The Floyd Rose Tremolo is a specialized bridge that is installed on electric guitars. What's distinctive about this bridge is that it renders the tuning pegs on the head of the guitar useless and instead uses tuning tabs directly on the device. So if you've recently bought a Floyd Rose Tremolo and are a little confused as to how to go about putting it on your guitar, you'll be pleased to know that installing it is a relatively straightforward process.
Remove the strings from your guitar by twisting the tuning pegs at the head of the guitar until they are loose enough to be removed.
Use the tip of your screwdriver to pop the small rectangular nut off of the guitar at the point where the head meets the neck of the instrument.
Pass your electric router (available at hardware stores) over the area where the nut rests. Do this several times until the area is worn down about a quarter inch.
Fit the new Floyd Rose Tremolo nut in the old one's place and press it down, so it is secure.
Use your Phillips screwdriver to remove the old bridge from the main body of the device. This is where the strings originally connected to.
Replace with the Floyd Rose Tremolo and tighten the screws. Run the guitar strings through the holes on the bridge and then run them up the fretboard and connect them at the top latches on the nut.
