I recently Built a Music room, and have 2 basses, and 5 guitars. Not having a lot of wall decorations, and wanting to have easy access to my Babies, I bought hercules wall hangers for them all. I love the looks, but Is it bad for the Instruments. It did change the tuning on all, and they don't stay 100% in tune all the time like they did in the case's Can anyone Give an opinion????
