My WAV4 has been kept in its original NS padded gig bag, in a smoke-free home. It is in very good condition and plays and sounds perfectly fine with no issues at all related to its neck, action, frets, electronics, etc. There are some light scuff marks between the neck and neck pickup (I had put a ramp there with double-sided tape. You can't even notice it in the photos), and there is a very thin crack in the paint finish at the neck/body joint (which was there when I bought the bass, and it's purely a cosmetic blemish. You can see it in the photo). Included is the original NS padded gig bag (very high quality. Nice and stiff and thick) and adjustment Allen wrenches. Buyer pays for shipping.
A point of note on these, the bridge is all the way to the back, so these basses feel smaller than than they are. GLWTS.
It feels perfectly fine, and in fact it's one of the most comfortable basses I have. The only reason I'm selling it is because I have too many basses. I would love to keep it for its unique acoustic piezo tone and very clean/clear EMG pickup, and the range in-between, as no other bass I have can achieve that type of sound. But six basses is the limit I've given myself and I'm already over that limit.
