Almost certainly I have played a Jazz Bass before. Yet that experience was so long ago I couldn't have told you beans about a Jazz with any certainty. What I remembered was: Fender Jazz, well whatever. Hardly intended as a Fender slight, then or now. I like Fender. And I found myself a welcome guest in Donegal, and am asked to play. I have my amp with me but my bass is in Achill .... And this is what I observed: The Jazz is really comfortable to play. First thing: to me, it's light. The borrowed Jazz has a 2 inch strap, and the first thing I think is: bass is light enough to use a 2 inch strap. And I like the neck. Now it's true, it's not my neck (which as we all know is teh besto only because it is mine and I've not played anything but mine for decades). But it's a good neck and I can see getting comfortable with it. It's very playable, this is my next observation. I notice my right hand finds a different position to get the tone I want. That's closer to the bridge than I normally play. The tone: who knows? I'm on a borrowed amp on a borrowed bass with $deity knows what kind of strings that are set up kind of high to my own taste. So: who cares? With some experimentation I figure out how to get a tone I like and it is good enough for the evening. My take: nice bass. Still like mine better. Big surprise, we do that, if only out of familiarity. It's really comfortable, I'll give it that, and while I doubt a Jazz would be my BFF I wouldn't turn it away as a stranger.
