They have a gear ratio of approximately 12-1. Two are marked "B" for the bass side, one is marked "T" for the treble side and one is not marked with the "T" designation however it has the same rotation as the other treble side tuner. Please view the pictures for the best description. Only the parts shown are included. I can add more pictures from any angle if you can't view these clearly.
