Intonated Saddles

Could you explain the different types of saddles and the effect on intonation?  Some are straight and some are slanted.  TAYLOR uses a compensation for the B, LOWDEN uses a split bridge that looks like it's just compensating for the B?  I have a steel string guitar with just a slanted one piece saddle and it has real problems with the B string.  I also have a nylon string or classical guitar and it doesn't seem to have the same problems.

Thanks for any explanation.  Robert Jacob

Sometimes it is possible to use only ONE piece of bone, etc. for a saddle. To the right is an example of this.  The luthier or manufacturer will file away or mold a piece to make the string length right. If the piece is placed right and filed/molded right, only one piece is needed to get fairly good intonation.  If you look carefully under the second string from the right (B String) there is a slight bevel under there.  You should see the intonated saddle on my 12 string.  It's looks like a sidewinder snake under the strings. Two or three pieces may be used depending on personal taste and it gives the luthier more area to work with. Nylon string guitars don't need this as much because the strings are all pretty much the same diameter. That's why the saddles aren't slanted.  To the right is an example of this. Bob, Gman ( o )==#
