I've sometimes wondered what's the idea behind those "superlight" aluminum tail stops found on some LPs. Seems counter-intuitive; one would have thought a big heavy piece made of brass would provide better inertial characteristics to enhance sustain. Or is this a way of bleeding off some of the excessive sustain that LPs are renowned for (j/k ;))
Seriously though, what's the deal with these things? Anyone know the theory?
