Pegs for [[double bass]] and [[guitar]] family instruments are usually geared, and are called tuning machines or [[machine head]]s. They often use a [[worm gear]]. The [[gearing ratio]] varies; while higher ratios are more sensitive, they are also more difficult to manufacture precisely. Machine heads may be open, with exposed gears, or closed, with a casing around all the gears.
Line 87:
The most recently marketed pegs of this sort use [[planetary gears]] designed to fit inside a case shaped like a friction peg, and have seen some adoption as they require no more modification of the instrument than a new set of friction pegs and make fine tuners unnecessary.
