In my repair shop, I am often asked how often a “truss rod” should be adjusted. Unfortunately, there is no clear response for this question. The truss rod is in place in case it is needed, not because it is needed. In an ideal world, your truss rod would never require an adjustment unless your instrument has a flexible neck and you are changing string gauges. In fact, older guitars did not have these rods, and the curvature of the neck was adjusted using different methods of fretting and re-fretting the instrument.
A guitar can buzz or rattle for many reasons. A large number of repairs that come into my shop are due to complaints of buzzing or rattling when the instrument is played. When these kinds of complaints arise, I like to have the musician play for me and show me what they are hearing themselves before I attempt to examine the instrument. I do this for a few reasons. The first is that I want to eliminate one of the common causes of buzzing: poor playing technique. Any accomplished player can tell you that technique is a major influence on how your instrument will sound.
Every day we are asked the question, "should I buy a case?" There are a few things to take into consideration. Are you going to leave the house with your instrument and how often? How is the instrument stored at home? How much do you like your instrument? Maybe you only paid $100 for your guitar. Hard shell cases cost that much. But if you invest in a case you could use your money in the future to buy an additional guitar instead of replacing the one you have. Just think about where that instrument is going to be going and how much protection it will need.
There are many factors and variables to take into account when purchasing a guitar. You can take your chances online or you can let us help you take the guesswork out of buying the guitar that is right for your needs.
