So what happens when you tune up to the next E ? Is it too tight ? If it is you most likely need an action adjustment . You can watch videos on how to setup your guitar or take it for a professional setup . Its fairly simple to setup your own guitar and you really can ' t do any harm . You just need to be careful with your truss rod . It sounds like this would be a good time do your first setup so if I was you I would give it a go ! EDIT Also , working on your guitar can be just as fun as playing it . I have some buddies who like to buy cheap low end guitars and I ' ll set them up for free our of pure enjoyment of just trying to make the most out of a cheap guitar . You can really edit your tone by the way you set it up .
