Marshall's AVTX line of amplifiers is the culmination of a decade's worth of evolution and innovation since the birth of the original Valvestate. All models now feature a new contemporary look and all AVT50X, AVT100X, and AVT150X models include automatic variable speed fans, ensuring their place as the market leader.
Both the AVT150X and AVT150HX boast more channels and features than any Valvestate amplifier before. Their four channels are: Acoustic Simulator, Clean, Overdrive 1, and Overdrive 2.
Acoustic Simulator: As its name suggests, the Acoustic Simulator channel transforms the sound of a standard electric guitar into that of an acoustic guitar with amazing authenticity.
Referring to a Guitarist magazine review: "The Acoustic Simulator is a brilliant idea -- a first for a non-digital amp -- and the tonal effect is extremely convincing with single coil pickups, allowing a guitarist to switch instantly from electric to acoustic sounds without changing guitars or amps."
For even further flexibility, the AVT150X and AVT150HX house a pair of adjustable DFX sections -- one for the Acoustic/Clean channels and the other for Overdrive1/Overdrive 2. Both DFX sections are on/off foot-switchable via the supplied 6-way LED foot controller.
Clean: From the cleanest clean to a natural, valve-induced, bluesy crunch and anywhere in-between. A Bright switch enhances high-end definition at low Gain settings.
Overdrive 1: Takes you from the dynamic raunch of a 1959 'Plexi' to the larger-than-life crunch of a cranked JCM800. A Scoop switch reconfigures the EQ to give you that classic thrash sound of the '80s.
Overdrive 2: From the primal angst of a hot-rodded JCM800 to extreme gain. Hit the Scoop switch to produce the brutal, bone-crushing slam of modern ('nu') metal.
The 16 DFX are adjusted by the following controls: DFX Mix, DFX Adjust, and DFX Select. A Parallel FX Loop, complete with Mix control, is also included for added flexibility. The supplied 4-way LED foot controller allows you to switch the DFX on/off. Other features include a Headphone jack and a Speaker Emulated Line Out.
