For me it was a 4003 Ric and a T Bird. I wanted to bond with both, but something about the end of the neck near the nut and the neck dive on the T-Bird just turned me off.
My first bass a few years ago... a Fender Dimension (remember them?). Did what it was supposed to do when I was starting out but for some reason it never seemed to come alive in my hands. Couldn't relate to it. Not had that feeling with any bass since.... every bass in my small herd feels right the moment I pick it up (even my fretless, once I get over the struggle of trying to play anything in tune LOL).
