FROM THE CHAIRMAN

I would like to thank you personally for selecting one of our
Valvestate

!

amplifiers.

For many years, the name Marshall has been amongst the
leaders in the field of guitar amplification. This has been
achieved by a combination of many things, particularly our
ability to listen to musicians and produce the sounds that
they want, plus a constant drive for quality and reliability.
In order to retain our leading position, our design team work
tirelessly to achieve innovation in guitar amp technology. 

This resulted in the Valvestate

!

range which was

launched over the early 1990's. With this radical
development they succeeded in producing something really
new for the guitarist. Their latest development takes this
range one step forward by adding the 8200 and 8280 Bi-
Chorus models to the already successful Valvestate

!

line.

I suggest that you read this handbook carefully in order to
fully understand the many sounds and functions contained
within your Valvestate

!

amplifier.

All our equipment is built to withstand the test of time and
our new Valvestate

!

models are no exception. You can

rest assured that on the subject of quality, Marshall never
compromise! 

I would like to wish you every success with your new
amplifier and ask you above all, to enjoy your Marshall.

Sincerely
