Difficulty: Moderately Challenging
Step1
Find a guitar with a bent neck. You can get a used one cheaply since a guitar like this is no longer good for regular playing.
Step2
Loosen the strings by turning the tuners counter clockwise. You are loosening the strings to allow the nut to be removed.
Step3
Remove the nut. You should be able to do this with a little tugging, or you may need a screwdriver or something to pry it out if the neck is very bent.
Step4
Replace the nut with a new one that sits higher and straight across. This makes the strings sit higher and causes the sliding to sound more powerful.
Step5
Tighten the strings again by turning the tuners clockwise once the new nut is in place. Tune the guitar again.
Step6
Replace the bridge for an even better sound. This raises the strings even more. Remove all of the strings. On some acoustic guitars, the bridge may be adjustable like they are on electric guitars.
Step7
Find something to slide. Almost anything hard can be used, so find something that works well for you and fits in your hand well. You may use a bottle, a tuning fork or anything. Use it in your first 2 fingers while playing.
