Step 3: Insulating the Strings - Part 2
With each string, thread one of the thin, long inserts down each string so that the flange part is further away from the guitar. This first set of inserts will go into the hole directly on the face of the guitar. It helps to rotate the saddles 90 degrees so you can access underneath them easier. It might take a bit of jiggling around, since the faceplate on the bridge might not be perfectly lined up with the holes the strings are coming through, but get the first set of the inserts flush with the faceplate of the bridge.
Next, thread the strings through the saddles. Add another thin insert to each string; this insert will rest between the saddle and the string so that the string doesn't touch that part of the bridge.
For the sake of the next step, leave the strings loose; we'll need to access the fretboard.
