I have a JTV that had some problems when I got it home. Battery life, model selector and first string slipping out of the nut...frequently. I opened a ticket and had to ship it to line 6 for repair. I was told it got a new neck and setup, battery replaced ( although I was told the original was fine?!) and model selector switch fix (was told it was a common issue)
When I play my first string even unamplified you can hear a ring or harmonic. When I lay my finger behind the nut ever so gently like I'm trying to create a harmonic it goes away. These are not inexpensive guitars and I continue to read about issues. The features the company advertises are desirable. Obviously many of us have purchased them because of what they promise. I wish the company would make the products they advertise deliver on the promise of function and quality.
