Distorted Sound, extremely tinny (first turntable)

Pretty much the title. I received an LP120 (original not x) as a gift and have had issues after setting it up. Vocals are extremely distorted, there is no bass or mid, and it just sounds extremely tinny and not useable at all. Not sure what the issue is as I thought i set it everything up right. was wondering if there were any suggestions for fixing or if one of the parts is just messed up. Sorry I am a newbie but what really appreciate any help, thank you!
