Eventually, the bug is going to bite and you are going to want to enhance your guitar sound with pitch shifting and harmonizer effects. Of course, if you are a normal human being, you won’t likely be able to afford an Eventide Harmonizer. But, even if you don’t have a ton to spend on effects, you can still get your hands on a decent pedal or rack that can give you pitch shifting and harmonizer capabilities for a reasonable price. What is a harmonizer?

I hope this little demonstration about harmonizers and pitch shifters has been helpful. This is one of those types of effects that can dramatically change your overall sound if used properly. Also, be sure to check out many different types of harmonizers and pitch shifters before purchasing one. Although technology in this area has improved dramatically, the truth is that a lot of harmonizers on the market are simply not very good. So, you really have to watch what you get.
