First off, full disclosure. I'm a newbie bass player, been playing only for a year. But I'm a pretty good guitarist. I've got a pretty nice Fender Jazz Hiway One. Love the instrument. I'm in my first band on bass, playing Surf. This is the first time I've really gotten to play out, and at reasonable volumes. I love the way the bass sounds in the low and mid registers. But I'm not getting the sustain I expected up in the high register, on the high strings. I'm not going much above the fifth fret or so on the D and G strings, but I'm not getting the sound I expected. I'd rather play on those strings than on the lower strings at higher frets. Is it the bass I got, or is that just how it's supposed to be, that those strings plunk, and sound loud, but don't sustain.
