Tying The Classical 3 Hole Bridge
The 3 hole bridge can be tied using only the center hole in the normal fashion as done with a 1 hole bridge. Or, you can use all 3 holes, which I prefer. The 3 hole tie places more downward pressure on the saddle. The 3 hole method is shown below.

Start by pushing the string through the center hole from the front of the bridge. Push about 2cm of length through the hole. Experience will show you how much you need to push through.

Looking from the back of the bridge, push the string end back through the right hand hole.

Then push the string end again back through the left hand hole.

When the string end comes out the back of the bridge again, put it through the loop that was created in photo number 3 above.

Finally, pull the string tight from the front and attach it to the tuner. This whole operation takes very little time.
