I'm pretty sure this was for Guitar Center's 25th anniversary. They purchased a group of instruments with the same specifications, to market as a limited edition run. There was at least one of these basses at each store.
What made these special compared to other Epics at the time:
brass control covers
engraving
inlays
double pinstripe accents
In 1998, the only options for Epic basses were wood tops, fretted or fretles, and right or left handed.
