    It's neither almost nor exactly those notes.

    One problem with that if it's 1 octave too low, then the calibration machine would have serious issues because the tensino would be like way below 20 hahahah!!

    It would not really matter if the strings are Ti or not, what we mainly paying attention to is the note or freqency it makes.

    According to you, ur c# is around 23/25 (seems off about 2 lbs compared to old hand's). Using this as a base, ur E is at 25/27, so 23=c 24=d 25=e. Every lb seems to be 1 note letter for you.

    For old hand, every lbs seems to be a half note.

    Someone stringer might be off (not calibrated) or different material is used.

    if you have tuning fork, it is made of a certain metal. You can't use a piece of wood of same size and shape and recreate this frequency, can you. or maybe a different metal eg. aluminum and recreate this frequency. so material does matter too. Same thing with piano strings which is why you need to tune it and different strings are tightened a little differently to produce the same sounding frequency.

    If you both have the same strings, (racket frame might be different but itz just graphite.) then it should sound quite similar, if it does not, someone's stringer isn't calibrated correctly =P

    btw... i say that there is a difference when you use a different string because of the gauge too. i hear difference between a bg66 strung at 28x30 and a bg 65 strung at 28x30 i would not attribute it to be off my 1 whole note, but maybe a sharp or a flat (which is some other key's sharp).
    when i string a TI and i compare it to non-ti, the metallic sound in the TI throws me off a bit.

    It's all DinkALot's fault :p

    He should have made the video with freshly strung racquets.
    Not after putting them through some awfully mighty hits :D

    You can be sure that the overall tension must have dropped by more than a few notches after that mauling.

    My fresh 27 sounds like his used 29.
    As such, my 27 is nearly the note D.

    Maybe the panda will find some time to take this further ;)

    I think you meant to quote me since I was the one who said C# is around 23/25, random estimate since I forgot that one is 1 lb once you get a base.

    Just to clarify, yes it was two different strings and rackets which made it confusing. Provided below is my data to clear things up.

    For my ArcSaber 10 and 7 (crank). Base E = 25.5/27.5 using NGB98. D= 24.5/26.5, C = 23.5/25.5, and so forth.

    My friends NS9KX using NGB95 (ECP). Base D# = 26.

    Awesome video, another thing I found out was that you can't compare the sounds of different tensions with different guage strings never mind different strings. 0.70mm always sounds lower than thinner strings @ same tensions!

    May be when I have 14 Arc 10 in hand and string them up from 18x20 to 31X34 and play a song with them?

    Great GrandMaster SH, you will need a new machine for your 31 X 34 lbs string job :D.

    For the Never Greater Panda,
    It has been ordered with your sweaty band. I should be here this week and i will send it to you ASAP.
    For Peter the Greatest,
    I will use the Babolat Star5 in the shop. The Alpha machine is missing the tension head (tension head was mounted backward) and sent back for repair. Should I play your favorite song "Me So H!@#$Y" when I string them up?

    Greatest GrandMaster SH,

    Please take photos of the Star 5, with the badminton kit, in action. The sight will be the most stimulating. Yes baby, 31 lbs main X 34 lbs cross :D. Remember to activate 10% pre-stretch.

    actually, master SH you can already play that song when you string at one tension because when you string mains, due to the different distance in string, they are already creating different notes =P hahaha...

    Yes I would agree. Thicker strings stretch more while thinner strings pull tighter.

    I do believe (not sure if it is confirmed) ECP machine is used, the machine would be able to compensate for that and then pull it accurately regardless what thickerness it would be. Compare it to the crank where it does not have this ability that one would have to increase the tension to compensate for the guage differences.

    Actually, it is due to the physic. Given 2 strings are same length and same tension. If the density of the string is the same, the thicker string will have higher mass. The thicker string will have lower tone under same condition.

    Great GrandMaster SH, we are waiting for the Babolat Star 5 string job. Let's hear the "ting" and do a comparison between Great GrandMaster DinkALot's ECP and the Star 5.

    So sorry! Silly me!

    The string on all the rackets were Ashaway ZGut X1709 (0.73-0.74mm).

    So, the string pitch will only be higher on thinner strings.

    My bad! I'm so used to typing "MP". :eek:...:p


    Hopefully one of the mods can edit my post.
