*THR Head 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.

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. *Only for THR100H Dual

Belying their awesome tone, stage-ready volume and the playing experience of an amp full of glass tubes and transformers, THR head amps tip the scales at under five kilograms. We guarantee you’ve never come across an amp as lightweight and compact that sounds like such a heavyweight.

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.

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 Head uses 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 Head gives 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.

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.

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.

An optional 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 FXloop functions, plus A/B/A+B switching for THR100HDual, 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.

THR amp heads come equipped with USB functionality that lets you connect to your computer for quick and easy configuration of the on-board reverb and booster effects, switching between serial and parallel effects setups, and uploading of IR data files.

Almost all of the classic tube sounds of the last few decades have been a product of the synergy between a high-quality amp head and a dedicated speaker cabinet designed to complement the unique sonic characteristics of the amp. The THRC112/THRC212 are no different, and have been crafted and tuned specifically to accommodate the versatile amp, speaker, and valve simulations of THR amp heads.

Specially designed carry bag and compatible with THR100H Dual and THR100H. It has plenty of space for footswitch, footswitch cable and power cable and also built-in outter pocket for accessories.
