Step one. Shake your head in consternation at your broken e string because you were tuning DOWN, not up, and it has no right to behave this way in such a circumstance.
Step two. Pour a glass of wine to fortify yourself for this important task.
Step three. Drink a toast to the brave high E string that lost its life in the glory of battle. Your body is broken but your memory lives on, O Fabled E String!
Step four remove the broken E string from the guitar.
Step five, drink a toast to the gallant service of strings B, G, D, A and low E! May your retirement be long and happy!
Step six, put on a new E string.
Step seven, drink a toast to the long and happy career of your new high E string.
Step eight: Repeat steps six and seven for the remaining five strings. Note: Don’t hesitate to pour more wine if needed. Taking care of your instrument is an important task and it’s worth doing properly.
Step nine, tune your guitar up.
Step ten, wiggle all your strings around profusely to get the play out. You guys, this is the one important step I am bringing to the table here. I learned it when I did setups in a music store. You don’t need to just play and tune and play and tune and play and tune and be sad for the first few days of your new strings. EMPLOY THE WIGGLE METHOD. But do not break any strings because that will send you back to step one.
Step eleven, tune your guitar up again.
Step twelve, drink a toast to your fine handiwork. You deserve it.
Step thirteen, play a fine drinking song on your new strings…
