NOPE -- not this model--
from the manual -- its BI-POLAR
INNOVATION IN AMPLIFIER TECHNOLOGY Marshalls' Valvestate is a revolutionary concept in amplification. Using the most up to date techniques our designers have produced a truly outstanding range of products for every level of guitarist. From the 10 Watt practice combo to the 100 Watt stack and now with our latest additions the 80 Watt per side Bi-Chorus combo and 100 Watt per side Bi-Chorus head, Valvestate technology will give you a quality of sound that is in every sense true Marshall. Valvestate is able to do this by simulating the performance of a valve power stage. Using Bi-Polar devices in models 8010, 8020, 8040, 8080, 8100 and 8240 and MOSFET devices in models 8280 and 8200 in a new constant current configuration produces the type of high impedance output levels normally only delivered by a valve amplifier. This creates speaker reaction similar to that found in valve equipment. Ringing harmonics, rich bass response and sensitivity give Valvestate amps that special Marshall ''feel" which is a joy to play! To achieve the full dynamic potential of Valvestate power, we designed pre-amp sections of incredible versatility, with masses of gain and the widest tone control possibilities. Models 8040, 8080, 8100, 8240, 8280 and 8200 feature a Marshall ECC 83/12 AX7 valve in the pre-amp to give even greater dynamics by providing real valve overdrive. In addition, our special "Contour" control lets you focus the overdrive from mellow blues, right through to all out screaming metal. Also the totally analogue stereo chorus and reverb effects on the 8240, 8280 and 8200 help create some of the biggest sounds imaginable. Whatever your style of guitar playing, Marshall Valvestate will give you the edge! This handbook covers the Valvestate guitar amp and combo range and has been compiled to help you to get the best from your amplifier. There is no substitute for playing experience and due to the great versatility of this range you should experiment as much as possible in order to familiarise yourself with the controls. The Marshall Valvestate range has been designed by our amplifier engineers to add new dimensions to your guitar sound. The controls are there to be used to the full, so be extreme and enjoy getting to know Valvestate.
