Well when I opened the case the next day. There was a bunch of sticky stuff on the bass itself. I cleaned it off and once I played, I noticed the strings were dead. Ol boy that played my bass was eating right before hand. So im guessing he didnt wash his hands too well and whatever sweat and other crap was on them, got on the strings and mellowed them out badly.
I wouldn't let him handle it again, let alone play it.
