1) FIRST, CHECK TO SEE IF IT MIGHT BE SOMETHING AS SIMPLE AS MAYBE THE STRINGS ARE JUST TOO LOW....
2) If the height seems to be fine, check to see if the neck might be "too straight." All necks need to have some relief, otherwise, that little sucker will buzz like a cigar box full of Killer Bees

3) If you think that's OK, then I would check to see if you have some frets that are sitting a little higher than the rest of the gang. If that's the case, this is where I would send up a White Flag, and wait for Dr Danny or Dr. Mel to respond......and THEY WILL.

ok cool thanks for the suggestions. i will do that later. i just assembled this last night. it is morning here in Cebu Philippines...
