I've got a vintera precision,about six months old.my problem is the d string buzzes on the lower frets.to stop it I have to add really high relief,but the frets choke out on the highest frets.its also digustingly crap to play.if I set relief to .30mm at the eighth fret and action at 5/64ths on E at the 17th fret,it plays beautifully everywhere except for the D at the low frets.ive since levelled the frets and it's still doing it.ive tried three different sets of strings,la bella ,ghs precision and fender flats.im at a loss.any ideas?
