Question: Info on 1999 EBMM ASS MM90 w/Piezo

I’ve been poking the Interwebs for information on my 1999 Axis Super Sport MM90 with piezos, there doesn’t seem to be too many of these around and very little information on them. Aside from the specifics on control usage, I’d also like to get an idea of what the original price was on it as well as what its current value might be.

She was purchased by me from a collection in what I’d best describe as showroom new condition, not a scratch on her and hardly played if at all. She’s sporting a Trans Red finish with matching headstock and the rosewood fretboard on figured maple neck.

She’s been sleeping in the original G&G vintage case (still has some blue protective plastic on the latches) and surprisingly has the original hang tag and case candy as well.

Thanks in advance for any info anyone can supply. It is appreciated.
