Is this what I have? (I attached the picture) My friend let me borrow this indefinetly (He stopped playing bass). I'm assuming all FNA types have only one $ pickup? What does the volume knob do--it is a pull up/push down thing. Does that switch from active to passive? Also has anyone had issues with the D&G strings sounding faint? The action is a bit high so I'll adjust that tonight. edit: The serial number is m055845-98 so I'm assuming it's from 1998 correct?
