Fender's Acoustasonic 90 Combo acoustic guitar amplifier has all the features you need to get through any acoustic gig in style. The Acoustasonic 90 Combo is perfect for singer/songwriters too, thanks to its separate microphone and instrument inputs. You can plug in both your instrument and a microphone, for an instant solo PA. Or, plug instruments into both channels. You get great-sounding effects, and a balanced line out for more flexibility. Feeback-elimination controls keep the 90-watt Acoustasonic 90 sounding great even at higher levels.
