What is AVT?
    Advanced Valvestate Technology, or AVT for short, is a major step forward in hybrid amplifier design which is exclusive to our new Valvestate 2000 (VS2000) Series of amplifiers. It has evolved from the original, critically acclaimed Marshall Valvestate technology, but is improved so that it emulates even more closely the feel and response of the classic Marshall all-valve power stage...without using valves.
    It is not only the power stage that has been significantly improved in the VS2000 Series either. Much careful attention to detail and many hours of development have also gone into the preamp section too. As a result, each AVT channel offers the widest possible range of control and shape to your sound, with an ECC83 (a.k.a.12AX7) preamp valve adding to the all-important tone and feel of these latest Marshall creations.

Valve Drive Preamp
    As just stated, each amp in the VS2000 range boasts a preamp stage equipped with an ECC83 Dual Triode valve. Drawing on our vast experience in this field, we have gone to great lengths to ensure that this precious device delivers maximum sonic benefit at all settings and volume levels. As a result, the clean sounds ring with the ‘bell-like’ harmonics that only a valve preamp can deliver and the break-up is never harsh or unnatural sounding. Whenever an AVT Overdrive channel is selected the ECC83’s dual triode is saturated to its limit, providing the dynamics and feel worthy of a place in the Marshall hall of fame.

Power Amp Delivery
    The same sort of toneful care and attention was also focused on the all-important power stages of the AVT series too. Our goal was to ensure that each one would create the warm, musical feel and 3-dimensional sounds that have made our all-valve power amps world renowned. In addition, these VS2000 products were designed to deliver the goods in the often hostile and unpredictable environment of the live performance stage - which is why all the AVT power amps, from the AVT50 upwards, are fan cooled for optimum reliability.

'Extended Bass Response' Loudspeakers
    Knowing how important the relationship between the amplifier and speaker is, this is another area where we spent a great deal of time and effort when developing the VS2000 Series. By working extremely closely with our long-term colleagues at Celestion Loudspeakers, we have successfully developed a range of speakers which, through radical design, re-define the state-of-theart in rock guitar reproduction. In a nutshell, they allow the compact closed back cabinets used in the AVT range, to maintain the bottom end delivery normally only associated with a full 4 x12 cabinet setup.

DFX Onboard
    At Marshall our aim is to create products that offer our fellow guitarists true inspiration in the practice and performance of their art. When integrating DFX (Digital Effects) into the tonal topology of AVT, the greatest care was taken to ensure that the highest level of signal integrity was maintained. Through careful shaping and mixing of the ‘wet’ (processed) and ‘dry’ (unprocessed) signals, we have ensured that the onboard effects enhance your tone while adding none of the nasty, artificial ‘grain’ often associated with DFX. Different effect types can be assigned to the Clean and Overdrive channels and can, of course, be turned on and off via the sturdy 6-way LED foot controller supplied with your amp.
    We are so proud and enthused by the end results of our labour that we feel fully justified in hailing Advanced Valvestate Technology as a major breakthrough in hybrid guitar amplifier design. We are convinced that you will derive as much pleasure from playing them as we did while designing them. Enjoy!
