Editing Marshall Amplification (section)

===Solid-state amplifiers===

Marshall's "Valvestate" amplifiers contained a hybrid of valve and solid-state technology. Currently named the "AVT series" (although these are now out of production, being replaced with the "AVT tribute" for a short time), there are a number of different models, all of which are less expensive than their all-valve counterparts. It is Marshall's current line of "hybrid" amplifier, featuring a 12AX7 preamplifier valve employed in the preamplifier (to "warm up" the signal) as well as solid-state components, with a solid-state power amplifier. These are considered and marketed as intermediate-level equipment to bridge the gap between the higher valve range and lower range MG series.

In January 2009, Marshall released their latest variant of the MG line of practice amplifiers. Replacing the MG3 line, the MG4 has been designed to offer the guitarist a whole host of features whilst keeping the control of the amplifier simple.
