Why guitar bridge angle

The stiffness of a string keeps the ends of a string from vibrating efficiently, resulting in a "speaking length" that's shorter than the actual string length. An angled bridge or adjustable saddle pieces gets you closer to matching the speaking lengths of all the strings.

Why are tune o matic bridge angle?

Many guitar designs with fixed bridges have the bridge slanted or stepped so that the distance from nut to bridge is larger for thick strings. The Tune-o-matic extends this idea to make the distance adjustable for all the strings, within limits.

Which side of the guitar bridge should be higher?

I believe that the bass side of the saddle is always higher than the treble, to accomodate the larger vibration amplitudes of the wound strings. So, yes, it should be the other way around with the high side under the low E. If your saddle is compensated, you can even see a notch that holds the B string.

Why are guitar saddles shaped?

It is designed to provide the most accurate intonation and ensure the guitar is in tune along the fretboard and produce the correctly pitched note. This type of saddle will have a raised end or grooves (usually for the B string) that provide the best intonation for the best tone and accurate pitch.
