Don't buy one! Mine has totally fried itself after three months of not so loyal service. It wiped out all my user presets and froze when I tried to go to them, the factory presets no longer work, save for one, and the tuner decides when it wants to work. I used to carry a little pillow underneath it and carried it in its original box to keep care of it and still failed on me! And my friend has the same pedal except for guitar, only had it one month, and the tuner is even more messed up than mine! I feel that Digi Tech isn't such a quality product anymore. Anyone else have thoughts?
