Here is a New Old Stock Yamaha BB-N5A 5 string bass serial number 85K1005 from 1998. The bass is in MINT condition, with only one small ding near the strap button on the bottom of the body (see photos).
The Yamaha BB-N5A (Nathan East signature 5-string model, manufactured in Japan from roughly 1995 to 2000) features an alder body with maple top, active electronics, and a 24-fret maple neck, rosewood fretboard and 24 frets.
The transparent blue finish actually looks like more of a turquoise colour.
The bass is set up great, it's easy to play, and sounds as good as it looks!!!
It comes with what appears to be it's original hard case, and control guide is still on it the bass.
