I pulled my guitar out of the case the other day to use it and noticed that the phase button had nearly come out of my anthem system I had installed in my guitar in November. It was fine, to the best of my knowledge, when I put the guitar in the case the previous time but when I pulled it out this time it was like the button was broken and about to fall out. It is very loose and it will not stay in when you push the button in. The phase still works the best I can tell but it is sometimes hard to get it to engage because it is so loose. Has anyone else had this problem and what can I do to fix it? I am not rough on my guitars but this is my main guitar and it gets used live whenever I play live and also for practice.
