OK folks - I'm considering going fretless and need some advice!!! I have several fretted basses already, and while I love Spector basses, I don't wanna spend that kind of money to find out I can't hack it. I've read here that a lot of people rave about MIM Fender Jazz basses and how upgradable they are! I have never tried a Jazz, but now might be the time.And later if I like it I can upgrade the necessary bits to my choosing (if I desire!) I reckon that I can get an MIM Jazz here for about £320 (about $450). I'm not sure if the Lined Fretless option will make much difference. I have checked out my local stores and they do not carry fretless basses - I'd need to order it. What are your opinions on this as a starter fretless bass?? Also, if I do go this way, what sort of things should I look for in a Jazz fretless when I go to pick it up?? BTW I'm considering going fretless to increase my flexibility and sounds arsenal. I had considered going to a 6 string fretted as well - but don't know what I'd do with one right now, maybe at a later date. I'd be grateful for any info on my fretless Jazz thoughts that you care to share!! Edit: Yeah, I used the search function on Fretless, got a lot of good info, but thought I'd ask this for specifics!
