The USB port on the back of the mic seems to be glued with some sort of red cement. To the touch this glue is hard but rubbery. I’m pretty sure it’s only touching 2 metal parts (the port casing and the thin hexagonal nut) but it might be touching the plastic usb port. What is recommended to remove this glue? or is there another way to approach this problem and remove the port? Thanks.
I would just use a small knife to remove that adhesive that is securing the lock collar. It is likely there to keep the collar from moving, and to keep it into place.
