Review: Excellent unit. We use it in the downtown streets of Vancouver to proclaim the gospel as found in the Bible. Faith in the Lord Jesus Christ, in him alone not of our works but it in his finished work on the cross. Repent and turn to him for the free gift of salvation. Maranatha.
Review: This amplifier is amazing. I do a lot of campfire singing and this allows my acoustic guitar to be amplified as well as the mike. When you are outside your voice and instrument are sometimes lost but with this amplification the sound carries much farther. Great little box.
