The jack that accepts the guitar cord and holds the strap onto my Martin acoustic guitar has become so loose that I'm afraid the wires inside are being twisted.
I tried to get my arm in the sound hole with the strings off and I almost tore the front off of my guitar and I got my arm stuck in there.Even then I don't think I was withing 5" of the nut inside. The only thing I can think of is to find a smallish person with small hands and arms.Do they make a tool for this?
