excellent tuner. I use it for mandolin, banjo, guitar, weissenborn, and mountain dulcimer. extremely fast as well. ended up ordering more to replace some older(higher dollar) tuners I had in each instruments case.
This is a great tuner.... sleek, compact and easy to use. I haven't yet experimented with any of the features beyond the tuning function. Can't beat it for the price. Highly recommend it!!
