hi guys, I need your advice on something... So, 6 months ago, I decided to buy a Brand new Fender Jazz Bass Classic 60's from a local musicstore. Its been just fine up until recently that is... It started buzzing all over, between the 3rd and 9th fret, all strings. kindof suddenly. now, without even needing to look at it, I know that the neck is bending backwards. this is bad. Now, it COULD be from the change in temperature recently, but the thing is that once the wood starts warping, it will have a tendency to keep doing that, eventually killing my fretboard entirely. Now, Im about to go up to the store and ask for a new bass. I think Im entitled to it, since its still in warranty. What would you guys do in my position? would you settle for a free setup at the store? thinking that this problem might reocur?
