I have a 2001(?) model American J bass deluxe. I have no plans to sell it but I'm wondering if people mod these at all? The tone is nice but I'm hoping to get a little more "fatness" out of it. Also, the Fender "Noiseless" pickups make a buzzing sound when I'm not touching the strings. I've removed the bridge and elongated the grand wire but it still buzzes. Perhaps some Dimarzio Ultra Jazz's would be a good idea? Any ideas?
