The THR series are not just smaller amps. They truly take into account what guitarists are looking for in an off-stage amp and have been designed from the bottom up with this in mind. Yamaha believe that the stage is not the only place where guitarists should expect perfect tone. Every time you play, you want to sound your best and the THR range makes this happen.

The Perfect Third Guitar Amp

Most guitarists have perfected their stage rig and many have that small set-up prepared for rehearsals and small gigs but what about every other time you play? The best guitarists spend hours off-stage practising and why should you have to sacrifice your tone? The THR series aren't just practice amps though. They are the perfect amp for everywhere else you play that's not on stage whether that be at home, with friends or even outside.

Yes, the THR5A is small and compact but that's far from the end of the story. Yamaha considered all the features guitarists were looking for in an off-stage amp and built them all into this nifty THR. High quality stereo playback is amongst these features. The analogue aux and USB connection can be used to listen to audio directly through the amp making play along sessions much easier. Developed with Yamaha's AV division the amp offers true hi-fi stereo sound. The Extended Stereo Technology creates incredible audio depth. The THR5A also has a two-way power supply which operates on AC (PSU supplied) or battery power lasting up to six hours so wherever you want to play the THR5A can go with you!

Coming bundled with Steinberg's Cubase AI professional music production application you have access to a wealth of recording and editing options. The amp works as a simple recording interface sending two stereo pairs or recording back to a computer. The clean guitar sound is sent separately from any effects which is how many modern pro studios record and makes the editing process much easier. The free THR Editor, available for download from Yamaha's website, also offers deep editing of amp and effect parameters using a computer. Other user-friendly touches include five user memory slots, tap tempo and chromatic tuner. Also look out for the Yamaha THR Session iPhone app which has a host of useful functions helping you learn songs faster and easier.

Yamaha THR Guitar Amp Sound

From the preamp to the speaker enclosure every single element of this THR amp has been designed to deliver the specific sound you need. Yamaha's Virtual Circuitry Modeling (VCM) technology means you can have the best of both worlds, less volume with cranked amp tone. The VCM doesn't just produce one sound, it models every single part of a larger amp that interact with each other to produce true tone. Turn up the master on this THR5A and it doesn't just get louder, the characteristics all change. Add to this, modelled stompbox effects and impressive reverb and delays using technology based on Yamaha's industry standard audio mixers and you have an amp that produces tone so rich you'll never want to stop!

The gold THR5A is one of the new range of amps added to the THR series designed for those guitarists who want to join the THR concept but already know and understand their specific sound. The THR5A is dialled with a specific tonal direction which focuses on the subtleties and dynamics that can be worlds apart in an experienced player's eyes.

The VCM technology precisely reproduces even the finest, almost imperceptible points of acoustic guitar sound. The THR5A's quality finish will strike a chord with those who appreciate the rich, acoustic tone captured in recording studios. Producing an impressive tone approaching that of large stage amplifiers, even at low volume, the THR5A perfectly recreates the unmistakable response and dynamics created by classic tube condenser and dynamic mics combined with studio-grade effects.

  • Condenser - Electro-acoustic optimized input with mic simulations for natural, clear tone.
  • Dynamic - The dynamic microphone setting gives the acoustic guitar a tight tonal core.
  • Tube - Electric-acoustic optimized input with mic simulations for natural, clear tone.
  • Nylon - Perfect for use with an acoustic electric classical or nylon string guitar.
  • EG Cln - Classic American clean tube amp - low gain preamp, 6L6 power section and 12-inch speaker with clear, late breakup.

The THR5A's classic retro style means the amp looks good in any home setting whilst the virtual tube illumination with simulated orange tube glow from the metal speaker grille adds a nice touch. With style and substance this is an amp you'll never want to be without. Prepare to spend a lot more time playing your guitar!
