I use a Rubber/Cork/Rubber pad under my TT. This one is a 18" x 18" x 7/8" pad ( like the Isopads) and weights about 7 lbs. The Psychic knows the product because he got a pair the last time he visited our island. This pad is used under power transformers, heavy motors and other industrial equipment to isolate and/or reduce vibrations.
