I started out with a p bass back in 1989 and although I have used many basses I kept coming back to my p bass, and I never spent allot of time with Jazz basses. Until I picked up a Fender custom shop custom classic this year. Although it has a three band pre amp I tend to run flat with both pickups wide open. To my ears I have to hit it harder to get the low mids to cut through with loud drums and guitar, more than I have to with a P bass or a musicman, but when I do, wow what a sound....and after practicing with it allot I am now getting used to the smaller (than a p bass) neck..I now think I should have gone down the jazz route years ago.
