Hi Mike,
Glad you are loving your Europa. Here's what I found in the instrument file:
serial number: 92U7129
model name: Europa
model number: ULB4
top: Flame Koa
accent: Maple and Walnut pinstripes
body: Mahogany
neck: 5-piece Maple and Purpleheart
scale: 34" long
fingerboard: Ebony
inlays: Pearloid (plastic) ovals
body shape: Europa
peghead shape: Europa 4
pickups: Alembic MXY
controls: volume, pan, filter, Q-switch, bass cut/flat/boost, treble cut/flat/boost, mono output
originally made for: Rock Block Guitars, TN
birthday: April 7, 1992
The original owner was in Tennessee.
Installing LEDs after the fact is approached as remanufacturing. We remove the fingerboard, we reuse the original if we can or we make a new fingerboard, install the LEDs, reglue the board to the bass, do inlays, refret, route new battery compartment, make new backplate, and refinish the edge of the neck (or the whole bass depending on your wishes and budget). I'll have to take a look at some images to confirm it's possible to do the work before you would send it in. I can give you an idea of cost after I see the pictures to make sure there aren't any surprises
