I have mixed opinions on these seven and eight string guitars that are all the rage these days. Today, many guitar manufacturers are producing more seven and eight string guitars than ever. There are even some companies who are commercially selling nine and ten string guitars. This is nothing new, but the extended range guitars have hit the mainstream allowing musicians to easily purchase them in any music shop. Before, these guitars had to be custom designed by companies that specialize in making personalized (and very expensive) guitars. Are standard tuning six-string guitars becoming extinct within the heavy metal music genre?
