Dan01,
I guess you're thinking I'm a little crazy buying keyboard but you're wrong.
Of course I know the person I bought the keyboard from.
I'll explain: I bought the keyboard, I brought it from the store, still on the closed box, but when I opened it at home I saw some scratches on it (it had arrived to the store that way).
Then I said I wanted a new one and they came to my home, they took the keyboard and in the same day they brought me another new SD1.
This FINAL SD1 has this pitch wheel problem, And maybe you aren't understanding another thing...it's a very little distance problem on the pitch whell, you wouldn't find it at first. I only noticed that because of the error message that sometimes appeared turning the keyboard on saying that the "pich whell position is not default".
And I HAVE the store near me, but they can't fix it, they have to take it to their dealer and I didn't want to wait right now, that's why I'm asking if I can fix it myself.
Have I made myself clear?...
