Here is the 1400 grams “Ebronzy” (Ebony/Bronze) clamp... African Ebony is 25 years old, natural dried, luthier-grade, as used for violin and guitar making.
I was very impressed by ebony sonics as it touches disc label area and sort-of tames bronze resonance. Very natural sound when compared to bronze-only clamp (my previous reference). A couple were made for personal use and two more were lathed... anyone?
