Amplifier-equipped electric guitar. Sound is produced by inserting a 9V square battery and flipping the pig-nose switch. It's in nearly new condition, except for a scratch on the bottom of the body. The frets also seem to have about 90% life remaining. I've checked the built-in speaker, external output jack, and headphone jack, and they all function normally without any crackling. I applied lemon oil to the frets as they were dry, and adjusted the string height. There's no fret buzz or dead notes. Neck is straight.
