So, I've had this '08 Fender 70's Classic Jazz, since new. It's been my main squeeze since the day I got it. I mainly like the thickness of its neck and the classic Jazz Bass tone. But a few weeks ago, I picked up a Yamaha BB424X. I just fell in love with the almost unfinished feel of its neck. I've been playing the 424 just about every day since. Great, great bass. Well, I picked up the Jazz to run through a practice and I immediately noticed that I didn't like the feel of its neck anymore. It's plenty fat the way it was before, but the back didn't feel as comfy as the Yammy. So I did it. I voided the warranty. Spent about 10 min. with a 220-grit...sanding. I'm not really too worried about the warranty, since there's about zero humidity here. But now, I don't know when my other finished-neck basses will get played, unless I sand theirs, too. I'm not too worried about any devaluing, since I don't have any real expensive stuff...well, except for my '80 Ric 4001. I might not really jack with that one, although its already got a Hipshot bridge, Ric replacement keywinds, and StrapLocks. But then again...I might. Anybody else void theirs?
