So now you know the secret to the AVT series: the perfect marriage of tube tone and solid state reliability. Especially when you overdrive that valve to bring out the warm overdrive and singing distortion that only tubes can provide. Of course, that high voltage 12AX7 (ECC83) tube in the preamp section gets half the credit, too. They have nailed the classic Marshall tube power amp sound, but without the heat and expense of power output tubes! The secret to the amazing sound of the AVT line is a brilliantly engineered power amp section that emulates the way tube amps breathe and musically compress the sound. The good news for guitarists the world over: these amps sound awesome! Now Marshall engineers have concluded two years of researching and refining the techniques of tube and solid state amplifier sound properties in order produce the finest combination ever heard. These relatively low-priced amplifiers rapidly captured the ears and hearts of musicians worldwide.

Marshall introduced its original Valvestate line in the early 1990's. At the heart of the AVT is a genuine 12AX7 (ECC83) tube that is driven at a high plate voltage to add the genuine, warm tube tone that guitarists crave. Marshall AVT150H 150W 4-Channel Head with DFXĪVT (Advanced Valvestate Technology) is the latest in Marshall's research to develop a tube/solid state hybrid amplifier that nails the sound of their classic, all-valve amplifiers.
