Although this model was never really produced by Sho-Bud, it is mentioned here because several prototype Keyless pedal steels (Single-10) were made. The Keyless was built to eliminate the raise and lower changer mechanism by using permanent changer fingers at both ends of the guitar. One end to raise and the other end to lower. The Keyless guitar idea never caught on with Sho-Bud and the idea was dropped. Had Sho-Bud continued with the development of the Keyless, they would have no doubt, been successful. Today, many pedal steel manufactures offer keyless models that play and sound great.
