If this has already been covered and I am being redundant, I apologize. But here is my situation: The brass nut on my Spector was really worn out and needed to be replaced. The action was way too low and the "A" string would rub against the fret board thus creating a terrible buzzing sound. To correct this I placed small pieces of paper in the groove of the nut so as to lift the string, but this becomes a problem since the paper will fall out eventually. Anyways, after locating a Spector retailer in Canada I called them and ordered a brand new brass nut for my bass. Now, here is my problem - After installing the new nut, the action is much too high - especially on the 1st, 2nd and 3rd fret - and therefore I will have to grind down the nut. My question - Is this a task that anyone has completed themselves? I never ran into this kind of issue, and do not want to ruin the brass nut (which cost me over $70.00) that I ordered. Do you think a guitar repair shop will charge up the @ss for this kind of work? Money is not too big of a problem, but if this is a simple task that can be completed with a grinder then I may give it a try. Any other suggestions?
