The Sunrise Guitar story starts with Patrick Murphy, who received training as a luthier while stationed in Germany and also worked with classical guitar maker Rainer Krempel. In 1971, he opened the Instrument Repair Shop (IRS) in “the back closet room” of the Sound Factory (later ProCo Sound, Inc.) on East Kalamazoo Avenue. In his words,
“Originally, I did no work on electronics, as I wasn’t too impressed by them. I was a true-blue acoustic person. Later, I figured out that if I wanted the shop to remain viable, I had to expand to electronics.”
