How often do you change your guitar strings? Once a week? Once a month? Once a year? The vast majority of guitarists play a six string guitar in standard E tuning. It's a fairly basic, straight forward affair that most master quickly. The great thing about an acoustic guitar is its versatility. They are suitable to many musical styles and genres, are easy to care for, and easy to transport. The down side is when the guitar needs to be heard by more than a few people gathered in a small room. As a result, acoustic guitar pickups were developed that allow the guitar to be plugged into some sort of amplification.
You get on stage, plug in your acoustic guitar, tweak the sound and start playing. Things are rolling along fine, and then, suddenly, in the middle of the song, an obnoxious "honk" slaps you (and the audience) in the face! Earlier we talked about how many more ideas for songs will come our way by "turning on the radar" and adjusting our subconscious mind to be more "in tune" to the world around us.
