I have a JTV69 and it is a terrible guitar, I have had nothing but trouble with it.
It has been back to Line6, I expected a sorry and a new guitar but they sent it back to me telling me it was of standard quality. You can't even intonate it properly as there is not enough adjustment on two of the screws, to me it looks like the bridge is in the wrong place!
I would steer clear of them myself.
