OK so I just got my first set of 1200's, admittedly I know very little, I have played violin for 14 years, guitar for 10 and synths for 8 so my musical knowledge is fine though. Anyways, I was spinning in my room and I went to change the record on one of the tables and all of a sudden when I dropped the needle it stopped catching the groove and would just slide across the vinyl real quick. What is doing this? I need to know fast because not being able to spin is making me nuts!
