Suzuki Soprano 25 - 1970s - tuning

This is the 1970s Soprano 25 (S-25) Melodion. It is the Soprano counterpart to the 1972-85 A-25, the Study 25. Shown are photos of the model and then of cleaning and tuning, our first foray into tuning with an electric engraver, the Wen 21C Variable Speed Engraver.
