These bridges have individual saddle pieces like the Fender and Gibson style bridges, but the Floyd Rose bridge saddle pieces are not adjustable and cannot be filed down. The Floyd Rose saddle pieces are hinged to intonation pieces that are bolted to the bridge itself. The intonation pieces are the parts of a Floyd Rose bridge that actually set the radius of the strings. The radius on a Floyd Rose bridge rarely needs to be set. If you have measured the fretboard and strings radius and they are not the same, the Floyd Rose Bridge will have to be adjusted.
Remove the Strings
To adjust the string radius on Floyd Rose Bridge, you will have to take the stings off of the guitar and out of the saddles. Unbolt the locking nut and de-tune the guitar. You may notice that once you de-tune the guitar the bridge’s tail end will start sinking and eventually bury itself in the body. You can eliminate this problem by pushing down on the whammy bar and placing a block of wood underneath the Floyd Rose Bridge. The block of wood will stop the bridge from being pulled back by the spring tension while you de-tune your guitar. See the previous article on how to restring Floyd Rose Guitars.
Unbolt the Intonation Piece
Next, unbolt the intonation piece from the base of the bridge. Now, the entire saddle and intonation piece can be removed from the bridge. You will need to clamp the piece down either in a vise or clamp in order to file it.
File the Intonation Piece
Next, file the bottom of the intonation piece to lower the string height. Start with the D and G-strings. Once you have leveled those, bolt the intonation pieces back in the bridge, restring it, and measure the strings to make sure both the D and G-strings are equal in height. Repeat these steps with the A and B strings and then with the high and low E strings.
A word of caution: This repair can be time consuming because you have to keep disassembling the bridge, reassembling it, restringing it, and measuring it. Make sure to file small amount of material off of the bottom of the intonation pieces at a time. You do not want to make a mistake and take too much material off the bottom of one of the intonation pieces and have to start over adjusting the D and G-strings. Take your time.
If this repair needs to be done, it is kind of a pain. You don’t want to get half way through it and be forced to start over because you took too much material off the bottom of one of the intonation pieces. But as I stated in the beginning of this section, Floyd Rose bridges rarely need the string radius adjusted if ever needed at all. There will be more to follow up on the Floyd. Until next time!
