Dings shmings!
Dings and dents are part of playing your instrument. If you are buying an instrument to collect and keep in museum condition, then put it away in a perfectly humidified environment and forget you own it cause that is the only way it will never get dinged. If you bought the instrument to play, ignore the dings. That does not meant you have to pull it out when you need an oar for canoeing through white water.
Some folks are harder on their instruments than others. Some folks sweat the small things and some folks just play their instrumentā¦
I purchased a new Recording King RD-316 last year for playing bluegrass. At this point, it has more dings and dents on it than all of my other 23 guitar combined. Play like you mean it, I always say.
