I'm considering buying this cheap, battered Fender Aerodyne bass I've seen on eBay and taking it to a luthier to defret it. I already have an Aerodyne and I love that kinda model because of the fast neck, matching headstock and the general lightness, and thinness of the model itself. But now, I'm considering just buying a j-bass which is already fretless (and similar to the Aerodyne), but specifically under £500 ($630)? I'm not interested in any Jaco copies by the way. Cheers!~ EDIT: I have decided to modify my Modern Player jag bass (strip it's body, to give it a natural finish and add more switches to it, so it resembles a more up-market jag bass), instead of buying an old bass to get it defretted. I know that's completely different to my original plan, but for some reason, things have went that way. I'll get a fretless bass soon, as I'll settle for any good looking/feeling jazz bass in my price range. Thanks for all your replies!
