Hi Jack,
Here's what I found in the instrument file:
KLB5 Essence 5-string bass
top: Quilted Maple
accent: Walnut pinstripe
body: Rock Maple
neck: 5-piece Maple with 4 Walnut pinstripes
scale: 34 long
fingerboard: Ebony
inlays: none
pickups: Alembic MXY56
controls: Essence volume, pan, filter, mono output
birthday: December 28, 1994
originally made for: 1995 NAMM show display
The sustain block was standard for the 5- and 6-string Essence basses, but not the 4-string version.
Enjoy!
