Michael Diehl opened a small store in Freehold, New Jersey after serving in the United States Navy during World War II. He attended college on the GI Bill and found that he could run the music store with a small loan from the bank. His business flourished during the great accordion craze of the late 1940s and 50s. He was one of the very first Fender Guitar dealers in the country and watched as the electric guitar became even more successful than the accordion, a fact that shocked Mike. Over the years the store grew in sales and size based on one fact, according to Mike, customer service!
