interesting 🤔 ... the stage I'm talking about is a particularly wobbly one that the drummer REALLY hates...
but it didn't seem to get the collective synchronization millennium bridge wobble going!
I will look out for it on other gigs though.
so far I've tested it on that gigs / stage I know well and a new venue with a concrete floor that I'm unsure if the iso mat did anything at all to improve tone
