Marshall AS100D acoustic guitar combo amplifiers are specially designed for use with a variety of acoustic instruments, regardless of whether they have pick-ups built in or not. Marshall AS100D comes loaded with four channels, delivering the flexibility to handle instruments with piezo transducers or magnetic pick-ups, plus microphones, for both vocal and acoustic instrument reproduction. The two main acoustic instrument channels on AS100D [1 and 2] may be linked together and feature independent level and EQ controls.
AS100-D also features a dedicated microphone channel that offers a similar level of control. Marshall AS100D also has phono inputs on the Auxiliary channel, specifically for use with external audio equipment.
