circuit Modeling System ), the stunning realism of which has deservedly earned an ava-
lanche of critical acclaim and has been welcomed with open arms by serious guitarists all
over the globe.
The result of this perfect marriage is a digital modeling amp that sounds, feels,
looks and operates like a guitar amp...what an amazing concept! It isn’t merely a multi-
effects device hooked up to a stiff sounding, solid-state power amp driving some ho-hum
speakers that can’t cut through a band, even when turned up to “11”! And it isn’t a guitar
amp stuffed with some hurriedly built, “catch-up” digital stuff either. No sir, Valvetronix is
the real deal - the best of both worlds.

n keeping with Vox’s brave, pioneering spirit, the Valve Reactor circuitry that drives the
power amp in your new VOX combo is a groundbreaking piece of technology. Without
getting overly technical, here’s what’s going on...
While much of the tone creation and shaping carried out in this amp is done in the
digital domain, its Valve Reactor power amp is 100% analogue. The resulting journey
your guitar’s signal takes through the analogue world of the power stage plays a major
role in providing the all-important feel and tone of the original amps we modeled.
The Valve Reactor power stage is, to all intents and purposes, a bona fide valve
(tube) push-pull power amplifier, but in miniature. It utilizes a 12AX7 valve (a dual triode
device - meaning “two valves in one”) and is equipped with an output transformer, just
like a “real” valve amp. Instead of connecting directly to the loudspeaker though this
transformer is connected to a specially designed
VariAmp Power Circuit that increases
the magnitude of the transformer output from its lowest level (1 Watt) up to the maximum
output of 60 Watts per channel.
Because VariAmp Power Circuit stage is completely transparent (doesn’t colour or
change the signal in any way), the resulting output tone is pure valve. It also ensures that
the output signal maintains the high dynamic range associated with traditional valve
amps - something most solid-state amplifiers cannot deliver, and one of the main factors
why valve guitar amps normally sound and feel so much louder and more alive than a
solid-state amp boasting the same output power.
What is ?
(Resonant structure and Electronic circuit Modeling System) is KORG’s propri-
etary sound modeling technology which precisely reproduces the complex character
and nature of both acoustic and electric instruments as well as electronic circuits in
real world environments.
emulates a wide variety of sound generation charac-
teristics including instrument bodies, speakers & cabinets, acoustic fields, micro-
phones, vacuum tubes, transistors, etc.
