You're a fantastic teacher...keep up it! There's one question, though, that I can't seem to get out of my head when it comes to marking up the records so you can find where the scratch sound is. Putting a piece of paper on the inside will point to the place like a hand on a clock, but what I can't figure out is how to find the right groove on the record. I mean, it's less than a millimeter between each groove, so how can you mark the right one? Or do you even need to?cheers mate
