Top post on on rthedonald right now . <| sep |> Well it entirely depends on the material the slit is made of and the kind of wave it is , if it is a light wave and the slit has a highly reflective surface it ' ll bounce off , if it is made of a non reflective surface most of the light will be absorbed and the material will heat up , if it is a mechanical wave it ' ll bounce off but how much it does so will depend on the stiffness of the material I guess . <| sep |> Wow really ? I had no issues . My local record store said its what they use to show albums and such and worked fine with me . Thats brutal though . I heard ProJect makes good players . Only plus side for mine was the converter . I have mp 3 s made for all the twenty one pilots record store day ones and will make one for blurryface live
