Amplifier-equipped electric guitar. Sound comes from the speaker using a 9V square dry cell battery. I have confirmed that sound comes out normally from the built-in speaker and the external output jack. The neck is straight. Fret life is about 80% remaining. No scratchy noise or buzzing. Almost no scratches, it's clean. Speaker ring is self-made. Strings replaced after cleaning. Comes with a soft case. Spare 1st string (which breaks easily) and picks included. Will be shipped in bubble wrap and cardboard packaging.
