Sperzel's rear thumbscrew locks the string, making these machines ideal for tremolo guitars. The string posts on 6-in-line sets have graduated height (no string trees needed). Cast gear housings with sealed lubrication. Single pin mount keeps tuner from rotating, no mounting screws needed. Recommended for 9/16" - 11/16" thick pegheads.
• 12:1 ratio • 10mm (13/32") diameter pegholes required • Removable metal knobs • Threaded peghead bushings included • Sets of 6
Staggered string posts: The Sperzel 6-in-line tuners feature 3 heights of string posts in each set. The tallest two tuners are used on the E and A strings, the medium length posts are used on the D and G strings, and the shortest two posts are for the B and E strings. This allows the E, B, G, and D strings to have a steeper angle off the nut than with traditional tuners — eliminating the need for string trees.
To be sure these tuners fit your instrument, compare your existing machines and peghole dimensions to our listed specs to help determine the best replacement.
