I had high hopes for the JTV-59 I just purchased but cannot get the guitar to connect. I've tried 4 different USB cables, 4 different Cat5 cables, 2 different USB interfaces (went back to store and swapped for another one), 2 different computers... all of this and multiple attempts to get it to work. But the LED on the guitar side would never go 'green'... just slow blinking 'red'. Have given up, and will return the the guitar to the store at my ealiest convenience unless someone here has any suggestions.
