I have been kicking around the idea of getting a fretless for practice and fun. I figure it's better to start learning fretless now rather than later. Since I like the Precision tone more than the Jazz, I was thinking of getting an Essex P and getting a replacement fretless neck and some replacement pickups. Anyone know how a fretless Precision sounds? I've only tried a Jaco Jazz replica at the store. Can anyone recommend some inexpensive (and passive, if possible) fretless basses that are worth investigating?
