the tuning button. Your gears should turn smoothly now, and last for
the life of your guitar.
Generally there are only 2 parts you’ll have to replace tuner-wise,
those being the tuner button, or the entire tuner assembly.
Replacing the tuner button is simple, all you have to do is take out
the screw that holds the tuner button in place and the button will
slide off its post. Simply slide the new one on and put the screw back
in place and you’re done.
Before you can replace your tuners you’ll have to get a new set, this
can be a somewhat overwhelming process as there and many
different types and sizes of tuners on the market. The simplest way
to make sure everything will work correctly is just to buy the exact
same tuners that were on the guitar already.
If you are looking to upgrade however, you will have to take a few
measurements to ensure proper fit of the new tuners. Measurements
needed are: thickness of the headstock, height of the string post,
and size of the hole that the string post sits in. You will also need to
decide on a gear ratio. Most tuners have a 14:1 gear ratio, but there
are units available from the regular 14:1 to 25:1 for extreme fine
tuning, but overboard unless you’re a serious guitarist.
Once you have decided on a tuner set, replacing the tuner is simple,
just unscrew the nut on top of the headstock and slide the tuner out
through the back. Reverse the process for the new one and you’re
done. Be sure to double check that the new tuners are set tight on
the headstock.
