All natural. Ash body and maple neck/fingerboard.
the one I had 25 years ago was what they call sienna burst with a maple fingerboard.
Did you get to mess around with the controls yet? If you have the pickup selector switch set for both pickups to be on, the tone controls also function as coil taps. When the tone for either pickup is below 7, that pickup has both coils engaged. When the tone is over seven, that pickup becomes single coil. Since yours has the exposed blade pickup magnets, you should have an easier time figuring out which coil is "on" in single coil mode.
Enjoy it, dude, these basses are real players!
