This is an FGN Mighty Jazz Private Reserve Bass. Its been built as the ultimate passive Jazz bass so to speak, made by the Japanese Guitar Fujigen company in Japan, responsible for a lot of Fender Japan guitars and other prestige instruments.
Amazing quality, and top of the range for them, rather like their custom shop as far as I know.
The bass features:
A two piece ash body in tobacco burst
24 fret Maple neck with maple fingerboard
Black pearl inlay markers
Passive Jazz bass electronics with V V T controls
Black scratch plate and black hardware, hi mass bridge and gotoh vintage style tuners. Bridge is strung through body or top loading.
Really nice action and the fretwork is amazing.
