I just picked up a fretless Fender American Jazz Bass that came with flatwounds. I just don't care for the dull, lifeless sound of these strings. What is a decent roundwound or bright flatwound string that will give me that singing fretless tone but yet won't eat the unfinished rosewood fingerboard at the same time? Thanks! Also, isn't there a trick to properly set up the string action to get the right amount of "mwah" factor out of a fretless?
