EDWARDS EBA 10 guitar and bass amplifier. I have confirmed that it powers on and produces sound when connected to a guitar. However, the LOW knob doesn't work, so it's being sold as a defective/junk item. It might be an easy fix for someone knowledgeable, but I don't have the expertise to repair it! It's compact, making it ideal for home practice. - Model Name: EBA 10 - VOLUME.HIGH.MID.LOW.PRESECE - Country of Manufacture: Korea There are no noticeable scratches or stains, but there are minor scratches and light dirt. Please check the images carefully as this is a used item before purchasing. It will be packed and shipped in a recycled cardboard box.
