Second the shelf idea. Friend used chains and suspended a shelf anchored to the wall. So the back part of the shelf was bracketed and the chains supported the front part of the shelf and ran up and back to the wall. Isolated the unit well from foot fall.
Myrtle wood under TT
I have an acoustic Signiture Final tool TT. It sits on a Billy Bags stand. (Not a dedicated TT stand) I can bump the table just a little and the virations travel to the TT. Will 3 myrtle wood blocks help. I am low on cash. Mike
