Why THR is different: Our sound
doesn't start with the tone...
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-

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.
Amp Model Descriptions / Specifications
Amp model descriptions
