Hi Steve,
At the time your Essence was made... they were all the same! Here's what I found in the file for your bass:
top: Flame Maple
accent: Walnut pinstripe
body: Maple
neck: 3-piece Maple
scale: 34 long
fingerboard: Ebony
inlays: none
pickups: MXY
electronics: Essence
originally made for: Dan's Music & Sound, TX
birthday: June 12, 1991
The pickups likely had the hot stamped name wear off, either partially or completely. A previous owner may have also sanded it off it was partially worn.
Also there is an Elan marching around with the 6570 serial number as well - sometimes we make a duplicate on accident!
I'm going to add that I think the top may be Eastern Maple, but it's not recorded - just my observation.
