1 rocknroll 10 months ago I have a filing cabinet FULL of old Grover, Kluson & Waverly tuners which have been in storage for 30+ years from a music shop which closed in 1980. Most of these tuners date from 1930 through 1970. Some complete sets and some singles. Email me if you are looking for any specific tuners.Here are three 1950's era chrome plated Grover Imperial tuners all for the bass side. These pre-date the USA stamp on later Imperials. All tuners are in excellent cosmetic & functional condition. Note diameter of the string post in the picture.Selling these tuners for $40 each plus shipping. Email me for quickest response.
