Hi Mario,
Sorry this has taken me so long the research, but I finally have some details about your bass:
top: Burl Maple
accent: Purpleheart laminate
body: Mahogany
neck: 3-piece Maple with 2 Walnut pinstripes
scale: 34 long
fingerboard: Ebony with Pearloid (plastic) inlays
pickups: MXY4
controls: volume, blend, filter, Q-switch, bass c/f/b, treble c/f/b, mono output side-mounted
finish: Satin-natural Polyurethane (now discontinued)
birthday: January 16, 1997
There's nothing else to report - except that you've got a beautiful Alembic bass.
