Thanks everyone. The JTV-89F is at the Authorized Repair center (for about 2 months). They just started working on it and found that when power is applied, no activity on the main (DSP, I suppose) board. Not sure if this is hardware or software, I'm guessing the repair folks don't either, so a new board has been ordered (with my permission for the cost, since this problem occurred JUST out of warrantee). I know the backlash I am going to get for this comment . . . But I purchased a Gibson SG in 1985, and it works today JUST like it did then, which is JUST LIKE I EXPECTED! My over-tech-burdened LAB SERIES amp lasted 10 years. I honestly expected more than 3 years from a Variax. I know, MY BAD! Oh, and, I realize I don't need to spread this message any longer . . . EVERYONE I speak with says something akin to "I would NEVER own one." So. again, sorry for the overabundance of venting. I see I am only a tiny fraction of those that already know. But, please forgive - I honestly thought I must be the only one, or one of a few. I should have researched a bit more. Why am I paying for a refresh? Two possibilities 1) Too stupid to realize this will not last as long as the original and; 2) Really good idea, though BAD implementation - I LIKE what it does . . . WHEN IT WORKS!
