Sur le site de Status Bass, dans la FAQ, il est question d'un dead spot.
Voici le paragraphe:
All basses, no matter how they are made will have some natural resonances. If these resonances happen to coincide with a particular note on a neck this may make it either a louder or quieter.
I'm sure you are well aware of the classic dead spots on many Fender basses at the 5th - 7th frets. The strange thing is that some Fender bass owners have almost no problem whereas others are virtually unplayable.
Dead spots can happen on any bass, whether graphite or wood, but tends to be much less pronounced on graphite basses due to the higher natural resonant frequency of the material.
If you have any problems I suggest you try checking the action, intonation and general set-up. Make sure the strings are OK and that the small locking screws on the bridge are not loose... not too tight though! All these factors can have an effect on the way notes resonate.
