I was an authorized repair tech for Fender and many other companies until I retired in 2006. A local music store, a Fender dealer, took in a Shuttle Max 6.0 in trade, and it is severely faulting. I took it home to look at it. It passes no sound, and all status lights just flash, all together. Do I go through Fender to get service info...service manual, technical service bulletins, etc? I've been out of the loop for a few years. I'm hoping a knowledgeable TB tech can steer me in the right direction.
