Hi, i just put new pickups and strings. I previously had flatwounds (can´t remember the gauge) and i put the Elixir 40-95 know. I notice a buzz when i play from the 5th fret to the last, even when i play very light. From the 10th or 12 fret it gets worse. My neck is a little curved, but without the strings it was a perfectly straight line. I´m affraid that if i tight the neck, the problem gets worse. I thought maybe the action is to low, but it doesn´t seem that way. From the end of the neck to the bottom of the string (without pressing any fret) there is about 3mm (0.12 inches) relief. Is this too much or should it be higher? Thanks for all your help, i´m really worried here.
