Hey guys, I just got a new Peavey Cirrus, and I'm experiencing a weird problem on some of the frets. When the bass is plucked normally, I get no fret buzz at all, however, if I press the string down on a few frets (off the top of my head, the 24th fret on all strings, and somewhere around the 17th fret or so on the A & D strings, and it was happening on the 12th of the D but it seems to come and go) either while tapping or sometimes just in fretting, I get a very strange clank/sustained rattle like a "mmmEOOOooorrrbbbzzt". In fact, I can't even tap on the 24th fret of any string because it's so bad that the tapped note doesn't sound clearly, even if I lightly press the string down. I normally would think that the neck needs to be straightened, but it's fine, and straightening it doesn't help the problem, so the only other thing might be the culprit is that I need to get the frets leveled (irritating for a new bass, one that is raved about its playability). But, because these frets don't buzz when I pluck, and only when I press down, I can't imagine that that is the problem. Any ideas?
