are some string through? ummmmm
how many times do you wrap the string on the tuner?
some are 3 on a side, some are 6 in a line? help me out here.
side note, some people say that string stretch is a myth, that stings don't "break
in" they settle in the nut, and on the saddles.
enlighten us some one
steel absolutely does relax but not much, still definately enough to cause the strings to go flat within a short period after the strings are installed and then stabilizes, i don't have the reference material right now to give specifics but as part of the job i have been insructed on the properties of metal, the breakin effect is much more pronouced with nylon strings.
now in the case of bending a string and it goes flat then that is more a case of friction/binding as it slides over the nut. if you have a trem and you do a dive bomb the strings will go sharp when it returns.
the length of string being stretched, the tuning, the scale length, the friction, the gauge/alloy string, and the amount of leverage of your hand are what will make the diference. each of these factors has it's own factors. so it gets complicated but a bunch of small thing can add up.
fender bridges have such an extreme break angle it kinks and hardens the string at the saddle and again at the hole in the bridge plate, there isn't much string length and the kink will resist it sliding over the saddle. but not so on some tune-o-matics.
the contact area of the string with the fret and your fingers with the fret board as well as the surface finish on the frets, the fret board wood/paint, and even the hardness can change the friction so even a small change in frets shape can make a huge difference in bendability.
just before metal breaks it hits what is called the yield point, at this point it is most rigid, it doesn't want to stretch anymore. scale length might only account for 3% difference in initial tension but the change in tension will be greater for the same bend especially as you aproach the yield point. tuning has the same effect, you want a fender to fell and sound more gibsony tune down a half step and capo it.
the amount of string being bent does not affect tension directly but it affects the distance a string needs to be bent to acheive a tension. the more you bend the longer the resonating string gets and the more final tension is required for a pitch, this is really negligable. whether your brain interperates more bend as more work or less bend as more tension may vary for each individual.
the neck contour and playing position change the way your hand presses against the strings and will have a preceived effect on bendability.
that's all i can think of now
