JDX,
I have two close friends in the UK who played Yamaha keyboards for decades. After reading my rave reviews of my SD7s they both decided to purchase a SD7. The downfall was the lack of interest and lack of technical knowledge by the selling dealer in the UK. They finally gave up and traded the SD7s back to the dealer. Like I said in my PM to you, I would contact AJ and see if he can help.
