Sudden problem with turntable

If the problem was really a stylus booger you should hear immediate improvement after a soft brushing.  Let us know if it removed the muddy sound.  I also use the magic eraser and SpinClean.

+2 Magic Eraser. +1 just wasn't enough. Cheers,

Before trying anything that will cost money... Did you try putting the same lp on that you listened to last? If so, it could be you're now listening to an inferior pressing?

Could you or someone bumped your counter weight and added tracking force, your head shell screws were loose and cartridge moved, to troubleshoot you could back off on tracking force or adjust vta. Did you check the suspension of cartridge was riding low close to album? I use magic eraser, I have a vpi machine but get best results cleaning albums with a hand held steamer with cleaning solution and rinse with lab water or distilled . Hope you find problem it can be aggravating, been there.

I tried the magic eraser and that wasn’t it. I think I will need to check everything from scratch, including cartridge setup, platter level, ball bearing lubricant....Never done that before so it should be a good learning experience. The odd thing is it seemed to happen quickly went from sounding good to slightly slow or hollow. Just missing something and I can’t put my finger on it. Very annoying.
