 Hi, I'm Emily Tillman and this is Did You Know Mississippi. Did you know that one of the world's largest manufacturer and suppliers of musical and professional audio equipment is headquartered right here in Mississippi? Hartley Peavy was born on December 30, 1941, in Meridian, Mississippi. His father owned a music store and gave him an old electric guitar, but he needed an amp. His dad told him, when you learn to play, then I'll think about it. So instead of waiting, he built a huge amp out of surplus parts.
