As long as you had the original registrations stored elsewhere you would be okay in doing enough for you to get by.

Sorry to hear about your S900 problems, Don...it can be so disappointing...I was lucky and got a good one.

From what I can gather from Yamaha Canada, there has been no problems in this neck of the woods...seems to have been a bad batch that slipped through quality control and were mostly shipped to the USA.

Good luck with your gig.
