However, my dedicated 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 (AVT) suggests, your new amplifier benefits from their research and utilises their latest circuit innovations, all of which are totally 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 yet another major step forward in guitar sound technology. 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, 1 ENGLISH 3 .
