Yamaha GH1

[Ron Giesbrecht]

Hi Stan,

Any chance there has been a historical event i.e.the Manitoba flooding of a
couple of years ago that may be a factor in this situation? In any case I
would be pleased to suggest a few options by phone next week. A serial no.
would be helpful...is this a GH1 or GH1B?...there is a difference.
