Introduction

Congratulations for choosing the 2/50 Head. It gives us great pleasure to welcome
you as a member of The Valve family. We will be delighted to thank you for placing
your trust in us by providing you with reliable, always-available support to allow you
to really tap the potential of this extraordinary amp head.

One of the major challenges faced by any maker of musical instruments is how to
allow musicians to reproduce the precise sound they have in mind. As a guitarist, you
should always - whether in the studio or on stage - be in a position to reproduce your
personal sounds, the ones that you've been working hard to refine and develop in
your head. As musicians and amp makers, our mission is simple: to provide you with
products that, once the gig is under way, you will never have to turn away from the
audience to adjust.

Amplifiers from The Valve are designed to provide you with the map to your sound.
The front and rear panels display tonal capacity only. By reading this instruction
manual you will discover how, with just a little bit of maintenance and care, this amp
will give you great enjoyment for many years to come.

The lightning flash with an arrowhead symbol within a triangle is intended to
alert you about the presence of an un-insulated "dangerous voltages" within
the product's enclosure that may be of sufficient magnitude to constitute a
risk of electric shock to users.
