By far the best tuner I have ever owned. It is so responsive and accurate. It takes me no time at all to tune my basses. I found the mic pickup was just as accurate as the direct line in. I would like it a bit more if it had a power in option and didnt solely rely on batteries, but AAA batteries are pretty easy/cheap to get so it's not a big deal. Also makes it good for bringing along if jamming with friends.
