The Sperzel Trim-Lok Locking Tuning Keys have graduated heights (no string trees needed). Cast gear housings with sealed lubrication. Single pin mount keeps tuner from rotating, no mounting screws needed. Recommended for 1/2" - 9/16" (12.7mm - 14.29mm) thick pegheads.
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.
