Since stainless frets have less friction against strings,when you are sustaining a note using finger vibrato, do the notes die quicker or is the sustained note quieter due to the lack of friction? When you vibrato a note with finger you are essentially "bowing" the string by rubbing it against the fret-similar to but not limited to the"Foxy Lady " effect .This is for long sustained notes , violin type things as well. Will I get less of this bowed vibrato sustain effect with stainless due to less friction if I order stainless? People who have both stainless and nickel will be able to help here . Thanks.
