I would be very interested in hearing how these sound. After all, that really is what I interested in and listen for. (YMMV of course)
As for Gibson making a lam b/s guitar, don't forget that several upper level boutique luthiers make "laminated" b/s guitars and people gush over them all the time.
Of course all of this could be a moot point as
none of us knows AT ALL if these are solid or lam b/s. It's all just speculation on our part...
Just sayin,
