Re: Edge Pro arm holder loosens by itself (weird)
Mine haven't loosened as of yet....if you are talking about the trem arm mount. If that is the case with yours, then the same procedure would apply. You'll have to take out the trem from the body, loosen the nut below the base and above it and then put some kind of thread locker in there and retighten both nuts above and below. I've had mine for a couple of years now and I use them daily. They've stayed tight, thankfully!
However, As far as keeping the arm tight in the socket, I haven't had that issue to deal with as of yet. You tighten the collar a bit more to keep it from swinging, but you probably know that, already.
