It's completely obvious that a lack of frets affects your tone but this is about fretted basses... Examples... Would warwick sound different if it didn't have brass frets, but used normal material. Would it be discernible? Another example... Would stainless steel frets sound different than the normal material. (I already know that the clack of the strings against the fret on stainless steel is more noticeable (from experience) but how about after the initial attack?
