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-

VCM Technology

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

CLEAN:

Rich clean tones from a 6L6 power section with early breakup for incredible jazz, blues and country sounds.

CRUNCH:
