Pay special attention when looking forward to purchase a semi bass guitar. Most newbies tend to overlook the tuning machine, which plays an exquisite role in the long run. It is supposed to run smoothly and accurately, with no issues at all. Strings must wound in a precise and clear way around the post. Low quality tuning machines might work and provide an accurate result too. However, they will probably need more effort and time, so frustration will obviously kick in. Such problems are even more annoying if you are a beginner, so they risk taking all the fun away from you.
