Gotoh Staggered-Height 6-In-Line Tuners
Eliminates string trees for better tuning.
With different string post heights, each string gets ideal downward tension behind the nut. No need for string tree hold-downs or their interference with vibratos.
Vintage-style stamped gear housings, oval metal knobs and smooth, precise operation.
 
 
15:1 gear ratio
11/32" (8.73mm)-diameter pegholes required
Maximum peghead thickness 9/16" (14.29mm)
Set of 6 includes mounting screws and knurled press-fit bushings.
 
This is what I put on my custom guitars. They are a drop in replacement set for vintage style tuners. They're smooth and solid.
