I just know the standard measurement between rollers are 35mm on many machine head tuners. But what are the differences with various gear ratios, there are 1:14,1:16,1:18.... Are they also as important as getting the right measurement between rollers?
If my guitar has a 1:14 gear ratio, can I change to 1:16 or 1:18?Do they fit well (the rollers are 35mm anyway)?
