Introduction Introduction
Finally.
The amp you’ve been waiting for.
Finding the perfect tone is a journey– searching for boutique pedals, making
custom cables, swapping out speakers, experimenting with different tubes–
each step a discovery that leads down a new creative path. With THR amp
heads, Yamaha has designed innovative, flexible amplifiers that will play an
integral role in your sonic journey to find that perfect sound.

The tubes they are a-changin’
The choice of power tubes in any amp can make a vital dif-
ference. From the warm, soft, rich harmonics of a 6V6 to
the pronounced midrange and tight low-end of an EL34,
changing your tubes changes your amp. However, this
can be difficult; selecting the right tubes, swapping them
out and re-biasing your amp takes a lot of time and mon-
ey, and it’s easy to get wrong if you’re not entirely sure of
what you’re doing. THR amp heads feature new VCM sim-
ulation that allows you to pick from five classic tube types
for any amp model with nothing more than the flick of a
switch on the rear panel. You can even choose from the
smooth compression, soft touch and old-school distortion
of class A, or the tight bass response, greater headroom
and increased dynamics of class A/B for each tube type.
That sound
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.
Five amps at the flick of a switch
Whether you use pedals for your overdrive or just crank up
your volume control, one great amp sound is where it all
starts. Sometimes though, you want to take your sound in
a new direction with something just a little different. THR
amp heads feature a single-channel design with five dis-
tinct custom amp types from solid state through to modified
high-gain, all tuned to sound amazing whether you want to
get your drive from a pedal or your amp.

Double trouble
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 incredi-
ble 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.
Great tone, on an impulse
Any amp only sounds as good as the last link in the sig-
nal 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.
The finishing touch
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.
Classic control
The controls on THR amp heads go back to basics for
quick, easy manipulation of your sound. An instantly fa-
miliar 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.
Kick it into high gear
THR amp heads come equipped with an assignable booster
that can be engaged direct from the amp or via a dedicat-
ed footswitch. With three
incredible sounding VCM
boosters from a clean solo
boost to a smooth over-
drive, all selectable via the
utility software, the THR’s
boost function is ready
to push your tone to the
next level.
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 dum-
my load, so you can disconnect your speakers for silent
recording or on-stage perfor-
mance without having to wor-
ry about damage to your amp.
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 five
kilograms. We guarantee you’ve never come across an
amp as lightweight and compact that sounds like such
a heavyweight.
Just stomp on it
An included dedicated footswitch is available for each
model, giving you the control you need at home, in the stu-
dio 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 ca-
ble easily and
cost-effectively.

Welcome to the big time
THRC212/112
THRC212/THRC112
Stack the odds in your favor
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 character-
istics 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. The compatibility doesn’t
stop there; the THRC112 is a 1x12” cabinet that has been optimized for use with the THR100H, while the
THRC212 features two 12” speakers in a left-right configuration as is compatible with stereo inputs, so you
can take full advantage of the THR100H Dual’s unique dual amp functionality to give you the sound of two
distinctive speakers at once. Even the exterior of the enclosures has been matched to the classic design of the
THR amp heads. The THRC112 and THRC212 make it easier than ever to dial in the legendary tube sounds
you’ve always dreamed of, or cut loose with your own trademark tone that will increase your odds of winning
over any audience.

Think of THR kind of like a hand-wired amp from a tiny
boutique amp maker. It’s just not hand-wired. Or from a
tiny boutique amp maker. You see, instead of spending
their days with a soldering iron and a box full of com-
ponents, our amp developers have a slightly different
toolkit – VCM.
VCM, or Virtual Circuitry Modeling, is a proprietary
physical modeling technology developed by K’s Lab, one
of Yamaha’s most progressive engineering groups. K’s
Lab’s goal with VCM was to push digital signal process-
ing beyond the realms of simulating superficial sound
characteristics and into the muddy waters where an-
alogue equipment reigns supreme – musicality. Using
the techniques developed to make the world’s first
commercially available physical modeling synthesizer,
the VL-1, VCM uses powerful Digital Signal Processing
(DSP) technology to create virtual circuits that precisely
replicate the behavior of analog circuits and their ef-
fects on the signals passing through them – including
even the most mythical of all analog components, the
vacuum tube.
Most digital signal processors, amps and effects start
with the tone - using their DSP power to modify the
output of their audio circuit in an attempt to make it
sound a certain way. While this can create a passable
‘static’ version of the desired sound, this method misses
the things that define the best analog signal processors
– the perfect combination of response, dynamics and
tone that give analog circuits a three-dimensional feel
and, more often than not, a ‘sweet-spot’ where it just
all comes together. The theory of VCM is that by using
DSP to create a virtual circuit path for the audio to pass
through, not only will the tone be right but the VCM
circuit will also recreate those intangible elements of re-
VCM Technology Amp Model Descriptions / Specications
Why THR is different: Our sound
doesn’t start with the tone…
sponse and dynamics that combine with tone to create
the holy grail of signal processing – true musicality. By
refining the complex physical modeling algorithms that
allowed the VL-1 to generate natural tones, VCM is able
to model the precise behavior of each element in a cir-
cuit and therefore the exact changes that circuit makes
to a signal passing through it. VCM is even powerful
enough to model the tonal and dynamic changes that
result from the way a power amp interacts with a partic-
ular speaker cabinet. And this isn’t just a marketing-de-
partment invention - Google ‘damping factor’ and you’ll
start to see why the power of VCM helps make THR feel
like a big, cranked amp. Without taking it into account,
an amp just won’t feel right…
But as with most things, it’s not a case of good or bad
– just different. And that’s where the real power of VCM
comes in. While physical modeling techniques are an
impressive technical tool that can be used like a car-
bon-copy machine for circuits, we think of it more like
a virtual soldering iron in our engineer’s hands. Thanks
to the incredible power and accuracy of the VCM algo-
rithms that power THR, individual virtual components
can be changed or tweaked for each amp model based
on what sounds, feels and works better - effectively
creating modified circuits that combine elements from
different amps to make new, unique amp models that
are far more than blind, soulless simulations of other
people’s designs.
If you want to know what that really means to you, as
a player, try diming the master control on one of THR’s
low-power amp models. Sure, it has amazing tone – but
it’s the feel that you’ll notice. The tone’s really nothing
more than a bi-product. Just like any great amp.
