I think that i'm not able to allow you undestand what i'm saying.
This is my problem :
how many time i have to say to you ? if i post some personal photos they will be the same of that in the link.
I think that should be line6 to make the corrections in there products before sell them.
thanks for your willingness in help me.
Sorry, your telling lollipop.
You told us, that your problem with your JTV was a broken trus rod, after the replacement of the neck a misalignment of the strings, what could be caused by a wrong angle of the neck. The linked post deals with noise by the wiring of the piezos around the trem. There is no correlation to misalignment of strings!
Next thing is: You have problems with your Italian dealer, not with Line 6. They have to give you warrenty of the sold items and even he will not send your guitar to US for repairing, but will have a certified service center for this issue. So quarrel with your dealer and go to a lawyer if your instrument is still not in order.
Next thing: Not Line 6 sold you an older guitar, but your dealer does.
Next thing: You have no right to insist on the absolut newest production date! But you have the right to withdraw from a deal, when the product is faulty! A guitar will not mature, but a good tonewood will sound better by age. This is caused by some changes in the structure of the wood.
So please come to the right decision and start a court battle with your dealer, if you thing you have the right. But stop nagging around here. A lot of people tried to help you, take it or leave it!
