Hey Psark ... I live very rural on a gulf island, west coast Canada. Taking it to a service centre in Vancouver is not realistically possible (too far, too expensive, three ferries etc.) and sending it by courier both ways is expensive but it would be the only way I would consider, coupling it to the cost of the service would be very expensive. I would try anything first that I can do myself. Neck relief and action is fine. All Piezo's work. If I could just turn those adjustment screws and move the saddles I'd be happy. I did intonate string 2. String 1's saddle is definitely too far back. I am hoping some penetrating oil might free that adjustment screw, but like I said, I think it is fused to the saddle?
Another question ... are the Line 6 Li-Ion batteries available now? Yamaha Canada said ~8-12 weeks from time of order?
