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?

I'd vote against that last suggestion. You can get a surprisingly good digital stylus force gauge in 2 days or less on amazon for about $11. Cheers,

Could it be that the suspension on your cartridge has given up the ghost and collapsed, and (at the worst) you're just dragging along on the cartridge body?  
Bpoletti I can take a look. I know the cartridge isn’t dragging but how would I tell if the suspension is sagging. I am ordering a digital stylus and jewelers loupe and have also downloaded a protractor   
Check the VTA - vertical tracking angle. I had a very similar, very frustrating experience recently, and taught myself to adjust the height of the base of the tonearm. I raised it up and then slowly lowered it down in increments until it hit the spot where the sound was clear and beautiful again.
