This is a 4 string bass made by Jackson and is a copy of the extremely hard to find german luthier called Marleaux. It is walnut on front AND back with maple in between. Active 9 volt pickups with active bass and treble gives alot of tonal flexibility along with a scrolling pickup selector so you can blend as much of each pickup you want quickly and efficiently. A few scratches on back that is normal and some wear right above the neck pickup from where your thumb rests. Also has a hipshot d-tuner which can drop your low E string down to a d or c with the flip of a switch. Sounds extremely good.
