It's a bit pricey for a home amplifier. It's convenient and has good sound, but some people say that spending nearly 5 yen is a hassle... (The regular model is in the 3 yen range, but the Wireless version is expensive.)"
"I felt that the midrange character was a little strong for many amp types. There were times when the thick midrange was distracting, so some people might not like it."
"Some people say it's inconvenient that you have to use the app to change amp modes, since there's no switch on the amp itself. But others point out that it's not a problem if you just set it as a preset, so it really depends on how you use it."

YAMAHA THR10II Wireless (Advanced model with built-in wireless function)

Product Features

guitar wireless function
The unit has a built-in wireless receiver, so you can play without the hassle of cables by simply inserting a compatible Line 6 Relay G10T transmitter (sold separately) into your guitar. It's free from the hassle of having to connect and wind a cable every time you practice, and the fact that you can just flip a switch and play whenever you want is incredibly convenient and well-received.
Built-in rechargeable battery
Equipped with a lithium-ion rechargeable battery, it can be used continuously for about 5 hours on a full charge. You can enjoy the THR sound to the fullest even outdoors or in places without a power outlet. Of course, it can also be operated with the included AC adapter, and you can switch depending on the usage situation. Some people say that they can carry it around and play it anywhere in the house, and once you experience the freedom of not being tied down by cords, you'll be hooked.
Basic specifications are the same as the THR10II
Apart from the wireless function and battery, the amp/effect configuration and output are the same as the THR10II. The 20W stereo output, number of amp models and sound quality are also exactly the same, so there's no need to worry about the difference in sound. If I had to point out a difference, it would be that the weight is 0.2kg heavier (3.2kg) due to the rechargeable battery, but portability is still adequate.

The THR10II Wireless is a higher-end model that adds wireless-related functions to the previously mentioned THR10II. Freed from the hassle of cable connections, you can place the amp anywhere in the room and play. The built-in battery makes it practical to use it outdoors, and the freedom to "play wherever you want, whenever you want" is an irreplaceable benefit. The essential sound is the same as the regular version, and the functionality is truly comprehensive. The downside is that it is expensive, about 1.5 times the price, but this model is highly recommended for anyone other than those who don't need convenient functions and want something as cheap as possible.

Positive reviews

"It's great that both the guitar and the amp can be made completely wireless! I can play whenever I want, so it's easier to practice. It also gives me more freedom in arranging my room."
"You can play while listening to songs from your smartphone via Bluetooth, and it supports foot switches so you can switch effects with your feet. It's packed with features that make practicing at home easier."
"It can run on battery for five hours, so you can carry it around the house and play it anywhere. It's great not being tied down by wires... it's a life-changing convenience."

Negative reviews

"It's good, but expensive. Some people say that it's hard to afford the wireless function and the actual selling price of over 5 yen. If you don't need it, the regular version may be enough."
"Some people are concerned about the battery life. Battery degradation is inevitable with long-term use, so some people seem to be concerned about the future replacement costs." (←concerns expressed in user forums, etc.)
"The weight of the device has increased only slightly, but it's still over 3kg, so it feels quite heavy when you carry it around in your bag. However, it's not so heavy that you can't carry it..." (←from a personal blog)

YAMAHA THR30II Wireless (top-of-the-line, high-output model)

Product Features

30W high output and large speakers
Boasting a stereo output of 30W (15W + 15W), the largest in the THR-II series, it easily covers volume levels that are more than enough for home use. The speakers have also been increased in size to 9cm in diameter, further improving the impact of the low-frequency range and the spread of sound. This powerful sound will come into its own when you feel that the 20W THR10II is not enough, or when playing in a large room or outdoors.
Equipped with a line out terminal
It is the only model that has a stereo LINE OUT output (rear terminal), which allows you to connect it directly to a mixer or PA and play it through external speakers. This allows you to record with higher sound quality when recording at home, or connect it to a PA at a small live show to use it as a monitor and simple amplifier, making it expandable enough for professional use. In fact, it has been praised for its ability to produce high-quality sound even on stage or in recording.
Fully wireless compatible and improved operability
The basic functions are the same as the THR10II Wireless, and the wireless reception and built-in battery allow for a cable-free environment. Furthermore, only the THR30II is equipped with an amp mode selector switch on the main unit (switchable between CL/BLUES/MODERN), allowing you to use the three modes without the need for an app. Another consideration unique to the top-of-the-line model is that it allows for more intuitive operation.

The THR30II Wireless is the flagship model of the THR series. While retaining the convenience of wireless functionality, the output has been strengthened to 30W, so it surpasses other models in both volume and sound pressure. It has ample sound even in spaces larger than a living room or outdoors, and some people are surprised by the realism of the sound, saying, "It's hard to believe that you're playing an amp at home." Another major strength is that the LINE OUT is equipped with an all-purpose function that can be used for everything from home recording to small-scale live performances. The price is about 6 yen, the highest in the series, but you will get a rich experience that is worth it. Some people say, "If you're going to do a street live performance without drums, the THR30II might be the only choice," and it is highly regarded as a versatile amp that covers everything from hobbies to full-scale use.

Positive reviews

"As you would expect from the top of the THR series, the sound density is second to none. It's fun to play both electric and acoustic guitars, and the quality is satisfying even at low volumes."
"Even when played in the living room, the sound is so three-dimensional that it envelops you. It's so realistic it feels like you're playing through large monitor speakers, and it will change the way you think about practicing at home!"
"The line out is surprisingly useful. It can serve as an audio interface for home recording, and in an emergency you can connect it to a PA for mini gigs in small venues, so it's very useful."

Negative reviews

"The functionality is impeccable, but the price is still high. If you buy a transmitter, it will cost you nearly 7 yen, and some people say that it is too expensive for beginners to buy..."
"At 4.3kg, it's the heaviest in the series. However, it's still light compared to carrying the head and cabinet, but it's a bit too big to carry in a backpack." (←From a user review)
"20W is enough for home use, so 30W may be a bit overkill. If you live in an apartment building, you may find the output is too much." (←Comment from a musical instrument store employee)
