hello im new to this site but it seems really cool and informative. Well here it is i went to a local music shop recently and bought a guitar a used ibanez js100 satriani sig guitar i got it for 465.00. The guitar looks nice only a couple little dings in it and is a very nice looking guitar. So i get it home and im playing around and i decide to wipe it down a little thats when i notice something. On the back of the neck where the holes are for the bolts to hold on the locking nut are 3 cracks one 3 inches long and the others about 1 inch each. At first i thought maybe they were just wood grain but after sliding my thunbnail across them i can feel them there. my question is what would cause this and would you get your money back. I emailed the store and they told me i could bring it back and get an exchange or a refund if i want. A buddy of mine who looked at it says it probably wont give me trouble but everytime i pick it up now it is all i see lol. im thinking about getting a refund and buying a brand new ibanez sz520qm or a sz720fm. all comments are welcome thankyou. oh ya if anyone wants to see pics of the cracks let me know and i can email them to you. thankyou
