Bottom line, some guitars "open up", some don't.
Some don't, and you will think they have. Some will..and you wont think they did.
Some will...and you won't like how they have changed.
It's a pretty safe bet that if you aren't thrilled with the way your guitar sounds now, you won't be in 6 months..or a year......or 5 years.....unless your tastes change.
Guitars are like shoes.
Don't buy them thinking "well, they are too tight now...but I bet they will stretch out in a few months. "
