The Yamaha THR10 amplifiers proved to be incredibly popular home and studio desktop amplifiers. There is something for every level of player with its small footprint and versatile range of quality tones. The Yamaha THR100H is the next step up with more power and more control than on the other THR amps.

VCM Modelling

VCM modelling is a Yamaha exclusive technology that really digs in deep to the emulation to not only give you the sound but the response you want. With 5 different amplifiers built in (Solid, Clean, Crunch, Lead and Modern) you can already access a wide range of sounds.

You can do much more though with access to 5 different power amp sections (EL34, 6L6GC, KT88, EL84 and 6V6 emulations.) and the ability to add your own cabinet impulse responses. Want to run a large gold and black British stack through a small 1x10" speaker no problem. Just load in a different 3rd party impulse response via USB and you are rocking with a completely new sound.

Front Controls

The THR100H certainly has a lot of choices when it comes to the amp and power amp options but you can actually control even more on the fly. On the front panel you have access to all the controls you would have on a regular amplifier. Gain, master, bass, middle, treble, presence, reverb and volume controls as well as an independent boost control and switch. Think of this booster control as your drive channel and you instantly have a footswitchable 2 mode setup.

Great For All occasions

This is unlike any other digital amplifier you have seen before as it is one of the first guitar amps to really take advantage of Class D power amps. This means a smaller, lighter weight amplifier that still delivers great sound.

It also means that you don't technically need a speaker load to run it safely. So if you want to run it straight via a line out in to the front of house PA or your studio set up you can do that. You can even use it for practice at home with the headphone output. 

While you will need a cabinet to run it as a traditional amplifier using the 100w power supply. Running it like this is perfectly safe and a great choice if you need to travel light.

Here's what Yamaha say about the THR100H

Featuring the incredible tone and flexibility of THR100H Dual in a compact, lightweight single-channel body, THR100H has got your back whether you're on-stage, rehearsing with the band or practicing at home. With a big sound from a tiny package, the power to dial in the details of your sound and the connectivity to plug you in wherever you're playing, THR100H bridges all the gaps.
