1-5/8" WIDE x 3/1/2' LONG (at top of bridge)

DISTANCE FROM TOP SCREW HOLE TO BOTTOM SCREW HOLE = 1-3/4"
DISTANCE BETWEEN STRINGS = 7/8"
DISTANCE FROM HIGH E TO LOW E = 2-1/8'

This intonatable bridge has individual saddles.
Each saddle has two screws, one for height adjustment and one which locks 
the saddle in place and allows the saddle to be positioned for correct intonation.
It also seems to help sustain and resonance if you screw the central fixing screw
hard down so the back of the bridge sits on the top of the body.

Installation:
Two flathead screws (not included) go under the top of the bridge not through the
bridge holes. Roundhead screw (not included) goes through bridge hole on the bottom.
Screw in the two flathead top screws so that the underside of the bridge is a
minimum of 1/16 inch distance away from the body of the guitar. Start bottom side
adjustment of bridge so that you can slide a medium thickness pick
between the bridge and the body. Fine tune your installation adjustments. 

Adjusting the bridge:
The locking screw sits directly under the string so to stop the saddle
shooting forward you need to slacken the string before you unlock it.
It also seems to help sustain and resonance if you screw the central fixing
screw hard down so the back of the bridge sits on the top of the body.
