I realise this is going to expose my ignorance big time, but for the first time a few days ago I played a Fender Jazz Bass. My friend got it for £800 used, and it's absolutely brilliant. I feel in love, instantly. I think it might be a special edition - the only distinctive feature I can describe though, is the lack of front plate. One of the things I liked about it most though, was the seemingly low-set frets. Is this a feature of J basses in general or was it just because this was an old bass and the frets had been worn down through use? I've seen J basses online and they describe them as having 'jumbo fretts' - i take it this is more to do with the scale than the actual height of the fret metal from the fingerboard?
