Hello there.  I picked up an Alembic a few years ago, and I would like to know some more about it.  As you can see in the picture its a fretless bass, with passive electronics, and the serial number is 86 S 4045.  Anything you can tell me about the bass, such as what model it is, what type of wood it uses, anything would be helpful.
 
Thanks,

Hey there Mario. That's a gorgeous Spoiler model! Top is Zebrawood, back is probably mahogany, neck is all maple, fingerboard is ebony. The electronics are not passive, it has a low pass filter and Q switch to boost the range.

I would check the battery comapartment if you think the output is a little low and to make sure it hasn't leaked!
