I'm saving up to someday purchase a Warwick fretless (I fell in love the first time I saw one!) and I was wondering if and how the flatwound and fretless combination affect a bass' sustain. Should I expect the sound to be a little or alot duller? The reason I ask is, say I hit the 9th fret on the G string (roundwound D'Addario), I expect it to sound out for a bit (nothing outrageously long, it is a bass after all!). Can I expect the same sort of reaction on a fretless with flats or will the note just fall right off? Thanks!
