An alternative to grounding the tailpiece would be to use locking studs. Tonepros, Faber, and Guitarfetish all make these. http://www.tonepros.com/ss1-tonepros-standard-locking-studs/

Many people report better sustain with locking systems. I figured I would try one out and see for myself. The basic tone of the stock aluminum hardware is okay with me, so maybe I'll go with TonePros' new aluminum bridge. GuitarFetish offers brass locking bridges and tailpieces as an alternative. Faber offers a third alternative.

I plan to swap out the stock bridge on my SG Faded T with a TonePros. However, after communicating with customer service I learned that I'll have two options after NAMM 2018: ZAMAK (a zinc alloy and their current standard) or aluminum. I'm not foolish enough to ask "which would sound better" because that would be entirely subjective. But I wonder if anyone here has experience with different bridge materials who could say something about qualitative differences in tone between heavier and lighter bridge metals. Also, does heavier lead to more sustain, or is the issue more complicated?
