Yamaha THR 10 & THR 10C

Yamaha THR 10

Yamaha THR 10

A couple years ago I sold my Fender Princeton Chorus guitar amp and purchased a Yamaha THR-10.  These are not even the same type of product, so why the switch?  Well, I’m a hobbyist and I don’t play my amp in medium to large venues. When I play for my church, I use an acoustic into a mic or DI.  I never played the 120 watt Fender combo much at home because level 3 on the volume knob was already too loud.  And my jumbo acoustic produces plenty of volume for small to medium rooms with no amplification and sounds way better without being plugged in.
But I am starting to get into playing electric guitar, and they don’t sound very good unplugged. I wanted more variety in my guitar tones but still wanted a high level of quality in the tone.  The Yamaha THR had several things that appealed to me:
1. High sound quality: Co-developed by Yamaha Hi-Fi and Yamaha Musical Instruments. The guitar amp models are very accurate, organic and real sounding, and they do respond to your playing dynamics. This is a modeling amp, not a real amp, and modeling amps can have trouble getting this right.
2. Full range speakers: Dedicated guitar amps have great mid-range sound, because that’s where most of an electric guitar pickup’s tone is. But try plugging your mobile device into a regular guitar amp and playing an mp3 song. It sounds muffled, boomy, and generally lacking in definition. But the THR sounds great with pre-recorded music and acoustic guitars alike.
3. Acoustic setting: I could play both my acoustic and electric guitars through the amp. I’ll say the acoustic setting is decent with a piezo pickup-equipped acoustic plugged in. Much better with the James Tyler Variax guitar set to an acoustic model. Line 6 has done an amazing job modeling a miced acoustic.
4. Small, portable size: I’m not crazy about it being only 10 watts, and would have preferred 30 to 50 watts. But I have to admit I have the volume around the halfway point most of the time, and it can get loud enough to hurt your ears at close range. The form factor makes it easy to set on a desktop and tweak comfortably from a chair. I can put the power adapter and guitar cable in my gig bag or case, and the slick handle on the THR makes it easy to carry.
5. Recording interface: The THR can connect to the computer via a USB cable, which allows you to do several things.
  • You can record straight into recording software with no DA/AD conversions.
  • You can send music from your computer to the THR through USB and control the “Guitar” and “USB” volumes separately.
  • While sending your guitar signal into a DAW, you can use processing plug-ins on the guitar tone, and hear the result through the headphone jack on the THR.
  • Also, you can use the THR editor software to get more in-depth editing functions for your saved presets on the amp itself, or download and install presets others have created.
There is one quirky thing with the sound projection. When the speakers are aimed directly at you, there is a unbelievably wide stereo field from such small speakers so close together. I honestly don’t know how they did that, but it sounds awesome when you sit in front of it. But when I play standing up, with the THR on the floor, in a small hall that has some echo, it sounds muffled to me, and I have a hard time detecting what my playing dynamics are doing when playing with other instruments. I probably need to put it a few feet behind me on a tall stand so that the sound passes my head on the way to the audience. Granted, this was made to be a practice amp for the living room, and it isn’t geared for performance. But the sound is so good and volume acceptable for playing for small groups, so I use it that way sometimes.
A novelty feature that in no way affects performance is the orange glow meant to imitate the glow of tubes in a real tube amp.  It slowly brightens when you turn the amp on, just like a tube warming up.  It’s kind of cool and that’s why I shot these photos the way I did.
The THR is a modeling amp with built in effects like reverb and chorus, all of which sound very high quality. So how does it compare to software amp simulator and effect plug-ins? I’m probably not the guy to make an objective judgment, just because of my lack of experience and low skill level, but I did try out trial versions of several popular guitar amp sim/effect plug-ins (I don’t want to name names). After hours of tweaking software-based amp sims, when I switch over to the built-in THR processing, it always sounded more organic and real. Only 5 amp models, but they sound amazing. Yamaha really took the time to get it right.

Then a few weeks ago I learned that Yamaha had released the THR-10C (and THR-10X) not long after I purchased the THR-10.  The THR-10 has a wide range of tones from clean to screaming distortion. Because I play mostly clean and crunch tones, I only used 2 of the 5 electric amp models 90% of the time.  When I found that the THR-10C had all cleaner, tube amp models, I put my 10 up for sale and purchased a 10C.  I like it much better because I find all 5 models on the 10C useful. I can still get screaming distortion if I crank the gain higher, but there is a whole range of clean and semi-clean tones on each model that have a very expressive and rich sound. I love it!  I have a PRS SE Soapbar Singlecut with P90 pickups which sounds awesome through the THR-10C, and I just got a Line 6 JTV-59 Variax guitar which can put out an astounding range of tonal variation. Modeling guitar, meet modeling amp!
So “THR” is a sort of acronym for “third” amp.  Yamaha reps say that most players have a big stack for gigging, a small combo for practice or smaller venues, and this was made to be a home-friendly practice amp with extra features.  It really is true you can get screaming distortion without disturbing sleeping children down the hall, but at that point I just plug in headphones. I guess I’m not the typical target market.  I don’t have bigger amps because I’m not a gigging musician, but rather a hobbyist who plays at home and records music on the computer. The THR is my ONLY amp right now.

Yamaha made up their own names for the amp models, but these are based on real amps. Obviously, some of the amps they modeled don’t all have the same knobs, so they’ve taken some artistic license.  They are proud of the fact that they have modeled at the individual component level (tubes, circuits, transistors, etc.), rather than just modeling the sound. So the amp models respond to tweaking and playing just like real amps.

Yamaha THR 10C – Effects & Output

My favorite two effects are the hall reverb and the chorus. They sound very high quality, and all these effects can be edited more in-depth using the computer software. Unlike some products I’ve come across, everything about the THR says “quality”, from the construction to the sound.

So what about modeling amps and guitars?  So far I think the models don’t always sound exactly like the real thing, but when the sound and tonal quality is this high, I don’t really care.  Some people may be fooled in a blindfold test, others might not. If I find the sound useful and pleasing, it doesn’t have to sound exactly like the real gear it’s imitating.
Thanks to Yamaha for a genius product, and I can’t wait to see what they come up with next for guitar players.
