Very unreliable and terribly inaccurate.

This is a very nice looking tuner. The display is bright and easy to read. I find it doesn't pick up the vibrations enough on my solid body guitars and gives me varied readings. However, it works just great on my hollow body electric and my acoustic with accurate readings. I'll definitely keep the Earnie Ball for those guitars, and my Snarks for the others.

unfortunate review

I generally really love the Ernie ball product line, they make really cool things although received this tuner a few days ago and the quality was cheap plastic, a swivel mechanism which constantly moves around, an easy scratch screen and the battery they gave me had only 1 bar battery life, super disappointing and unfortunately, my housemate threw away my packaging and I can't opt for a refund to purchase another tuner

prompt delivery and good value
