I'm intrigued but you're going to have to be more specific than that, as a 15+ year old Gibson Les Paul bass could be...
Les Paul bass (original, short scale)
Les Paul Triumph (short scale)
Les Paul (small body, regular scale)
Les Paul Double Cut/Money (regular scale)
Les Paul Oversized (regular scale)
I'm not going to count the Les Paul Signature (the one the Epiphone Jack Casady evolved from). You say 15 years ago so I think that predates the ES Les Paul (hollow body, short scale) and obviously predates the Les Paul Junior Tribute (short scale)
Not at all like Gibson to be fuzzy and unfocused when it comes to nomenclature, eh?
FWIW, I kind of miss my LP Double Cut, but not as much as I miss my 1978 G-3.
