The Rickenbacker Electro A-22, nicknamed the "Frying Pan" is the first electric lap steel guitar. Developed in 1931/1932, it received its patent in August 1937. A previous attempt, the Stromberg company‘s transducer-based "Stromberg Electro", was introduced in 1928. It used a "vibration-transfer rod" from the instrument's sounding board attached to magnets inside the guitar, and was not successful. George Beauchamp created the "Fry-Pan" in 1931, and it was subsequently manufactured by Rickenbacker Electro. The instrument gained its nickname because its circular body and long neck make it resemble a frying pan.
