Superstrat ringing/resonating

[banana hammock]

I have a strat with a floyd and it is ringing out after muting the strings. Did the usual foam around the springs on the back side. This cut out 80% of the ring. But there is still some around.

This is my only guitar with a full strat style pickguard. Could that or the pickups be vibrating and need damping? On my other guitars doing the springs on the back and maybe something behind the nut is all I ever need. But this one is being stubborn.

Maybe put some dampeners behind the nut. I've had notes ring from there too. But it sounds lile you have the main culprit covered.
