Intonation compensation is a common set up procedure.
However, different bridges can require different treatment.
Electrics:some bridges like the classic fender or the Gibson "tune o' matic" can be easily worked since the saddles sits on movable screws.
even Floyd rose bridges have Allen screws.
acoustic/classic bridges - you need to make sure that the saddle fits the slot and is nicely smoothed to be correct - not always an easy task for the novice. if the saddle is to thin and wiggle you can use a piece of thin carton to tighten it in the slot.
in any case use a tuner and make sure that the twelve fret gives you an accurate octave.
needles to say your nut should be accurate as well - by functioning as a zero fret.
if i remember correctly it was lee Marvin
She needs to be professionally measured - to ensure the saddle sits correctly on her, and that it is comfortable for her to bear.
It would help if you phrased your question correctly....Your English is very bad.
To calculate the mensur of a guitar, measure the length from the bottom of the nut above the first fret to where the string actually sits on the saddle of whatever bridge it is.
with a saddle: stick your left foot it the stirrup. then grab the reigns and swing your right leg over the horse. fasten both feet into the stirrups. with no saddle: not sure... sorry
There is the girth, which buckles under the saddle skirt from under the horse's belly; the stirrup leathers, which attach the stirrup irons to the saddle; and there is the martingale, which stops the horse's neck from tossing.
Yes, always loosen the strings on your guitar before you adjust anything directly related to the strings, or touching the strings.
Most saddles can be softened through regular use. However, if this doesn't work after a couple of weeks, it may be best to oil the saddle, to soften the leather. It the saddle is old and used to fit the horse, but has sunk and hardened, it may be best to re-flock the saddle (put in new foam to lift the saddle) so that the saddle fits correctly. For this, it may be best to call in someone with experience and this can be quite fiddly.
At the racetrack the trainer or their representative is responsible for saddling a Thoroughbred for any race. This insures that the saddle is placed and secured correctly and makes the trainer responsible for any added weight the horse is carrying.
The saddle is on the bridge.One end of a guitar string is wrapped round a post (which allows you to vary the tension, and so the pitch of the open string). This is on the head of the guitar. The other end is fixed to the body in various ways. The string is held up off the fretboard and body by a bridge. Where each string crosses the bridge, it doesn't make contact with the bridge itself - it touches a saddle which provides a better contact surface. Usually the saddle is grooved or notched to keep the string in line. If it isn't, quite likely the string will make its own groove eventually. Often the saddle itself is adjustable; some guitars have a separate saddle for each string. This allows the string length to be adjusted and so keep the intonation of the guitar correct. The height may also be adjustable.The material of the saddle can affect the sound quality. Ivory was once used for this, now hard plastics are common on acoustic guitars. Steel or brass saddles give a brighter sound. Electric guitars will have machined steel saddles, sometimes shaped like rollers.
The saddle shouldn't be touching or rubbing on the withers at all. You should easily be able to put some fingers between the saddle pad and the front of the saddle. The seat should be wide or narrow enough to fit your horse's back correctly. The base should not be too curved or straight for your horse's back. Basically, a saddle shouldn't restrict the horse's movement in any way.
Glue should most likely not be used at all. It would be best to call a tack store and ask if they know of a Saddler who could repair the saddle for you. It might wind up being more expensive, but at least the saddle will be usable and correctly repaired.
