Just throwing it in there. Alembic cases are not the same for all models even after excluding the models you suggest. They are different depending on the bass. Short,medium, long short scale, 4,5,6 string, or body shape. There is no way a classic large body or MK signature is getting in that case.
To avoid issues, i would suggest listing the basses you know for certain would fit that case and reword the listing.👍🏾
