I was looking for something that would allow me to change keys without having to re-learn a song. Unfortunately this device while pretty fun to play with, adversely affects the sound of your guitar too much to be usable for performances in the pitch shifting mode. If it allowed the original sound, or very close to original to come through while changing the pitch, I would give it 5 stars and would keep it. I have to send it back and look for something that better suits my needs.
