Hey, I have kinda a dumb question. I recently bought a String Swing to mount my guitar on the wall. So many years of stuffing it behind the couch when not in use, lol.
Anyway, I notice when I take it down to play (which is not very often these days) that the tuning on the guitar has usually gone a half-step or full step sharp. This is contrary to what I'm used to in other storage situations that I've known - freestanding, guitar stand, or case - where the guitar tended to go half a step flat after a prolonged period of disuse. Have never in my life had a guitar go sharp on me.
Is this common with String Swing-type wall hangers? If so, are there downsides to this?
