Yamaha THR100H Dual Modeling Amplifier Head

The THR100H is a 100W amp head that comes with the same amp modeling technology as Yamaha's popular THR series of amps.

There's not really much to choose from in terms of amp models, but by tweaking parameters, the five voicings that it offers can cover most tones, from classic cleans to modern high gain.

There's also the ability to select between five power tube models, which include 6V6, EL84, KT88, 6L6GC and EL34 - this opens up your tonal palette tremendously, especially when you have experience with tube amps.

Another killer feature of the THR100H is its variable power output, which lets you set the power rating to 25W, 50W and 100W.


  • Power Rating: Switchable 25W/50W/100W
  • Amp Models: 5 Amp Models, 5 Output Tube Models
  • Effects: Reverb, Boost, Noise Gate and IR Speaker Emulation
  • Controls: Amp Model, Booster, Gain, Master, Bass, Middle, Treble, Presence, Reverb, Volume
  • Input: 1 x 1/4"
  • Output: 1 x 1/4" TS, 1 x 1/8" (headphone), 1 x XLR (Line out)
  • Extra Features: Built-in Power Attenuator
  • USB: Type B
  • Weight: 8 lbs.

The top two reasons why users love the Yamaha THR100H include sound quality and portability. Many are blown away by how they can tweak the tone of the amp to whatever they want it to be, especially when used in conjunction with the editor software. Most of the comments point to its clean and slightly overdriven tones, but there are also plenty of comments who prefer the other side o the amp. Build quality is also noteworthy, with many describing it as top notch and roadworthy. Speaking of roadworthiness, there are plenty of users who are now gigging with this amp with great results.

While its sonic complexity enamors many users, there are still a few who wish for a more intuitive control setup, like having special buttons for each slot.

Those who are looking for a versatile, compact and roadworthy amp will find the THR100H appealing.
