Marshall Amplification Valvestate 2000 AVT User Manual

ENGLISH
From Jim Marshall
I would like to thank you personally for selecting one of our
Valvestate 2000 AVT amplifiers.
After its initial launch, the original Marshall Valvestate technology
received worldwide acclaim and set a new standard in affordable
quality amplification. However, my team of designers are constantly
looking for methods to make our amplifiers sound even better. As
they are all guitar players themselves this process has become a
passion within the design department.
As the name Advanced Valvestate Technology suggests, your
new amplifier benefits from their research and utilises the latest
circuitry, which is absolutely unique to Marshall. By emulating the
feel and response of an all-valve amplifier even more closely, the
new AVT range perform brilliantly and represent another major step
forward in guitar sound technology.
Since I first began making amplifiers in 1962, one of the key factors
in our success has been reliability. Therefore, many hours of
exhaustive testing have been carried out in the development of AVT
to ensure that this remains so.
I suggest that you read this manual thoroughly before operating
your new amplifier and keep it in a safe place for future reference.
This will help you to derive maximum enjoyment from our Advanced
Valvestate Technology.
Wishing you every success.
Yours Sincerely,
