Yamaha THR100HD Amplifier

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
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.

This amp was purchased for a specific job requiring managed volumes. The amp met/exceeded expectations and will probably be more useful than I had hoped for other situations as well. You no longer have to feel like you are wasting rehearsal hours on expensive NOS tubes with this amp. I have not explored the line outs or the stereo effects loop yet, but I feel that they will be acceptable, as well.

I have had this amp for a little while now and the range of tonal options is amazing. Handle Pedals well, able to split pedals in the loop between 2 amps. Jamming on the same amp with 2 players is fun, especially if it is your only amp. Loud as you need with the 2x12 cab and soft enough when switched down to 25 watt for bedroom or studio.
Buy this amp now!!

First off, I've been a huge fan of Yamaha equipment for over 35 years. Their products are extremely well made and reliable as hell. This amp has all the features I was looking for, in terms of flexibility. 5 tube selections, 3 power settings, 3 overdrive settings and 4 reverb choices which can be set differently for each of the two amps in the Dual Head!! This is an amazing piece of engineering folks. And you never have to re-tube again. The clean and overdrive sounds are as good as any tube amp I've ever played through and the Dual Amp design allows you to create some very cool stereo effects with the right speaker setup. Operation is simply and easy and your tone remains consistent throughout the entire range of volume settings. Setting up the internal booster and reverb is easily done if you have a Laptop and the right USB cable. Get your hands on one of these things today and it will completely change your perception of solid state amps forever and it will take your sound to places you didn't know it needed to go.
