The Marshall AVT100 100W 1x12 3-Channel Combo Amp with DFX is a 100W, 3-channel 1x12" combo with digital effects. 3 tube preamp channels are voiced to give the broadest tonal range possible, from clear, crystal clean to valve-induced crunch and on to the most extreme gain ever found in a Marshall. This third channel also features a scoop switch that you flip to get bone-crushing crunch. 16 custom-voiced digital effects are selected and adjusted by 3 simple knobs: Mix, Adjust, and Select. In addition, a supplied 4-way LED footswitch lets you move seamlessly between channels and switch effects off and on. Other features include a headphone jack, speaker-emulated line out, plus an effects loop with level and front panel mix control. Like all the AVTs, its preamp section is based on a 12AX7 and delivers great tone.
