Hello, I just got a used jtv69 serial#11090182 can anyone tell me is this a version one? where can I get a replacement trem bar? when plugged into HD500X with RJ45 the power seems not to be stable.does the input need replacing? the model knob does not turn on and off reliably it takes a couple tries usually. is this common? I like the guitar but do not want to deal with touchy electrical stuff. anyone out there experienced with these problems and or solutions to them ? thanks in advance for any help.
