Thanks SR- I should have included included that once the mods and adjustments were completed, the saddles were lowered till there was string buzz then raised again.
My experience so far has been If the string buzz occurs somewhere in mid neck- the truss rod probably needs to be loosened to make a little more bow. If buzz occurs
at the first or 2nd fret, the slots have probably been filed too deep. Sometimes you can fix that using a mixture of super glue and baking soda (or something equivalent)
but if you do this on the high "E" or "B" string, the string will eventually wear it's way back down toward the frets. If the buzz occurs above the 10th fret, the bridge or
saddles need to be raised or there is a high fret (if they haven't been leveled) . So at this point, mine buzzes at a random place once the saddles have been lowered
past a certain point. But the action is still too high. I guess it should be noted that string buzz just about anywhere on the neck can be alleviated by raising the bridge.
Hope that helped.
