All the organic tone you want with massive creative potential.

The THR100H Dual packs true dual-amp functionality into a single 5kg package. Both amps feature five custom-voiced amp types with natural, organic overdrive, Yamaha’s ultra-dynamic power amp with selectable output tube simulations and selectable class A or A/B topology, independently assignable boosters, reverbs and IR speaker simulators, as well as selectable single or true dual-discrete inputs for genuine dual-path connectivity.
Ultra Dynamic Power Amp
A great amp always has a certain something. More than just great tone, it has dynamics that breathe life into every note and give punch to every chord. With THR amp heads, Yamaha’s engineers have captured the component-level interaction between the speakers and the power amp (the murky world known as the damping factor) and tuned it to perfection, achieving a new level of performance excellence, even at low volumes. Don’t worry about hearing the difference – you’ll feel it as soon as you plug in and play.
THR100H Dual offers 5 amp types
MODERN: An “American-modded” version of the Lead amp-type, slightly more saturation and smooth, fluid overdrive
LEAD: Medium-gain British tone with rich, controllable overdrive and great definition
CRUNCH: Low-powered, bright British tone with soft touch and chiming high-end

CLEAN: Warm, rounded American tone with late breakup and incredible dynamics
SOLID: Clean, solid-state amp for zero breakup at any level
THR100H Dual offers 5 tube types
6V6: Warm, soft, round sound with rich harmonics and easy distortion
EL84: Smooth feel with soft, tactile, harmonically rich response and a pleasingly musical top end. Widely used in modern class A amps
KT88: Big, clean, tight sound with outstanding headroom—great for rock, where more pronounced note definition is desirable.
6L6GC: Strong, pronounced midrange character and bright, clean, powerful punch. Commonly associated with American guitar sounds
EL34: Pronounced midrange, tight low end and crisp treble. The most recognizable British guitar sound
*THR100H Dual does not incorporate physical tubes in its design. Instead, it utilizes Yamaha’s VCM Technology to faithfully reproduce the characteristics of each of these tube types.
Dual Amp Function
Two heads aren’t always better than one. But two amps are. THR100H Dual is a true dual-amp version of THR100H with two identical channels of natural drive and incredible dynamics. Totally independent controls, fully discrete signal paths with dual selectable inputs, and A/B/A+B switching give you access to the big dual-amp sounds that guitar tone icons have known about for years. Now it’s your turn.
Lightweight Design…Heavyweight Tone
Belying their awesome tone, stage-ready volume and the playing experience of an amp full of glass tubes and transformers, THR amp heads tip the scales at under 5kg. We guarantee you’ve never come across an amp as lightweight and compact that sounds like such a heavyweight.
BOOST Function
THR amp heads come equipped with an assignable booster that can be engaged direct from the amp or via the dedicated footswitch. With 3 incredible sounding VCM boosters, from a clean solo boost to a smooth overdrive, all selectable via the optional utility software, the THR’s boost function is ready to push your tone to the next level, right when you need it.
Impulse Response Speaker Simulation
Any amp only sounds as good as the last link in the signal chain–and in a great sounding rig, that’s usually a cabinet and microphone. THR amp heads use impulse response speaker simulation to drive a DI tone that’s indistinguishable from a perfectly mic’d cabinet. With simulations of a range of industry-standard cabinets and mics available via a USB connection with your PC, THR amp heads give you a host of options straight out of the box. But it doesn’t stop there – you can use any IR file available online, taking advantage of a huge community of tone-hounds creating custom impulses for download, or even use third party software to create your own. The difference in tone can range from subtle to significant, and the possibilities are endless.
High Resolution Connectivity
THR amp heads are equipped with XLR line outputs for connection to professional recording or live sound equipment. The speaker outputs don’t even need a dummy load, so you can disconnect your speakers for silent recording or on-stage performance without having to worry about damage to your amp.
Classic Control
The controls on THR amp heads go back to basics for quick, easy manipulation of your sound. An instantly familiar control layout along with intuitive response and interaction thanks to VCM’s component modeling means that dialing in your sound is exactly like you expect it to be. No menus, no options, no hidden functions. Just plug in and play.
Footswtich Bundled
An included dedicated footswitch is available for each model, giving you the control you need at home, in the studio or on stage. With access to boost, reverb and FX Loop functions, plus A/B/A+B switching for THR100H Dual, everything’s right where you need it. Industry-standard 5-pin DIN MIDI connectors even allow you to replace and extend the cable easily and cost-effectively.
Utility Software
THR amp heads come equipped with USB functionality that lets you connect to your computer for quick-and-easy configuration of the onboard reverb and booster effects, switching between serial and parallel effects setups, and uploading of IR data files.

    Comments about Yamaha THR100HD 100W Modeling Guitar Amp Head:

    Absolutely fantasic amp. I bought the matching 212 Cab, which gives it that low-end that I was afraid I'd be missing from my tube amps.

    I am "downsizing" from some pretty great amps - a Fender Supersonic 22 and Marshall 1974x (which have been in and out of the amp tech's many times over the years. This is NOT a reflection on Fender or Marshall - they're tube amps, it's just the way it is). I have A/B'd these amps with the THR100HD and it is so close in sound and feel that the whole tube/modelling debate really doesn't matter any more. At least to me anyway!

    All the amp sims sound fantastic (not that I can ever see myself usuing the Solid State amp) and there are plenty of options without being fiddly like other modellers. Yes, the sounds aren't *exactly* like my Supersonic or 1974x but they're not *supposed* to sound exactly like any particular amp. They are just fantastic amp sounds in their own right.

    I have seen plenty of feedback on Youtube and forums where people don't seem to "get" the THR100 heads. In my opinion the point is this: they're the "real" thing. You can gig with them, they're designed to take all your effects well, they function in a simple way like most tube amps and they're designed to "set and forget", not endless tone-chasing and loads of mediocre-sounding presets. Set it like your tube amp plug your effects in and away you go. AND it's quiet enough to practice through. Works PERFECTLY for me.

    So don't be put off with the plug-in-your-laptop-to-change-the-reverb thing. Yes, it's not overly convenient but when would you be changing the reverb type on your Marshall or Fender? Never, or you use a pedal. And the reverb/drive sims are top-notch. Personally I'd rather not have the front panel cluttered with endless buttons and LCDs.

    Can't take the smile off my face, this is a cool amp and I won't be going back to tubes. I mean it this time

    *I have no connection to Yamaha whatsoever, I'm just really happy with the THR100.

      Comments about Yamaha THR100HD 100W Modeling Guitar Amp Head:

      Received this amp today! knew what to expect as I have been playing through the 100 h version. Had the 100 h for several wks but with no pedal. Pedal was lost by previous user ,as I picked up a level 2 item. This upgraded model does have the included pedal. I am happy about that. The 100h was a 1 channel beast. This model has 2 channels and you can blend both of them. The tone and feel is as close to analog as I have ever played, digital is now able to replicate even the feel of of tubes. I own tube amps,digital amps and even a dt 50. This is the amp I will be playing for a while. When switching from channel one to two there is no latency. Many amps I have owned have a minimal delay between channels which makes them virtually unplayable. Good job with that Yamaha! Surprisingly there are not many reviews on this item. Buy if you need great tone,channel switching, no more tubes.
