Hint: it’s better to drill a slightly deeper hole rather than a slightly shallower hole. Use one of the bridge posts to estimate the depth and place masking tape to identify the depth. Before starting to drill any holes, determine the depth of the holes. NOTE: the line draw on the body is not the scale length but rather it marks the position of the bridge posts. Mark the positions of the posts (lines and circles bolded in Photoshop) Close up view of post positions You can do this by rotating the bridge by 3 degrees around the treble post (see the green line in next figure).

In that case, it is common practice to shift the bass-end of the bridge a few mm away from the pickups. On some bridge models, there may not be enough “saddle-room” for correct intonation at the bass-end of the bridge. Identification of the exact location of the saddles according to scale length Once the bridge is aligned for scale length and between the fingerboard lines, then mark the locations of the bridge posts using a pencil. The bridge must now be aligned between the two fretboard lines you can easily do this by eye, use a ruler or better yet, place a string along the treble E and bass E paths and align the bridge that way. Before placing the bridge under the ruler and in order to allow for intonation compensation (later during tuning), bring all the saddles at their most forward positions (as shown in the image below) and align them under the ruler.

The exact position of the bridge saddles can now be located. Place a ruler on the fretboardĪ scale length of 25″ means that the 12th fret will be at 12.5″ from the nut and 12.5″ from the bridge, meaning the half-way point. The scale length on this guitar is 25″, so the 25″ mark is placed at the location of the strings over the eventual nut. Place a long ruler on the fretboard and align it with the center line. By knowing the scale length, you can now calculate the exact location of the bridge saddles. The two lines extending from the fingerboard (lines were bolded in Photoshop) If your guitar body is sanded to receive its finish, then I suggest placing making tape on the body and drawing the lines on the tape.) Draw two lines that extend from the fingerboard (line was made bolder in Photoshop) (Note that in this case the body has not been finish-sanded yet so I’m not worried about pencil marks. The two lines will *not* be exactly parallel to each other since the fretboard is tapered (narrower at the nut and wider at the body). You should end up with two lines that are extensions of the fingerboard (see image). Step 1: Alignment. Place a long ruler along the side of the fingerboard and extend the ruler onto the guitar body. Since the strings vibrate between the nut and the bridge (the scale length) and since the position of the nut is fixed, the exact position of the bridge will determine the correct scale length. The position of the bridge on the body is highly dependent on the fretboard and the nut.

Important: Before starting to install the tune-o-matic bridge posts (or bushings) make sure the neck and fretboard are in their final positions.
