I'm setting up my 6 string floating tremolo height after changing the posts (typical Ibanez swap to newly designed posts). Looking for opinions. I set this up so that the first 4 strings do not really buzz at the higher frets. 5th string has some buzz against the frets and the 6th string more. I know there are many variables like the quality of fret work but do you generally accept some string buzz or go for a "buzzfree" sound (Marty Friedman said he doesn't like any buzz).
