Have you considered taking this instrument of yours to a local guitar uber-technician in Vantaa?
Is the buzz in the neck a resolvable issue or is it a showstopper?
At any rate I feel your pain. I love my Ibanez electric bass except for the frett buzz it lets out when really low notes are hit. It pretty much ruins the sound IMHO and I have yet to take it to a technician to get it setup properly. A friend of mine told me to try "flat wound strings" to try and fix it, but I doubt such a string is made for an electric six string.
Good luck, OVM (You forgetful bastard!)
