Sudden problem with turntable


I have a rega p5 with a ortofon black. it used to sound great. yesterday i put on a record and it sounded terrible, really muddy. My knowledge of turntables is very limited. Is it possible that i damaged the stylus? Any suggestions as to how i would determine what happened?

No love for my suggestion that would have cost you nothing. Too late for it now. Good Luck!
It’s the same physical album I have listen to many times so unfortunately not the pressing. 
Do you have HiFi News test lp? That might offer some clues...cheers,

Take the cartridge out and send it to Soundsmith....you'll get back smiles again.  Don't bother with anything else since this happened suddenly....not a setup or cleaning suggestion.
Do you have other sources? Sound okay? If not, could there be blown tweeters?
