    Can anyone explain the ratio of different tuning machines out there? I keep seeing 23:1, 20:1, 18:1...etc. and I am wondering what the ratio's mean in layman's trms so I know which to look for to stay in tune more than the others.

    I believe it's how many full turns of the key it takes to make the tuning peg revolve a complete 360 degrees.

    20:1 - twenty turns of the key to the one revolution of the post.

    It is a gear ratio, same as with bike gears. Like Brendan said, 20:1 means 20 turns of the key for one of the post.

    The higher the better, it allows more precise tuning.
