If you have tuning problems, it may be the strings and not your guitar, according to the folks at String Stretcha. There are ways to stretch the strings using your fingers, but pulling on them at random places results in uneven stretch and using the “thumb and fingers” method takes a long time and causes a lot of pain. If you use the Stretcha tool, you can zip it up and down the strings in just five minutes and achieve a much more even stretch. And the tool has been tested in studios and on the road by professional guitar techs, who give the Stretcha a big non-sore thumbs up. You can find the Stretcha at retailers, but if you can’t wait to get your hands on one, you can order directly from String Stretcha for $14.50.
