Just received my new Am Series Fender Jazz. Two questions - the sustain doesn't seem as good as my Fender P or my Stingray (both amplified and unamplified) Is this normal?. I know its supposed to be noticeably thinner than the P sound but the sustain is pretty short. Also - there's a bit of buzzing above the 5th fret when I push hard on it - could be because of the temperature change during transport (west coast to east coast). Is this normal? Love the neck on it just wondering if the thinner sound w/less sustain is normal. If so I guess I just have to get used to the Jazz sound. The whole tone, resonance feels cheap compared to my Stingray - that could just be because the 'Ray is well over 10lbs though. Trying to figure out whether or not to return the Jazz.
