Although the P bass may be the best selling bass of all time, I've always felt that the Jazz has the most perfect design for comfort and playability. Although other basses may have many of the same features, few have all, and Fender was the one that did it first. Here are some reasons why I think the Jazz has the perfect design. 1. Leo's big contribution to comfort, the contour body. 2. Pickup placement. Beyond even the benefits to sound, the two pickup placement allows many finger players a thumb rest in two positions for sound versatility and comfort. Many players have adapted to this style. 3. Bridge design. The simplest and most inexpensive design of any bass bridge. Allows for easy palm muting, as well as easy setups. Or, add a bridge cover with mute (it's one flaw, no string spacing adjustment). 4. Neck shape/width. Although, like everything else on this list being highly subjective, there is a reason so many people love that thin Jazz neck, for speed and comfort. 5. Is there any other bass that is easier to work on? The modular design allows for easy upgrades. Easy access to electronics -- 3 screws on the Jazz. Easy neck repairs/replacement. High availability of parts. Saves time and money. I know some people don't like Fenders in general. Was any other bass created with a more perfect design?
