To quickly break-in a guitar, go to BreakingInGuitars.com.
You could wait for your guitar to “open up” on its own just by playing it, which is a pretty good plan. Or, you can speed up the process by a variation on The Speaker Method (vibrating your new guitar by playing music at it from your stereo speakers). At BreakingInGuitars.com you’ll find special tracks designed to speed up The Speaker Method.
Playing in a guitar naturally is good, this is good AND a little faster.
