Hi Roberto,
Here's what I found in the file for your bass:
91P6486 Persuader PMB6
top: Walnut
accent: Maple laminate
body: Mahogany
neck: Maple and Purpleheart, 32 medium scale
fingerboard: Ebony with pearloid ovals
pickups: AXY56
controls: 2 volume, filter
originally sold to: Swee Lee, Singapore
birthday: April 19, 1991
I guess this one and the 5-string Persuader (91P6489) were in the same consolidated shipment to Singapore.
In July of 1999, the owner of this bass wrote to us that he purchased this bass and sold a Europa 6-string because the smaller neck size on this bass was better suited to his hand size. He also asked about pricing for changing to Europa electronics, but there isn't any note that he had them installed.
