I am thinking of buying the new 2012 Fender American Standard Jazz Bass Fretless and have one at home which I can send back. This bass came shipped with flats even if the specs at Fender.com says it should have "Fender® USA Super Bass 8250M" strings. Anyhow, I really dislike flats especially on a fretless where I strive for open tone and lots of "mwah". So right now I am not too impressed with the sound or feel of this bass. It sounds a bit dull, one-dimensional and unresponsive, at least with my limited fretless skills. (I have another fretless with ebony fingerboard + rounds and that bass sings.) Will the rosewood fingerboard on the Fender bass survive the use of nickel rounds? Will it still be dark/dull with such strings? I read here on TB that the fretless MIJ Jazz version rosewood was extremely hard wearing but I did not find much info on the MIA one. Thanks!
