I’m not actually sure what this bass case is for. I thought a les Paul bass and the one I have from the 90’s fits except the case isn’t deep enough and the 3 post bridge doesn’t fit so maybe this is for a studio Les paul bass or an EB? Hopefully you can use it. It has keys. Measurements inside are 46” L lower bout 14” upper 11” body area 17” L headstock area 7.75” w depth of main case 2.75” depth of lid 1.25“ all measurements are close but maybe I’m off by 1/16 or something and taken without smashing the foam
