This is the one from E-bay, right? Well it has a fast medium neck ... one voulme knob for each pickup, one ACTIVE tone knob and an added Q switch which will change the midrange tone when used. I have a very similar bass except mine is a persuader. You'll probably want to lower the P pickup and raise the J pickup all the way because the P pickup is much more powerful than the J. that way full volume on one pickup will be balance with full voulme of the other. Also if it's like mine it's not too heavy but rock solid and very well balanced. I loved mine so much (It was my 1st Alembic) I now also own a 95 five string Epic and a 96 Stanley Clark Signature Standard. Once you play Alembic very few people go back to other brands. BTW ... by the serial number it's an 88 not an 89. I saw that in their add, they were mistaken. My Persuader is also an 88.
Enjoy your new baby!
