Rickenbacker also began making semi-acoustic guitars in 1958. When the company changed ownership in 1954, they hired German guitar crafter, Roger Rossmiesl. He developed the 330 series for Rickenbacker, which was a wide semi-acoustic that did not use a traditional f hole. Rather it used a sleeker dash hole on one side of the guitar, the other side had a large
pickguard. This model boasted a modern design with a unique Fireglo finish. It quickly became one of Rickenbacker's most popular series and became a strong competitor to Gibson's models.
