countries just mentioned, in honour of their heritage, the descriptions of all
English amps will employ the words "valve" and "valves," while the American
ones will be tubular!
QUESTION: What's the difference between an ECC83 preamp valve and a
12AX7 preamp tube?
ANSWER: Nothing! They're the same exact thing — namely the most popu-
lar preamp tube in ampland. ECC83 is the British name, 12AX7 (a.k.a. 7025)
is the American.
Power Amp Accuracy
What happens in the power stage of any good tube amp is of paramount impor-
tance to the way the amp sounds, feels and behaves. The way the power amp
operates (Class A or Class AB), the power tubes used (EL84s, EL34s, 6L6s, 6V6s),
the exact nature of the negative feedback loop circuitry (if one even exists) and
how the power stage interacts (a relationship called damping) with the
speaker(s) it is driving – all these things play a vital role in the creation of tone.
That is why we have fitted your SV-1 with our patented Valve Reactor Technol-
ogy – a modelling breakthrough that is unique to VOX (a member of the KORG
family) and infuses our critically acclaimed Valvetronix range of amps with life
and feel. This revolutionary technology emulates a tube power-amp by using real
tubes in a real tube amp circuit and ensures that all the important bases inherent
in a tube amp are faithfully and accurately covered. For example: if you choose
amp model AC30 – an amp with a Class A power stage, EL84 output tubes and
no negative feedback, that's exactly what your Valve Reactor power amp recon-
figures itself to be.
This all said, let's take a look at each of our amp models...
