Hi, I purchased a JTV 69 from a shop (display model) the guy said the battery had run out so couldn't see the Variax mode. I already have a Variax 500 and so a flat battery didn't seem much of a problem. Since then I've charged the battery and on power up the Model selector knob and altered tuning knob flash red continuously . I've looked through manuals and online threads and appears simply pushing the model select knob should be enough but not matter what i try the flashing just continues. I've tried different power sources (DI box and batteries) and powering up with 1/4 inch while having model select knob pressed down and pickup selected in the middle but still no result. I will be contacting line 6 tomorrow but in the meantime has anyone got a solution or suggestions?
